Discount Calculator
Calculate the final price and savings for any percentage-off discount.
Sale signs advertise a percentage off, but the actual dollar amount you save — and whether it's actually a good deal compared to another offer — isn't always obvious at a glance, especially when stacking multiple discounts or comparing different percentage-off deals on different original prices.
This calculator takes the original price and discount percentage and instantly shows both the amount you save and the final price you'll pay. It's useful for quick in-store or online comparisons, verifying that a checkout total matches the advertised discount, or figuring out the actual price before adding a coupon on top of an already-discounted item.
One subtlety worth knowing: stacked discounts (like 20% off, then an additional 10% off) don't add up to 30% off the original price — each discount applies to the already-reduced price, so two sequential discounts always total slightly less than their sum would suggest.
