FAQ & key takeaways

How to read this metric

What it measures

The LTV:CAC ratio compares the Customer Lifetime Value (LTV) to the Customer Acquisition Cost (CAC). It is a vital metric that indicates whether your customer acquisition strategy is sustainable and profitable in the long run.

Why it matters

This ratio tells you whether you are spending the right amount to acquire new customers. A ratio below 1 means you are losing money on every customer. A ratio of 3 is often cited as the target for SaaS businesses, indicating a good balance between the value customers bring and the cost to acquire them. A ratio much higher than 3 might suggest you should spend more on acquisition to grow faster.

How to improve LTV:CAC Ratio

  1. Increase LTV: Improve customer retention, increase average purchase value, or lengthen customer lifespan.
  2. Decrease CAC: Optimize marketing and sales efficiency, refine audience targeting, or improve conversion rates.
  3. Combination: Simultaneously work to increase LTV and decrease CAC for maximum impact on the ratio.
