A discount percentage tells you how much of the original price is removed. The final sale price is the original price minus the discount amount.
Use the calculator first, then read the guide below to understand the formula and examples.
Direct answer
To calculate a discount, multiply the original price by the discount percentage divided by 100. Then subtract that amount from the original price.
Formula
Discount amount = original price × discount percentage ÷ 100. Final price = original price - discount amount.
Example
If an item costs 100 and the discount is 25%, the discount amount is 25. The final price is 75.
Why this matters
Discount calculations help you compare deals properly. A bigger discount percentage does not always mean the best deal if the original price is higher.
Common mistake
Many people only calculate the discount amount and forget to calculate the final price. Both numbers are useful: how much you save and what you actually pay.
FAQs
How do I calculate 10% off?
Multiply the price by 10 ÷ 100, then subtract that amount from the original price.
Is 50% off the same as half price?
Yes. A 50% discount means the final price is half of the original price.
Can tax change the final price?
Yes. If tax is added after the discount, the amount you pay can be higher than the discounted price.
