What to enter
| Input | Meaning and units |
|---|---|
| MRR for included accounts (currency/month) | Enter mrr for included accounts in currency/month. Use the measurement basis described below. |
| Included active accounts (accounts) | Enter a whole count in accounts; keep the reporting population consistent. |
Understanding your result
ARPA helps compare account economics across segments; inspect distributions because a few large accounts can dominate the mean.
Common mistakes
- Do not divide by seats while labeling the answer per account.
- Do not combine ARR with monthly account-revenue expectations without normalizing.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
Choose a consistent measurement basis
Keep the revenue base and account population aligned at a stated snapshot or averaging window. Explicitly include or exclude free accounts in both interpretation and comparisons.
A second independently worked case
Ten included accounts with zero MRR give ARPA zero. Inputs: MRR for included accounts: 0 currency/month; Included active accounts: 10 accounts. Results: Average recurring revenue per account: 0 currency/account/month.
Precision and output units
Displayed results: Average recurring revenue per account in currency/account/month, rounded to 2 decimal places. Display rounding does not establish the precision of the original measurements or estimates.

Common uses
- How much monthly recurring revenue did each active account represent on average
- Compare ARPA across scenarios under matching definitions.
How it works
Divide MRR by the active account count used to produce that MRR. Each account is one billing or customer entity under the chosen convention; seats and human users are different units.
Worked example
12,000 monthly recurring revenue ÷ 200 accounts = 60 per account per month. Enter mrr for included accounts 12000 currency/month, included active accounts 200 accounts. The independently worked result is average recurring revenue per account 60 currency/account/month. Compare this example with your reporting definitions before substituting your own figures.
FAQ
How is ARPA different from ARPU?
ARPA uses customer or billing accounts; ARPU uses users under the stated user definition. One account can contain several seats or users, so the denominators may differ considerably.
Does ARPA describe a typical customer?
Not necessarily. It is a mean. A small number of high-revenue accounts can raise the average, so inspect segments, distributions and concentration as well.
