Trial-to-Paid Conversion Rate

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 ~25% (Lincoln Murphy’s rule of thumb for no-credit-card trials). Below 15% suggests users aren't reaching value within the trial period; well above it, verify you're not filtering out valuable users with too-complex signup.
• Opt-out trials: Target ~60% (credit-card-required trials). 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.
