How sales tax is calculated
Tax = price × rate. A $100 purchase at 7.25% carries $7.25 in tax, for a total of $107.25. To go backwards, divide the total by 1 plus the rate: $107.25 / 1.0725 = $100.
Finding your rate
There is no national sales tax in the United States. Each state sets its own rate, and counties and cities often add their own on top, so the rate can differ between neighboring ZIP codes. Enter the combined state and local rate for where the purchase is made. Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax.
