Discount Calculator
Calculate how much you save and the final price after a percentage discount.
Formula
Savings = original price × discount percentage ÷ 100. Sale price = original price − savings.
Example
A 20% discount on 50 gives savings of 10 and a sale price of 40, before any taxes or fees.
Discount Calculator: guide and examples
A discount calculator estimates the reduction from an original price and the resulting sale price. It is useful when comparing offers, planning a promotion, or checking savings before tax, shipping, or other fees.
Formula
Discount amount = original price × discount rate ÷ 100. Sale price = original price − discount amount. For example, 20% off 50 saves 10 and leaves a sale price of 40.
How to use it
- Enter the regular price.
- Enter the advertised discount percentage.
- Check both the savings and final price, then account separately for tax or fees.
Shopping tips
Compare the final price for the same product and quantity. A larger percentage discount does not always mean the lowest price, and successive discounts usually should not simply be added together.
