Gross margin vs net margin is the difference between two cuts of the same income statement. Gross margin is gross profit divided by revenue, and gross profit is revenue minus the cost of goods sold (COGS). Net margin is net income divided by revenue, after operating expenses, interest, taxes and other below-the-line items have come out. Gross tells you whether the thing you sell can fund a business. Net tells you whether, after everything else, anything is actually left.

You’ll also hear gross profit margin and net profit margin. Same ratios. Neither one is cash in the bank, and both can move if you switch how you recognize revenue and costs. This is education, not a target I want you to chase, and not a valuation multiple.

The formulas, side by side

Gross profit equals revenue minus COGS. Gross margin equals gross profit divided by revenue. Net income is what remains after operating expenses, interest, taxes, and other income or charges. Net margin equals net income divided by revenue. People often multiply both by 100 to talk in percentages. The math does not change.

COGS is the cost of the product or service you delivered: materials, merchandise, and the direct labor tied to making or delivering the work, depending on how your books are set up. Operating expenses are the rest of running the company: rent, marketing, most salaries, software, insurance. Interest and taxes sit further down. If those categories are messy, the margins will be messy too, which is one reason cash vs accrual accounting is not a paperwork detail. The same shop can show a different gross margin once inventory and prepayments are recognized in the right period.

Operating margin, or operating income divided by revenue, sits in the middle. It takes out operating expenses but not interest and taxes. It’s useful, and it is not the same as net margin. If someone asks for “the margin” and doesn’t say which one, ask them to name the line.

A worked example

Take a labeled teaching example, not a real company’s books. Revenue is $200,000. COGS is $80,000. Gross profit is $120,000, so gross margin is 60%. Operating expenses are $90,000. Interest is $4,000. Taxes are $6,000. Net income is $20,000, so net margin is 10%.

Now change only the overhead. Keep revenue at $200,000 and COGS at $80,000, so gross margin stays 60%, but lift operating expenses to $125,000 and leave interest and taxes as they are. Net income falls to negative $15,000. The product still leaves 60 cents on the dollar after direct costs. The company is losing money because the operating load is too heavy for that volume.

Flip it the other way. Revenue is still $200,000, but COGS is $160,000. Gross margin is 20%. Even if you somehow held operating expenses, interest and taxes to $25,000, net margin would be only 7.5%. You cannot expense-cut your way out of a product that barely clears what it costs to deliver. That’s the founder use of these two numbers: gross margin diagnoses the offer, net margin diagnoses the whole machine.

What each number is trying to tell you

Watch gross margin when you change price, discounting, mix, suppliers, shipping, or how much work you give away inside a package. A slide in gross margin is often a sales or production problem wearing a friendly invoice. Watch net margin when you add headcount, rent a bigger space, raise ad spend, take on debt, or have a tax year that looks nothing like last year. You can have a healthy gross margin and a weak net margin. You can also have a thin gross margin that looks “fine” in a busy month until the first quiet one arrives.

Buyers and lenders read both, then they ask what sits underneath. A buyer looking at how to value a small business is not going to pay a premium for a net margin that only exists because the owner stopped taking a paycheck, or for a gross margin that depends on one supplier discount you may not keep. If owner’s compensation is missing from the P&L, net margin is flattered. If you buried contractor costs above or below COGS to dress up the ratio you prefer, both numbers are lying in different directions.

Benchmarks, with a source, not a target

I won’t give you a “good” margin to aim at. Margins vary by business model, and public-company averages are not a report card for a one-person firm. They are still useful as a sense of scale. Aswath Damodaran at NYU Stern publishes industry margin data each year. In the January 2026 update, covering 5,994 firms, the total-market average gross margin was 37.76% and the average net margin was 9.74%. Without financials, those figures were 34.39% and 8.56% across 4,822 firms.

The spread across industries is the point. In that same dataset, software (system and application), 309 firms, showed a 71.72% gross margin and a 25.49% net margin. Software (internet), 29 firms, showed a 62.58% gross margin and a minus 0.93% net margin: plenty of gross profit, and still no net profit on average. Business and consumer services (155 firms) came in at 33.38% gross and 7.03% net. Restaurant and dining (64 firms) was 32.24% and 9.37%. General retail (23 firms) was 33.18% and 5.61%. Grocery and food retail (15 firms) was 26.31% and 1.32%.

