Trial-to-paid Conversion Calculator

Compute trial-to-paid conversion rate and estimate required conversions to hit a target.

Trial-to-paid measures the % of trial users who become paying customers within a defined window.

Track by cohort and channel to understand lead quality and where onboarding or pricing friction is blocking conversion.

Example

Using the default inputs, the result is:
9%
Trials started
2,000
Trials converted to paid
180
Target trial-to-paid (optional)
12%

How to calculate

  1. Enter trials started for the cohort/window.
  2. Enter trials that converted to paid within the window.
  3. Optionally enter a target trial-to-paid rate to compute required paid conversions.

Formula

Trial-to-paid = paid conversions / trials started
  • Uses a single conversion window; use cohorts for long sales cycles.
  • Trials and paid conversions reflect the same cohort definition.

FAQ

What window should I use (7/14/30 days)-
Use a window that matches your typical conversion lag. If sales-assisted conversions take longer, track them separately or extend the window so you don't undercount conversions.
Should I include free users in trials-
Only if the definition is consistent. Many teams separate free-to-paid and trial-to-paid because the activation and conversion behavior differs.

Common mistakes

  • Using a window that's too short (under-counts conversions for long sales cycles).
  • Mixing self-serve and sales-assisted trials (different funnels).
  • Changing trial definitions and comparing rates as if equal.

Quick checks

  • Keep time units consistent (monthly vs annual) across inputs and outputs.
  • Segment by cohort/channel/plan before trusting a blended average.
