Why a Single CAC Number Can Mislead Your Strategy
Many companies calculate a blended CAC (Customer Acquisition Cost) across all segments. For example:
- Overall CAC: $12,000
- SMB CAC: $6,000
- Mid-market CAC: $12,000
- Enterprise CAC: $24,000
If you plan using only the blended number, you risk over-investing in expensive segments and under-investing in profitable ones.
Segment-Specific CAC: The Right Approach
To optimize growth, you need to measure CAC by segment rather than using a single average. This allows you to:
- Calculate payback period by segment:
- Formula: CAC ÷ Monthly Margin (adjusted for churn)
- Identify which segments deliver fast payback and strong economics
- Decide strategically where to invest in growth
Example: Segment Economics in Practice
Consider this scenario:
- SMB: 2-month payback
- Enterprise: 20-month payback
- Retention is similar across segments
Implications:
- SMB is highly efficient; prioritize acquisition here
- Enterprise is slow to pay back; be selective in chasing deals
Most teams skip this analysis. They rely on the blended CAC ($12K), leading to:
- A customer mix skewed toward expensive, slow-payback segments
- Weak unit economics
- Frustration when revenue grows but profitability lags
