Imagine your favorite shirt is on sale. It originally cost $50, but now it's listed for $40. That's a $10 savings! But what percentage discount are you actually getting? Let's break it down.

The Discount Percentage Formula

The formula for calculating discount percentage is straightforward:

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

Let's apply this to our shirt example:

((50 - 40) / 50) * 100 = (10 / 50) * 100 = 0.2 * 100 = 20%

So, you're getting a 20% discount on the shirt!

A Step-by-Step Guide to Calculating Discount Percentage

  1. Find the Original Price: This is the price before any discount is applied.
  2. Find the Sale Price: This is the price after the discount is applied.
  3. Calculate the Savings: Subtract the sale price from the original price.
  4. Divide the Savings by the Original Price: This gives you the discount as a decimal.
  5. Multiply by 100: This converts the decimal to a percentage.

Examples of Calculating Discount Percentage

Example 1: Handbag Savings

You want to buy a handbag that originally costs $200. It's on sale for $150. What's the discount percentage?

Discount Percentage = (($200 - $150) / $200) * 100 = (50 / 200) * 100 = 0.25 * 100 = 25%

You are saving 25% on the handbag.

Example 2: Electronics Deal

A TV is marked down from $800 to $600. What is the discount percentage?

Discount Percentage = (($800 - $600) / $800) * 100 = (200 / 800) * 100 = 0.25 * 100 = 25%

The TV has a 25% discount.
