# Discount Calculator

## Calculator Use

Calculate the list price, discount percentage or sale price given the other two values. You will also find the discount savings amount.

### Calculate Discount from List Price and Sale Price

The discount is list price minus the sale price then divided by the list price and multiplied by 100 to get a percentage.

Where:

- L = List Price
- S = Sale Price
- D = Discount percentage

#### Example

If the list price of an item is $120 and the final sale price is $90 then discount is calculated as follows:

### Calculate Sale Price from List Price and Discount

The sale price is the list price minus the product of the discount divided by 100 and multiplied by the list price.

#### Example

If the list price of an item is $120 and discount is 75% then the final sale price is calculated as follows:

### Calculate List Price from Discount and Sale Price

The list price is the sale price divided by the difference of 1 minus the result of discount divided by 100.

#### Example

If the sale price of an item is $40 and the discount is 20% then the list price is calculated as follows:

### Sample Discount Percentage Calculation

James bought a vintage lava lamp at a sale price of $89.63. The original price was $165.99. What was the percentage discount on the original price of the lava lamp?

Using the formula above, list price = L = 165.99, and price sale = P = 89.63.

James got a 46% discount on the lava lamp.
