About Discount Calculator
The Discount Calculator instantly shows the final price and total savings when you apply a percentage discount to any original price. Results update in real time as you adjust either value — no need to click Calculate.
Shoppers use it to compare deals during sales, Black Friday, and clearance events. Retailers and e-commerce managers use it to set promotional prices and verify margin impact before publishing. Teachers use it as a practical percentages exercise.
For stacked discounts (e.g., 20% off a sale price that is already 10% off), apply them sequentially: calculate the first discount, take the result as the new original price, then calculate the second. Stacked discounts are multiplicative — a 20% + 10% stack saves 28% of the original price, not 30%. Use the calculator twice to model each step.
Works on any device — desktop or mobile. All calculations run locally in your browser with no data stored or transmitted. No signup, no account, and no internet connection required after the page loads.
Frequently Asked Questions

Final price = Original price × (1 - Discount% / 100). Savings = Original price × Discount% / 100.
Can I enter multiple discounts?

Does it handle tax?
This calculator shows the price after discount only. Tax calculations are not included.
Can I use decimal discount percentages?

Does it work offline on my phone?
