Discount Calculator

How do you calculate discounts? Use these free calculators to see how much you'll pay before and after discounts are applied to your next purchase.

Shopping can sometimes feel like a math quiz.

When discounts are applied, how much are you really paying?

How do I calculate a discount percentage?

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

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

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

How do you calculate a 5% discount?

To calculate a 5% discount off your item, follow these steps:

1. Find the original price of the item.
   
2. Divide the original price by 100.
   
3. Then, multiply by 5.
   
4. Subtract that number from the original price.
   
5. The new number is the discounted price.

5% Discount Example
$200 (original price) / 100 = 2
2 x 5 = 10
200 - 10 = 190
Discounted price: $190

Percentage discount: This is when a percentage (between 1 - 100) is deducted from the item's price (for example, 10% off $50 = $45)

Flat amount discount: This is when a flat dollar amount is deducted from the item's price (for example $5 off $50 = $45)

"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)
