Add a Tax Rate Calculator
Tax amount equals taxable subtotal multiplied by the entered rate divided by 100. A subtotal of 250 at an assumed 8% rate gives tax of 20 and a total of 270.
Formula & method
Tax = taxable subtotal × entered rate ÷ 100; total = subtotal + tax.Worked example
| Input | Value |
|---|---|
| Taxable subtotal | 250 ¤ |
| User-entered tax rate | 8 % |
| Result | Value |
|---|---|
| Calculated tax amount | 20 ¤ |
| Subtotal plus tax | 270 ¤ |

The first input changes while the other example inputs stay fixed. These are arithmetic scenarios, not forecasts.
| Compare scenarios | Taxable subtotal ¤ | Calculated tax amount | Subtotal plus tax |

| −20% | 200 | 16 ¤ | 216 ¤ |
| Example | 250 | 20 ¤ | 270 ¤ |
| +20% | 300 | 24 ¤ | 324 ¤ |
Assumptions & limits
The sample 8% is an arbitrary arithmetic input, not a tax rate for any place or date. This does not determine taxability, exemptions, compound taxes, local rounding, filing duties or the rate that applies to you.
Displayed results are rounded. Calculations use unrounded JavaScript numbers; small floating-point differences are possible.
