Key Takeaway: Customer lifetime value answers the question that should come before every acquisition spending decision: what is a customer actually worth, over the whole relationship, not just the first sale?

The Formula
Example
Average order value: $60. Purchase frequency: 4 times/year. Average customer lifespan: 3 years.
Compare It Against CAC
A healthy business generally wants CLV to be at least 3x Customer Acquisition Cost. If CAC is $200 and CLV is $720, that's a 3.6x ratio. Healthy. If CAC crept up to $300, the ratio drops to 2.4x, worth investigating before scaling spend further.

Checklist
- Calculate average order value
- Calculate purchase frequency per year
- Estimate average customer lifespan in years
- Multiply the three to get CLV
- Compare CLV against current CAC
- Recalculate periodically as the underlying numbers shift
Common Mistakes
FAQ
What's a healthy CLV-to-CAC ratio?
A commonly cited target is at least 3x. Below that suggests acquisition spend may not be sustainable long-term.
Does CLV change over time?
Yes. It should be recalculated periodically as purchase frequency, order value, and retention rates shift.
What's the biggest lever for raising CLV?
Increasing repeat purchase rate, since it directly extends the average customer lifespan used in the formula.
Should CLV be calculated per customer or as an average?
Both are useful. An average CLV guides overall acquisition budgets, while per-segment CLV can inform different spending on different customer tiers.
