A sales tax calculator is an online tool that helps you calculate how much tax is added to a product or service price. Instead of doing manual percentage calculations, you can enter the price and tax rate to instantly get the tax amount and final total.
This tool also supports reverse sales tax calculation. That means if you already know the final amount including tax, you can calculate the original before-tax price and see how much tax was included in the total.
To add sales tax, the formula is: Tax Amount = Price × Tax Rate / 100
Then the final price is: Total Price = Price + Tax Amount
For reverse sales tax, the formula is: Before Tax Price = Total Price / (1 + Tax Rate / 100)
Sales tax is a percentage added to the price of certain goods or services. The buyer usually pays it at checkout, and the seller collects it according to local tax rules.
Multiply the price by the tax rate and divide by 100. For example, if the price is $100 and tax is 8%, the tax amount is $8 and the total is $108.
