Customer Lifetime Value (CLV / LTV)

Customer Lifetime Value (CLV or LTV) estimates the total net revenue a customer will generate from the moment they sign up until they churn. It is one of the most important financial metrics for subscription and recurring-revenue businesses because it determines how much you can afford to spend acquiring a customer while remaining profitable.

The simplest formula divides average revenue per user (ARPU) by churn rate. More sophisticated models factor in gross margin, discount rates, expansion revenue, and contraction revenue to arrive at a net present value.

CLV is most powerful when compared against Customer Acquisition Cost (CAC). A healthy SaaS business typically targets a CLV:CAC ratio of 3:1 or higher, meaning each customer generates at least three times what it cost to acquire them.

Improving CLV is often more cost-effective than acquiring new customers. Tactics include reducing churn, increasing upsell and cross-sell revenue, improving onboarding to accelerate time-to-value, and investing in customer success programs.
