About Sales Tax Calculator
Two directions, one tool. Forward: enter a pre-tax price and your local rate to get the tax and the total at the register. Reverse: paste a tax-inclusive total from a receipt and the same rate, and it backs out the pre-tax price — handy for expense reports and price comparisons across regions.
Common uses
- Know the checkout total for an online cart shipped to your state
- Split a receipt total into base price and tax for bookkeeping
- Compare prices between areas with different tax rates
Example
Input

Limitations
- You supply the rate — the tool doesn't look up local tax rates, which vary by city and category.
