A business can grow its sales every month and still be marching toward closure — if every unit it sells loses money. Unit economics is the discipline of checking profitability at the level of one order, one customer, one plate or one kilogram, before scaling. It is the difference between "we are busy" and "we are profitable". Here is how to compute and use it, with simple Indian examples.
The core: contribution margin per unit
Take one unit of whatever you sell. Subtract every cost that occurs because that unit was sold — raw material, packaging, delivery commission, payment gateway fees, incentive to staff if volume-linked. What remains is the contribution margin: the money each unit contributes toward rent, salaries and profit. A cloud kitchen selling a ₹300 meal might pay ₹105 for ingredients, ₹25 packaging, ₹75 aggregator commission and ₹6 gateway fees — leaving ₹89, a 30% contribution margin.
Why averages lie
Compute contribution item by item, not on total revenue. Menus, catalogues and service lists usually contain a few heroes subsidising many losers. A bakery may find its breads earn 15% while custom cakes earn 55% — meaning growth in breads makes it poorer per hour of oven time. Until you see margin per item, you cannot decide what to promote, reprice or drop.
Customer acquisition cost and payback
- CAC = total marketing spend ÷ new customers acquired in the period
- If ₹15,000 of ads brought 100 first orders, CAC is ₹150
- Payback: with ₹89 contribution per order, a ₹150 CAC is recovered in the second order
- If most customers never return, your real CAC must be recovered in one order — which changes what you can afford to spend
This is why repeat rate is the most important number in most consumer businesses. High repeat rates let you spend confidently on acquisition; poor ones make every discount-funded "growth" a slow leak.
The break-even bridge
Unit economics connects directly to your survival number: monthly fixed costs ÷ contribution per unit = units needed to break even. Fixed costs of ₹1,80,000 and ₹89 per order means roughly 2,023 orders a month, or 67 a day. Now every daily sales report answers a precise question — are we above or below 67? That clarity changes how a team behaves.
A 10% discount does not cost 10% of profit — it comes entirely out of contribution. If margin is ₹89 on ₹300, a ₹30 discount removes a third of the unit's profit. Volume must rise ~50% just to stand still. Run this math before every offer.
Improving the numbers, lever by lever
- Price: small increases flow straight to contribution; test 3–5% on your least price-sensitive items
- Raw material: negotiate rates quarterly, control portions and wastage — a 2% food-cost saving is pure margin
- Mix: promote high-margin items visibly; redesign menus and bundles around them
- Channel: own-channel orders (WhatsApp, website, walk-in) avoid aggregator commission — shifting even 20% of orders is transformative
- Delivery and packaging: renegotiate as volumes grow; costs set at launch are rarely revisited
How Aidwish helps
Aidwish builds unit-economics models for clients during setup and reviews them monthly in its profitability stage — item-level margins, CAC and payback, break-even tracking and pricing decisions, so growth adds profit instead of just activity.
