How to use this calculator

This calculator models the relationship between account health scores and expansion revenue. Expansion ARR in B2B service companies is not driven by sales calls to existing clients — it is driven by the account being in healthy enough standing that the client wants more. The “10% uplift” result shows the incremental expansion ARR if you improve the proportion of healthy accounts by 10 percentage points. Use this figure alongside the churn cost calculator to build the full business case for structured account management.
