This calculator adds or removes US sales tax at any state or local rate, showing the tax amount and the total or pre-tax price. Updated June 2026.
Sales Tax & Total Cost (2026, by State)
How It Works
This tool multiplies your purchase amount by the sales tax rate to find the tax, then adds it to the amount for the total cost. The built-in rates are approximate 2026 average combined state plus local sales tax rates. Pick a state, or choose "Other / enter rate" and type a precise percentage for your city or county. Remember that five states — Oregon, Montana, New Hampshire, Delaware and Alaska (no state rate) — have no statewide sales tax.
