Why Measure Trial-to-Paid Conversion?
In Product-Led Growth (PLG) SaaS models, the free trial is your primary sales funnel. Optimizing your trial conversion rate unlocks compounding growth without increasing ad spend. Tracking this metric helps growth teams:
- Evaluate Onboarding Friction: Test whether requesting a credit card upfront improves net ARR.
- Forecast Recurring Revenue: Project new MRR based on upcoming user signup cohorts.
- Optimize Customer Acquisition Costs (CAC): Ensure trial user acquisition spend is recouped quickly.
Mathematical Formulas
1. Trial to Paid Conversion Rate
\[\text{Conversion Rate \%} = \left( \frac{\text{New Paying Subscribers}}{\text{Total Free Trial Signups}} \right) \times 100\%\]2. Revenue Impact Metrics
\[\text{New MRR Generated} = \text{New Paying Subscribers} \times \text{ARPU}\] \[\text{New ARR Generated} = \text{New MRR Generated} \times 12\] \[\text{Revenue Per Trial Signup} = \frac{\text{New MRR Generated}}{\text{Total Free Trial Signups}}\]Industry Benchmarks Matrix
