Growth metric
CAC Payback Period
Formula
CAC ÷ monthly gross profit per customer
Worked example
You spent ₹4,00,000 last month across ads, tools and sales time, and acquired 80 customers. That's ₹5,000 per customer. If gross profit per customer is ₹1,250 a month, you get the money back in four months.
Why it matters
It tells you whether growth is affordable at your current margin and runway — before you scale spend.
When it can mislead
Blended numbers hide the truth. One organic channel can make a failing paid channel look healthy. Segment by source before deciding.
