| 50 | 7.25% | 3.63 | 53.63 |
| 200 | 10% | 20 | 220 |
Removing tax: a 108 total at 8% tax is 108 / 1.08 = 100 before tax, so the tax was 8.

FAQ
How do you add sales tax to a price?
Multiply the price by the tax rate and add it. For 8% on 100: 100 x 0.08 = 8, so the total
is 108.
How do you remove sales tax from a total?
Divide the total by 1 + tax rate. For an 8% tax on a 108 total: 108 / 1.08 = 100 before
tax, so the tax was 8.
Is sales tax the same everywhere?
No. Rates vary by country, state, and city, and some items are taxed differently. Enter your local rate.
What is the formula for sales tax?
Tax is price x rate, and the total is price x (1 + rate). To reverse it, the price before
tax is total / (1 + rate).
