How Sales Tax is Calculated
Sales tax is calculated as a percentage of the purchase price. In the US, the total sales tax often includes both state and local components.
Total = Price × (1 + Tax Rate)
To extract the pre-tax price from a total that includes tax:
Pre-Tax Price = Total ÷ (1 + Tax Rate)
