Additional discount


A percent off of a product or service is a common discount format. A percent off of a product means that the price of the product is reduced by that percent. For example, given a product that costs $279, 20% off of that product would mean subtracting 20% of the original price from the original price. For example:

20% of $279 = 0.20 × 279 = $55.80

$279 - $55.80 = $223.20

You would therefore be saving $55.80 on the purchase for a final price of $223.20.

For this calculator, a "stackable additional discount" means getting a further percent off of a product after a discount is applied. Using the same example, assume that the 20% discount is a discount applied by the store to the product. If you have a coupon for another 15% off, the 15% off would then be applied to the discounted price of $223.20. It is not a total of 35% off of the original price. It is less:

15% of $223.20 = $33.48

$223.20 - $33.48 = $189.72

Thus, with a 20% discount off of $279, and an additional 15% off of that discounted price, you would end up saving a total of:

$55.80 + $33.48 = $89.28

This equates to a 32% discount, rather than a 35% discount, and this calculation is how the calculator is intended to be used. As an example, to more efficiently compute the discount described above:

Final price = (0.80 × 279) × 0.85 = $189.72

This is because 80% of the original price is the same as subtracting 20% of the original price from the original price. The same is true for 85% and 15% case applied to the discounted price.

What is Meant by Percentage Off?

In mathematics, the percentage off of the product is defined as the price of the product which is reduced by some percentage from the original price of the product. The procedure to calculate the percentage off for the product is given as follows:

  1. Subtract the sales price form the original price

  2. Divide the discount price by the original price

  3. Finally, multiply the solution by 100

For example, if the cost/original price of the product is Rs. 100 and the selling price is Rs. 80, then the percentage off is calculated as:

Step 1: 100 – 80 = 20

Step 2: 20/100=  0.2

Step 3: 0.2 x 100 = 20

Hence, the percentage off for the product is 20, i.e. 20%.
