How this calculation works

The reciprocal of monthly churn estimates lifespan. Monthly ARPA multiplied by gross margin and lifespan estimates gross-profit CLV.

Before you start

What you need

Monthly ARPA, gross margin, monthly churn, and currency.

Useful output

What you receive

Estimated CLV, implied lifespan, monthly gross profit, assumptions, and CSV.

Decision guardrail

What this does not decide

This shortcut can overstate value when churn changes over time and excludes discounting, expansion, acquisition cost, and cohort effects.

Practical uses

Where this tool helps

Set a rough acquisition-spend ceiling.
Compare customer segments consistently.
Check CLV sensitivity to churn.

Data boundary

Financial inputs remain local
