The Basic Discount Formula

The most fundamental way to think about discount calculation involves these two simple formulas:

  • Discount Amount = List Price - Selling Price
  • Discount Percentage = (Discount Amount / List Price) × 100

Where:

  • List Price: The original price of the item.
  • Selling Price: The price you actually pay after the discount.

Step-by-Step Discount Calculation

Let's break down how to use these formulas with an example:

  1. Identify the List Price: Suppose a jacket has a list price of $100.
  2. Identify the Selling Price: You buy the jacket for $75 during a sale.
  3. Calculate the Discount Amount: $100 (List Price) - $75 (Selling Price) = $25 (Discount Amount)
  4. Calculate the Discount Percentage: ($25 (Discount Amount) / $100 (List Price)) × 100 = 25%

Therefore, you received a 25% discount on the jacket.

Finding the Selling Price When Given the Discount Percentage

Sometimes, you know the original price and the discount percentage, but need to calculate the final selling price. Here's the formula:

Selling Price = List Price × (1 - (Discount Percentage / 100))

Let's say that same jacket ($100 list price) is advertised as 30% off. The math looks like this:

$100 × (1 - (30 / 100)) = $100 × (1 - 0.3) = $100 × 0.7 = $70

So, the selling price is $70.

Alternative Method: Calculate the Discount Percentage Directly

Another easy way to calculate the final price is to directly determine the percentage you *will* pay. If an item is 20% off, you are paying 80% of the original price.

For example, to determine that 70% of $70 is $49, you can calculate it like so: 70/100 * $70 = $49
