How do I calculate a discount?

Multiply the original price by the discount percentage divided by 100 to get the amount saved, then subtract that from the original price to get the sale price. The calculator does both steps instantly.

Can I find the original price from a sale price?

Yes. Switch to reverse mode and enter the sale price and the discount percentage, and the calculator works out what the item cost before the discount was applied.

Do you save what I type?

No. Every calculation runs locally in your browser. Nothing you enter is uploaded or stored anywhere.

What is a Discount Calculator?

A discount calculator turns a “percent off” sticker into the numbers that actually matter: the final price you will pay and the money you save. Enter the original price and the discount percentage and it instantly shows both. It also works in reverse, letting you recover the original price from a discounted one. Everything is computed in your browser as you type, so checking a deal takes only a moment.

How to Use

Use Cases

Discounts are everywhere, and they are not always as generous as they look. Use this calculator while shopping in-store or online to confirm the actual price after a markdown, to compare two offers with different percentages and starting prices, or to check a stacked coupon. Retailers and resellers use it the other way around to set sale prices and to reverse-engineer margins. Anytime a price tag shows a percentage, this tool tells you what it means in real money.

Why Use This

Percentage-off math is easy to misjudge, especially when comparing offers or stacking discounts. This calculator removes the doubt with an exact figure, works in both directions, and keeps your numbers private by running entirely on your device. There is nothing to install and no account to create.

Getting the Most From Discounts

The headline percentage is only part of the story. A 40% discount on an overpriced item can still cost more than a 20% discount on a fairly priced one, so always compare final prices rather than percentages alone. Watch out for discounts applied before tax versus after, and be cautious with “stacked” offers, which sometimes apply the second discount to the already-reduced price rather than the original. Using the reverse mode to confirm the true original price is a quick way to spot inflated “was” prices.
