How do I back out the sales tax from a total price I already paid?

Use the extract mode in this calculator. Enter the total you paid and the applicable rate, and the tool divides the total by (1 + rate) to get the pre-tax price, then subtracts to find the tax portion. For example, a $107 total at 7% tax contains $100 of pre-tax price and $7 of sales tax.
