Net Income Calculator – What Your Business Really Keeps After Every Cost
Revenue is the headline; net income is the truth. This calculator walks your numbers down an income statement — revenue, minus the cost of goods sold, minus every operating expense, interest and tax — until only the bottom line is left, together with the net profit margin it represents. Built for businesses, freelancers with a P&L, and anyone reading a profit and loss statement.

First, one thing this page is not. This is the business meaning of net income — profit after business costs and business tax. It is not the amount that lands in an employee’s bank account from a paycheck. If you want your salary after tax and deductions instead, use the Take-Home Pay Calculator or the Salary Calculator — different question, different page.
Your bottom line
The income statement, line by line
What this means
After every cost of running the business — the goods themselves, the day-to-day expenses, interest and tax — $55,300 of the $250,000 is left as profit. Roughly 22 cents of every revenue dollar survived the whole trip down the statement.
How the tax line works: the rate you entered is applied to profit before tax (operating income minus interest). When that profit is zero or negative, the tax line is $0 — a loss-making period produces no income tax in this simple model, though real filings can differ (loss carryforwards, minimum taxes and state rules are beyond a quick calculator).
- Net income is revenue minus the cost of goods sold, operating expenses, interest and tax — the bottom line after every cost on the statement.
- The net margin says how much of each revenue dollar survived the whole trip: 22.12% on the default statement means roughly 22 cents per dollar.
- A loss is not one verdict — find the rung where the statement turned negative, because each rung has a different fix.
Watch revenue become the bottom line
Each bar is what survives a stage of the statement. Revenue steps down to gross profit once the goods themselves are paid for, down again to operating income once the running costs come out, and what is left after interest and tax is net income. Change any figure above and the waterfall redraws itself.
| Step | Line | What it means |
|---|---|---|
| 1 | Revenue − COGS = Gross profit | What is left after paying for the goods or direct work you sold |
| 2 | Gross profit − Operating expenses = Operating income | What the core business earns before financing and tax enter the picture |
| 3 | Operating income − Interest = Profit before tax | The cost of borrowed money comes off next |
| 4 | Profit before tax − Income tax = Net income | The bottom line — divided by revenue, it is also the net profit margin |

How it works
Start with everything the business took in
Revenue is every sale in the period, before anything is subtracted. Then the cost of goods sold comes off — the stock, materials and direct labour that those sales consumed — leaving gross profit.
Take off the cost of running the place
Rent, salaries, marketing, insurance, software and the rest of the operating expenses bring gross profit down to operating income. Interest on loans comes off next, because it is a cost of how the business is financed, not of how it trades.
Tax whatever profit is left
The tax rate you enter is applied to profit before tax. What remains is net income — and divided by revenue, it becomes the net profit margin, the single most quoted measure of how profitable a business really is.
The formula, and one worked example
Net income = Revenue − COGS − Operating expenses − Interest − Income tax
Worked example. A small business takes in $250,000 of revenue. The goods it sold cost $120,000 to buy and make, so gross profit is $130,000. Operating expenses — $25,000 of rent, $18,000 of salaries, $9,000 of marketing and $8,000 of other costs — total $60,000, leaving operating income of $70,000. There is no loan interest this year. Tax at 21 percent of $70,000 is $14,700, so net income = $70,000 − $14,700 = $55,300, and the net profit margin is $55,300 ÷ $250,000 = 22.12 percent.
Going deeper
People say “profit” as if it were one number, but an income statement is a ladder of them, and each rung answers a different question. Gross profit asks whether the thing you sell is priced above what it costs to make. Operating income asks whether the whole operation — premises, people, marketing — pays for itself. EBIT (earnings before interest and tax) is operating income by another name in most simple statements, used to compare businesses regardless of how they are financed. Profit before tax is what is left after the lenders have been paid their interest. And net income is the only rung that has met every cost, which is why it is called the bottom line. Confusion between the rungs is expensive: a business can have a healthy gross profit and still lose money overall, because the rungs in between quietly ate the difference.
