Calculate sale prices and savings
Last updated: January 2025
About This Tool
Whether you are shopping for deals or setting promotional prices for your business, understanding discounts helps you make smarter financial decisions. This calculator instantly shows your savings and final prices.
What is Discount Calculator?
A discount is a reduction from the original price of a product or service, usually expressed as a percentage. Discounts can be promotional (sales, clearance), volume-based (bulk purchases), or negotiated (B2B transactions). Understanding discounts helps both consumers save money and businesses strategically price their offerings.
How It Works
The discount calculator takes the original price and discount percentage, multiplies them to find the discount amount, then subtracts from the original price to get the sale price. For multiple items, it calculates total savings across the quantity purchased.
Formula
Sale Price = Original Price x (1 - Discount % / 100)
