Formula & Methodology
Savings = Original Price × (Percent Off ÷ 100) Final Sale Price = Original Price - Savings Final Sale Price = Original Price × (1 - (Percent Off ÷ 100))

To compute your sale price: 1. Multiply the original price by the percent off divided by 100 to determine how much money is deducted (your savings). 2. Subtract those savings from the original price to obtain the final amount due at checkout. For instance, with 20% off $100: Savings = 100 × 0.20 = $20; Final Price = 100 - 20 = $80.

Frequently Asked Questions

How do I quickly compute percent off in my head?
For 20% off, move the decimal left one spot to get 10%, then double it and subtract. On a $60 item, 10% is $6, so 20% is $12, leaving $48.
Does this calculator include sales tax?
This tool calculates the discounted merchandise price before tax. If you need sales tax included, use our full Discount Calculator.
Can I apply stacked or double discounts?
Double discounts (e.g. 20% off plus an extra 10% off) apply sequentially, not additively: $100 becomes $80, and 10% off $80 leaves $72 (a total 28% discount, not 30%).
What if percent off is 100%?
A 100% discount means the item is completely free ($0.00).
What is the difference between percent off and markdown?
Retailers use the terms interchangeably: both describe a percentage reduction from the original list price.