Those are public-company composites as of January 2026, not a forecast and not a goal for your shop. A private business can run higher or lower for reasons that have nothing to do with quality: owner’s pay, one-time costs, a different mix, or simply a smaller sample than a sector average. Use the data to ask a better question: if your gross margin is far from firms that sell something similar, is that a real advantage, a bookkeeping choice, or a problem you haven’t priced yet?

The usual ways these numbers lie

Mixing cash and accrual is the first. A big prepay can inflate a cash-basis month. Inventory you already paid for can hide in one period and land in COGS in another.

Stuffing or stripping COGS is the second. Move a contractor from cost of sales to overhead and gross margin jumps without the business changing. Do the opposite and it sinks. Pick a policy, write it down, and keep it still if you want year-to-year comparisons to mean anything.

Comparing yourself to the wrong industry is the third. A 30% gross margin can be normal in grocery and alarming in a software product with almost no delivery cost. Use a comparable set, or compare your company to itself over time.

Treating net margin as cash is the fourth. You can show a profit and still be short in the bank, or the reverse. And treating contribution margin as gross margin is a fifth, quieter mix-up. Contribution margin usually looks at revenue minus variable costs, which may not match COGS on the P&L. It’s a useful unit-economics tool, and it’s a different job, so I’m leaving the CAC, LTV and payback math for that article.

I look at both numbers, every time. If gross is weak, I start with price, mix and direct cost, not with a new productivity app. If gross is solid and net is thin, I look at overhead, debt and whether the owner’s pay is even on the page. One margin without the other is how a decent business tells you only half the truth.

FAQ: Gross margin vs net margin

What is the difference between gross margin and net margin?

Gross margin is gross profit divided by revenue, after COGS only. Net margin is net income divided by revenue, after operating expenses, interest, taxes and other items. They measure two different cuts of the same P&L.

How do you calculate gross margin?

Subtract cost of goods sold from revenue to get gross profit, then divide gross profit by revenue. In a teaching example with $200,000 of revenue and $80,000 of COGS, gross profit is $120,000 and gross margin is 60%.

How do you calculate net margin?

Divide net income by revenue. Net income is what’s left after COGS, operating expenses, interest, taxes and other income or charges. Using the same $200,000 revenue example with $20,000 of net income, net margin is 10%.

Is a higher gross margin always better?

Not by itself. A higher gross margin means more of each sales dollar is left after direct costs, but it can still be paired with overhead that wipes out net profit. Compare the ratio to your own history and to similar businesses, not to a universal target.

What is a good net margin for a small business?

There isn’t one number that fits. NYU Stern’s January 2026 public-company dataset shows a total-market average net margin of 9.74%, with a wide spread by industry. Treat that as context, not a goal for a private firm.

Is operating margin the same as net margin?

No. Operating margin is operating income divided by revenue, after operating expenses but before interest and taxes. Net margin is after those items too.

Professional liability (E&O) insurance, also called errors and omissions insurance, is coverage for claims that your professional advice, work or services caused a client a financial loss. It is aimed at mistakes, missed work or alleged negligence in the service you were hired to provide, not at a customer who slips in your office or a shareholder who sues the board. Many of these policies are written on a claims-made basis, so the policy in force when the claim is made, the retroactive date and continuous coverage matter as much as the limit on the declarations page.

You’ll also hear it called E&O, professional indemnity or a professional liability policy. Same idea. If you consult, run an agency, design, advise or sell expertise, this is often the policy a client contract will ask for. It is not a substitute for a clear contract, and it is not a reason to pick a carrier from a blog post. This is education, not insurance advice. Talk to a licensed broker about your actual services and your contracts.

What professional liability insurance actually covers

The claim that belongs here is a financial-loss claim tied to your work. A client says your strategy was wrong, your report missed something material, you delivered late, or your work didn’t meet the professional standard they believe they paid for, and they want to be made whole. Even a weak claim can be expensive to defend. A professional liability policy is built to respond to those allegations, including defense, subject to the terms, exclusions and limits of the specific form.

It is not a blanket for every unhappy client. Policies define covered professional services, often by listing them. If you add a new service and never update that description, you can have a gap. There are usually exclusions, which can include fraud, intentional acts, bodily injury, some contractual liability, and other lines of coverage that belong on a different policy. This is also not cyber insurance. A data breach, ransomware event or privacy claim is a different exposure, even if it happens while you’re doing client work. Read the form, or have a broker walk you through it, before you assume a situation is covered.

