Gross Profit Calculator
Calculate gross profit and gross margin percentage from revenue and cost of goods sold, then compare direct profitability across products or periods.
Gross profit
Formula
Gross Profit = Revenue - Cost of Goods Sold
Gross Margin = Gross Profit / Revenue * 100 How the formula works
Gross profit subtracts cost of goods sold from revenue. Gross margin converts that result into a percentage of revenue so different products, months, or categories can be compared more easily.
The key is consistency. If one calculation includes fulfillment in COGS and another excludes it, the margins are not directly comparable.
Complete example
A business earns $50,000 in revenue from a product category. The cost of goods sold for that category is $32,000.
- Revenue: $50,000
- Cost of goods sold: $32,000
- Gross profit: $50,000 - $32,000 = $18,000
- Gross margin: $18,000 / $50,000 * 100 = 36%
This means $0.36 of each revenue dollar remains after COGS, before operating expenses and other costs.
For the difference between gross and net numbers, read gross profit vs net profit.
When to use this calculator
- Measure direct profitability from revenue and COGS.
- Compare product categories or sales periods using the same COGS definition.
- Check whether rising product costs are reducing gross margin.
- Prepare a quick gross profit estimate before deeper net profit analysis.
How to interpret the results
Gross profit is the dollar amount left after COGS. Gross margin is the percentage of revenue left after COGS. Higher gross margin usually means more room to cover overhead, marketing, payroll, taxes, and profit.
If gross profit is negative, the direct cost of goods sold is higher than revenue. That usually requires a price increase, cost reduction, product mix change, or review of the COGS inputs.
Common mistakes
- Putting all operating expenses into cost of goods sold without a clear accounting reason.
- Comparing gross margin between businesses that define COGS differently.
- Using gross profit as if it were final take-home profit.
- Leaving out direct fulfillment or packaging costs when those costs belong in COGS.
- Comparing one product's gross margin to another after using different time periods or cost definitions.

FAQ
What is gross profit?
Gross profit is revenue minus cost of goods sold. It shows how much money remains after direct production or delivery costs.
How do you calculate gross margin?
Divide gross profit by revenue, then multiply by 100.
Is gross profit the same as net profit?
No. Gross profit usually excludes operating expenses, taxes, interest, and other costs.

Yes. If cost of goods sold is higher than revenue, gross profit is negative.
What should be included in COGS?
COGS usually includes direct costs tied to producing or delivering what was sold, such as materials, product cost, direct labor, packaging, or fulfillment costs when appropriate.
Should operating expenses be included?
Usually no. Rent, admin payroll, marketing, software, taxes, and interest are normally considered after gross profit unless your accounting method classifies a cost differently.
Why is gross margin useful?
