ARR Calculator FAQ
Is ARR the same as yearly revenue?
No. ARR is the yearly run rate of recurring revenue at a point in time; actual revenue over a year differs as customers join and leave.
Should services be included?
No – only recurring subscription revenue.
What growth rate is realistic?
Early SaaS companies may grow 5–15% a month; growth usually slows as revenue rises.
Why months to target?
It turns a revenue goal into a timeline.
ARR as a run rate
ARR is a snapshot: it says what recurring revenue would be over a year if nothing changed. It is the standard size measure for subscription businesses because it ignores one-off income.
Projections at constant growth are optimistic over long periods; treat them as scenarios.
Use consistent definitions over time: count customers and revenue the same way every month, separate one-off fees from recurring revenue, and compare cohorts rather than mixing old and new customers.
Benchmarks from other companies are only a rough guide, because business models, prices and customer types differ. Your own trend from month to month is usually more informative than a comparison with an industry average.
