Sales Tax and VAT
US sales tax is added at the register and set by states, counties and cities, so the combined rate depends on where you buy. Prices in many other countries already include VAT or GST. To find the price before tax, divide the total by 1 plus the rate; simply subtracting the rate from the total overstates the tax.
The Formulas
Tax = price × rate
Price before tax = total ÷ (1 + rate)
Rate = (total − price) ÷ price
Rates are entered as percentages, e.g. 8.25 for 8.25%.
