About this calculator

US sales tax is added at the register: multiply the price by your combined rate and add it on. At 7%, a $100 purchase costs $107.

Unlike VAT or GST countries, the US has no national rate — sales tax is set by states, counties and cities, and the combined rate is what you actually pay. State base rates range from 0% (Delaware, Montana, New Hampshire, Oregon; Alaska has no state rate but allows local ones) to over 7%, and local additions push combined rates in some cities past 10%. Check your local rate and enter the combined figure.

What's taxable also varies: many states exempt groceries and prescription drugs, and some run tax-free holidays. Online purchases are generally taxed at the delivery address's rate.
