Frequently Asked Questions
When does MRR x 12 equal ARR?
Only when you have no annual contracts, no seasonality, and stable MRR. In practice, this is rare. Always calculate ARR properly.
Should I include usage-based revenue in ARR?
Include only if usage is predictable and contracted. Variable usage is better tracked separately from committed ARR.
