How it works
Calculate account averages
ARPA equals MRR divided by paying accounts; annualized ARPA multiplies that monthly value by twelve.
Add context
Free-account share and net expansion show why an average can change even when customer count is stable.
Frequently asked questions
What is the ARPA formula?
Monthly ARPA equals ending monthly recurring revenue divided by active paying customer accounts in the same period.
Is ARPA the same as ARPU?
Not always. ARPA uses customer accounts; ARPU uses individual users. For a team SaaS product, one paying company may contain many users.
Should one-time fees be included?
No. Keep implementation fees and other non-recurring revenue outside MRR unless your accounting definition deliberately includes a normalized recurring component.
Can ARPA prove pricing quality?
No. It is an average. Review distribution by plan, segment and cohort alongside retention and margin.
