Trial-to-Paid Conversion Rate
The percentage of free trial users who convert to a paid subscription. The most critical metric for product-led SaaS growth.
Formula
(Converted Trials / Total Trials) x 100
Why trial-to-paid conversion rate matters
Trial-to-paid conversion is the pivot point of your entire product-led growth funnel. Every dollar spent on acquisition is wasted if trial users do not convert. Even small improvements here compound dramatically - moving from 5% to 7% conversion is a 40% increase in revenue from the same traffic.
This metric reveals the effectiveness of your onboarding, time-to-value, and product-market fit. Low conversion often points to an activation problem rather than a traffic problem.

How to calculate trial-to-paid conversion rate
Divide the number of trial users who upgraded to paid by the total number of trial starts in the same cohort. Always measure by cohort (trial start date) rather than calendar period to avoid mixing different trial durations.

Trial-to-Paid Conversion Rate examples
An analytics platform offers a 14-day free trial. Of 1,000 monthly trial starts, 70 convert (7%). They discover users who create their first report within 3 days convert at 25%.
Benchmark: 3-8% for opt-in, 40-60% for opt-out trials
What is a good trial-to-paid conversion rate?
Opt-in free trials (no credit card required): 2-5% conversion is typical, 8-10% is excellent. Opt-out trials (credit card required): 40-60% is typical. Freemium models: 1-3% is standard.
How to Track in KISSmetrics
Track trial_started and trial_converted events in KISSmetrics. Build a Funnel Report showing the conversion path. Use the Cohort Report to see how conversion rates change over time and identify what trial start cohorts convert best.
Common Mistakes
- -Not segmenting by trial type (credit card vs no credit card)
- -Measuring conversion too early - some users need the full trial period to evaluate
- -Treating all trial users equally instead of focusing on activated users
- -Not tracking what actions correlate with conversion (activation events)
Pro Tips
- +Identify your "aha moment" - the specific action that correlates most strongly with conversion
- +Experiment with trial length: shorter trials create urgency, longer trials allow deeper evaluation
- +Send targeted emails based on trial behavior, not just time-based drip sequences
- +Track the conversion window - when in the trial do most conversions happen?

Activation Rate
Activation rate is the percentage of new users who complete a predefined set of key actions that indicate they have experienced the core value of a product, marking their transition from signup to engaged user.
Time to Value
Time to value (TTV) measures the elapsed time between a user's first interaction with a product - such as signing up or making a purchase - and the moment they experience the product's core value, directly impacting activation, retention, and satisfaction.
Free-to-Paid Conversion Rate
Free-to-paid conversion rate is the percentage of users on a free plan who upgrade to a paid subscription, calculated as upgraded users divided by the free user base at the start of the period, times 100. Typical freemium rates land between 2% and 5%. It is the core monetization metric for freemium products, and it behaves differently from trial-to-paid conversion because there is no expiry date forcing a decision.
Onboarding Completion Rate
The percentage of new users who complete all steps in your defined onboarding flow. A leading indicator of activation and long-term retention.