Business tax is not one system; it is several wearing the same coat. A US C corporation pays a flat 21 percent federal rate on its profit, plus whatever its state adds. A sole proprietor, partnership, LLC or S corporation usually pays no business-level income tax at all — the profit flows onto the owners’ personal returns and is taxed at their rates, on top of self-employment tax for many of them. Two businesses with identical statements can therefore owe very different tax, and any calculator that silently assumed one rate would be confidently wrong for the other. So this page asks you for the effective rate that fits your setup and applies it transparently, in the open, where you can change it. If you do not know yours yet, last year’s tax bill divided by last year’s profit before tax is a solid estimate.
Five statements, five lessons
One worked example teaches the route down the statement. Five teach what moves the answer. Every figure below was run through the calculator above, starting from its default statement — $250,000 of revenue, $120,000 of cost of goods sold, $60,000 of operating expenses, no interest, and a 21% tax rate — and changing one thing at a time. Nothing here is a forecast; each row is the same arithmetic the calculator performs, with a single input changed so you can see exactly which line did the work.
| What changed | Gross profit | Operating income | Net income | Net margin |
|---|---|---|---|---|
| Default statement, nothing changed | $130,000 | $70,000 | $55,300 | 22.12% |
| Tax rate set to 0% | $130,000 | $70,000 | $70,000 | 28.00% |
| Interest of $10,000 added | $130,000 | $70,000 | $47,400 | 18.96% |
| Cost of goods sold raised to $200,000 | $50,000 | −$10,000 | −$10,000 | −4.00% |
| Revenue cut to $100,000, costs unchanged | −$20,000 | −$80,000 | −$80,000 | −80.00% |
The default statement is worth reading as a ladder, not just a total. Gross profit is $130,000, which is 52.00% of revenue: a little over half of every sales dollar survives the cost of the goods themselves. Operating income is $70,000, or 28.00%: the day-to-day running costs — rent, salaries, marketing and the rest — take 24 percentage points of the ladder between gross profit and operating income. Tax then takes $14,700 of the $70,000, leaving the net margin of 22.12%. Each rung answers a different question, and a business that only watches the bottom rung will not know which question went wrong when the answer moves.
The tax-rate row is the cleanest demonstration of why this page asks you for a rate instead of assuming one. At 0% the net income is the whole $70,000 of operating income and the margin is 28.00%; at 21% it is $55,300 and 22.12%. The difference — $14,700 — is exactly 21% of $70,000, and it is also the whole reason two businesses with identical statements can report different bottom lines. A C corporation paying the flat 21% federal rate, a pass-through owner taxed at personal rates, and a business in a state with its own additional tax are not three versions of the same answer; they are three different tax lines applied to the same profit before tax. If you change the rate in the calculator and nothing else moves, that is the point: the rate only ever touches the last step.
The interest row shows the same isolation one step higher. Adding $10,000 of interest leaves gross profit and operating income untouched at $130,000 and $70,000, because interest is a cost of how the business is financed, not of how it trades. Profit before tax falls to $60,000, tax at 21% falls with it to $12,600, and net income lands at $47,400 with a margin of 18.96%. So a business can borrow more, pay more interest, and still report the same operating income — the damage only shows up below that line. That is precisely why lenders and buyers quote operating income alongside net income: it lets them compare two businesses as trading operations before financing choices blur the picture.
The last two rows are the warning. When the cost of goods sold rises to $200,000, gross profit is still positive at $50,000 — the goods still sell for more than they cost to make — yet operating income is already −$10,000 once the $60,000 of running costs is subtracted, and net income is −$10,000 with a margin of −4.00%. A positive gross profit did not save the business; the rungs in between ate it. And when revenue falls to $100,000 with every cost unchanged, the damage compounds in the other direction: gross profit itself turns negative at −$20,000 because the cost of goods sold alone is bigger than revenue, and the statement ends at −$80,000, a margin of −80.00%. The calculator flags that case plainly — the cost of goods sold alone exceeding revenue is a prices-or-supplier problem, not a rounding problem — and a negative margin here is a loss, not an error in the arithmetic.
