A discount percentage tells you how much money comes off the original price. This is useful for sales, coupons, retail promotions, subscriptions, and tax-free shopping events.
Use the Percentage Calculator to find the discount amount or final sale price. You can also use the Sales Tax Calculator afterward to estimate the final checkout total in the United States or Canada.
Discount formula
Discount amount = original price x discount percentage. Sale price = original price – discount amount.
Quick examples
- 20% off $100 saves $20, so the sale price is $80.
- 30% off $200 saves $60, so the sale price is $140.
- 50% off $80 saves $40, so the sale price is $40.
Remember sales tax
In many US states and Canadian provinces, sales tax is applied after the discount. That means the final amount you pay may be higher than the sale price shown on the tag.
FAQ
Is 50% off the same as buy one get one free?
Sometimes, but not always. Buy one get one free usually requires buying two items, while 50% off may apply to one item.
How do I calculate an extra discount?
Apply discounts one at a time. A 20% discount followed by another 10% discount is not the same as 30% off.
