This calculator uses the standard discount calculator formula:
Discount Formula
Sale Price = Original Price × (1 − Discount% / 100)
Frequently Asked Questions
How do I calculate a discount?⌄
Multiply the original price by the discount percentage and divide by 100 to get the discount amount. Subtract from the original price for the sale price.
What is 30% off $120?⌄
30% of $120 = $36. Sale price = $120 − $36 = $84.
How do I find what percentage discount was applied?⌄
Discount % = ((Original Price − Sale Price) / Original Price) × 100. For example, $120 original, $84 sale: ((120−84)/120) × 100 = 30%.
What is a double discount?⌄
A double discount applies two discounts sequentially, not additively. For example, 20% then 10% off: apply 20% first to get 80%, then 10% off that = 72% of original (28% total discount, not 30%).
How do I calculate discount markup?⌄
Markup is the amount added to a cost price. Markup % = ((Selling Price − Cost) / Cost) × 100. This is different from a discount, which reduces a selling price.
Is a 50% discount the same as half price?⌄
Yes. A 50% discount means you pay half the original price. For example, $200 at 50% off = $100.
