How to Reverse Calculate Sales Tax?

Calculating sales tax is a common task, but sometimes you may find yourself needing to reverse calculate it. Perhaps you want to find out the pre-tax price of an item or determine the tax rate that was applied. Whatever the reason, reverse calculating sales tax can be done with a simple formula.

To reverse calculate sales tax, you can use the following formula:
Pre-tax price = Post-tax price / (1 + tax rate)

For example, if you bought an item for $110 including sales tax at a rate of 10%, to find out the pre-tax price:
Pre-tax price = $110 / (1 + 0.10) = $100

This formula allows you to quickly and accurately determine the pre-tax price of an item based on the post-tax price and the tax rate applied. So the next time you need to reverse calculate sales tax, just plug in the numbers and use this formula to get the answer.