Two mechanics on the form are worth asking about out loud. First, do defense costs sit inside the limit or outside it? If they’re inside, legal fees can eat the amount left to pay a settlement. Second, is the policy written for the services named on the declarations page, and is that list current? Neither answer is the same on every form, which is why a comparable-quote conversation with a broker beats a generic limit you saw in an ad.

Here’s a simple teaching example, not a real case. You’re a marketing consultant. You deliver a campaign plan. The client later says the plan failed and sues for the money they spent and the sales they claim they lost. That is the kind of professional-services claim E&O is meant to address. If that same client trips on a cable in your studio and breaks a wrist, that is a general liability problem. If your investors sue the board for a growth decision, that is a management claim, which is why companies buy D&O insurance for startups.

How E&O differs from general liability and D&O

People mix these up because all three have the word liability in them. They do different jobs.

General liability is the policy for physical harm and damaged property, and sometimes certain personal or advertising injury claims, depending on the form. It is not designed to stand in for E&O. D&O is for the people running the company, not for the work product you sold a client. A firm can need more than one of these. This page is only about professional liability. A wider map of what business insurance do you actually need belongs on its own page.

Why claims-made coverage, retroactive dates and gaps matter

Most professional liability policies are claims-made. Industry references such as the IRMI definition of professional liability explain the trigger: coverage generally depends on when the claim is first made and reported, not only on when the work was done. A retroactive date, sometimes called a prior-acts date, then limits how far back that work can go. A claim about work performed before the retroactive date is typically excluded, even if the claim arrives while the policy is in force.

That is why continuous coverage matters. If you let a claims-made policy lapse, or you switch carriers and allow the retroactive date to move forward, you can lose protection for earlier work. A client can sue two years after a project ends. The policy you need is often the one in place when they sue, covering work back to a retroactive date you kept intact.

If you close the business, sell it, or change to a form that doesn’t pick up prior acts, ask about an extended reporting period, often called tail coverage. It can let you report later claims about earlier work after the policy ends. Whether it’s available, what it costs, and how long it lasts are policy-specific. Don’t guess. Get those answers in writing before you cancel or switch.

When a client contract will require it

This is often how founders first meet E&O. A master services agreement, a government contract or an enterprise vendor packet asks for professional liability insurance, sometimes with a minimum limit, a certificate of insurance, and extra requirements such as being named as an additional insured or receiving notice of cancellation.

Read those insurance exhibits the way you read the rest of the contract. Can you actually buy what they’re asking for? Does the requirement match the services you’re providing? If you can’t meet a term, fix it before you sign, or don’t sign. A contract that requires a policy is not the same thing as a policy that will cover every dispute under that contract. Limitation-of-liability clauses, a tight scope of work, and good records still matter. Insurance is not a substitute for that.

How to think about buying it, without a hard sell

I can’t tell you a premium or a “standard” limit, because those numbers depend on your services, revenue, contracts, claims history and the market, and they go stale fast. Anyone publishing a neat price band in an article is guessing, or selling.

What I would do is simpler. Write down the services you actually sell. Collect the insurance requirements already in your contracts. Sit down with a licensed broker who can explain the form, the exclusions, how defense costs interact with the limit, the retroactive date, and what happens if you add a service or shut the company down. Stay carrier-neutral until you have quotes on comparable terms. Then buy the policy that fits the work, keep it in force, and calendar the renewal so you don’t create a gap by accident. If a client later alleges a mistake, tell your broker and the carrier promptly. Claims-made policies are picky about when a claim is reported, and waiting to see if it “blows over” is a good way to turn a covered problem into an unreported one.

I’m not your broker, and this isn’t a recommendation of any insurer or a promise that a given claim would be covered. Policy language controls. Use a licensed professional who can apply it to your business.

Frequently asked questions

What is professional liability (E&O) insurance?

It’s insurance for claims that your professional advice, work or services caused a client a financial loss, including alleged errors, omissions or negligence in those services, subject to the policy’s terms and exclusions.

Is E&O insurance the same as general liability?

No. General liability is aimed at bodily injury and property damage. Professional liability is aimed at financial loss from your professional services. One is not a substitute for the other.

