Gross ↔ Net Profit Converter — Full P&L Breakdown

Convert between gross profit and net profit. See EBITDA, EBIT and EBT at each step of the profit waterfall.
Profit Waterfall Explained
Reading the Waterfall Like an Analyst
Each line in the waterfall answers a different question about the same business, and confusing them is the most common mistake in small-business finance.
Gross profit asks: does the thing you sell cost less than you sell it for? It is a question about the product, not the company. If gross profit is thin, no amount of cost discipline further down will save the business — the unit economics themselves are wrong.
EBITDA asks: does the operation work, ignoring how it was financed and how the assets are being written off? It is the cleanest comparison between two businesses with different debt loads and different depreciation policies, which is why acquirers reach for it first.
EBIT puts depreciation back in. For an asset-heavy business — manufacturing, logistics, hospitality — that difference is the whole story, and EBITDA flatters it badly.
EBT subtracts finance cost. Two identical operations can show the same EBIT and wildly different EBT purely because one is levered and the other is not.
Net profit is what is left for the owners. It is the only line that eventually becomes dividend or retained earnings, and the only one that ties to the balance sheet.
What Actually Belongs in COGS
The converter is only as accurate as the split you feed it, and the COGS boundary is where most first drafts go wrong.
- Goes in COGS: raw material, direct labour on the production floor, freight inward, factory power and consumables, packaging that ships with the product, and for a services business the salaries of people whose time is billed to clients.
- Stays in operating expenses: rent for the office rather than the factory, sales and marketing, administrative salaries, professional fees, software subscriptions, and the founder’s own salary unless the founder is delivering billable work.
- Neither: interest on borrowings is a finance cost, not an operating expense. Loan principal repayment is not an expense at all — it never touches the P&L. Capital purchases are not expensed either; they arrive later as depreciation.
A useful test: if you sold one more unit tomorrow, would the cost move? If yes, it is close to COGS. If the cost would be identical whether you sold one unit or a thousand, it is an operating expense.
Why the Two Margins Move Independently
Gross margin and net margin tell you where a problem lives. Falling gross margin with steady operating costs points at pricing, input costs or product mix. Healthy gross margin collapsing into thin net margin points at overheads, interest, or both — the product is fine and the company is not.
The waterfall makes this visible. Run your own numbers through the converter twice, a year apart, and read which gap widened. That single comparison is more diagnostic than any single margin figure taken on its own.
A Note on the Tax Rate Input
The tax field applies a flat effective rate to earnings before tax, which is a modelling simplification rather than a tax computation. Real corporate tax in India depends on the entity type, whether a concessional regime has been opted into, the treatment of depreciation and other allowances, minimum alternate tax where applicable, and surcharge and cess on top of the headline rate. Book profit and taxable profit are rarely the same number.
Use this field to sketch a scenario, and take the actual rate from your last filed return or your accountant. Do not treat the output as a tax liability.
Where to Go Next
Once the waterfall is right, the profit margin calculator expresses each line as a percentage, the break-even calculator tells you the volume at which gross profit finally covers fixed costs, and the working capital position explains why a profitable business can still run out of cash. For the underlying accounting, the free income statement lesson and the guide to reading a balance sheet cover the statements this converter summarises.
Frequently Asked Questions
EBITDA strips out financing decisions (interest) and accounting choices (depreciation method), making it useful for comparing operational profitability across companies and capital structures. Venture capitalists and PE firms often value startups at a multiple of EBITDA (e.g., 8–12× EBITDA). However, EBITDA can be misleading — high EBITDA with heavy capex requirements may mean little free cash flow.
Gross margin focuses only on the cost of producing goods/services (COGS). Net margin reflects the full picture after all costs, interest, and taxes. A high gross margin with low net margin suggests excessive operating costs or high debt burden. Ideally both should be tracked together.
It does not, and that is the limitation of any P&L view. Profit is measured when a sale is recognised, not when the money arrives. A business with long receivable cycles, rising inventory or heavy loan principal repayment can post healthy net profit and still be unable to pay salaries. Read the profit waterfall alongside a cash flow view, never instead of one.
Keep it separate. That is precisely what distinguishes EBITDA from EBIT. If you fold depreciation into operating expenses the converter will still compute, but you lose the ability to compare your operation against a business with a different asset base or a different depreciation policy.
Not on its own. Software businesses routinely show very high gross margins and negative net margins because customer acquisition sits below the gross profit line. A distributor may show a thin gross margin and a perfectly healthy net margin because it carries almost no overhead. The two figures are only meaningful together, and only against the same business over time or a genuine peer.
