Discount Calculator
Planning a purchase during a sale? Enter the MRP and discount to see the final price and your savings. It handles "extra 10% off" successive discounts too, and can work out the discount percentage from the MRP and sale price.
Step-by-step solution
- Discount 1 = 30% of ₹1,499 = ₹449.7
- Price after discount 1 = ₹1,499 − ₹449.7 = ₹1,049.3
- You save ₹449.7 (30% off MRP).
How to use the discount calculator
- Choose "Final price after discount" or "Find discount %".
- Enter the MRP (marked price) and either the discount % or the price you are paying.
- Add an optional second discount to see the effective single discount of offers like "20% + extra 10% off".
Formulas
| Discount | MRP × Discount% ÷ 100 |
|---|---|
| Final price | MRP × (1 − Discount%/100) |
| Discount % | (MRP − SP) ÷ MRP × 100 |
| Two successive discounts a% and b% | a + b − (a × b ÷ 100)This is the equivalent single discount. |
Solved examples
Example 1: A shirt with MRP ₹1,499 is on 30% off. What will you pay?
- Discount = 1,499 × 30 ÷ 100 = ₹449.70
- Final price = 1,499 − 449.70
Answer: ₹1,049.30
Example 2: A laptop is offered at 20% off plus an extra 10% bank discount. What is the effective discount?
- Effective = 20 + 10 − (20 × 10 ÷ 100)
- = 30 − 2
Answer: 28% (not 30%)
Example 3: Shoes marked ₹2,000 are sold for ₹1,500. What is the discount %?
- Discount = 2,000 − 1,500 = ₹500
- Discount % = (500 ÷ 2,000) × 100
Answer: 25%
Why "20% + 10%" is not 30% off
When a store offers an extra discount, the second discount is applied to the already reduced price, not to the MRP. On a ₹1,000 item, 20% off brings it to ₹800, and an extra 10% off ₹800 is only ₹80 — so you pay ₹720, a total saving of 28%.
This is exactly how successive discount questions are framed in SSC and banking exams. The shortcut a + b − ab/100 gives the answer in one step.
Discount vs. marked price vs. cost price
Discount is always calculated on the marked price (MRP or list price). Profit or loss, on the other hand, is calculated on the cost price. Many exam questions combine both: a trader marks goods above cost, then gives a discount, and you must find the final profit %.

Frequently asked questions
How do I calculate the discount percentage?
Subtract the sale price from the MRP to get the discount, divide by the MRP and multiply by 100. For ₹2,000 reduced to ₹1,500, the discount is 500 ÷ 2,000 × 100 = 25%.
How are two successive discounts calculated?
Apply the first discount to the MRP, then apply the second discount to the reduced price. The equivalent single discount is a + b − (a × b ÷ 100). For 20% and 10%, that is 28%.
Is GST added before or after the discount?
In India, GST is generally charged on the transaction value after a discount shown on the invoice. MRP printed on packaged goods already includes GST.
What is the difference between MRP and selling price?
MRP (maximum retail price) is the highest price a seller can legally charge. The selling price is what you actually pay after any discount.
Does the order of successive discounts matter?
No. 20% followed by 10% gives the same final price as 10% followed by 20%, because multiplication is commutative: 0.8 × 0.9 = 0.9 × 0.8.
