What is a Sales Tax Calculator?

A sales tax calculator is a tool that helps you calculate the sales tax on purchases and determine the total cost. This sales tax calculator can work in two modes: calculate the total price from a pre-tax amount, or find the pre-tax price from a total.

Our sales tax calculator includes current state sales tax rates for all 50 states, making it easy to calculate accurate sales tax for any purchase. The sales tax calculator automatically computes both the tax amount and the final total.

How Sales Tax Works

Sales tax is a consumption tax imposed by state and local governments on the sale of goods and services. The tax is calculated as a percentage of the purchase price and added to the total amount you pay.

Sales tax rates vary by state, and many localities add additional taxes. For example, California has a base state rate of 7.25%, but some areas have total rates exceeding 10% when local taxes are included.

States With No Sales Tax

Five U.S. states have no state-level sales tax:

  • Alaska - No state sales tax (local taxes may apply)
  • Delaware - No sales tax
  • Montana - No state sales tax (some resort areas have local tax)
  • New Hampshire - No sales tax
  • Oregon - No sales tax

Using the Sales Tax Calculator

Our sales tax calculator offers two calculation modes:

Calculate Total: Enter the pre-tax price and tax rate to find the total cost including tax. Perfect for shopping or budgeting.
Find Pre-Tax Price: Enter the total price and tax rate to determine the original pre-tax amount. Useful for accounting and price analysis.

Select your state from the dropdown to automatically use the correct state sales tax rate, or enter a custom rate if you know your specific local rate.