How is professional liability different from D&O insurance?

D&O protects directors and officers against claims about how the company was managed. Professional liability protects against claims about the services you provided. Many D&O forms exclude professional-services claims.

Why does the retroactive date matter on an E&O policy?

Most E&O policies are claims-made. The retroactive date is the earliest date of work the policy will consider. Claims about work done before that date are typically excluded, even if the claim is made during the policy period.

Do I need tail coverage if I close my business?

Ask your broker before the policy ends. An extended reporting period, or tail, can let you report later claims about earlier work after the claims-made policy expires. Availability and length depend on the policy.

Can a client require professional liability insurance in a contract?

Yes. Many consulting and vendor contracts require E&O, sometimes with a minimum limit and a certificate of insurance. Review those requirements with a broker before you sign, and don’t assume the policy will cover every dispute under the contract.

A term sheet is a short, mostly nonbinding outline of a priced investment. The lead investor uses it to put valuation, the size of the check, the option pool, liquidation preference, pro rata rights, board seats and other control terms on one or two pages before anyone drafts the full legal documents. Carta’s fundraising guide, updated October 7, 2026, describes it as a preliminary framework for a priced round, most often at Series A and later, though a seed round can use one too.

You’ll also hear offering terms, a Series A term sheet or, loosely, “the deal memo.” Signing it is not the same as closing the round. A purchase of an existing company usually starts with a letter of intent to buy a business, which has its own rules about what is binding. A few clauses, usually confidentiality, a no-shop (exclusivity) window and a promise to negotiate in good faith, can be binding from the moment you sign. This is education, not legal advice. Have a startup attorney read the document before you agree to it.

What is, and is not, binding

Carta’s guide is clear on the split, and it matches what most counsel will tell you. The economic and control terms are a negotiated outline. Either side can generally walk away before the definitive agreements are signed, which is the point of starting with a short document instead of a 100-page set of contracts.

The binding pieces are the ones that restrict your behavior while you talk. A no-shop clause, for a defined window, says you will not solicit or negotiate competing offers. Confidentiality says you will not publish the terms or the diligence you exchange. Good-faith negotiation says you will actually work toward closing, not use the paper as a prop. The length of the no-shop is one of the terms Carta lists as commonly negotiated. Do not sign a long exclusivity period just to “keep the process moving.”

Valuation, the check size and the option pool

Pre-money valuation is what the company is worth, for this deal, before the new money goes in. Post-money valuation is pre-money plus the new investment. If an investor puts in $10 million at a $40 million pre-money valuation, the post-money valuation is $50 million, and that check is 20% of the company on a post-money basis, before you layer in other adjustments.

The option pool is one of those adjustments, and it is often where a clean-looking valuation gets less clean. The term sheet reserves a block of shares for future hires. Investors often want that pool created or topped up on a pre-money basis, which means existing holders, usually the founders, absorb the dilution before the new money is counted. The same headline pre-money number with a larger pre-money pool is a worse deal for the people already on the cap table. Carta’s guide flags pool size, and whether it is carved out pre- or post-money, as a term founders commonly negotiate, and Carta data there suggests founders can start a pool at 8% to 10% of equity and expand it later rather than taking all of that dilution up front.

A priced round also changes how you grant options going forward. The preferred price is not automatically the fair market value of the common stock. That is why companies get a 409A valuation after a financing, so new grants are priced against an independent appraisal of the common, not against the preferred issue price. And the pool on the term sheet only helps you if you actually grant those options under the right type of award, which is a separate decision we already cover in ISO vs NSO.

Liquidation preference, with a worked example

Preferred stock gets paid before common in a sale, a winding up, or a “deemed liquidation” such as a merger, unless the preferred holders elect otherwise. The NVCA model documents, which are the industry’s standard starting templates, offer more than one way to write that preference. Carta’s October 2026 guide treats a 1x non-participating liquidation preference as a usual standard term, with participating versus non-participating as something founders still negotiate.

Non-participating means the investor chooses the better of two paths: take the preference (typically their money back, or a multiple of it), or convert to common and take their ownership percentage of the proceeds. They do not get both. Participating preferred takes the preference first, then also shares in what is left, as if they had converted. That second bite is why founders push back on it.

