Discount Calculator

Find any missing value in a sale. Whether you want to know the final cost, the original price, or exactly what percentage you're saving, this tool handles all three scenarios instantly.

Sale Price = Original Price × (1 - Discount%)
Sale Price: $100 original with 20% off = $80. Original Price: $80 sale with 20% off = $100.

How do I calculate the original price after a discount?

If you know the sale price and the discount percentage, use this formula: Original Price = Sale Price / (1 - Discount%/100). For example, if an item is $75 after a 25% discount, the original price was $75 / 0.75 = $100.

How do I find the discount percentage I received?

To find the percentage off, use: [(Original Price - Sale Price) / Original Price] × 100. For example, if a $100 item was sold for $80, you saved $20, which is a 20% discount.

What is the "Sale Price" formula?

Sale Price = Original Price × (1 - Discount%/100). This is the most common way to find out what you will pay at the register.

Can I calculate the discount amount directly?

Yes. Discount Amount = Original Price - Sale Price. Or, if you only have the percentage: Original Price × (Discount%/100).