One more behaviour of the loss rows deserves stating, because it surprises people. In both loss cases the calculator charges no income tax: net income equals operating income exactly (−$10,000 and −$80,000), with no tax line reducing the loss further. That follows from the page’s own rule — tax is a percentage of profit before tax, and there is no profit to tax. In real life a loss-making business may be able to carry a loss forward against future profits under the tax rules that apply to its structure, but this calculator does not model carryforwards, credits or refunds; it simply shows the statement for the period you entered, with tax at zero when the period made no profit.
Reading the margin, and where net income misleads
A net margin of 22.12% means roughly 22 cents of every revenue dollar survived the whole trip down the statement. That sentence is the most useful way to carry the number into a conversation — with a lender, a partner, or yourself at year end — because it strips away the size of the business and leaves only efficiency. A business with $250,000 of revenue and $55,300 of net income and a business with $2,500,000 of revenue and $553,000 of net income have the same margin, and in margin terms they are equally good at turning sales into profit. But the margin is a ratio, and ratios hide scale: the bigger business still has ten times the profit to reinvest, to absorb a bad quarter, or to pay down debt. Never compare margins without also looking at the dollars, and never compare dollars without also looking at the margin.
Margins also refuse to be judged without context. There is no single good margin for every business, because different kinds of business carry structurally different cost ladders. A business selling its own labour has little cost of goods sold and a high gross margin; a business reselling physical stock has a heavy cost of goods sold and a lower one, and neither is doing anything wrong. What matters is the direction of your own margin over time, and the rung at which it changed. If gross margin fell, the problem is pricing or supplier cost. If gross margin held but operating margin fell, the problem is in the running costs — rent, people, marketing. If operating margin held but net margin fell, the problem is financing or tax. The calculator’s ladder exists so that a falling bottom line can be traced to the rung where it started falling, instead of being blamed on the business as a whole.
There are also three things net income is not, and confusing them with it causes real mistakes. First, net income is not cash in the bank. A business can report a profit while its bank balance falls, because customers who have not paid yet still count as revenue, stock bought for next quarter still counts as a cost only when sold, and loan repayments of principal never appear on the income statement at all. Equally, a business can report a loss in a year when cash rose, because it collected last year’s invoices. The income statement measures what was earned in the period; the bank balance measures what has arrived. Second, net income is not what the owner takes home. In a company, profit belongs to the company until it is paid out as salary or dividend, and both of those have their own tax treatment; in a pass-through business, the profit is taxed on the owner’s return whether or not the cash was withdrawn. The calculator shows the business’s bottom line, not any individual’s spendable income. Third, net income for a single period is not the trend. One good quarter can hide a deteriorating gross margin, and one bad quarter can hide a business that is actually improving; the statement above is a snapshot, and snapshots mislead when they are read as stories.
A practical way to use this page, then, is to run it three times: once for last year, once for this year, and once for the year you are planning. Keep the same line structure each time, so the three statements are comparable rung by rung, and watch the margins rather than only the totals. If the gross margin is steady and the net margin is falling, look at operating expenses, interest and tax in that order — the ladder tells you which one moved. If the net margin is steady but the dollars are shrinking, the problem is volume, not efficiency, and cutting costs may not be the answer. And if the calculator shows a loss, read the statement before reacting to the headline: a loss that starts at gross profit is a pricing problem, a loss that starts at operating expenses is a cost problem, and a loss that only appears after interest is a financing problem. Each one has a different fix, and the statement is what tells them apart.
When the statement shows a loss: read it before you react
A negative bottom line feels like a single verdict, but the two loss rows above show that it is really three different problems wearing the same minus sign, and each one has a different fix. The first step with any loss is therefore not to cut costs in general, but to find the rung where the statement turned negative — because cutting the wrong rung costs money and fixes nothing.
