About Discount Calculator

A discount calculator helps estimate a sale price from an original price and a discount percentage. Enter the values shown by the seller, then check taxes, delivery and other charges separately.

How to use Discount Calculator

  1. Enter the original price before discount.
  2. Enter the discount percentage shown by the seller.
  3. Select Calculate to see the estimated amount saved and discounted price.
  4. Check that the discount is applied to the correct items and price basis.
  5. Add taxes, delivery and fees separately if you need a final checkout estimate.

Working backwards

If you know the sale price and the discount, you can find the original price by dividing the sale price by one minus the discount rate. A price of 750 after a 25 percent discount means the original was 750 divided by 0.75, which is 1,000. Compare offers by looking at the final price you pay, including delivery, tax and any conditions on the coupon.
