It is 7:30 PM on a Tuesday. You have had a long day. The kitchen is empty except for some onions and leftover dal. Zomato is three taps away. Every Indian family of four navigates this moment dozens of times a month, and the decision made in that moment — multiplied across 30 days — is the difference between spending ₹6,000 and spending ₹25,000 on food.

This article does the maths that most people avoid doing because they suspect it will be uncomfortable. We have built a genuine month-by-month cost model for a family of four in an Indian metro city — covering every meal, every platform fee, every delivery charge, every gas cylinder, every kilo of vegetables — to give you a number you can actually argue with or act on.
