How this calculator works
Enter a pre-tax price and a tax rate.
Formula
Tax = price before tax × tax rate ÷ 100.
Before you use the result
Calculator outputs are estimates based on the numbers you provide. Replace the examples with measurements, costs, rates, or product information appropriate to your situation.
Keep in mind
Taxability, rates, and rounding vary by location. This tool does not find your local rate.
