This calculator is for informational purposes only and does not constitute financial advice.

Calculates the discount amount as (price x percent) / 100 and subtracts it from the original price to get the final price.

Use cases

  • Calculating the final price of a sale.
  • Comparing offers with different discount percentages.
  • Verifying the discount applied to a purchase.

How it works

  1. 1

    Enter the original price

    Type the price before the discount.

  2. 2

    Enter the discount

    Type the discount percentage to apply.

Technical details

  • Example: an $80 item with 25% off costs 80 − (80 × 25 / 100) = $60; you save $20.
  • Final price and savings are rounded to 2 decimal places (cents). The calculator has no currency, so it works for dollars, euros or anything else.
  • A discount above 100% would give a negative price, which makes no commercial sense.
  • You can type decimals with a comma or a dot (12.5 or 12,5).

Frequently asked questions

Does it apply multiple successive discounts?

No, this calculator applies a single discount. For successive discounts, feed the result of one as the starting price for the next.

Is 20% off plus 10% off the same as 30% off?

No. Successive discounts apply to the result of the previous one: $100 with 20% off becomes $80, and a further 10% off takes it to $72, which is 28% in total, not 30%.
