Different cadence
MRR watches what changed this month.
ARR scales that story to yearly language investors already expect.
Annual prepay needs care
Cash upfront is not automatically “this month’s MRR” unless your rulebook says so.
Slice annual deals into twelve even pieces when you compare months.
Pair calculators cleanly
Use MRR and ARR calculators with one definition of paying customer count.
Bring churn calculators in when totals look too happy.
