• Sales tax: This is the sales tax amount. For example, if an item costs $100, and the sales tax rate is 8%, then the sale tax is$8.
• Sales tax rate: This is the sales tax rate, which is a percentage to the pre-tax amount.
• Final price: The final price is the after-tax amount and includes the sales tax.

## How do you find the original price before tax?

### Using sales tax rate (percent)

If you know the final price and the sales tax rate, the formula for calculating the pre-tax price is:

Pre-tax price = Final price ÷ (1 + Sales tax rate)

For example, if the final price of an item is $25 and the sales tax rate is 9%, then the pre-tax price is: Pre-tax price = Final price ÷ (1 + Sales tax rate) =$25 ÷ (1 + 9%) = $23.15 ### Using sales tax amount If you know the final price and the sales tax amount in dollars, then the formula for calculating the pre-tax price is: Pre-tax price = Final price − Sales tax amount For example, if the final price of an item is$25 and the sales tax amount is $8, then the pre-tax price is: Pre-tax price = Final price − Sales tax amount =$25 − $2 =$13

To calculate the sales tax rate, you would use the following equation:

Sales tax rate = Sales tax amount ÷ Pre-tax price

In the above example, the sales tax rate would be $2 ÷$16 = 8.7%.