Here is a labeled teaching example, not a real deal. An investor puts in $5 million at a $15 million pre-money valuation. The post-money valuation is $20 million, and the new preferred owns 25%.

• If the company later sells for $8 million and the preferred is 1x non-participating, the investor takes the $5 million preference. Common splits the remaining $3 million.
• If the company sells for $40 million, 25% as-converted is $10 million, which is better than the $5 million preference, so the investor takes the as-converted path.
• If the company sells for $20 million and the preferred is 1x participating, the investor takes $5 million first, then 25% of the remaining $15 million, or $3.75 million, for $8.75 million in total. Under 1x non-participating, that same $20 million sale would have paid the investor $5 million (the preference and the as-converted amount are the same). The extra $3.75 million is the cost of participation.

A 2x or 3x preference, or participating preferred with no cap, can wipe out common in a modest exit. Carta data cited in that October 2026 guide shows the down-round rate fell to 11.4% in the first quarter of 2026, from a peak of about 22% in 2023, and notes that liquidation preferences and participation rights were near multi-year lows. That is a dated snapshot, not a promise that an aggressive term will not show up in your deal.

Pro rata, anti-dilution and the control terms

Pro rata rights let a major investor buy enough shares in a later round to keep their ownership percentage. They live in the investor rights documents, and they are one of the terms Carta calls usually standard. They matter because a lead who can keep taking their share will still be on the cap table when you raise again, for better and for worse.

Anti-dilution protection adjusts the preferred’s conversion price if you later sell stock at a lower price. NVCA-style term sheets typically offer a weighted-average adjustment, which spreads the hit across the new shares issued, or a full ratchet, which resets the conversion price all the way down to the new lower price. The full ratchet is the aggressive version. I would not accept it without a clear reason and a lawyer in the room.

Control is the other half of the paper. The term sheet usually sets how many board seats the preferred can appoint, how many the common (often the founders) keep, and how an independent seat, if there is one, gets filled. Carta lists board composition and who controls the independent seat as commonly negotiated terms. Protective provisions are veto rights, not day-to-day management: selling the company, issuing senior stock, taking on large debt, changing the charter, and sometimes hiring or firing senior executives or expanding the option pool. Drag-along rights can require minority holders to vote in favor of a sale if a stated majority agrees. None of these should be skated past because the valuation looks good.

After you sign, the real documents start

Carta’s sequence is the right one to keep in your head. Signing starts due diligence, not a close. Investors will review the cap table, contracts, intellectual property, financials and the story you sold them. Then counsel drafts the definitive agreements, typically a stock purchase agreement, an amended charter, an investors’ rights agreement, a voting agreement and right-of-first-refusal or co-sale documents. The round is not done until those are signed and the money is wired.

The National Venture Capital Association publishes model versions of these documents, including a model term sheet, at no charge. They are a reference, not a substitute for counsel who will mark up the actual paper in front of you. If two term sheets show up, that leverage usually matters more than a clever rewrite of a single clause. If only one shows up, do not let speed replace a careful read of preference, the option pool and the board.

Frequently Asked Questions

What is a term sheet in a startup financing?

A term sheet is a short outline of a priced investment, covering valuation, the check size, the option pool, economic rights such as liquidation preference and pro rata, and control terms such as board seats. It is mostly nonbinding, except for clauses like confidentiality and a no-shop window.

Is a term sheet legally binding?

Most of it is not. Either side can generally walk away before the definitive agreements are signed. Confidentiality, exclusivity (a no-shop period) and a good-faith negotiation clause are often binding once you sign. Have a lawyer confirm which sections bind you.

What is a 1x non-participating liquidation preference?

It lets preferred holders take the better of their money back (1x) or their as-converted share of the sale proceeds, not both. Participating preferred takes the preference first and then also shares in what remains. The NVCA model documents include both alternatives.

How does the option pool affect a term sheet valuation?

If the pool is carved out of the pre-money, existing holders absorb that dilution before the new investment is counted, which makes the same headline valuation worse for founders. Carta’s October 2026 guide flags pool size and pre- versus post-money treatment as a commonly negotiated term.

When do startups use a term sheet?

Term sheets are typical in a priced equity round, most often at Series A and later. A seed round can use one, but earlier raises are often done on a SAFE or a convertible note, which do not set a firm valuation in the same way. After a priced round closes, some companies also look at venture debt as a way to add runway without selling another large primary.

