A LITTLE KNOW-HOW

About this tool

Use one percentage rate to calculate tax on an amount, or recover the pre-tax amount from a total that already includes tax. Enter the rate applicable to your transaction. All amounts remain in the same currency; this tool performs arithmetic and does not decide tax registration, exemptions, jurisdiction or the correct rate.

How to use it

  1. 1

    Choose whether your starting amount excludes tax or already includes it.

  2. 2

    Enter the amount and the applicable tax percentage, using 10 for 10%.

  3. 3

    Review the pre-tax amount, tax and total in the currency you entered.

Questions, answered

What formulas add and extract tax?

For rate r entered as a percent, added tax = pre-tax amount × r / 100. When tax is already included, pre-tax amount = total / (1 + r / 100), and tax = total − pre-tax amount. At 10%, a total of 1,100 contains 100 of tax; subtracting 10% of 1,100 would be incorrect.

Does the result determine which tax I legally owe?

No. Supply the correct rate for your jurisdiction and transaction. This calculator handles one percentage rate between 0% and 100%, with up to four decimal places. Monetary inputs support two decimal places, and the result rounds to the nearest hundredth. Local invoice rounding or multiple taxes can produce different amounts.
