Shopping can sometimes feel like a math quiz.
When discounts are applied, how much are you really paying?
With the calculators in this article, you'll find out:
How do I calculate a discount percentage?
To calculate the discount percentage taken off your item, follow these steps:
- Find the original price of the item before the discount.
- Find the price of the item after the discount was applied.
- Subtract the after-discount price from the original price.
- Divide that by the original price.
- Multiply by 100.
- 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
To calculate the original price of an item before the discount is applied, follow these steps:
- Find the price of the item after the discount was applied.
- Find the discount percentage that was applied to the price.
- Divide the discount percentage by 100.
- Subtract that number from 1.
- Divide the after-discount price by that number.
- 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
To calculate the price of an item after the discount is applied, follow these steps:
- Find the original price of the item.
- Find the discount percentage that will be applied to the price.
- Divide the original price by 100.
- Multiply by the discount percentage.
- Subtract that number from the original price.
- 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
How do you calculate a 5% discount?
To calculate a 5% discount off your item, follow these steps:

2 x 5 = 10
200 - 10 = 190
Discounted price: $190

"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)
