What is Customer Lifetime Value? CLV Definition and Formula
Customer lifetime value, often shortened to CLV or LTV, is the estimated total revenue or gross profit a customer generates over their relationship with a business. It helps teams understand how much a customer is worth beyond the first purchase or signup.
CLV is especially important for subscription businesses, SaaS products, ecommerce stores, and any company with repeat purchases.
Simple CLV formula
A simple formula is:
CLV = average revenue per customer x average customer lifetime
For a subscription product, teams may use monthly recurring revenue, gross margin, churn rate, and expansion revenue to estimate CLV more accurately.
Why CLV matters
CLV helps answer:
- How much can we spend to acquire a customer?
- Which channels bring high-value customers?
- Which segments retain better?
- Which campaigns create profitable growth?
- Which onboarding steps influence long-term value?
Without CLV, teams may optimize only for cheap signups instead of valuable customers.
CLV and analytics
Analytics connects acquisition source, campaign, product usage, conversion, and revenue. This helps teams compare not only how many customers each channel brings, but how valuable those customers become over time.
