Finding a great deal often involves understanding discounts. "Percentage off" and "discount" are essentially the same thing. When a store advertises a sale with a certain percentage off, it's indicating the portion of the original price that will be deducted. Knowing how to calculate this can save you money and ensure you're getting the advertised deal.

Calculate Percentage Off Now! →The Formula for Calculating Percentage Off
Calculating the final price after a percentage discount is straightforward. Here's the formula:
- Convert the percentage to a decimal: Divide the percentage by 100 (e.g., 20% becomes 0.20).
- Calculate the discount amount: Multiply the original price by the decimal.
- Subtract the discount amount from the original price: This gives you the final sale price.
For example, if an item originally costs $50 and is 25% off:
- Decimal equivalent: 25 / 100 = 0.25
- Discount amount: $50 * 0.25 = $12.50
- Sale price: $50 - $12.50 = $37.50
Quick Calculation Tips
Here are a few quick ways to calculate common percentage discounts in your head:
- 10% off: Move the decimal point one place to the left (e.g., 10% of $100 is $10).
- 20% off: Calculate 10% and then double it.
- 25% off: Divide the price by 4.
- 50% off: Divide the price by 2.

Common Percentage Off Scenarios
Percentage discounts are everywhere. Here are a few examples:
- Retail Sales: "30% off all shoes!"
- Coupon Codes: "Get 15% off your entire order!"
- Clearance Items: "75% off all clearance items!"
- Black Friday/Cyber Monday Deals: "Up to 80% off select electronics!"
Being able to quickly calculate these discounts helps you make informed purchasing decisions.
Understanding Stackable Discounts
Sometimes, you might encounter "stackable" discounts, where you can apply multiple discounts to the same item. However, it's important to understand how these discounts are applied. A "stackable additional discount" means getting a further percent off of a product *after* a discount is already applied. Using the same example, assume that the 20% discount is a discount applied by the store to the product. If you have a coupon for another 15% off, the 15% off would then be applied to the discounted price.
Let's calculate that:
- Original Price: $279
- 20% Off: $279 * 0.2 = $55.80 discount.
- Price after first discount $279 - $55.80 = $223.20
- 15% off the discounted price : $223.20 * 0.15 = $33.48
- Final price = $223.20 - $33.48 = $189.72
With a 20% discount off of $279, and an additional 15% off of that discounted price, you would end up saving a total of: $55.80 + $33.48 = $89.28. This equates to a 32% discount, rather than a 35% discount, and this calculation is how our handy discount calculator is intended to be used.
Percentage Off Examples
Let's work through some examples for common discounts:
- How much is 20 percent off?
Taking 20 percent off an item requires you to take the original price and divide it by 10, then double that number. Finally, subtract the doubled number from the original number. - How much is 10 percent off?
Divide the number by 10. Subtract this new number from your original number. - How much is 15 percent off?
Divide your original number by 20 (halve it then divide by 10). Multiply this new number by 3. Subtract the number from step 2 off of your original number. - How much is 30 percent off?
Divide the number by 10. Triple this new number. Subtract your triple from your starting number.
