Churn vs Revenue Churn Calculator
Retention quality signal.
Compare customer churn against revenue churn to reveal customer-mix quality and the retention curve hidden inside the headline number.
What this tool does
This tool compares customer churn against revenue churn to reveal which type of customer is leaving your business. By examining the gap between these two metrics, it illustrates whether departing customers represent a disproportionate share of your revenue. A positive gap suggests you're losing higher-value accounts, while a negative gap indicates lower-value customers are churning. The calculator uses your customer churn rate, revenue churn rate, and average monthly recurring revenue figures to model this relationship. The result shows the magnitude of the gap and what it signals about your customer base composition. This is useful for understanding retention patterns and identifying whether churn affects your business uniformly or concentrates among specific customer segments. The output is for illustrative purposes and assumes your input figures accurately reflect the measured periods.

Customer churn counts how many customers leave; revenue churn measures the value of what leaves. The gap reveals customer mix. If revenue churn exceeds customer churn, high-value customers are disproportionately leaving - a serious warning. If customer churn exceeds revenue churn, low-value customers are filtering out while high-value ones stay - usually a healthy sign.
5% customer churn, 7% revenue churn = +2 point gap. Revenue churn higher means average leaving customer is higher-value than average remaining. This signals either upmarket customers disengaging (product-market fit issue with premium segment) or pricing changes driving away highest-paying customers.
top-tier SaaS operates with revenue churn below customer churn because high-value customers have more at stake (deeper integration, more seats, higher workflow dependence). A business where 2k/month customers leave at same rate as 200/month customers has serious product issues at the top end.
Run it with sensible defaults
Using customer churn of 5%, revenue churn of 7%, avg mrr lost per churn of 0, avg mrr retained of 0, the calculation works out to 2.00 pts. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Customer Churn %, Revenue Churn %, Avg MRR Lost per Churn, and Avg MRR Retained — do not pull with equal force. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the option with the lower calculated total changes.
How the math works
Gap = revenue churn % - customer churn %. Positive gap (revenue > customer): losing high-value customers. Negative: filtering out low-value.
Using this as a check-in
Re-run this every three months. A single reading tells you where you stand; four readings tell you whether things are improving. The trend matters more than any individual snapshot.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
5% customer churn vs 7% revenue churn = 2.00 pts.

Sources & Methodology
Methodology
This calculator computes the churn gap by subtracting customer churn percentage from revenue churn percentage. The result reveals whether lost customers represent disproportionately high or low revenue value relative to the overall customer base. A positive gap indicates that departing customers generated above-average revenue per account, suggesting the business is losing higher-value relationships. A negative gap suggests lost customers were below-average revenue contributors, indicating natural attrition of lower-value accounts. The calculation applies the two churn rates directly without adjustment for timing, seasonality, or cohort effects. It models churn as occurring uniformly and does not account for acquisition costs, lifetime value recovery potential, or the composition of remaining customers. The metric serves as a diagnostic signal only and should be interpreted alongside absolute churn rates and business context.
