What is the difference between sales tax and VAT?

US sales tax is applied at the point of sale to the end consumer. VAT (used in Europe and elsewhere) is collected at each stage of production and built into the price.

How do I reverse-calculate pre-tax price?

To find the pre-tax price from a total: Pre-tax = Total / (1 + Tax Rate/100). For example, $108.50 total ÷ 1.085 = $100 pre-tax.
