What is a good LTV:CAC ratio?

3:1 is the standard benchmark for healthy SaaS unit economics. Below 1:1 means you lose money on every customer. Between 1:1 and 3:1 is acceptable but watch your payback period. Above 5:1 may indicate you are underinvesting in growth and leaving market share on the table.

How do I improve my LTV:CAC ratio?

Two levers: increase LTV or decrease CAC. To increase LTV, reduce churn, increase ARPU through upsells, or improve gross margins. To decrease CAC, optimize conversion rates, improve targeting, or invest in organic/referral channels that have lower acquisition costs.

Understanding the LTV:CAC Ratio

The LTV:CAC ratio tells you whether your customer acquisition is sustainable. It compares how much a customer is worth over their lifetime (LTV) against how much it costs to acquire them (CAC). A 3:1 ratio is the gold standard. Read our LTV:CAC metric guide for detailed benchmarks.
