Frequently Asked Questions
How do I calculate a discount price?
Sale Price = Original Price × (1 − Discount% ÷ 100). For a $120 item at 25% off: $120 × (1 − 0.25) = $120 × 0.75 = $90. The dollar savings = Original Price × (Discount% ÷ 100) = $120 × 0.25 = $30. You can also multiply the original price by the discount percentage to find the discount amount, then subtract from the original.
How do I calculate what percentage off a sale is?
Discount % = ((Original Price − Sale Price) ÷ Original Price) × 100. If a $80 item is on sale for $60: ((80 − 60) ÷ 80) × 100 = 25% off. Use this to compare deals — a "$30 off" promotion on a $90 item (33% off) beats a "20% off" promotion on the same item ($72 sale price).
How do stacked discounts work?
Stacked (successive) discounts are applied sequentially, not added together. A 20% discount followed by a 10% discount on a $100 item: first discount gives $80, then 10% off $80 = $72. The effective combined discount is 28%, not 30%. Retailers use stacked discounts to make promotions sound larger than they are. Our calculator applies one discount at a time.
