Discount Calculator
Enter the list price and the discount percentage to see the final price and how much you save. For "extra discount on top" promotions, add a second percentage: the calculator applies the discounts in sequence and shows the true combined (effective) rate — stacking 20% and 10% gives 28% off, not 30%, because the second discount applies to the already-reduced price.
Frequently asked questions
How is a sale price calculated?
Price × (1 − discount/100). An item listed at 850 with 30% off costs 850 × 0.70 = 595, saving you 255.
Why don't 20% and 10% discounts add up to 30%?
The second discount applies to the price after the first one: 100 → 80 after 20% → 72 after another 10%. Total savings are 28, an effective 28% discount. Stacked discounts combine by multiplication: 0.80 × 0.90 = 0.72.
How do I find the discount rate from two prices?
(Old price − New price) ÷ Old price × 100. An item reduced from 850 to 595 is discounted by (255 ÷ 850) × 100 = 30%. Our percentage increase tool covers this direction too.
Can a discount exceed 100%?
No — a 100% discount makes the item free, and anything beyond would mean the seller pays you. The tool therefore accepts rates between 0 and 100.
