How the Sales Tax Calculator works

US-style sales tax is added at the register on top of the listed price:

Sales tax = Price × Tax rate ÷ 100
Total = Price + Sales tax

For example, an item priced 49.99 with an 8.25% rate has 4.12 tax and a total of 54.11. Sales tax rates vary by state, county and city, so use the combined rate for where the purchase is made. If your prices already include tax, use the GST/VAT Calculator's remove-tax option instead.
