What Is a Discount Calculator?

A discount calculator converts percent-off deals into real dollars: sale price, amount saved, and true percent when you only know two of the three numbers. Stacked mode applies coupons in sequence the way stores do.

Discount Formulas

Sale = Original × (1 − % ÷ 100)
% Off = ((Original − Sale) ÷ Original) × 100
Original = Sale ÷ (1 − % ÷ 100)

Frequently Asked Questions

How do you calculate a discount?

Multiply original by percent ÷ 100 for savings, then subtract from original.

How do stacked discounts work?

Apply each % to the remaining price — 20% then 10% off $100 = $72, not $70.

Is this discount calculator free?

Yes — free and private.
