Customer Lifetime Value (CLV)

Customer Lifetime Value (CLV, sometimes LTV) is the total revenue you can expect from a customer over the entire duration of their relationship with your business. At its simplest: ARPA multiplied by average customer lifespan. If a customer pays $2K/month and stays for 36 months on average, the CLV is $72K.

CLV matters in GTM operations because it sets the ceiling on what you can afford to spend acquiring and retaining customers. A $72K CLV means a $20K CAC might be acceptable. A $15K CLV means the same CAC would bankrupt you. Every acquisition and retention investment should be evaluated against the lifetime value it’s expected to generate.

The basic CLV formula (ARPA x customer lifetime) works for quick calculations, but a more accurate approach accounts for gross margin, expansion revenue, and discounts the future cash flows. A customer who expands from $2K to $5K/month over three years has a much higher CLV than one who stays flat — and they’re worth more investment to keep happy.

Segmenting CLV reveals which customers deserve the most attention. Enterprise customers might have 3x the CLV of mid-market customers, which justifies a more expensive, high-touch sales and success motion. Customers acquired through certain channels might have higher CLV because they’re better fits — that data should influence marketing budget allocation.

Two ways to increase CLV: keep customers longer (reduce churn) or increase what they pay over time (drive expansion). Both require investment in customer success, product quality, and account management. Analytics helps you track CLV by segment, cohort, and acquisition channel to understand where your most valuable customers come from.
