LTV to CAC Ratio

ConceptualMetrics

Definition

LTV to CAC Ratio: The LTV to CAC ratio compares customer lifetime value to the cost of acquiring that customer. A ratio of 3:1 or higher is generally considered healthy for SaaS businesses, meaning you earn $3 for every $1 spent on acquisition. This ratio helps evaluate the efficiency of growth investments.

Example Usage

β€œOur LTV:CAC improved from 2:1 to 4:1 after we focused on higher-value customer segments.”

Common Misconceptions

Higher is always better. Very high ratios might mean you're underinvesting in growth.
3:1 is a hard rule. The right ratio depends on your business model and growth stage.
LTV:CAC is the only efficiency metric. CAC payback period matters for cash flow.
