Frequently Asked Questions
Multiply the original price by the discount percentage divided by 100, then subtract from the original price. For example, 25% off $200 = $200 × 0.25 = $50 saved, so the sale price is $150.
Divide the sale price by (1 − discount% / 100). If you paid $150 after a 25% discount, the original price was $150 ÷ 0.75 = $200.
Both reduce the selling price, but a discount is typically a temporary promotional reduction, while a markdown is a permanent reduction in the listed retail price.
Apply each discount sequentially. A 20% then 10% discount is not 30% — it is: $100 × 0.80 × 0.90 = $72, which is a 28% total discount.
Yes. A 50% discount means the sale price is exactly half the original price. You save the same amount as you pay.
