Discount Calculator
Calculate the sale price, money saved and effective discount, including a second stacked offer.
Inputs
Formula
- Sale price = price × (1 − d1) × (1 − d2)
- Effective discount = 1 − sale / price
Stacked offers never simply add up: 30% off plus an extra 10% coupon is 37% off, not 40%, because the coupon applies to the already-reduced price. Enter both to see the real saving, plus tax if it is charged on the discounted amount.
