The Basic Formula

The most direct way to calculate the percentage of a discount involves knowing the original price and the sale price. Here's the formula:

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

Step-by-Step Calculation

  1. Find the Savings: Subtract the sale price from the original price to determine the amount saved.
  2. Divide by the Original Price: Divide the amount saved by the original price.
  3. Multiply by 100: Multiply the result by 100 to express the discount as a percentage.

Example: A jacket originally priced at $120 is on sale for $90. What is the discount percentage?

  1. Savings = $120 - $90 = $30
  2. $30 / $120 = 0.25
  3. 0.25 * 100 = 25%

Therefore, the jacket has a discount of 25%.

While the formula is straightforward, manually calculating percentages can be time-consuming. Fortunately, our percentage calculator streamlines this process. Simply enter the original price and sale price, and the calculator will instantly display the discount percentage and the amount you save. It's quick, accurate, and available on both your phone and computer!

Understanding Different Types of Discounts

Discounts come in various forms, but they all reduce the original price. Common types include:

  • Percentage Discounts: A percentage of the original price is deducted (e.g., 20% off).
  • Fixed Amount Discounts: A fixed dollar amount is deducted (e.g., $10 off).
  • Quantity Discounts: Offered when you purchase multiple units of the same item.
  • Promotional Discounts: Temporary discounts to boost sales (e.g., seasonal sales).

Fake Discounts: Spotting the Deception

Be cautious of "fake discounts," where the original price is inflated to create the illusion of a significant saving. Always compare prices with other retailers to ensure you're getting a genuine deal. Using our percentage calculator, you can quickly verify if the advertised discount is accurate.
