Newsletter Unit Economics: Churn, LTV & the Paid Substack Math

A paid newsletter with 1,000 subscribers at $10/month is $10,000 MRR -- until churn enters. At 5% monthly churn (typical for paid newsletters), you lose 50 subscribers a month and must acquire 50 just to stand still. Average subscriber lifetime: 1/0.05 = 20 months. Lifetime value: $10 x 20 = $200 per subscriber (minus Substack 10% + Stripe ~3%). The entire business is this equation: LTV vs CAC. If acquiring a subscriber costs $30 and LTV is $174 net, the machine works. If CAC is $80, it bleeds.

Churn is not uniform -- it has a shape. Month-1 churn runs 8-15% (buyer remorse, wrong expectations); months 2-6 settle to 4-7%; long-tenured subscribers churn at 1-3%. This means growth compounds asymmetrically: reducing month-1 churn from 12% to 8% is worth more than any acquisition channel, because every saved subscriber pays for 20 months. The levers: onboarding sequences (the first 3 emails determine retention more than the next 30), expectation-setting at signup (what cadence? what topics? -- mismatch drives month-1 exits), and annual plans (annual subscribers churn ~40-60% less; push annual with 2-months-free pricing).

Free-to-paid conversion is the other engine. Typical: 5-10% of free list converts to paid. A 20,000 free list at 7% = 1,400 paid = $14,000 MRR at $10. Growing the free list is usually cheaper than direct paid acquisition -- lead magnets, cross-promotions, and recommendations (Substack network effects are real: 20-40% of paid growth for many writers comes from other newsletters recommendations). The calculator models free list size, conversion %, churn curve, pricing, and platform fees into MRR, LTV, and months-to-$10k -- the three numbers that determine if this is a business or a hobby.

Pricing psychology matters more than writers expect. $5/mo vs $10/mo rarely halves conversion -- price elasticity in newsletters is low because the decision is about the writer, not the price. Annual at $100 (vs $120 monthly) pushes commitment and cuts churn nearly in half. Founding-member tiers ($200+/yr) monetize superfans at 5-10x with minimal extra work. Test pricing up, not down: almost no newsletter regrets charging more; many regret anchoring at $5 and trying to raise later against subscriber revolt.
