Discount Calculator

Multiply the original price by the discount percentage and divide by 100 to get the discount amount. Subtract that from the original price to get the sale price. For example, 20% off $50 = $50 × 0.20 = $10 saved, so the sale price is $40.

A stacked discount applies one percentage off, then applies a second percentage off the already-discounted price. For example, 20% off then 10% off is not the same as 30% off — the effective combined discount is 28%.

No. Applying 20% off a $100 item gives $80. Then 10% off $80 gives $72. The total saving is $28, which is a 28% effective discount — not 30%.

Divide the sale price by (1 minus the discount rate). For example, if an item is $72 after a 20% discount, the original price = $72 ÷ 0.80 = $90.

A discount is a reduction from the regular price for a promotional period. A markdown is a permanent reduction in price, often used in retail when products are being cleared. Both are calculated the same way mathematically.
