Accounting Churn Rate (Monthly) Calculator FAQ
Answers to common questions about monthly customer churn, revenue churn, recurring revenue retention, inputs, and results.
Use these answers to understand what the monthly churn metrics measure, which revenue movements belong in each input, and how to interpret the results consistently over time.
General monthly churn questions
Basic definitions and uses of the calculator.
What does a monthly churn rate measure?
It measures customer or recurring revenue losses occurring during one month relative to the base at the start of that month.
Who can use this calculator?
It can be used by accounting firms, bookkeeping businesses, subscription companies, and other businesses with recurring customer revenue.
Is customer churn the same as revenue churn?
No. Customer churn counts customers lost, while revenue churn measures the recurring revenue lost from the opening base.
Why track churn every month?
Using a consistent monthly period makes it easier to compare retention and revenue movement over time.
Inputs and classifications
How to categorize customers and recurring revenue movements.
What belongs in starting customers?
Use the count of active paying customers on the first day of the month.
What belongs in churned MRR?
Include recurring revenue lost through cancellations and downgrades during the month.
What counts as expansion MRR?
Include upgrades, added services, or higher recurring fees from customers that were active at the start of the month.
Where should revenue from new customers go?
Enter it as new MRR. It is included in ending MRR but not in net revenue churn.
How should reactivated customers be treated?
Use a consistent reporting policy. Their treatment can affect whether revenue is classified as new, expansion, or retained revenue.
Calculation and interpretation
How the main metrics are derived and read.
What is gross revenue churn?
It is churned MRR divided by starting MRR, expressed as a percentage, before expansion revenue is offset.
What is net revenue churn?
It is churned MRR less expansion MRR, divided by starting MRR, expressed as a percentage.
What does a negative net revenue churn rate mean?
It means expansion revenue from the opening customer base was higher than the recurring revenue lost from that base.
How is ending MRR calculated?
Starting MRR minus churned MRR plus expansion MRR plus new MRR equals ending MRR.
What does net MRR change show?
It shows the difference between ending MRR and starting MRR after all included movements.
Accuracy and reporting
Factors that can affect comparability and reliability.
Can I use annual contract values in this calculator?
Convert them to comparable monthly recurring amounts before entering them.
Should one-time setup fees be included?
No. The calculator is designed for recurring monthly revenue, not one-time charges.
Are results suitable for financial statements?
The results are management estimates. Use accounting records and established reporting policies for formal financial reporting.
Why might churn differ from my billing system report?
Differences can arise from timing, cancellation cutoffs, revenue recognition methods, credits, pauses, or classification rules.
How do you calculate monthly customer churn?
Divide customers lost during the month by customers at the start of the month, then multiply by 100.
