Free Discount Calculator Online
Stacked multi-discounts, reverse price & tax integration
The Discount Calculator computes the final sale price after one or more percentage discounts, including stacked discounts where a second discount applies to the already-reduced price. It also runs in reverse — enter the original and sale price to find the discount percentage applied.
Frequently Asked Questions
About the Discount Calculator
Discount calculations are deceptively tricky because stacked discounts do not simply add together. A product marked "50% off + an extra 20% off" is not 70% off — the second discount applies to the already-reduced price, making the combined discount 60%. This calculator handles stacked discounts correctly and shows the true effective discount percentage.
The reverse mode (find discount percentage from original and sale price) is useful for retailers analyzing competitor pricing, shoppers verifying that a advertised discount is actually applied, and accountants computing discount rates from invoice data.
Tax integration lets you add GST, VAT, or sales tax to the discounted price to find the final checkout amount. This makes the calculator useful for both consumers comparing shopping deals and business owners setting promotional prices that remain profitable after tax.
