How do I calculate a discount percentage?

Discount Calculator

To calculate the discount percentage taken off your item, follow these steps:

  1. Find the original price of the item before the discount.
  2. Find the price of the item after the discount was applied.
  3. Subtract the after-discount price from the original price.
  4. Divide that by the original price.
  5. Multiply by 100.
  6. This number is the percentage that was deducted from the item price.

Calculate discount percentage example
$125 (original price) - $100 (after-discount price) = $25
25 / $125 = 0.2
0.2 x $100 = 20
Discount percentage = 20%

How to find the original price before a discount

Price Before Discount Calculator

To calculate the original price of an item before the discount is applied, follow these steps:

  1. Find the price of the item after the discount was applied.
  2. Find the discount percentage that was applied to the price.
  3. Divide the discount percentage by 100.
  4. Subtract that number from 1.
  5. Divide the after-discount price by that number.
  6. This number is the original price of the item, pre-discount.

Calculate price before discount example
20 (discount percentage)/ 100 = 0.2
1 - 0.2 = 0.8
$100 / 0.8 = 125
Price before discount = $125

How to find the price after a discount

Price After Discount Calculator

To calculate the price of an item after the discount is applied, follow these steps:

  1. Find the original price of the item.
  2. Find the discount percentage that will be applied to the price.
  3. Divide the original price by 100.
  4. Multiply by the discount percentage.
  5. Subtract that number from the original price.
  6. This number is the discounted price.

Calculate price after discount example
$125 (original price) / 100 = 1.25
1.25 x 20 (discount percentage) = 25
$125 - 25 = $100
Price after discount = $100

"Buy one, get one" discount: This is when you buy one item at full price and get a second item discounted (or even free!)

Quantity discount: This is when the retailer gives you a discount for buying multiple items

Trade discount: This is a discount usually offered by a wholesaler to a retailer (for example, a flower wholesaler giving a discount to a florist who sells their flowers)
