FAQ
Divide the saving by the original price and multiply by 100. For example, saving $25 on a $100 item is (25 ÷ 100) × 100 = 25% off.
Divide the sale price by (1 − discount/100). A $79 item after 30% off was originally 79 ÷ 0.70 = $112.86.
Apply them sequentially. 20% off then 10% off a $100 item gives $72 — that is 28% off, not 30%. Stacked discounts always save less than the sum of their percentages.
