Unit Economics: Does One Sale Make Money?
Strip a business to a single transaction and ask if even that is profitable.
Unit economics zooms all the way in: forget the whole company, does a SINGLE sale or customer make money once you count the costs to serve it? It’s the truth serum for fashionable, fast-growing businesses.
ExampleA deliveryBuying shares to hold in your demat beyond the day. app charges ₹50 per order but pays ₹40 to the rider, ₹15 in discounts and ₹10 in supportPrice zones where buying (support) or selling (resistance) tends to dominate. — losing ₹15 on every order. Growth makes it lose money FASTER. Until the unit is profitable, scale is a trap, not a triumph.
Many hyped “growth” companies are selling rupees for 80 paise — the more they sell, the more they lose. Always ask whether a single unit is profitable BEFORE celebrating revenue growth. Profitable unit + growth = a machine; unprofitable unit + growth = a bonfire of cash.
Key takeawayUnit economics asks if one sale/customer is profitable after all costs to serve it. Growth only creates value when the underlying unit already makes money.
