About this calculator
What's a typical US sales tax rate?
Combined rates usually range from 0% (in states like Oregon and New Hampshire) to over 10% in some local jurisdictions. State portions are commonly 4–7%.
Are groceries and clothing taxed?
It depends on the state. Many states exempt groceries, prescription drugs, and sometimes clothing. Check your state's department of revenue.
Does this work for online purchases?
Yes — since the South Dakota v. Wayfair (2018) decision, most online retailers collect sales tax based on the buyer's location.
