How to Use This Sales Tax Calculator
This tool supports two common tax calculation scenarios:
- Add Tax to a Price — Enter the pre-tax price of an item and the sales tax rate. The calculator shows how much tax will be added, and your final total.
- Find Pre-Tax Price from a Total — If you have a receipt with a tax-included total and need to know the original price before tax and the tax amount paid, switch to this mode.
Tax rates vary by state, county, and city. Enter the combined rate that applies in your area. Need to work backwards from a total? Try our Reverse Sales Tax Calculator for a dedicated experience.
