# Sales Tax Calculator

This online sales tax calculator will help you calculate sales tax value and also the price of the product inclusive of sales tax as well as the price of the product exclusive of sales tax. This calculator works exactly the same for VAT or GST calculations.

#### Sales Tax/ VAT Calculation Formula

If S is the selling price without sales tax, T is the sales tax rate in percentage, T\$ is the sales tax in dollar amount, and Stax is the selling price including the sales tax, then
T\$ = S*T/100
Stax = S+T\$
Stax = S*(1+T/100)

In the calculator shown below, the first field is for Selling price without tax, the second field is for Tax rate (%) and the third field is for Selling price including tax.

Find tax-inclusive price, Stax: Enter selling price & tax rate
