How to use Sales Tax Calculator

Enter a pre-tax price and a percentage rate. The tool adds tax to the price and reports the tax amount separately.

How Sales Tax Calculator calculates the result

Tax amount = pre-tax price × tax rate ÷ 100. Final price = pre-tax price + tax amount. This assumes one percentage-based, tax-exclusive rate, without exemptions or jurisdiction-specific rounding.

Example

A price of 100 with 20% tax yields 20 tax and a final price of 120.

What to know

This is a simple single-rate estimate. Tax rules, exemptions, inclusive-price regimes and rounding laws vary by location.
