Age 5Explain it to a 5-year-oldStart with a picture
Imagine using Expansion revenue to answer this question: measure added recurring revenue from existing customers? Enter Starting cohort revenue, Ending cohort revenue, Churn and contraction; the calculator shows Expansion revenue. Try changing one number and watch what happens to Expansion revenue. The answer tells you Expansion revenue.
Age 15Explain it to a 15-year-oldConnect it to the formula
Expansion includes upgrades, add-ons and cross-sells from the starting cohort. Separate it from revenue contributed by newly acquired customers. The rule is Expansion revenue = ending existing-customer revenue − starting revenue + churn + contraction. Its input values are Starting cohort revenue, Ending cohort revenue, Churn and contraction, and the main result is Expansion revenue. Try changing one number and watch what happens to Expansion revenue.
CollegeExplain it at college levelState the model precisely
This tool models one operating decision from explicitly supplied company assumptions. The implemented relation is Expansion revenue = ending existing-customer revenue − starting revenue + churn + contraction, evaluated from Starting cohort revenue, Ending cohort revenue, Churn and contraction to produce Expansion revenue. Expansion includes upgrades, add-ons and cross-sells from the starting cohort. Separate it from revenue contributed by newly acquired customers. The model omits unentered taxes, cash timing, legal constraints and market uncertainty. Compare the output with company records and a downside scenario before committing resources.
The decision this tool supports
Measure added recurring revenue from existing customers.
Why the business model works
Expansion includes upgrades, add-ons and cross-sells from the starting cohort. Separate it from revenue contributed by newly acquired customers.
Inputs and operating assumptions
This model uses Starting cohort revenue (at least 0), Ending cohort revenue (at least 0), Churn and contraction (at least 0). Keep currencies, accounting treatment and time periods consistent with one another.
The formula
Expansion revenue = ending existing-customer revenue − starting revenue + churn + contraction
What the calculator produces
The primary output is Expansion revenue. Change one assumption at a time so the comparison remains explainable.
Before using the result in a decision
This compact model cannot capture every tax, accounting, legal, market or operational condition. Compare the output with current company records, cash timing and the downside scenario before committing resources.