What happens after you sign a term sheet?

Due diligence begins, then counsel drafts the definitive agreements. The financing is not closed until those documents are signed and the funds are wired. Treat the signature as the start of that work, not the finish line.

The Profit First method is a cash-management system created by Mike Michalowicz in his book Profit First. It flips the usual formula. Instead of Sales minus Expenses equals Profit, you take a predetermined percentage of every deposit as profit first, then owner’s pay and tax, and you run the company on what’s left. The mechanics are a set of bank accounts and a twice-a-month transfer rhythm, not a new way to keep your books.

You’ll also hear it called Profit First accounting or the Profit First cash system. Same idea. It is not GAAP, and it is not a tax method. The value is behavioral: if the operating account is smaller, you spend less. This is education, not tax or accounting advice. Talk to a CPA or bookkeeper before you change how you pay yourself or set aside money for taxes.

Sales minus profit equals expenses

Michalowicz’s argument, in the book and in his TEDx talk, is that the standard accounting formula leaves profit as a leftover, and leftover is where the trouble starts. He points to Parkinson’s Law: a resource expands to fill the space you give it. If the checking account looks fat, expenses rise to meet it. He borrows the “small plates” idea from portion control and the envelope system from personal finance, then applies both to the business bank account.

I buy the psychology. I’ve watched too many operators treat one operating account as a scoreboard, pay whatever bill is loudest, and then act shocked when April arrives empty. Taking profit first does not invent profit that isn’t there. It puts a fence around cash so you notice the shortfall while you can still cut spending, raise prices or change the work, instead of discovering it on a tax bill.

The five Profit First accounts

The method uses five accounts at whatever bank will let you open them. You do not need a special app or a branded bank to do this.

Income. Every customer payment lands here first. You don’t pay rent, payroll or software out of this account. It’s a holding tank until allocation day.

Profit. A set percentage of each allocation is moved here before you fund operations. This is meant to be a reward and a reserve, not a second checking account you raid whenever a bill feels tight. A business emergency fund is a different cushion: cash you keep for shocks, not a pot you raid for ordinary bills.

Owner’s Pay (sometimes called Owner’s Comp). This is the account that funds what you take home for the work you do. It is not automatically the same thing as a W-2 wage, an owner’s draw or an S corporation distribution. Those labels have tax consequences. For the difference between a wage, a draw and a distribution, see how to pay yourself as a business owner.

Tax. A percentage of real revenue is set aside so quarterly estimates and year-end balances aren’t a scramble. Michalowicz’s published starting point is 15% of real revenue. His own site is clear that a tax professional may tell you 15% isn’t enough, because they are looking at profit on the P&L, not cash as it arrives. Don’t treat 15% as a guarantee. Your entity, your state and your personal situation change the bill.

Operating Expenses (OpEx). What’s left after the other transfers is the money you actually run the business on: rent, payroll, tools, contractors who aren’t being stripped out of real revenue, and the rest of the bills.

Some firms add a sixth account for materials, inventory or subcontractors. That’s useful if those costs are large and irregular. The point is the same: money gets a job before it can wander.

How the 10th and 25th split actually works

Michalowicz’s published rhythm, which he calls the 10/25 rule on his FAQ, is to let deposits collect in Income, then allocate twice a month, commonly on the 10th and the 25th. On those days you move money from Income into Profit, Owner’s Pay, Tax and OpEx using your percentages, and Income goes back toward zero. Bills get paid from OpEx. You pay yourself from Owner’s Pay. Tax money stays put until a due date.

For businesses under $250,000 in real revenue, a starting target allocation he publishes is 5% profit, 50% owner’s pay, 15% tax and 30% operating expenses. Those four numbers add up to 100% of real revenue, not of gross deposits if you have heavy materials or subcontractor costs. Here’s that split on a $10,000 allocation:

That table is a teaching example of his starting target, not a recommendation for your company. If 30% would bounce payroll next week, you do not jump there on Monday. Michalowicz distinguishes current allocation percentages (where you actually are) from target allocation percentages (where you’re aiming). You close the gap a point or two at a time, often quarterly, rather than blowing up cash flow to match a chart.

