Frequently Asked Questions

Is tax calculated before or after the discount?▾

Tax is calculated on the discounted (sale) price, not the original price. This is how most US states calculate sales tax.

Can I stack multiple discounts?▾

This calculator applies one discount. For stacking, calculate the first discount, then use that result as the new original price for the second discount.

What if there's no sales tax?▾

Simply leave the tax rate at 0 or empty. The final price will equal the sale price.
