- Mode 3 – Find Discount %: Know original price and sale price → calculate what percentage discount was applied.

Discount Formula – All 3 Calculations
1. Calculate Discounted Price:
Discount Amount = Original Price × Discount% / 100
Final Price = Original Price – Discount Amount
Example: ₹1,000 with 20% discount
Discount = 1,000 × 20/100 = ₹200
Final Price = 1,000 – 200 = ₹800
Final Price = Original Price – Discount Amount
Example: ₹1,000 with 20% discount
Discount = 1,000 × 20/100 = ₹200
Final Price = 1,000 – 200 = ₹800
2. Find Original Price from Discounted Price:
Original Price = Sale Price / (1 – Discount%/100)
Example: Sale price ₹800, discount was 20%
Original = 800 / (1 – 0.20) = 800 / 0.80 = ₹1,000
Example: Sale price ₹800, discount was 20%
Original = 800 / (1 – 0.20) = 800 / 0.80 = ₹1,000
3. Calculate Discount Percentage:
Discount% = (Original Price – Sale Price) / Original Price × 100
Example: Original ₹1,000, Sale price ₹750
Discount% = (1,000 – 750) / 1,000 × 100 = 250/1,000 × 100 = 25%
Example: Original ₹1,000, Sale price ₹750
Discount% = (1,000 – 750) / 1,000 × 100 = 250/1,000 × 100 = 25%

How to Calculate Double Discount (Successive Discounts)
Many sales offer double discounts like “20% + 10% off”. These are NOT the same as 30% off. Here is how to calculate:
Step 1: Apply first discount on original price
Step 2: Apply second discount on reduced price
Example: ₹1,000 with 20% + 10% discount
Step 1: ₹1,000 – 20% = ₹800
Step 2: ₹800 – 10% = ₹720
Total saved = ₹280 = 28% off (NOT 30%)
Formula: Net Discount% = D1 + D2 – (D1 × D2/100)
= 20 + 10 – (20×10/100) = 30 – 2 = 28%
Step 2: Apply second discount on reduced price
Example: ₹1,000 with 20% + 10% discount
Step 1: ₹1,000 – 20% = ₹800
Step 2: ₹800 – 10% = ₹720
Total saved = ₹280 = 28% off (NOT 30%)
Formula: Net Discount% = D1 + D2 – (D1 × D2/100)
= 20 + 10 – (20×10/100) = 30 – 2 = 28%
Common Double Discount Results:
| First Discount | Second Discount | Actual Total Discount | You Think It Is |
|---|---|---|---|
| 10% + 10% | 10% | 19% | 20% — Wrong! |
| 20% + 10% | 10% | 28% | 30% — Wrong! |
| 30% + 20% | 20% | 44% | 50% — Wrong! |
| 50% + 50% | 50% | 75% | 100% — Wrong! |
| 20% + 20% | 20% | 36% | 40% — Wrong! |
Frequently Asked Questions – Discount Calculator
How to calculate discount percentage?
Discount% = (Original Price – Sale Price) / Original Price × 100. Example: MRP ₹1,000, Sale price ₹750. Discount% = (1000-750)/1000 × 100 = 25%. Use Mode 3 of our calculator above for instant results.
How to calculate price after 20% discount?
Final Price = Original Price × (1 – 20/100) = Original × 0.80. Example: ₹1,500 after 20% discount = 1,500 × 0.80 = ₹1,200. You save ₹300.
How to find original price from discounted price?
Original Price = Sale Price / (1 – Discount%/100). Example: Sale price ₹850, discount 15%. Original = 850 / (1 – 0.15) = 850 / 0.85 = ₹1,000. Use Mode 2 of our calculator above.
Is 20% + 10% discount equal to 30% discount?
No! 20% + 10% successive discount = only 28% total discount, not 30%. The second discount applies to the already-reduced price. Formula: Net = D1 + D2 – (D1×D2/100) = 20+10-2 = 28%. Retailers use successive discounts to make offers appear higher than they are.
How to calculate discount on GST included price?
First remove GST from MRP using our GST Calculator, then apply discount on the base price. Or apply discount directly on MRP — the GST component reduces proportionally. Example: MRP ₹1,180 (includes 18% GST), 20% off = ₹944 final price.