His Instant Assessment, included with the book, uses a grid that changes as real revenue grows. Owner’s pay as a share of revenue usually shrinks once you hire a team that does the work you used to do yourself, and the operating-expense share rises. Use his current assessment for the band you are in, not a blog’s copy of the table and not a percentage you borrowed from a friend in a different business.

Real revenue, and why the tax account still needs a CPA

Allocations are supposed to be a percentage of real revenue, which Michalowicz defines as total revenue minus materials and subcontractor costs. If you’re a consultant with almost no COGS, real revenue and top-line revenue are close. If you’re a contractor, an agency that white-labels work, or a shop that buys inventory, allocating against gross deposits will starve OpEx or overfund profit and tax. Subtract the pass-through costs first, then split what’s left.

The tax account is a cash reserve, not a filing strategy. It does not replace estimated-tax calculations, payroll withholding or a year-end projection. If you are self-employed and already sending money to the IRS four times a year, that reserve should fund quarterly estimated taxes for the self-employed, not get spent the first week a client pays late. A CPA or enrolled agent should set the percentage to your actual liability, then you use the account so the cash is there when the payment is due.

One more boundary, especially if you have an S corporation: Profit First’s “owner’s pay” and “profit” buckets are cash labels. They are not a workaround for reasonable compensation, payroll taxes or the way distributions are supposed to work. Get the cash habit and the tax treatment in the same conversation, not two separate fantasies.

When the Profit First method breaks

It breaks when the business has no spare cash to allocate. A pre-revenue company, or one that’s barely covering payroll, cannot pretend a 5% profit transfer is happening just because a book said so. In that stretch, a tiny profit percentage or a temporary pause is more honest than bouncing rent to look disciplined.

It also breaks on lumpy revenue. Project firms, seasonal shops and agencies with a few large invoices can look rich on the 10th and broke on the 25th. A twice-a-month split of the last two weeks’ deposits is a poor substitute for a longer cash view. Those businesses often need a materials or project account, and they need to plan around the slow months, not only the fat invoices.

Debt service and past-due taxes do not care about your profit account. If you owe back payroll tax or a loan payment, that cash already has a job. Parking it under a “profit” nickname doesn’t change the obligation.

The system also fails when you treat the profit account as a slush fund. If you transfer 5% in and pull 5% back out every time a bill feels uncomfortable, you built a more complicated checking account. The fence only works if it stays up most of the time.

Last, it breaks when you confuse five bank balances with a P&L. Cash can look healthy in the accounts while accrual profit is negative, or the opposite. You still need books, and you still need someone who can read them.

My honest verdict

I’d use the skeleton. Income as a holding tank, a tax account you don’t raid, a real owner’s-pay habit, and some profit taken first, even if it starts at 1%. The flipped formula is a useful constraint. It makes overspending visible while you can still do something about it.

I would not treat the published percentage grid as scripture. I would not replace a bookkeeper with five account nicknames. And I would not skip tax planning because a popular book made cash feel simpler than it is. The Profit First method works when you treat it as a behavior system with a human reviewing the numbers. It breaks when you treat it as magic.

FAQ: Profit First method

What is the Profit First method?

It’s Mike Michalowicz’s cash system: you allocate a set percentage of each deposit to profit, owner’s pay and tax first, then run the business on the remainder, usually through five bank accounts and a twice-a-month transfer rhythm.

How many bank accounts do you need for Profit First?

The standard setup is five: Income, Profit, Owner’s Pay, Tax and Operating Expenses. Some businesses add a materials, inventory or subcontractor account. Any bank that will open multiple accounts can be used.

What are the Profit First percentages?

They vary by real-revenue range. A starting target Michalowicz publishes for firms under $250,000 is 5% profit, 50% owner’s pay, 15% tax and 30% operating expenses. Start near your current reality and move toward the target gradually.

Does the Profit First method work for a new business?

The account structure can, but aggressive targets often can’t. If cash is tight, a very small profit percentage, or a short pause on the profit transfer, is more honest than bouncing bills to match a chart.

Is Profit First a tax strategy?

No. The tax account is a cash reserve so you can pay the bill. It does not change what you owe. A CPA should set the percentage to your actual liability and entity type.

What’s the difference between owner’s pay and profit in Profit First?

Owner’s pay is cash set aside for the work you do. Profit is a reserve and a reward taken off the top. Those are cash labels, not automatic tax categories like wages or distributions.
