US sales tax calculator and reverse sales tax
In the United States, sales tax is not the same everywhere – it differs by state and sometimes even by city or county. This sales tax calculator lets you enter any tax rate and also provides quick presets for popular locations like California sales tax, New York City sales tax and sales tax Texas. You can immediately see the tax amount and the final price.
Many people search for a simple sale tax calculator or calculator for sales tax when shopping, freelancing or doing bookkeeping. With this tool you can calculate forward (from price before tax to total) and use the reverse sales tax calculator (from total price back to pre-tax price), which is helpful when you only know the final amount on a receipt.
How do I calculate sales tax?
Calculating sales tax manually is straightforward: multiply the price before tax by the
sales tax rate. For example, if the rate is 8.875% in New York City,
a pre-tax price of $100.00 gives $100.00 × 0.08875 = $8.88 sales tax and a total of
$108.88. This calculator does that automatically and formats the numbers for you,
so you can focus on calculating sales tax instead of formulas.
Sales tax differs per state (and city)
Because sales tax US is not a single national rate, this calculator lets you:
- Start with a preset for California, New York City or Texas.
- Override the rate with your own percentage if your local area is different.
- Switch between forward and reverse sales tax by editing either field.
This is useful for online sellers, small businesses, and anyone who needs a fast sales tax US calculator without installing software.
