What Is a Sales Tax Calculator?

A sales tax calculator adds or extracts sales tax from a price so you can see the pre-tax amount, the tax amount, and the total.

How it works: Tax amount = price x (rate / 100). Total price = price + tax amount. The calculator on this page runs entirely in your browser, so results are instant and nothing is uploaded or stored.
