How it’s calculated
Sale price = price × (1 − discount)Discount = (regular − sale) ÷ regular- Stacked discounts multiply:
final = price × (1 − d1) × (1 − d2). 20% then 10% is1 − 0.8 × 0.9 = 28%off, not 30%. - Buy X get Y at z% off:
discount on the whole order = Y × z ÷ (X + Y). Buy 2 get 1 free is 33.3% off each item. - Lowest price that keeps margin m:
cost ÷ (1 − m − fee %). Deepest discount:1 − lowest price ÷ regular price.
