Calculate sales tax
Enter an amount and a tax rate above to see the tax owed and the total price including tax. It is useful for adding sales tax or VAT to a price, checking a receipt, or budgeting for a purchase before you reach the till. The calculation runs in your browser, so nothing is uploaded.
How it is worked out
The tax is the amount multiplied by the rate percent, and the total is the original amount plus that tax.

Multiply the amount by the tax rate percentage to get the tax, then add it to the original amount for the total.
