Average member lifetime is roughly 1 divided by your churn rate. At 5% monthly churn, the average member stays about 1 / 0.05 = 20 months. This inverse relationship is why small changes in churn have an outsized effect: cutting churn from 5% to 4% stretches average lifetime from 20 to 25 months, a 25% increase in how long members stay and pay.
Because serving a member has a cost, so only their gross margin actually contributes to profit. Lifetime value on gross margin — revenue per member times gross margin times lifetime — reflects what a member is really worth to the business, and it's the right number to compare against what you spend to acquire one (CAC).
A ready-to-use spreadsheet (Excel & Google Sheets): member lifetime and gross-margin LTV from your churn and pricing, with a view of how retention improvements lift LTV — delivered instantly after checkout. AI-assisted, human-built; not financial advice.
