割引計算機

What this tool does

Take a percent off a price and see the amount saved and the final price. Shoppers and anyone writing a sale price can use it when the offer is a simple percent off. Type plain numbers: a currency symbol is rejected, and the discount cannot go above 100%.

How to use

1. Enter the original price as a number, without a currency symbol.
2. Enter the discount percentage.
3. Press Calculate to see the discount amount and the final price.

Examples

• 50 off by 20%

  The discount is 10. The final price is 40.

• A 100% discount

  The final price is 0.

How it works

The discount amount is original price × discount ÷ 100. The final price is the original price minus that amount. The tool does not assume a currency, so 19.99 means 19.99 in whatever unit you are using.

Limitations

Type the price and the percent as plain numbers. A currency symbol is invalid, and a discount above 100% is rejected. Sales tax and a tip split are not part of this subtraction.

FAQ

Is the Discount Calculator free?

Yes. Taking a percent off a price and showing the amount saved is free here, with no signup.

Can I enter a currency symbol?

Enter numbers only. Adding a symbol such as $ or € will be treated as invalid input.

Is my input sent to a server?

No. The price and the percent stay on this page for the subtraction. They are not posted to a server or saved in local storage.

How do I calculate a discount?

Multiply the price by the discount percent and divide by 100 to get the amount off, then subtract it from the price. 25% off $80 is $20 off, so you pay $60.

Are two discounts of 20% the same as 40% off?

No. A second 20% is taken from the already reduced price, so 20% off and then another 20% off is 36% off in total, not 40%.
