CAC to LTV Ratio Calculator

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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.

Q: 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+.

Q: 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.

Calculate your LTV to CAC ratio - the most important unit economics metric for SaaS businesses.

The LTV:CAC ratio compares the total value a customer generates over their lifetime to the cost of acquiring them. It is the single most important unit economics metric for SaaS businesses. A ratio of 3:1 is the industry standard for a healthy business - meaning each customer generates three times what it costs to acquire them. Below 1:1 means you're spending more to acquire customers than they're worth. Above 5:1 suggests you may be under-investing in growth. This calculator gives you a quick health check on your unit economics.

How to Use This Calculator

Enter your average Customer Lifetime Value (LTV) and Customer Acquisition Cost (CAC).
The calculator will compute your LTV:CAC ratio.
Use it to evaluate overall business health or compare different customer segments and channels..

Formula & Worked Example

LTV:CAC Ratio = LTV ÷ CAC:

Example: LTV = $3,000, CAC = $1,000.

Ratio = $3,000 ÷ $1,000 = 3.0.

A ratio of 3.0 means each customer generates 3x their acquisition cost in lifetime value.

A ratio of 1.0 is break-even; above 3.0 is healthy..

Industry Benchmarks

Industry standard for SaaS is 3:1. Below 1:1 is unsustainable - you lose money on every customer. Above 5:1 may indicate under-investment in growth. According to SaaS Capital, the median private SaaS company has an LTV:CAC ratio of 3.2. Top-quartile companies achieve 5.0+ while still growing rapidly.
