How to Calculate Discounted Price
Formula: Discounted Price = Original Price × (1 – Discount% / 100)
Example: A product costs ₹2,499. It's on 30% discount. Discounted price = 2,499 × (1 – 0.30) = 2,499 × 0.70 = ₹1,749.30. You save ₹749.70.
Successive Discounts — When There's a Discount on a Discount
Many stores offer layered discounts: "40% off + additional 20% off." This is NOT the same as 60% off. The correct calculation is:
Effective Discount = 1 – (1 – 0.40) × (1 – 0.20) = 1 – 0.60 × 0.80 = 1 – 0.48 = 52% effective discount.
Our discount calculator handles successive discounts so you know exactly what you're actually saving.
Reverse Discount — Finding Original Price
Bought something at ₹840 after a 30% discount? What was the original price? Formula: Original Price = Sale Price / (1 – Discount% / 100) = 840 / 0.70 = ₹1,200.
Frequently Asked Questions
How do I calculate 20% discount on a price?
Multiply the original price by 0.20 to get the discount amount. Subtract it from the original price. Example: 20% off ₹1,500 → ₹1,500 × 0.20 = ₹300 discount → Final price = ₹1,200.
What is the formula for discount percentage?
Discount % = ((Original Price – Sale Price) / Original Price) × 100. Example: Original ₹2,000, Sale ₹1,600 → Discount % = (400/2,000) × 100 = 20%.
Is 40% + 20% discount equal to 60% off?
No. Successive discounts of 40% and 20% equal an effective discount of 52%, not 60%. The second discount applies to the already-reduced price, not the original.
