About This Calculator
This calculator computes the sales tax amount and final total price for a purchase, given the pre-tax price and your local combined sales tax rate (state + county + city, where applicable).
How This Is Calculated
Tax = Price × Sales Tax Rate
A $100 purchase at a 7.25% sales tax rate costs $107.25 total, with $7.25 in tax.
Assumptions
- Sales tax rates vary significantly by state, county, and city — some states have no sales tax at all.
- Some items (like groceries or clothing in certain states) may be exempt or taxed at a different rate.
