Definition

Trial-to-paid conversion rate measures what % of trial users become paying customers within a defined window. It's a bridge metric between activation and revenue.

Formula

Trial-to-paid = paid conversions / trials started

Choose a conversion window

  • Self-serve trials: 7-30 days is common (depends on product complexity).
  • Sales-assisted conversions: track separately; windows are often longer.
  • Use cohorts so you don't undercount late conversions.

How to improve trial-to-paid

  • Improve activation and time-to-value (trial users must see value quickly).
  • Clarify pricing and packaging (reduce confusion and surprise).
  • Add conversion nudges: in-product prompts, lifecycle emails, sales follow-up for high intent.

Trial-to-paid QA checklist

  • Use a fixed conversion window aligned to your sales cycle.
  • Exclude free-to-paid migrations from legacy plans unless defined as trials.
  • Track trial extensions separately from standard trials.

Benchmarks and context

  • Self-serve products often convert faster; sales-assisted trials convert slower.
  • Short trials can raise conversion but hurt activation if time-to-value is long.
  • Compare by segment and acquisition channel to avoid blended averages.

Common mistakes

  • Mixing self-serve and sales-assisted trials (different funnels).
  • Using a too-short window for long-cycle conversions.
  • Optimizing conversion while harming retention (watch churn/GRR).
