Sales Tax Calculator
Enter a price and a tax rate to add sales tax or VAT and see the tax amount and final total — or switch to remove tax from a gross total to find the original pre-tax price. It works with any rate or currency and runs entirely in your browser: free, instant, and no sign-up.
Frequently asked questions
Multiply the price by the tax rate divided by 100 to get the tax amount, then add it to the price for the total. For example, 8% tax on $50 is $50 × 0.08 = $4, for a $54 total. Enter your figures above and the calculator does it instantly.
Divide the gross total by 1 plus the rate as a decimal. For 20% VAT, divide the total by 1.20 to get the pre-tax price, and the difference is the tax. Switch this tool to its remove-tax mode to do it automatically.
