The fundamentals
Freemium vs. paid-only — the core trade-offs
Both models work. The difference is in your product's fit for each — specifically your customer acquisition economics, your product's time-to-value, and whether free users make your product better or just more expensive to run.
Free tier + paid plans
- Lower CAC — acquisition is partly viral/organic
- Massive top-of-funnel from free users
- Product-led growth motion possible
- Users evaluate before paying — reduces sales friction
- High cost to serve free users at scale
- Free tier can cannibalise paid if too generous
- Conversion rates are typically 2–5% (often lower)
- Longer payback period due to acquisition investment
Trial or paid from day one
- Every user is a paying customer — no subsidised non-customers
- Faster payback period and cleaner unit economics
- Easier to forecast revenue
- Natural filter for serious buyers
- Higher barrier to product adoption
- Slower top-of-funnel growth without viral mechanism
- Higher CAC — all acquisition requires spend
- No product-led distribution path
The decision framework
8 questions to decide which model fits your product
Answer these 8 questions honestly. If you score 5 or more "Yes" answers, freemium is worth seriously considering. If fewer than 4, start paid.
Data
Freemium benchmarks you should know
Before committing to freemium, understand what realistic outcomes look like. Most founders overestimate conversion rates and underestimate the cost of serving free users.
| Metric | B2B SaaS average | Top quartile | Note |
|---|---|---|---|
| Free-to-paid conversion | 2–4% | 5–8% | Below 2% = free tier is too generous or the upgrade value is unclear |
| Time to conversion | 30–90 days | 7–30 days | Longer conversion = higher support and infrastructure cost pre-revenue |
| CAC vs. paid-only model | 40–60% lower | 70%+ lower | The core advantage of freemium — when it works, acquisition is cheap |
| Churn (from freemium-converted) | 15–25% lower | 30%+ lower | Free-to-paid converts are more activated and churn less than direct-paid |
| % of revenue from top 20% of customers | 70–80% | — | Freemium creates long tails; revenue is concentrated in a small % of users |
Key insight: The best-performing freemium products in SaaS — Slack, Figma, Notion, Loom, Calendly — all have one thing in common: the free tier itself creates word-of-mouth. Every Loom video shared, every Calendly link sent, every Notion page published is an acquisition event. If your product doesn't have this embedded sharing mechanism, freemium is significantly harder to justify.
