What is the Gross Margin Calculator?
Calculate gross profit and gross margin from revenue and COGS. To use the Gross Margin Calculator, enter revenue, cogs; it returns gross margin, gross profit, markup on cogs, and shows them instantly as you type.
From revenue to cash flow
Work down the income statement: gross margin, operating margin, EBITDA and net margin. Then confirm profit is real cash with the free cash flow calculator and the accrual ratio.
Efficiency ratios show how fast money turns. The Cash Conversion Cycle Calculator combines DSO, DIO and DPO into one number of days.
- Costs. Marginal cost, average variable cost and the optimal price tools support pricing decisions.
- Elasticity. Price, cross-price and income elasticity show how demand reacts.
How to use the Gross Margin Calculator
- Enter your numbers. The inputs are Revenue ($), COGS ($). Use numbers from the same accounting period so the ratios are comparable. Fields marked optional can stay at zero.
- Read the result. The highlighted box gives the Gross margin, and the cards below show Gross profit, Markup on COGS. Tables and charts break it down further.
- Test other scenarios. Results update as you type. Change one value at a time to see what drives the answer, and press Reset to go back to the defaults.
Formula and how it works
Example with real numbers
Here is the Gross Margin Calculator using the default values shown in the calculator above:
Inputs
| Revenue ($) | 750,000 |
|---|---|
| COGS ($) | 450,000 |
Results
| Gross margin | 40% |
|---|---|
| Gross profit | $300,000.00 |
| Markup on COGS | 66.67% |
With these inputs the calculator returns Gross margin: 40%. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Revenue ($) from 750,000 to 900,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Gross margin | 40% | 50% | +25% |
| Gross profit | $300,000.00 | $450,000.00 | +50% |
| Markup on COGS | 66.67% | 100% | +50% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.

Frequently asked questions
Why does gross margin matter?
It shows how much each sale contributes before overhead.
Why use average balances?
Ratios that compare a flow (sales, income) with a balance (assets, equity) are fairer when the balance is averaged over the period.
What is the cash conversion cycle?
It is DIO plus DSO minus DPO: the days between paying suppliers and collecting from customers.
Are the results guaranteed?
No. Results depend entirely on the numbers you enter and the formulas shown on this page. Please do not make financial decisions based on them alone; confirm important figures with a licensed professional.
