How to use the Discount Calculator

- Results update automatically as you type; you can also press Calculate.

Formula and method
Worked example
With original price = $80, discount = 25 %, the Discount Calculator returns sale price: $60.00; you save: $20.00.
Tips for better results
- Stacked discounts multiply rather than add: 30% + 20% off is 44% off, not 50%.
- Compare unit prices, not package prices, to find the real deal.
- Bookmark the tools you use often — every page works offline once loaded.
