About This Calculator
The Sales Tax Calculator helps you determine the sales tax amount and total price for any purchase. Enter the item price and tax rate to instantly calculate how much tax you'll pay and the final total.

Formula & Calculation Method
Sales Tax Formula:
Sales Tax Amount = Price × (Tax Rate / 100)
Total Price = Price + Sales Tax Amount
Or: Total Price = Price × (1 + Tax Rate / 100)
Sales tax is calculated as a percentage of the purchase price. The tax amount is added to the original price to get the total you'll pay at checkout.
