Calculator guide
Understanding Paid Newsletter Unit Economics Calculator
Paid-newsletter economics depend on starting subscribers, acquisition, churn, price, service cost, fixed editorial expense, and the timing of membership change.
Calculation method
How the calculation works
Model paid newsletter membership movement from opening members, new acquisition and churn, then calculate recurring revenue, contribution, acquisition spend, operating profit, break-even membership, and a transparent gross LTV-to-CAC reference. Subtract expected monthly churn from new subscribers, carry the net change across the horizon, and reconcile ending contribution with acquisition and fixed cost.

Worked situations
Practical examples
- New subscribers can exceed churn while profit remains negative because acquisition spend is high.
- A small churn change materially affects gross lifetime value.
- Annual plans improve cash timing but do not eliminate renewal risk.
Better inputs
Useful tips
- Track cohorts by acquisition source and start month.
- Separate gross subscriber count from successfully paid accounts.
- Use contribution after payment, platform, and fulfillment costs.
Before relying on the result
Limitations and common mistakes
- Churn, price, acquisition, and variable cost remain constant.
- Annual plans, refunds, taxes, payment failures, upgrades, and cohort aging are simplified.
- Gross LTV is not a valuation.
Reference

Frequently asked questions
Should free subscribers be included?
Not unless they are intentionally modeled as paid active members.
Is LTV exact?
No. It is a steady-state gross contribution reference.
How should annual plans be handled?
Use a cohort cash-flow model when billing timing matters.
