About this calculator
A percentage discount takes that share off the original price: 25% off an $80 item saves 80 × 0.25 = $20, for a final price of $60.
Stacked discounts multiply rather than add: "20% off, then an extra 10% off" is not 30% off — it's 0.8 × 0.9 = 0.72 of the original, i.e. 28% off. Run each discount through the calculator in turn to see the real final price.

Frequently asked questions
How do I calculate a percentage discount?
Multiply the original price by the discount percentage and divide by 100 to get the saving, then subtract it from the price. 25% off $80 is $80 × 25 ÷ 100 = $20 off, for a final price of $60.
What is 25% off $80?
You save $20 and pay $60. The saving is a quarter of the $80 original, and the final price is the remaining three quarters.
How do stacked discounts work?
They multiply rather than add. "20% off, then an extra 10% off" leaves 0.8 × 0.9 = 0.72 of the original — a 28% discount, not 30%. Run each discount through in turn to see the true final price.
How do I find the original price from a sale price?
Divide the sale price by one minus the discount as a decimal. A $60 item marked 25% off came from $60 ÷ 0.75 = $80.
