Unit economics are the direct revenues and costs associated with a single unit of your business, usually one customer. The core measures are customer lifetime value and customer acquisition cost. Healthy unit economics mean each customer generates more value than they cost, so growth makes the business stronger, not weaker.

Unit economics answer one question: does growing make you money or lose it faster? If the math on a single customer does not work, scaling marketing only scales the problem. Get LTV, CAC, payback, and margin right on one customer before you pour budget into acquiring thousands.

Example:

 One customer: LTV $18,000, CAC $6,000, payback 6 months, 60% margin. The unit is profitable, so acquiring more is worth doing.

What are the main unit economics metrics?

 Customer lifetime value, customer acquisition cost, the LTV: CAC ratio, payback period, and gross margin. Together, they show whether each customer is profitable.

Why do unit economics matter before scaling?

 If a single customer is unprofitable, growth multiplies the loss. Sound unit economics ensure scale improves the business rather than draining it.
