Sales Tax Formulas
US sales tax is added at the register as a percentage of the price. This calculator works it out in all three directions: the tax on a price, the price hidden inside a total, and the rate you were charged.
Tax = Price × Rate ÷ 100
Total = Price × (1 + Rate ÷ 100)
Price before tax = Total ÷ (1 + Rate ÷ 100)
Rate = (Total − Price) ÷ Price × 100
Example: a $250 item at a combined 7.5% rate has $18.75 of tax, for a total of $268.75.

Frequently Asked Questions
How do I calculate sales tax?
Multiply the price by the rate and divide by 100. For a $100 item at 8.25%, the tax is $100 × 8.25 ÷ 100 = $8.25, so you pay $108.25. The same works for any currency.
How do I find the price before tax from a total?
Divide the total by 1 plus the rate as a decimal. A receipt total of $108.25 at 8.25% tax means $108.25 ÷ 1.0825 = $100 before tax, and $8.25 of tax. Do not just subtract 8.25% of the total; that gives $99.32, which is wrong.
How do I work out what tax rate I was charged?
Subtract the price from the total, divide by the price and multiply by 100. Paying $54.13 for a $50 item means ($54.13 − $50) ÷ $50 × 100 = 8.26%.
Why is my local rate higher than the state rate?
In most states, counties, cities and special districts add their own sales tax on top of the state rate, so the rate at the register can be several points higher. Enter that extra as the local rate; your state's revenue department publishes rates by address.
Which states have no sales tax?
Alaska, Delaware, Montana, New Hampshire and Oregon have no statewide sales tax. Some Alaska and Montana towns still charge a local sales tax, and some states tax specific items such as meals or lodging.
Is VAT the same as sales tax?
Both are consumption taxes, but VAT, used in the UK, the EU and most other countries, is usually already included in the shelf price, while US sales tax is added at the register. Use Remove tax to find the price before VAT, for example £120 at 20% VAT is £100 plus £20 VAT.
Are the state rates up to date?
The built-in rates are state base rates from the Tax Foundation as of January 1, 2025. States change rates occasionally and many items, such as groceries or clothing, are taxed at lower rates or exempt, so check your state's revenue department for official figures.
