What's the difference between LTV and CLV, and which one matters for SaaS board reporting?

## Brief
LTV (lifetime value) is predictive; CLV (customer lifetime value) is historical. Board cares about LTV upside via retention and expansion.

## Detail

SaaS terminology conflates these metrics, but they drive different board conversations:

**LTV (Lifetime Value)** = predictive model
- Assumes future cohort performance based on observed cohorts
- Formula: `ARPU × (1/(1-retention%)) ÷ (1-discount_rate)`
- Shows what you **expect to earn** if retention/NRR trends hold
- Used to model unit economics sustainability

**CLV (Customer Lifetime Value)** = historical backward-look
- Sum of **actual** margin contributed by a customer from signup to churn
- Real dollars received, not modeled
- Useful for post-mortem and cohort appraisals

For **board reporting**, LTV matters more because it drives investment decisions. SaaStr benchmarks suggest mature SaaS targets **LTV:CAC > 3:1**. If CAC is **$10K** and LTV is **$30K**, you've proven efficient unit economics at scale.

Bridge Group data shows enterprise SaaS achieves:
- **LTV:CAC 4-5:1** for companies with >85% NRR
- **LTV:CAC 2.5-3:1** for 0-20% net new growth

**Operator moves**: 
- Track both in your metrics tier (LTV forward, CLV backward)
- Present LTV to board as efficiency proof; show holdback-adjusted LTV for deals with holdback clauses
- Flag if LTV:CAC is trending below 2.5:1; investigate churn or CAC inflation
