Sales tax is calculated by multiplying the pre-tax price by the tax rate, expressed as a decimal. For example, a $40 item with a 7% tax rate has a tax of $2.80 and a total of $42.80. Enter your price and rate below to get the result instantly.
Enter the pre-tax price of the item in the first field and the applicable tax rate in the second field. The tax amount and the final total update as you type.
If you know the total (tax included) and need the pre-tax price, divide the total by (1 plus the rate as a decimal). For example, a $53.50 total with 7% tax has a pre-tax price of $53.50 / 1.07 = $50.00. A reverse calculator mode may be added in a future update.
Rates shown are the state base rate only. Counties and cities often add to this. Verify the exact rate with your state revenue agency or point-of-sale system before relying on it for business purposes.

| Pre-tax price | Tax rate | Tax amount | Total |
|---|---|---|---|
| $10.00 | 5% | $0.50 | $10.50 |
| $49.99 | 7.25% | $3.62 | $53.61 |
| $200.00 | 8.875% | $17.75 | $217.75 |
| $1,500.00 | 6.5% | $97.50 | $1,597.50 |
Multiply the pre-tax price by the tax rate divided by 100. For example, $80 at 8% tax is $80 x 0.08 = $6.40 in tax, giving a total of $86.40.
State base rates range from 0% (Oregon, Montana, Delaware, and a few others) to over 7% (California, Tennessee). Most states also allow counties and cities to add local rates on top, so the rate at any given store can be higher than the state base rate.
Divide the total price by (1 plus the tax rate as a decimal). A $107 total with a 7% tax rate has a pre-tax price of $107 / 1.07 = $100.
