CAC payback period

How many months a customer takes to repay what you spent winning them.

Acquisition cost divided by monthly gross profit per customer. A ₦60,000 CAC against ₦10,000 monthly gross profit is a six-month payback.

This matters more than the LTV to CAC ratio when money is tight, because it answers a cash question rather than a profit question: how long is your money tied up before it comes back and can be spent again.

A company with twelve months of runway and an eighteen-month payback cannot fund its own growth. That is a real constraint, not a rounding error, and it is one of the first things a careful investor works out for themselves.
