What the New Rule Says
In a significant move to protect consumers and increase transparency, the Central Government has reintroduced standard pack sizes for all major edible oils, including sunflower, mustard, soybean, and palm oil. As of early June 2026, companies were given
a three-month transition period to phase out confusing, non-standard quantities like 850 ml or 910 grams. Now, oils must be sold in prescribed sizes: 200 ml/g, 500 ml/g, 1 litre/kg, 2 litres/kg, and so on, up to 20 litres/kg. This change was made after extensive consultation with industry bodies to end the practice of using odd sizes, which made it difficult for shoppers to compare prices fairly. The goal is to create a level playing field where a 1-litre bottle from one brand can be directly compared to a 1-litre bottle from another.
Why Standard Packs Aren't a Silver Bullet
While standardised packaging is a major improvement, it doesn’t mean all one-litre bottles will have the same price or offer the same value. Several factors still influence the final cost you pay at the counter. Different brands will always have different pricing strategies based on their production costs, marketing expenses, and perceived quality. Furthermore, the type of oil itself is a major price driver; groundnut oil is naturally more expensive than palm oil, for example. Retailers also run their own promotions, offering discounts on specific brands or larger pack sizes. This means a two-litre bottle on sale might be a better deal than two one-litre bottles of the same oil, but not always. Relying on the pack size alone can still lead you to overspend.
Your Best Tool: Calculating the Unit Price
The single most powerful tool for a savvy shopper is the unit price. This is the cost of the product broken down into a standard unit of measurement, such as price per litre, per 100 millilitres, or per kilogram. Calculating it is simple and can be done in seconds on your phone’s calculator. The formula is: Total Price ÷ Total Quantity = Unit Price. For example, if a 5-litre can of sunflower oil costs ₹750, you divide 750 by 5 to get a unit price of ₹150 per litre. If a different brand sells a 2-litre bottle for ₹320, its unit price is ₹160 per litre (320 ÷ 2). In this case, the larger can offers better value. Some packages may already declare the unit sale price, a practice which has been encouraged by regulations to help consumers. Always look for it near the MRP.
Beyond the Cooking Oil Aisle
The principle of checking the unit price isn't just for cooking oil; it’s a crucial habit for all your grocery shopping. This method is essential for comparing prices of items like rice, dals, detergents, biscuits, and snacks, which all come in a variety of pack sizes and are subject to frequent promotional offers. It’s also your best defence against a common industry practice known as “shrinkflation,” where manufacturers reduce the quantity of a product (e.g., from 500g to 450g) while keeping the retail price the same. Without checking the unit price, you might not even notice you're getting less for your money. Making unit price comparison a regular part of your shopping routine empowers you to see past the marketing and identify the true value of what you're buying.
Quick Tips for Smarter Shopping
To ensure you get the most value for your money, keep these simple tips in mind. First, always compare the unit price, not just the sticker price, especially between different brands and sizes. Second, don't automatically assume a larger 'jumbo' pack is cheaper. Do the quick math to confirm. Third, be mindful of discounts. A 10% discount on a more expensive item might still make it costlier per unit than a regularly priced alternative. Finally, look out for multi-buy offers like 'buy-one-get-one-free'. While often a great deal, quickly calculate the unit price based on the total quantity you receive to be certain it’s the best option available on the shelf.
