About this tool
Free Profit Calculator
Use the free WebToolsEdge Profit Calculator to estimate how much money a business, product, project, or sales period earns after costs. Enter revenue, cost of goods sold, operating expenses, other costs, and an optional estimated tax rate. The calculator instantly shows gross profit, operating profit, estimated tax, net profit or loss, total costs, and several useful profitability percentages. Gross profit equals revenue minus cost of goods sold (COGS). Gross margin expresses gross profit as a percentage of revenue, while markup compares gross profit with COGS. Operating profit subtracts operating expenses and other costs from gross profit. Estimated net profit then subtracts the selected tax estimate when pre-tax operating profit is positive. Keeping these measures separate helps explain whether pricing, direct costs, overhead, or tax has the largest effect on the final result. The tool can be used for ecommerce products, retail sales, freelance projects, service businesses, marketing campaigns, monthly business reviews, and quick what-if analysis. Change revenue or any cost field to compare scenarios, test a price increase, review expense reductions, or estimate the sales needed to maintain a healthier margin. A negative net result is clearly displayed as an estimated loss. This calculator provides a planning estimate rather than formal accounts or tax advice. Real profit may include discounts, refunds, inventory adjustments, depreciation, financing costs, payroll taxes, sales taxes, extraordinary items, and jurisdiction-specific accounting rules. Use consistent figures from the same period and confirm important decisions with accurate bookkeeping records or a qualified accountant.
If a business or equipment loan is part of your monthly costs, estimate its payment with the EMI Calculator. You can also browse all Calculators for related planning tools.

Questions
Profit Calculator FAQ
How do I calculate profit?+
Subtract business costs from revenue. This calculator separates cost of goods sold, operating expenses, other costs, and estimated tax to show gross, operating, and net profit.
What is the difference between gross profit and net profit?+
Gross profit subtracts direct cost of goods sold from revenue. Net profit also accounts for operating expenses, other costs, and the estimated tax entered in the calculator.
What is profit margin?+
Profit margin expresses profit as a percentage of revenue. Gross margin uses gross profit, while net margin uses profit after the entered costs and estimated tax.
What is the difference between margin and markup?+
Margin compares profit with selling revenue. Markup compares gross profit with cost of goods sold. The percentages use different bases and are not interchangeable.
Can this calculator show a business loss?+
Yes. If total costs and estimated tax exceed revenue, the result is displayed as an estimated net loss with a negative net margin.
Should sales tax be included in revenue?+
Use figures that match your accounting method. Many businesses exclude sales tax collected on behalf of authorities from revenue, but rules vary by jurisdiction.
