How to use the Profit Margin Calculator
Enter revenue and cost. The calculator shows profit and profit margin as a percentage of revenue. Enter values from the same sale, product, price, or accounting scenario so percentages and totals are compared on a consistent basis.
What this calculator does
Calculate profit, margin percentage, and markup from revenue and cost. It is intended to make the calculation transparent and repeatable: you provide the known values, the calculator applies the relevant relationship, and the result is shown with the units or labels used by the tool.
When this tool is useful
Use the Profit Margin Calculator when you need a quick, repeatable check and already have the inputs requested by the page. It is useful for comparing scenarios, checking hand calculations, planning a task, or understanding how changing one input affects the result.
How the calculation works
Profit is revenue minus cost. Margin is profit ÷ revenue × 100, while markup compares profit with cost.
Practical example
For a practical check, enter a small set of values you can verify independently, then compare the calculator’s result with the relationship described above before using it for a larger profit margin problem.
Things to keep in mind
- Taxes, fees, discounts, shipping, overhead, and accounting treatment can change real-world profitability or pricing.
- Businesses and jurisdictions may use different definitions, rounding conventions, or reporting rules.
- Use the result as a planning check and confirm final figures against invoices, accounting records, or applicable rules.
