About this tool
What the Net Profit After Tax Calculator does
Net profit after tax is what is left from revenue once cost of goods, operating expenses, interest and tax are paid. This calculator walks down the income statement and shows the margin at each level, so you can see where profit is being lost.
Formula
- Gross profit = revenue − cost of goods sold
- EBIT = gross profit − operating expenses
- Profit before tax = EBIT − interest
- Net profit = profit before tax − tax
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Revenue | $800,000 |
| Cost of goods sold | $420,000 |
| Operating expenses | $220,000 |
| Interest expense | $15,000 |
| Tax rate | 25% |
| Result | Value |
|---|---|
| Net profit after tax | $108,750 |
| Net margin | 13.6% |
| Gross profit | $380,000 |
| Operating profit (EBIT) | $160,000 |
| Profit before tax | $145,000 |
| Tax | $36,250 |
How to read the result
Tax is applied only when profit before tax is positive. Real tax bills depend on allowances, losses carried forward and local rules.
If gross margin is healthy but net margin is thin, look at operating expenses; if gross margin is thin, look at pricing and cost of goods.
