How to set the inputs honestly.

Cost per lead: $2 is what the newsletter case actually delivered, but it varies. If your product appeals to a narrower niche, assume more. A dedicated subreddit (the $5,000 tier) is what made that volume possible.

Lifetime value per signup: don't use first-month revenue. Multiply your average monthly revenue per customer by how long they typically stay — even a conservative number changes the math fast at $9 vs $1.

The spend: engagements run $3,000–$5,000 per month over 3 months, so a realistic range is $9,000–$15,000.
