Formula

Discounted Price = Original × (1 - Discount%/100)

Convert the discount percentage to a decimal, subtract from 1, then multiply by the original price.

Worked Example

Original Price: $80, Discount: 25% Step 1: Discount amount = 80 × 0.25 = $20 Step 2: Sale price = 80 - 20 = $60 Result: You pay $60 (save $20)

How Do Discounts Work?

A discount reduces the original price of a product or service by a set percentage or fixed amount. Percentage discounts are the most common, where you multiply the original price by the discount rate to find the amount saved. Stacked discounts (e.g., 20% off then an additional 10% off) do not add up to 30%; instead, each discount is applied sequentially to the already-reduced price.
  • A 25% discount on $80: savings = $80 x 0.25 = $20, final price = $60
  • Two 15% discounts do not equal 30% off; they equal about 27.75% total
  • To find the original price: Original = Sale Price / (1 - Discount %)
  • Buy-one-get-one (BOGO) is effectively a 50% discount when buying two items

Knowing how to calculate discounts helps you make better purchasing decisions and spot genuine deals during sales events.

You can also calculate changes using our Percentage Decrease Calculator, Markup Calculator or Sales Tax Calculator.

Frequently Asked Questions

How do I calculate the final price after a discount?

Multiply the original price by (1 - discount/100). For 25% off $80: 80 × 0.75 = $60.

How do I find the original price from the sale price?

Divide the sale price by (1 - discount/100). If $60 after 25% off: 60 / 0.75 = $80.

How do stacked discounts work?

Apply them sequentially. 20% then 10% off $100: $100 × 0.80 × 0.90 = $72 (not 30% off).
