Quick answer
Sale price = original price × (1 − discount/100). Two successive discounts of a% and b% equal a single discount of a + b − (a × b ÷ 100) percent, so 20% + 10% is 28%, not 30%.
How to use the Discount Calculator
- Enter the original price.
- Enter the discount %.
- Optionally add a second discount.
- Read the final price, savings and effective discount.
Worked example
₹2,500 with 20% + 10% off: after 20% = ₹2,000; after another 10% = ₹1,800. You save ₹700, an effective 28% discount.
Formula
Final = Price × (1 − d1 ÷ 100) × (1 − d2 ÷ 100) Effective % = (1 − Final ÷ Price) × 100
Frequently asked questions
Is 20% + 10% the same as 30% off?
No. The second discount applies to the already-reduced price, so the combined discount is 28%.