Take the cost-of-goods case first: revenue $250,000, cost of goods sold $200,000, operating expenses $60,000, net income −$10,000. The statement turned negative at the operating-expenses rung: gross profit was still $50,000. The arithmetic of repair is correspondingly small and specific. Cutting $10,000 from operating expenses restores exactly zero — $50,000 of gross profit minus $50,000 of running costs — before tax, and every dollar cut beyond that becomes profit. Alternatively, raising gross profit by $10,000 does the same job: a price rise, a cheaper supplier, or less waste worth $10,000 across the year. What does not fix this case is borrowing less, because there is no interest in the statement at all, or worrying about the tax rate, because there is no profit to tax. The loss is an operating-cost problem, and it is only $10,000 deep.
The revenue-fall case is deeper and different: revenue $100,000 against the same $120,000 of goods and $60,000 of running costs, ending at −$80,000. Here the statement turned negative at the very first rung — the goods alone cost more than the sales brought in — so no operating-cost cut of any plausible size repairs it: even eliminating all $60,000 of operating expenses would still leave −$20,000. The repair has to come from the top of the statement: more revenue, lower goods cost, or both, worth at least $80,000 before the business breaks even. That is a pricing, product or volume problem, and treating it as a cost-cutting exercise would shrink the business without ever closing the gap. The size of the loss matters as much as its sign: a −4.00% margin and a −80.00% margin are not two versions of “losing money”, they are a small fix and a rebuild.
There is one more discipline worth adopting for loss periods. Run the statement for the loss period and for the period before it, side by side, rung by rung, and find the rung that moved most. If revenue fell while every cost stayed still, the question is what happened to sales. If revenue held and the cost of goods sold rose, the question is suppliers, waste or pricing. If both held and operating expenses rose, the question is a specific line — rent, salaries, marketing — not “expenses” in general. And if the statement turned negative only after interest, the question is financing, not trading: the business itself still pays for its operations, and the fix may be refinancing or slower debt repayment rather than any change to how it trades. A loss read this way stops being a verdict and becomes an instruction — it tells you which line to work on first, and how big the fix has to be before the bottom line turns positive again.
Keeping the two net incomes apart
The phrase net income causes trouble precisely because it is used for two different calculations. On a pay stub, net income means take-home pay after taxes and deductions. On a company income statement, it means profit after every expense. A self-employed person meets both: their business net income is the profit of the business, and their personal net income is what remains after personal tax and deductions on that profit, which is a smaller number again. Mixing the two overstates personal spending power by the tax that has not yet been paid.
When comparing figures, always ask which net is meant. A job offer quoted as net pay and a business described as earning net income are not comparable numbers, and a freelancer who treats business profit as take-home pay will be short at tax time.
Net margin: the ratio that judges a business
Net margin, net income divided by revenue, lets businesses of different sizes be compared. A business earning $72,000 on $500,000 of revenue has a 14.4% margin. A business earning $72,000 on $200,000 of revenue has a 36% margin and is, by this measure, the stronger business, even though the profit dollars are identical. Margin also shows trends: a margin falling year by year while revenue rises is the signature of discounting, cost inflation, or both, and it deserves investigation before revenue growth is celebrated.
Margins vary enormously by industry, so the comparison set matters. Compare a business with its own industry peers and its own history, never with an absolute good margin number imported from another sector.
Freelancers: net income after tax, not before
A freelancer invoice total is gross revenue, not income. Business expenses come off first, giving business net income, and then income tax and self-employment tax come off, giving personal net income. A common budgeting rule is to set aside roughly a quarter to a third of each invoice for tax, adjusted to your actual rate, in a separate account, so tax time never surprises. The exact share depends on income, deductions, and jurisdiction, and the calculator on this site helps with the pay side; the tax side deserves its own calculation.
Frequently asked questions
What is net income for a business?
Net income is what a business has left after every cost of doing business is subtracted from its revenue: the cost of goods sold, operating expenses, interest and income tax. It is the bottom line of the income statement — the profit a business actually earned over a period, or its loss when the answer is negative.
