Understanding LTV

The Basic Formula

LTV = ARPU × (1 / Monthly Churn Rate)

If you charge $10/month and 10% of users churn monthly, each user is worth $10 × 10 = $100 on average.

Why Net LTV Matters

Apple and Google take 30% in year one (15% after, or 15% flat for Small Business Program). Your net LTV is what actually hits your bank account - that's what you should compare against CPA.

Annual vs Monthly

Annual subscribers have much lower effective churn (they've pre-committed). A healthy mix of annual subscribers dramatically improves LTV. Push annual plans on your paywall!
