How this tool works

Freemium sounds simple — free users convert to paid — but the math is brutal. A SaaS with 3% conversion rate (good) and $50 ARPU needs 67 paid users to make $3,350/month — that requires 2,233 free users. To get those 2,233 free signups at 5% visitor conversion, you need 44,667 monthly visits.

This calculator inverts the funnel: input your MRR goal and it tells you exactly how many paid users, free users and monthly visits you need. Useful to validate if your current acquisition channel can sustain your goal or if you need to change pricing/conversion.

Frequently asked questions

What % free → paid is realistic?
SaaS average: 2–5%. Best-in-class (Slack, Notion): 8–10%. If you're below 1%, your paywall is misconfigured or pricing is high.
And visitor → signup conversion?
Bottom-up B2B SaaS: 3–8%. Consumer freemium products (Spotify free): 15–25%. Totally depends on onboarding friction.
What do I optimize first?
Optimize paid conversion first (highest leverage). Then pricing/ARPU. Traffic last — it's the most expensive to move.
Is freemium always worth it?
No. If your CAC is high and ARPU low, freemium subsidizes users who'll never pay. Better: 14-day trial with card required.