How do you calculate net income?
Start with total revenue and subtract step by step: revenue minus cost of goods sold gives gross profit; gross profit minus operating expenses gives operating income; subtract interest to get profit before tax; then subtract income tax. For example, revenue of $250,000 with $120,000 of COGS, $60,000 of operating expenses and a 21% tax rate gives operating income of $70,000, tax of $14,700 and net income of $55,300 — a net profit margin of 22.12%.
What is the difference between net income and take-home pay?
They answer different questions for different people. Business net income is a company’s profit after its costs and taxes, and it belongs to the business. Take-home pay is what an employee keeps from a paycheck after income tax, payroll taxes and deductions. If you earn a salary, the number you want is take-home pay; if you run a business, net income is your bottom line — and what you personally take out of a business is a separate figure again.
What is a good net profit margin?
It depends heavily on the industry. Grocery stores and restaurants often run on net margins of 1 to 5 percent, many service businesses reach 15 to 25 percent, and software companies can go higher still. A margin is really only good or bad next to businesses like yours and next to your own past results — which is why this calculator shows the margin, not just the dollar figure.
Can net income be negative?
Yes. When the cost of goods sold and expenses add up to more than revenue, the result is a net loss, and this calculator shows it as a negative net income with a negative margin rather than an error. A young business can lose money on paper for months while it grows; the number to watch is whether the loss is shrinking as revenue rises.
Does the owner get to keep all of a business’s net income?
Not automatically. Net income is profit on paper, not cash in a drawer: some of it may already be spoken for by loan repayments, new equipment or stock, and non-cash costs like depreciation can make profit and cash tell different stories. What an owner personally receives — salary, dividends or draws — is decided separately, and each is taxed differently depending on how the business is set up.
What is a good net profit margin for a small business?
There is no single good number, because different kinds of business carry structurally different cost ladders. A labour-based business with little cost of goods sold will naturally show a higher margin than a business reselling physical stock. Judge your margin against your own past statements and against businesses genuinely like yours, and watch which rung moved when it changes: a falling gross margin points at pricing or supplier cost, a falling operating margin at running costs, and a falling net margin with a steady operating margin at financing or tax. The default statement on this page, at 22.12%, is one example, not a target.
Why is my net income negative when my gross profit is positive?
Because gross profit only clears the first hurdle. In the variation worked above, raising the cost of goods sold to $200,000 still leaves a gross profit of $50,000 — the goods sell for more than they cost — but the $60,000 of operating expenses then pushes operating income to −$10,000, and net income follows at −$10,000. A healthy gross profit with a negative bottom line means the running costs, not the pricing, are what need attention.
Does this calculator charge tax when the business makes a loss?
No. Tax here is a percentage of profit before tax, so when the period makes no profit there is nothing to tax: in both loss variations above, net income equals operating income exactly, with no tax line at all. Real tax systems may let a loss be carried forward against future profits, depending on the business structure, but this calculator does not model carryforwards, credits or refunds — it shows the statement for the period you entered.
What is the difference between net income and cash in the bank?
Net income measures what was earned in the period; the bank balance measures what has arrived. Customers who have not paid yet still count as revenue, stock counts as a cost only when it is sold, and loan principal repayments never appear on the income statement at all — so a profitable business can still be short of cash, and a loss-making period can still see cash rise as old invoices are collected. If the two numbers disagree, the gap is usually in receivables, stock, or loan repayments, not in the arithmetic of the statement.
Is business net income the same as take-home pay?
No. Business net income is profit after business expenses. Take-home pay is what remains after personal tax and deductions on top of that, a smaller number for a self-employed person.
What is net margin?
Net income divided by revenue, expressed as a percentage. It lets businesses of different sizes be compared and shows whether profitability is rising or falling as revenue changes.
How much should a freelancer set aside for tax?
Roughly a quarter to a third of each invoice as a starting rule, adjusted to your actual tax rate and deductions, kept in a separate account so tax time never surprises.
