Discount Calculator

Calculate the discounted price and savings in dollars from the original price and discount percentage.

How the Discount Calculator Works

This calculator lets you quickly compute the discounted price and savings from the original price and discount percentage. It is the ideal tool during sales, Black Friday, or any promotional event.

The Discount Formula

The calculation is straightforward:

  • Savings = Original price x Discount percentage / 100
  • Discounted price = Original price - Savings

For example, a product priced at $150 with a 30% discount: savings = 150 x 30 / 100 = $45, and the final price is 150 - 45 = $105.

Watch Out for Stacked Discounts

When multiple discounts are applied in sequence (cascading discounts), the final result differs from the sum of percentages. A 20% discount followed by an additional 10% is not the same as 30%: the second discount is applied to the already-reduced price. In this case, the final price is 72% of the original (not 70%).

When to Use This Calculator

This tool is useful for:

  • Comparing deals during sales, Black Friday, and promotions
  • Verifying the real price after a discount before purchasing
  • Calculating actual savings on one or more products
  • Sharing the result with friends and family

The calculation accounts for rounding to the cent, always giving you a precise and usable result.

Frequently Asked Questions

How do you calculate a percentage discount?
Multiply the original price by the discount percentage and divide by 100. For example, 20% of $80 is 80 x 20 / 100 = $16 off. The final price is 80 - 16 = $64.
How do you find the discount percentage between two prices?
Subtract the sale price from the original price, divide by the original price, and multiply by 100. Formula: (original - sale price) / original x 100.
Does a 50% discount always halve the price?
Yes, a 50% discount cuts the price exactly in half. However, two 25% discounts applied in sequence do not equal a 50% discount -- they result in a 43.75% total discount.
