Freemium vs. Opt-In vs. Opt-Out: Modeling the Same Launch Three Ways
Objective: Given the lesson's real visitor-to-signup and signup-to-paid benchmarks, calculate how many paying customers each of the three acquisition models produces from the same 50,000 monthly visitors, and recommend a model for a new seller-analytics add-on.
Flipkart's Seller Hub team wants to launch a paid analytics add-on for third-party sellers and is deciding between freemium, an opt-in trial, and an opt-out (card-required) trial. You have 50,000 monthly seller-portal visitors and the industry benchmarks from this lesson.
Apply the lesson's visitor-signup rates and signup-to-paid conversion rates to each model, calculate paying customers per month, and recommend a model with the tradeoff stated explicitly.

The process
1 step
Step 01 of 01
The lesson cites: opt-in trials convert 8.9% of trial signups to paid but only 7.8% of visitors sign up. Opt-out trials convert 49.9% of signups but only 2.4% of visitors sign up (card requirement filters hard at the door). Freemium converts 3-5% of a much larger signup pool to paid over time.
From 50,000 monthly visitors, which of the three models produces the most paying customers this month, and which produces the most total signed-up users (future upgrade candidates)?
Procedure
- Freemium: assume a 10% visitor-to-signup rate (low friction, no card) x 50,000 = 5,000 signups; apply 3% freemium-to-paid = 150 paying customers this month.
- Opt-in trial: 7.8% visitor-to-signup x 50,000 = 3,900 signups; apply 8.9% trial-to-paid = ~347 paying customers.
- Opt-out trial: 2.4% visitor-to-signup x 50,000 = 1,200 signups; apply 49.9% trial-to-paid = ~599 paying customers.
- Compare total signed-up users too: freemium leaves 4,850 unconverted-but-active free users; opt-out leaves only ~601 non-converters, most of whom never signed up at all.
- Weigh cost-to-serve: an analytics add-on with real compute cost per seller favors the model with fewer non-paying users on the infrastructure bill.
50,000 visitors, three models compared Freemium: 5,000 signups x 3% = 150 paying/mo. 4,850 free users still on infra. Opt-in trial: 3,900 signups x 8.9% = ~347 paying/mo. 3,553 lapsed trials, off infra after 14 days. Opt-out trial: 1,200 signups x 49.9% = ~599 paying/mo. Smallest funnel, highest yield per signup.
Healthy
The opt-out trial produces the most paying customers per visitor this month, and the fewest non-paying users sitting on infrastructure.
Unhealthy
Picking freemium by default because 'more signups feels safer,' without running the actual math on paying-customer yield.
What this means
For a seller tool with real per-seller compute cost (analytics queries against live order data), the opt-out trial's card-required filter produces more revenue per visitor and less unpaid infrastructure load than freemium.
So what do I do about it?
| Symptom | Action | Effort |
|---|---|---|
| Team defaults to freemium because it 'feels more generous' to sellers | Run the visitor-to-paying math before choosing; recommend opt-out trial given the compute cost per active seller | 30 min |
Final deliverable
A one-page recommendation memo: paying-customer count per model, non-paying-user infrastructure load per model, and a stated recommendation with the tradeoff named explicitly.

Sea Limited, Shopee seller-tools launch memo (excerpt) Model comparison at 80,000 monthly visitors: Freemium: 480 paying/mo, 7,600 free users on infra. Opt-out trial: 940 paying/mo, 900 total signups. Recommendation: opt-out trial. Real-time inventory sync has non-trivial compute cost per active seller; the smaller, higher-intent funnel wins on unit economics.
Success criteria
You're done when you can:
- Correctly applies both the visitor-to-signup and signup-to-paid rates for all three models
- States a recommendation with an explicit tradeoff, not just the model with the highest paying-customer count
