Quick answer
A big "% off MRP" often means nothing, because MRPs are set high. The Deal Score weighs what matters: the real discount against the price the product usually sells for (40 points), rating and review count (30), seller trust (10), MRP discount (10) and return window and warranty (10). 80 or more is a great deal; under 50, wait for a better price.
How to use this calculator
- Enter the deal price, the price it usually sells for and the MRP.
- Add the rating, number of ratings and seller type.
- Add the return window and warranty to get the score.
Deal Score method
| Factor | Points | Full points when |
|---|---|---|
| Real discount vs usual price | 40 | 25% or more below the usual selling price |
| Rating | 20 | 4.4 stars or more |
| Number of ratings | 10 | 10,000 ratings or more |
| Seller trust | 10 | Brand store or authorised seller |
| Discount vs MRP | 10 | 50% or more below MRP |
| Returns and warranty | 10 | 10-day returns and 12-month warranty |
The score is a guide, not a guarantee. Read the seller's return policy before buying.
Frequently asked questions
Where do I find the usual price?
Check price-history sites or note the price over a few weeks. Without it, use the lowest price you have seen recently.
Why does the MRP discount count so little?
MRPs are often far above real selling prices, so "70% off" is common and means little on its own.
Is the method public?
Yes. The full Deal Score method, with every weight, is published on our Deal Score method page.
