# Percent Off Calculator

Please provide two values below to calculate. Original price
1st Percent off
Final price
Saved 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.
