What to do with this result
Replace the constant rates with observed cohort curves before budgeting; aggregate averages can hide poor recent cohorts.

Calculation method
Month t contribution = starting customers × (1 − churn)^t × ARPU × (1 + expansion)^t × gross margin; subtract initial acquisition cost.
Assumptions and limitations
- Example inputs are editable scenarios, not Aryo results or independently verified industry benchmarks.
- Use one matched customer cohort and consistent periods. Recurring revenue, bookings and cash are different measures.
- First month has the full starting cohort. Churn and expansion are applied between months; no new customers join this cohort.
