Trial-to-Paid Conversion Rate

Percentage of trial users who become paying customers. The moment of truth for your value proposition.

Trial-to-Paid = (Users who converted to paid / Total trial users) × 100%

What it measures

How effectively your trial experience demonstrates enough value to justify payment. This metric is highly sensitive to trial design: opt-out trials (requiring credit card upfront) convert 2-3× higher than opt-in trials, but attract different user types.

What to watch

Opt-in trials: Target 18-25% conversion. Below 15% suggests users aren't reaching value within the trial period. Above 25% is excellent, but verify you're not filtering out potentially valuable users with too-complex signup.
Opt-out trials: Target 49-60% conversion. Below 40% indicates poor activation or value mismatch. Above 60% is best-in-class. Watch for involuntary churn in Month 2 from users who forgot to cancel.

In practice

A project management tool offered 30-day trials with 22% conversion. When they analyzed user behavior, most converters decided within 7 days; non-converters rarely returned after Day 10. They switched to 14-day trials with more aggressive onboarding emails. Conversion rose to 31%: shorter timeline created urgency and focused the team on faster activation.
