What Is a Sales Tax Calculator?
A Sales Tax Calculator is an online tool that helps you determine how much sales tax will be added to the price of a product or service. It also calculates the final amount after the tax is added.
Instead of calculating the percentage manually, enter the original price and tax rate and the calculator will instantly show the sales tax and total price.
How to Calculate Sales Tax
To calculate sales tax, multiply the original price by the sales tax rate divided by 100.
For example, if an item costs $100 and the sales tax rate is 8%, the sales tax is $8 and the final price including tax is $108.
Sales Tax Formula
Sales Tax = Price × Tax Rate ÷ 100
Total Price = Price + Sales Tax
Example
Suppose a product costs $250 and the sales tax rate is 7.5%.
Sales Tax = $250 × 7.5 ÷ 100 = $18.75
Total Price = $250 + $18.75 = $268.75
