TopToolAIUSA Sales Tax Calculator
Calculate US sales tax on a purchase amount at any rate — since US sales tax varies by state and locality, enter your local rate for an accurate total. A $200 purchase taxed at a typical 8% combined state-and-local rate adds $16 in tax, for a total of $216 — rates range from 0% in states like Oregon to over 9% in parts of Louisiana, so entering the correct local rate matters.
