Overview
Freemium offers a genuinely useful free tier to acquire users at scale, then converts a minority to paid plans with premium features, capacity, or convenience. The free tier is the marketing budget: it spreads the product cheaply and lets people experience value before paying.
The economics only work because software's marginal cost is near zero — serving a free user costs almost nothing — and because a small paying fraction, multiplied by a very large base, covers everyone. The art is drawing the free/paid line so the free tier is useful enough to attract but limited enough to convert.
How it works
Offer a free tier valuable enough to attract a large user base.
Reserve premium features, capacity or support for paying tiers.
Convert a small percentage to paid; the free base is the acquisition engine.

When it works
- Marginal cost of serving a free user is near zero.
- The free tier showcases real value and drives word-of-mouth.
- There's a clear reason for heavy users to upgrade.
When it fails
- Free users cost real money to serve, so scale burns cash.
- The free tier is too generous — nobody needs to pay.
- Or too stingy — nobody sticks around to convert.
Frequently asked questions
What conversion rate is normal?
Often just a few percent of free users pay — which is fine, because the free base is huge and cheap to serve. The model relies on scale, not a high conversion rate.
Where should the free/paid line go?
Free must be useful enough to attract and retain, but leave a clear, valuable reason — capacity, features, support — for committed users to upgrade.
