What is a good LTV:CAC ratio?

3:1 or higher is healthy. Below 1:1 means you lose money on each customer. Above 5:1 may signal under-investment - you could profitably spend more on acquisition to grow faster.

How do I improve my LTV:CAC ratio?

Increase LTV through better retention, higher pricing, or expansion revenue. Reduce CAC through channel optimization or product-led growth. Both approaches improve the ratio. Use [Baremetrics](https://baremetrics.com?via=saastainednumbers) to track LTV:CAC across customer segments automatically.

Should I calculate LTV:CAC by channel?

Yes. Different channels have dramatically different ratios. Paid ads might have 2:1, while referrals might have 10:1. Channel-level analysis reveals where to invest.

What does a declining LTV:CAC ratio mean?

It means either LTV is decreasing (worse retention, lower pricing) or CAC is increasing (more expensive channels, sales inefficiency). Investigate the root cause.

How does LTV:CAC relate to payback period?

They're complementary. LTV:CAC measures overall return; payback period measures how long to recover CAC. A 3:1 ratio with 6-month payback is healthier than 3:1 with 18-month payback.

Is a very high LTV:CAC always good?

Not necessarily. A 10:1 ratio might mean you're under-investing in growth. If you can profitably acquire customers at a 3:1 ratio, you should spend more to capture market share.

How does LTV:CAC vary by business model?

Enterprise SaaS typically has higher ratios (5:1+) due to longer customer relationships. SMB SaaS often has lower ratios (2-3:1) due to higher churn. Marketplaces may have 10:1+.

What is a healthy LTV:CAC for a new product?

Early-stage products often have ratios below 2:1 while finding product-market fit. The target should be reaching 3:1 within 12-18 months of launch.
