Net Profit Calculator
Estimate the profit or loss left after the costs you choose to include have been subtracted from revenue, together with the resulting net margin.
How to use this calculator
- Enter revenue and the total included costs for one consistent reporting period.
- Review the worked example for net profit calculator and compare the inputs with your own units.
- Change one assumption at a time and recalculate if you need a second scenario.
Profit and margin
Net profit estimate = revenue − included costs; net margin = net profit ÷ revenue × 100.
- This simple result depends on the cost total supplied and does not perform accounting recognition, tax classification or cash-flow reconciliation.
- The result is calculated from the values entered; the page does not independently verify assumptions, data quality or real-world suitability.
Worked examples
Monthly operating summary
Revenue of 12,500 and included costs of 9,100 produce a positive remainder.
12,500 − 9,100 = 3,400; 3,400 ÷ 12,500 × 100 = 27.2%
Estimated net profit is 3,400, with a 27.2% net margin under the entered assumptions.
Understanding the result
A margin percentage helps compare periods of different sizes, if cost definitions remain consistent.
If costs are incomplete or omit taxes, depreciation, financing or other items relevant to your accounts, the result may differ from reported profit.
Important notes
Document which cost categories you included before sharing or comparing the number.
