Understanding the Basics

Before diving into the calculations, let's define some key terms:

  • Original Price: The initial price of the item before any discount.
  • Sale Price: The price of the item after the discount is applied.
  • Discount Amount: The amount of money saved from the original price.
  • Discount Percentage: The percentage of the original price that is being reduced.

The Formula

The fundamental formula for figuring out a discount percentage is:

Discount Percentage = ((Original Price - Sale Price) / Original Price) * 100

Step-by-Step Calculation

  1. Determine the Original Price: Note the original price of the item.
  2. Find the Sale Price: Identify the discounted price.
  3. Calculate the Discount Amount: Subtract the sale price from the original price.
  4. Apply the Formula: Divide the discount amount by the original price, and then multiply by 100.

Example

Let’s say you want to buy a jacket. The original price is $80, but it's on sale for $60. Here's how to calculate the discount percentage:

  1. Original Price: $80
  2. Sale Price: $60
  3. Discount Amount: $80 - $60 = $20
  4. Discount Percentage: ($20 / $80) * 100 = 25%

Therefore, the discount percentage on the jacket is 25%.

Alternative Calculation Methods

There's another way to look at it. You can calculate what percentage of the original price you *are* paying, and then subtract that from 100%.

  1. Divide the Sale Price by the Original Price: ($60 / $80) = 0.75
  2. Multiply by 100: 0.75 * 100 = 75%
  3. Subtract from 100: 100% - 75% = 25%

This method confirms that the discount is 25%.

Why is this Important?
