Thanks for the feedback!
Enter the original price and the discount percentage, and this discount calculator shows the final price you pay and how much you save. It is meant for quick checks while shopping, whether the tag says 25% off in a Diwali sale or 40% off during an online sale weekend.
How the sale price is worked out
The saving is price × discount ÷ 100, and the final price is the original price minus that saving, which is the same as price × (1 − discount ÷ 100). With the placeholder values, ₹999 at 25% off:
- Saving: 999 × 25 ÷ 100 = ₹249.75
- Final price: 999 − 249.75 = ₹749.25
The result box shows the final price in large type, then "You save" and the discount percentage you entered.
Stacked offers are not simply added
"40% off plus an extra 10%" sounds like 50%, but the second discount applies to the already reduced price. On a ₹2,499 pair of shoes, 40% off leaves ₹1,499.40; a further 10% off that leaves ₹1,349.46. The total saving is ₹1,149.54, which is 46%, not 50%. To reproduce it here, calculate once, then enter the new price as the original price for the second discount. The general rule is 1 − (1 − a) × (1 − b):
| Offers | Real total discount |
|---|---|
| 40% + 10% | 46% |
| 50% + 20% | 60% |
| 20% + 20% | 36% |
Reading Indian price tags correctly
- MRP already includes GST under India's packaged-goods rules, so a discount on MRP needs no tax added at the till.
- Card offers are often capped. "10% instant discount up to ₹1,500" on a ₹20,000 phone gives ₹1,500, not ₹2,000, which is an effective 7.5%.
- Multi-buy deals: "buy 1 get 1 free" is 50% off per item and "buy 2 get 1 free" is 33.33%, but only if you actually want every item.
- Check the starting price. A big percentage off an inflated "original" price can still be a poor deal, so compare the final price with other sellers.
Working backwards
To find the discount percentage from two prices, divide the difference by the original price: a kurta cut from ₹1,999 to ₹1,299 is 700 ÷ 1,999 = 35.02% off. The Percentage Change Calculator does this in one step. To recover the original price from a sale price, divide by (1 − discount ÷ 100): ₹749.25 ÷ 0.75 = ₹999.
This page handles percentage discounts only. For a flat coupon such as ₹200 off, subtract it directly, and remember that it is worth more on a cheap item than on an expensive one. Sellers planning a sale can check what a discount does to their margin with the Profit Margin Calculator.
