What Is Customer Lifetime Value?
Customer Lifetime Value (LTV or CLV) estimates the total revenue or profit a single customer generates over their entire relationship with your business. It is one of the most important metrics for SaaS, e-commerce, and subscription companies because it determines how much you can afford to spend on acquisition, which customer segments are most valuable, and whether your business model is sustainable long-term.
LTV Formulas
Simple LTV = ARPU × Average Customer Lifespan (months)
LTV with Margin = ARPU × Gross Margin % × Lifespan
LTV from Churn = ARPU × Gross Margin / Monthly Churn Rate
Average Lifespan = 1 / Monthly Churn Rate
The LTV to CAC Ratio
The LTV:CAC ratio compares what a customer is worth against what it costs to acquire them. A ratio of 3:1 or higher is considered healthy, meaning each customer generates three times their acquisition cost. Below 1:1 means you are losing money on every customer. This ratio guides marketing budget allocation, channel prioritization, and pricing decisions. Improving retention even slightly can dramatically shift this ratio in your favor.
How to Increase LTV
There are three levers for increasing LTV: raise average revenue per user through upsells and price increases, improve gross margin by reducing cost of delivery, or extend customer lifespan by reducing churn. The most effective approach is reducing churn, because even a 1% improvement in monthly retention compounds over the entire customer relationship. Strong onboarding, proactive customer success, and continuous product improvement all contribute to higher LTV.
