Discount Formulas for Sale Price and Percent Off

Sale Price

Sale Price = Original × (1 - Discount/100)

Discount Percentage

Discount % = ((Original - Sale) / Original) × 100

Stacking Discounts: When applying multiple discounts, they compound rather than add. A 20% + 10% discount is actually 28%, not 30%.

Tip: Always calculate the effective discount when comparing stacked promotions to single discount offers.
