Tax-Inclusive Price Split Calculator
For a total that includes one percentage tax on its base, divide the total by one plus the rate fraction. An inclusive total of 108 at an assumed 8% separates into 100 base and 8 tax.
Formula & method
Pre-tax base = inclusive total ÷ (1 + rate/100); included tax = total − base.Worked example
| Input | Value |
|---|---|
| Tax-inclusive total | 108 ¤ |
| User-entered included tax rate | 8 % |
| Result | Value |
|---|---|
| Pre-tax base | 100 ¤ |
| Included tax amount | 8 ¤ |
Compare scenarios
The first input changes while the other example inputs stay fixed. These are arithmetic scenarios, not forecasts.
| Compare scenarios | Tax-inclusive total ¤ | Pre-tax base | Included tax amount |
|---|---|---|---|
| −20% | 86.4 | 80 ¤ | 6.4 ¤ |
| Example | 108 | 100 ¤ | 8 ¤ |
| +20% | 129.6 | 120 ¤ | 9.6 ¤ |
Assumptions & limits
This assumes one tax rate calculated on the pre-tax base. It does not handle mixed-rate baskets, compound levies, exemptions or jurisdiction-specific rounding. The example rate is hypothetical and is not tax advice.
Displayed results are rounded. Calculations use unrounded JavaScript numbers; small floating-point differences are possible.

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.
Unit Price Calculator
Unit price equals total package price divided by quantity. A package costing 18 for 12 equivalent units costs 1.50 per unit.
Gross Margin Calculator
Gross margin is revenue minus included cost of goods, divided by revenue, multiplied by 100. Revenue of 1,000 and cost of 650 gives a gross profit of 350 and margin of 35%.
Markup Calculator
Markup equals selling price minus cost, divided by cost, multiplied by 100. Buying at 80 and selling at 100 gives a 25% markup, while the margin is 20%.
