Sales Tax Calculator

Add sales tax to a net price, or reverse-calculate from a gross total.

Net: $0.00
Tax: $0.00
Gross: $0.00

How It Works

In "add" mode, tax = amount × rate and gross = amount + tax. In "remove" mode, net = amount ÷ (1 + rate) so you can work backwards from a tax-inclusive total to find the pre-tax price and tax portion.
