About this tool
Sales tax = price × quantity × rate ÷ 100, and the total is the subtotal plus the tax. When the total already includes tax, the pre-tax price is the total ÷ (1 + rate ÷ 100).
Sales tax rates depend on the state, city and type of product, and some items are exempt. Enter the rate that applies to your purchase. Shops may round tax per item or per receipt, so the last cent can differ. This tool is not tax advice.

Common questions
How do I find my sales tax rate?
Check your state or local tax authority, or a recent receipt. Combined state and local rates are often between about 4% and 10% in the US.
Is this the same as VAT?
The idea is similar, but VAT is charged at each stage of production. Use the VAT Calculator if you are working with VAT.
