How to use
- Type the price before tax, the number on the tag.
- Type the sales tax rate as a percent. 8.25 means 8.25 percent, not 0.0825.
- Press Calculate. The hero number is the amount you pay. The tax line is only the tax.
- Press Reset to clear both fields.
How it's calculated
Tax equals the price multiplied by the rate, divided by 100. The total equals the price plus that tax. There is no bracket, no exemption, and no second local rate unless you already combined those rates into the single percent you typed.
If a city rate and a state rate both apply, add those percents yourself and enter the sum. Two separate 2 percent taxes are 4 percent on this page, not a tax on a tax, unless your local rule actually stacks them that way.
Worked example
An $80 jacket at 8.25 percent tax: 80 × 0.0825 = $6.60 of tax. The amount you pay is $86.60. At a zero rate the tax line is $0 and the total matches the price.
Assumptions
The rate is whatever you enter. This page does not store state rates and it does not decide whether an item is exempt. Rounding is to the cent only in the currency display.
FAQ
Does this include a state rate for me?
No. Look up the rate on your receipt or your state revenue site and type it in.
How do I remove tax from a price that already includes it?
That is a different question. If the total is tax-inclusive, price before tax = total ÷ (1 + rate ÷ 100). This page goes the other direction: it adds tax to a pretax price.
Can the rate be zero?
Yes. A zero rate is a legal input. The tax is zero and the total equals the price.
Why is my receipt a penny different?
Receipts round each line or the whole ticket. This page computes one price times one rate.
