About this calculator
Enter the price and the discount the way it is shown to you. The calculator gives the final price, how much you save, and the real total discount, which is often less than the two percentages added together.
How to use it
- Enter the original price or MRP.
- Choose whether the discount is a percentage or a rupee amount, and enter it.
- If there is an extra discount on top, such as a bank offer, enter it as a percentage.
- Read what you pay, what you save and the real total discount.
The formula
- Price
- the original price or MRP
- d₁
- the first discount in percent
- d₂
- any extra discount in percent, applied to the already-reduced price (0 if none)
Worked example
₹2,499 with “40% + 10% off”
- After 40% off: 2,499 × 0.60 = ₹1,499.40.
- After a further 10% off: 1,499.40 × 0.90 = ₹1,349.46.
- You save ₹1,149.54, which is 46% of the price, not 50%.
What the result means
The total discount line is the honest number to compare offers with. Two discounts stacked one after the other always add up to less than their sum, because the second one applies to a smaller price.
MRP in India already includes GST, so the price you pay after discount also includes tax.
Assumptions
- Discounts apply to the full price shown.
- An extra discount applies after the first discount.
Limitations
- Delivery charges, convenience fees and caps such as “up to ₹500 off” are not included. A capped bank discount may save less than its percentage suggests.
- Results are rounded to the paisa.
Frequently asked questions
Is 40% + 10% the same as 50% off?
No. The 10% applies to the price after the first discount, so together they make 46% off, not 50%.
How do I calculate the discount percentage from two prices?
Divide the amount saved by the original price and multiply by 100. On this calculator, choose “Rupees off” and enter the difference; the total discount line shows the percentage.
Is the discount on the MRP before or after GST?
The MRP printed in India includes GST, and retail discounts are applied to that price, so the final price still includes tax.
