Discount calculator

See the price after a percentage discount.

How it works

Final price = original price × (1 − discount ÷ 100)

Example: an original price of 80 with a 25% discount becomes 60. Enter a discount between 0 and 100. Tax and fees are not included.

How to use this tool

Enter the price before the discount and the discount percentage. Calculate gives the remaining price. Use the same currency throughout; this tool does not convert currencies.

Worked example

For a price of 120 and a 20% discount, the reduction is 120 × 0.20 = 24. The final price is 120 − 24 = 96.

Limits of this tool

The price must be nonnegative and the discount must be between 0% and 100%. Tax, shipping, multiple discounts and currency-specific rounding are not included.

Good to know

Results are computed with 64-bit floating-point numbers. Very large or tiny values can lose precision; the display rounds only after calculation. Non-finite results are rejected.

Everything runs on your device. No inputs are sent to a server.
