## Discount Calculator Formula:

There are 3 things to be calculated

* Discount

* List Price

* Sale Price

Formula to Calculate Discount .

Discount Percentage (D) = [ (list price – sale price) / list price ] x 100

D = [(L – S)/L]x 100

Example,

If the list price of an item is $200 and the final sale price is $160 then what is the discount offered.

D = [(L – S)/L]x 100

D = [(200 – 160) / 200] x 100

D = 0.2 x 100

D = 20 %

The discount offered on the product is 20% . Discount = List Price – Sales Price, $200 – $160 = $40.00.

Formula to Calculate List Price.

List Price (L) = Sale Price (S) / (1 – Discount Percentage (D) / 100 )

L = S / (1- D/100)

Example,

If the sale price of an Item is $85 and the discount is 15% then what is the list price ?

L = S / (1- D/100)

L = 85 / (1 – 15/100)

L = 85 / 0.85

L = $100

The list Price is $100 and the discount on the product is $15.

Formula to Calculate Sale Price.

Sale Price (S) = List Price (L) – (Discount percentage / 100) x List Price (L)

S = L – (D/100) x L

Example,

If the list price of an item is $150 and the discount is 20% then what is the sale price ?

S = L – (D/100) x L

S = 150 – (20/100) x 150

S = 150 – 30

S = $120

The sale price is $120.
