He botches the math. 20% monthly churn means you have to replace your customer base 2.4 times over a year, not 8 times. But the conclusion is the same: CAC > LTV.

I assume his formula (1+monthly_churn)^12 – 1 was based on a misremembering or misunderstanding of annual churn = 1 - (1-monthly_churn)^12.
