MRP Is Not the Price: How Indian Discount Percentages Are Really Calculated

Maximum Retail Price is a ceiling, not a market price. Under India's Legal Metrology (Packaged Commodities) Rules, a manufacturer must print an MRP on a packaged product and no one may sell above it. Nothing in that law says the MRP has to resemble what the product is worth, what it costs to make, or what a single customer has ever paid.

That one gap is the engine behind almost every eye-catching discount percentage you see online.

How the percentage is actually computed

The formula every platform uses is unremarkable:

discount % = (MRP − selling price) ÷ MRP × 100

Notice what it depends on. The selling price is real — it's the money leaving your account. The MRP is a number the brand typed into a field. Raise the MRP and the discount percentage rises with it, without the price you pay moving a rupee.

A worked example, using the same shirt in both rows:

Same shirt. Same ₹649. The second listing simply had a more ambitious MRP printed on the tag. This is legal, common, and the reason "up to 80% off" banners cluster on categories — fashion, luggage, small kitchenware, no-name electronics accessories — where no buyer has a reference price in their head.

Why some categories can't play this game

Compare that shirt to an iPhone. Apple sets and publishes the MRP, every retailer in the country lists the same number, and buyers know it to the rupee. Inflating it is impossible. So on iPhones you see 8–14% off, and that 8% is worth more real money than an 81% off unbranded shirt.

The pattern generalises cleanly:

• MRP is trustworthy where the brand controls pricing nationally and buyers know the number — phones, laptops, branded appliances, FMCG staples, books.
• MRP is decorative where the seller sets it themselves — marketplace fashion, generic accessories, unbranded home goods, most "combo packs".

A useful rule: the higher the advertised discount percentage, the less you should trust the base it was calculated from. A genuine 65% off a well-known product is rare enough to make news. A 65% off something you've never heard of is Tuesday.

The three MRP tricks worth recognising

1. The MRP that only exists online. Marketplace sellers list their own MRP. Two sellers of the identical SKU can show ₹999 and ₹2,499 as MRP for the same ₹499 item. Whichever prints the bigger number wins the "% off" sort.

2. The pack-size shuffle. A 400 g pack at ₹280 and a 300 g pack at ₹240 with "20% off" on the smaller one. The discounted pack is more expensive per gram. Always divide by the unit — per kg, per litre, per tablet, per ml.

3. The pre-sale markup. The selling price rises for a fortnight, then falls to roughly where it started under a sale banner. The MRP never moved; the reference did. This is the one that catches careful shoppers, because they're checking the right number — just not far enough back. We covered the tells in detail in how to spot a fake sale.

What to compare instead

Stop reading the percentage. Read these four things, in order:

1. The final billed amount after coupon, bank offer, delivery and any platform fee. It's the only number that leaves your account.
2. The same product's price on a second platform. Two tabs, sixty seconds. This defeats an inflated MRP instantly, because a fake reference price doesn't travel across sites.
3. The unit price. Rupees per kilo, per litre, per 100 ml, per tablet. Pack-size games die here.
4. The price 30 days ago. If you don't know it, pull a price history before you decide.

Those four take about a minute together, and they are strictly more informative than every banner on the page.

Is inflated MRP legal?

Printing a high MRP is legal — the law caps what you may charge, not what you may claim as a ceiling. What is not permitted is a misleading advertisement about the discount itself, which falls under the Consumer Protection Act, 2019 and the CCPA's guidelines on misleading advertisements. The Bureau of Indian Standards and CCPA have both moved against "dark patterns" including false urgency and drip pricing.

In practice, enforcement is slow and the incentive to inflate is immediate. Treat the percentage as marketing copy, because that's what it functionally is.

Frequently asked questions

What does MRP actually mean in India? Maximum Retail Price is the highest price at which a packaged product may legally be sold, inclusive of all taxes. It is a legal ceiling set by the manufacturer or packer — not an assessment of value and not a price anyone is required to have charged.

Is it illegal to sell below MRP? No. Selling below MRP is entirely legal and completely routine. Only selling above the printed MRP is prohibited.

Can a seller print any MRP they want? Effectively yes, within the rules on declaration and labelling. There is no legal test of reasonableness for the number itself, which is why marketplace sellers of the same item often display wildly different MRPs.

Why do iPhones only ever show a small discount? Because Apple sets a nationally known MRP that no retailer can inflate. The base is honest, so the percentage looks modest — even when the rupee saving is large.

How do I tell a real discount from an inflated one? Compare the final billed price against a second platform and against the item's own price 30 days ago. If both agree the price genuinely fell, the discount is real regardless of what percentage the banner claims.
