Discount Calculator
Find the sale price and how much you save from an original price and a percentage off.
Calculate the sale price and your savings
The Discount Calculator instantly shows the final price after a percentage discount and exactly how much you save. Enter the original price and the percent off, and get both numbers at once — perfect for shopping, sales, and quickly checking whether a deal is as good as it looks.
How discounts work
A percentage discount reduces the price by that fraction of the original. The savings are price × discount ÷ 100, and the final price is what's left after subtracting them. For example, 25% off an 80 item saves 20, leaving a final price of 60. Seeing both the savings and the final price helps you judge a deal at a glance.
How to use it
- Enter the original price.
- Enter the discount percentage.
- Read the final price and the amount you save.
Common discounts
| Discount | You pay |
|---|---|
| 10% off | 90% of the price |
| 25% off | 75% of the price |
| 50% off | Half price |
| 70% off | 30% of the price |
Smart shopping tips
- Check the original price — some "sales" inflate it first.
- Stacked discounts apply one after another, not added together (20% then 10% off is 28% total, not 30%).
- Compare unit prices, not just the percentage off.
- A bigger percentage off a cheap item may save less than a small percentage off an expensive one.
Mental math shortcut
To estimate quickly, find 10% by moving the decimal one place left, then scale: 30% off is three times the 10% value. For 25% off, take a quarter of the price as your savings. The calculator above gives the exact figure, but these tricks help when you're standing in a store.

Frequently asked questions
How do I calculate a discount?
Multiply the price by the discount percent and divide by 100 to get the savings; subtract that from the price for the final cost.
How do stacked discounts work?
They apply one after another. 20% then 10% off is 28% total savings, not 30%, because the second applies to the already-reduced price.
Does it show how much I save?
Yes. It shows both the final price and the exact amount saved.
Is it free?
Yes, completely free with no sign-up, running entirely in your browser.
