The Chai Stall: Margins and Volume

How a roadside tea stall earns a living on tiny margins per cup by selling in high volume, and what drives its profits.

Almost every street in India has a chai stall. It looks simple, but it’s a lesson in business economics.

The costs (illustrative)

For a stall selling tea at 10 rupees a cup:

Variable costs per cup: milk, tea leaves, sugar, gas and a paper cup, perhaps 4 to 5 rupees.
Fixed costs per month: a small rent or informal fee for the spot, equipment, and perhaps a helper’s wages.

Contribution margin

Each cup contributes around 5 to 6 rupees toward fixed costs and the owner’s income.

Volume is everything

If the stall sells 300 cups a day, contribution is about 1,500 to 1,800 rupees a day. After fixed costs, the owner may earn a modest monthly income. If sales drop to 150 cups, income falls sharply, because fixed costs remain.

Location

Stalls near offices, stations, hospitals or colleges sell far more. The best spots are competitive, and informal payments to secure them can be a hidden cost.

Add-ons

Selling biscuits, snacks or cigarettes adds revenue with little extra cost, raising income per customer.

Price sensitivity

Chai drinkers notice price increases. When milk prices rise, stalls may raise prices by a rupee or two, or use slightly smaller cups.

Key lesson

Low-margin businesses survive on high volume and low fixed costs, making location crucial.

The station stall

A chai seller near a railway station sells 500 cups a day during rush hours. A friend with a similar stall on a quiet street sells 120. Same product, same price, very different incomes, all because of location.

Thinking small margins mean small profits

High volume can turn tiny per-unit margins into a solid income.

Key takeaways

Chai stalls earn small margins per cup.
Volume and location determine income.
Low fixed costs keep the business viable.
Add-on products raise revenue per customer.
