How to use it: Sales Tax Calculator
In the US, sales tax is added at the register, so the shelf price is not what you pay. This calculator adds the tax to any price, or works backwards from a receipt total to the pre-tax price and the tax that was charged.
One-tap rates cover common combined state and local rates: 4%, 5%, 6%, 6.25%, 7%, 7.25%, 8%, 8.875% (New York City) and 9.5%, and you can type the exact rate for your city or county.
How to use it
- Choose Add sales tax (shelf price) or Remove sales tax (receipt total).
- Enter the price and quantity.
- Tap your rate or type the exact combined state and local rate.
- Read the tax and total, and copy the breakdown.
How it is calculated
Tax = price × rate ÷ 100, total = price + tax. From a total: pre-tax price = total ÷ (1 + rate/100).
Worked example
A $249.99 TV in a city with 8.875% sales tax costs $22.19 in tax, $272.18 in total. A receipt for $53.75 at 7.5% means a pre-tax price of $50.00 and $3.75 of tax. Five $12 items at 6.25% cost $63.75.
Who uses it

- Small sellers quoting prices with tax
