What is Trial conversion rate?

Definition, examples, and more

Definition

The percentage of users who begin a free trial and subsequently convert to a paid subscription. This is one of the most important metrics for subscription apps with trials, reflecting onboarding success, feature adoption, and value communication.

How to Calculate

Trial Conversion Rate = Paid Conversions from Trial / Total Trial Starts x 100. For example: 4,400 / 8,000 = 55%.

Example

A meditation app has 8,000 trial starts per month. 4,400 convert to paid (55% trial-to-paid). Users who meditate 5+ times during the trial convert at 78%; users with 0-1 sessions convert at 12%. The app launches a '5 sessions in 7 days' challenge, boosting overall conversion to 62%.

Why Trial conversion rate Matters

Trial conversion rate is the most important metric for trial-based subscription apps. A productivity app improved conversion from 42% to 55% by adding an onboarding email series and in-app feature discovery nudges during the trial. That 13-point improvement meant 1,040 additional subscribers per month — $125K in annual revenue from optimizing the trial experience.

Frequently Asked Questions

What is a good trial conversion rate?

40-65% is strong for card-on-file trials (where users enter payment upfront). 10-25% is typical for no-card trials. The benchmark depends heavily on your trial model and app category.

How do I improve trial conversion?

Drive engagement during the trial — it is the #1 predictor. Send onboarding messages guiding users to core features. Create milestones and challenges. Send a reminder 24-48 hours before expiration. Show what they will lose if they do not convert.

Should I require a credit card for the trial?

Card-required trials convert at 50-70% but have fewer trial starts. No-card trials start more users (3-5x) but convert at 10-25%. Math usually favors card-required. Test both for your app.
