Description

Subtract excluded from positive started for eligible and divide paid by eligible.

Marketing rates compare a counted outcome with a declared cohort or exposure base. Reentries, exclusions, and distinct funnel stages can change the denominator substantially.

Subtract excluded from positive started for eligible and divide paid by eligible.

When to use this tool

Use Subscription Trial Paid Transition Share when you need a transparent cohort or exposure ratio.

Limitations and assumptions

  • This measures the supplied cohort and exclusions; timing, attribution, and reasons for conversion are not analyzed.
  • Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
  • Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.

Alternative or Complementary methods

Reconcile event definitions, attribution windows, and deduplication against the source analytics before comparing rates.
