CAC vs. LTV: The Golden Ratio for Startups

Understanding the Relationship

While CAC tells you how much it costs to get a customer, Lifetime Value (LTV) tells you how much revenue that customer will generate over their relationship with your business.

The 3:1 Golden Ratio

A widely accepted benchmark in the SaaS and startup world is an LTV:CAC ratio of 3:1. This means a customer should bring in three times the amount it cost to acquire them.

**1:1 Ratio:** You are losing money.

**3:1 Ratio:** You have a healthy, sustainable business model.

**5:1 Ratio or Higher:** You might be under-investing in marketing and missing out on growth opportunities.

How to Improve Your Ratio

You can improve this ratio by either decreasing your CAC (optimizing marketing) or increasing your LTV (upselling, cross-selling, and reducing churn).
