Understanding Percentage Discount

A percentage discount represents the reduction in price from the original price, expressed as a percentage. For example, a 20% discount on an item means you pay 20% less than the initial price.

The Formula

The basic formula to calculate the discounted price is:

Discounted Price = Original Price - (Original Price × Discount Percentage / 100)

Step-by-Step Calculation with a Calculator

  1. Identify the Original Price: Note the original price of the item.
  2. Determine the Discount Percentage: Find the discount percentage being offered.
  3. Convert Percentage to Decimal (Optional): If your calculator doesn't have a percentage key, divide the discount percentage by 100 to get its decimal equivalent. For instance, 20% becomes 0.20.
  4. Calculate the Discount Amount:
    • Enter the original price into your calculator.
    • Press the multiplication key (×).
    • Enter the discount percentage.
    • If your calculator has a percentage key (%), press it. Otherwise, multiply by the decimal equivalent (from step 3).
    • The result is the discount amount.
  5. Subtract to Find the Sale Price:
    • Enter the original price again.
    • Press the subtraction key (-).
    • Enter the discount amount (calculated in step 4).
    • Press the equals key (=).
    • The final result is the sale price after the discount.

Example

Let's say a jacket has an original price of $120, and it's on sale for 25% off.

  1. Original Price: $120
  2. Discount Percentage: 25%
  3. Calculate the Discount Amount: $120 × 25% = $30
  4. Subtract to Find the Sale Price: $120 - $30 = $90

Therefore, the sale price of the jacket is $90.

Additional Tips

  • Double Discounts: Some stores offer stackable discounts. In such cases, apply each discount sequentially. For example, if you have a 20% off coupon and an additional 10% off, calculate the first discount, then apply the second discount to the already reduced price.
  • Tax Considerations: Remember that sales tax is usually calculated *after* the discount is applied. Our calculator allows for tax consideration.
  • "Fake" Discounts: Be aware of inflated "original" prices to make discounts seem larger than they are. Always consider the actual value of the item.

FAQs

How do I calculate a 10% discount?

Multiply the original price by 0.10 (or divide by 10) to find the discount amount. Then, subtract that amount from the original price. Our calculator makes this even easier!

How do I find the original price if I only know the discounted price and the discount percentage?

Divide the discounted price by (1 - (discount percentage / 100)).

What are some common types of discounts?

  • Quantity discounts
  • Trade discounts
  • Promotional discounts
