Frequently asked questions

How do I find the price before tax?

Divide the price with tax by 1 plus the rate: 108 with 8% tax is 108 / 1.08 = 100 before tax.

How do I add sales tax to a price?

Multiply by 1 plus the rate: 50 with 7% tax is 50 × 1.07 = 53.50.

Why is there no single US sales tax rate?

Sales tax is set by states, counties and cities, so the rate depends on where you buy. Five states have no statewide sales tax.
