Percent Off Calculator
- Browser-based
- No signup
This percent off calculator finds the discounted price and dollar savings from an original price and discount percentage. Enter list price and percent off for shopping, markdowns, or coupon math.
Stacked discounts do not add linearly—30% off then an extra 20% is not 50% off total. Apply each step sequentially for accurate math.
Tax is usually calculated on the discounted price, but rules vary by jurisdiction.

Frequently asked questions
How is percent off calculated?
Sale price = Original × (1 − Discount% ÷ 100). Savings = Original − Sale price.
Does this include tax?
No. Enter pre-tax list price; add tax separately according to local rules.
Can I enter a dollar discount instead?
This tool expects a percentage. Subtract a fixed dollar coupon manually from the original price.
