Why it matters

Trial conversion is a direct signal of onboarding quality, product fit, and pricing friction in trial-led growth models.

When to use

  • Reviewing onboarding changes
  • Comparing trial cohorts
  • Estimating paid customer volume from top-of-funnel trials

Inputs & Outputs

Inputs

  • Trials started are the users or accounts that entered the trial in the cohort.
  • Paid conversions are the subset that became paying customers.

Outputs

  • Conversion rate shows the share of trials that became paid.
  • Non-converting trials show how many trial starts did not convert.

Trial conversion formula

Divide paid conversions by trial starts and convert the result into a percentage.

Trial-to-paid conversion = paid conversions / trials started

Worked example

1

Onboarding experiment review

A cohort included 4,200 trial starts and 378 paid conversions.

Inputs

  • Trials started: 4,200
  • Paid conversions: 378

Steps

  • Conversion = 378 / 4,200 = 9%

Result

  • Trial-to-paid conversion is 9%.

Edge cases & caveats

  • Conversion timing windows can change the result materially.
  • Short trials and long enterprise evaluations should not be compared directly.

Frequently Asked Questions

Should I measure by user or account?

Use the unit that matches your buying motion. B2B SaaS often prefers accounts, while self-serve products may use users.

Why is cohort timing important?

Because some trials convert later than others, and an incomplete window can understate the true conversion rate.
