Percent Off Calculator
Use a percent off calculator to estimate sale price, work backward to the original price, or compare original and final prices to find the equivalent discount rate.
How to use this calculator
How percent off and stacked discounts work
A percent-off discount reduces a price by a percentage of the original amount. If a second stackable discount is applied, it reduces the already-discounted price rather than simply adding the two percentages together.
- Use Final price mode when you know the original price and the discount rate and want the sale price immediately.
- Use Original price mode when you know the discounted checkout price and want to estimate the price before the markdown.
- Use Discount rate mode when you only know the original price and final price and want the equivalent percent off.

FAQ
Common Percent Off questions
How do I calculate percent off a price?
Multiply the original price by the discount rate to find the amount saved, then subtract that savings amount from the original price to get the final price.
Is 20% off plus 15% off the same as 35% off?
No. A stackable second discount is applied to the already-discounted price, so the combined discount is lower than simply adding the two percentages together.
When should I use the original-price mode?
Use it when you know the final sale price and the discount rate and want to recover the estimated original list price before the discount was applied.
