Does this stack multiple discounts correctly?

This calculator applies a single discount percentage. For stacked discounts (e.g. 20% off, then an extra 10% off), apply this calculator twice, using the sale price from the first calculation as the new starting price.

Is tax applied before or after the discount?

In most U.S. states, sales tax is calculated on the discounted price, which is how this calculator applies it.

How to calculate a discount

Multiply the original price by the discount percentage to find how much you save, then subtract that from the original price to get the sale price. Add sales tax afterward if your state or local rate applies to the discounted price.
