How to use this tool
Enter original price and discount percentage. Calculate for sale price and amount saved.
Formula & methodology
This discount calculator – sale price after % off applies the standard relationship below. Intermediate values are kept at full precision; only the displayed result is rounded.
sale = price x (1 - discount/100); saved = price - sale
Worked example
An item priced at 2,500 with 20% off: discount = 2,500 × 0.20 = 500, so you pay 2,500 − 500 = 2,000 and save 500. For stacked offers (20% then a further 10%), apply them one after another rather than adding them to 30%.
Tips for accurate results
Compare unit prices after discount for bulk items.
Additional tax may apply on discounted price depending on jurisdiction.
Verify whether discount applies to MSRP or already-reduced price.
Enter amounts in the currency you shop in—no auto conversion.
