Sales Tax Calculator

How this sales tax calculator works

Enter the price of your item and the applicable tax rate (as a percentage). The calculator computes the tax amount and the total cost including tax. This works for US sales tax, European VAT, Australian GST, and any other percentage-based consumption tax.

The sales tax formula

Tax amount = Price × (Rate ÷ 100)

Total = Price + Tax amount
