How Discounts Work
A discount reduces the original price by a percentage. Use the tabs to find sale price, reverse-calculate the original price, or find the discount percentage from two prices.
Sale Price = Original x (1 - Discount%/100)
Discount % = (Original - Sale) / Original x 100
Frequently Asked Questions
Multiply the original price by 0.20 to get the discount amount, then subtract from the original. Example: 20% off $150 = $150 x 0.20 = $30 savings, final price = $120.
Divide the sale price by (1 - discount%). Example: if $75 is 25% off, original = $75 / 0.75 = $100.
