Discount Calculator
Find the discount amount and final price after a sale discount. Useful for shopping, pricing, and promotions.
Discount Amount
- Discount = Original Price × Discount Rate / 100
Final Price
- Final Price = Original Price − Discount Amount
If an item costs 100 and the discount is 20%, the discount is 20 and the final price is 80.
Enter the original price and discount percentage. The calculator subtracts the discount amount from the original price.
Use it when comparing sale offers, checking promotions, or calculating customer discounts.
Do not subtract the percentage number directly from the price; first convert the percentage into a money amount.
