What is the Rate of Discount Formula?

The core idea behind the rate of discount is to express the discount amount as a percentage of the original price. Here's the basic formula:

Rate of Discount = (Discount Amount / Original Price) × 100

How to Calculate the Rate of Discount

Let’s break down the steps with an example:

  1. Identify the Original Price: This is the price of the item before any discount is applied.
  2. Determine the Selling Price: This is the price you actually pay for the item after the discount.
  3. Calculate the Discount Amount: Subtract the Selling Price from the Original Price.
  4. Apply the Formula: Divide the Discount Amount by the Original Price, and then multiply by 100 to get the percentage.

For instance, imagine a jacket originally priced at $120 is on sale for $90. The discount amount is $120 - $90 = $30. The rate of discount is ($30 / $120) × 100 = 25%.
