Ehsan's Insight
A 5% monthly churn rate sounds small. It means you lose half your customers every year. The compounding is brutal and most founders do not internalize it until they build a churn model in a spreadsheet and watch the numbers. At 5% monthly churn, you need to acquire 50 new customers every month just to maintain 1,000 customers. At 2% monthly churn, you only need 20. That difference — 30 fewer customers per month to acquire — at $500 CAC is $180K per year in savings. Reducing churn from 5% to 2% is almost always cheaper than acquiring the extra customers to offset it. Yet 90% of growth budgets go to acquisition and 10% go to retention. The allocation should be closer to 50/50.
