Average revenue per account is the mean recurring revenue a single customer account produces in a period.
ARPA = recurring revenue for the period ÷ active accounts in that period
MetricHQ defines it the same way: the mean revenue generated from each customer account over a specific period, calculated monthly or annually.
Pick one period and hold it. Monthly ARPA and annual ARPA differ by a factor of twelve, and a chart that switches between them mid-series is worse than no chart.
The formula runs one way
A common phrasing gets this backwards: "the metric calculated by multiplying active customer accounts by average revenue per account."
That product is total recurring revenue, not ARPA. ARPA is the division that produces the average in the first place:
accounts x ARPA = total recurring revenue
total recurring revenue ÷ accounts = ARPA
If a source hands you the multiplication as the definition of ARPA, it has described the identity in reverse.
ARPA versus ARPU
Both average revenue. They divide by different things.
| Divides by | Answers | |
|---|---|---|
| ARPA | Active accounts, meaning companies | What is a customer worth |
| ARPU | Active users, meaning individual seats | What is a seat worth |
In consumer products the two collapse into one number, because an account is a person. In B2B they separate hard. A 400-seat enterprise account and a single-seat account are one account each to ARPA, and 401 users to ARPU.
Use ARPA for segmentation, pricing, and unit economics. Use ARPU when seat-level pricing or per-seat expansion is the thing you are steering.
What goes in the numerator
Recurring revenue only. The same exclusions that apply to ARR apply here: no one-time setup fees, no professional services, no usage overage above the committed floor.
Free accounts, trials, and $0 plans stay out of the denominator. Leaving them in is the fastest way to report a falling ARPA during a successful free-tier launch.
A worked example
A business closes the month with $840,000 of monthly recurring revenue across 1,200 paying accounts, plus 3,000 accounts on a free tier.
ARPA = $840,000 ÷ 1,200 = $700 per month, or $8,400 annualized
Counting the free accounts would give $840,000 ÷ 4,200 = $200, which describes nothing. It is not the price, not the average customer, and not a number any decision should rest on.
Now split the same book by segment:
| Segment | Accounts | MRR | ARPA |
|---|---|---|---|
| Enterprise | 60 | $420,000 | $7,000 |
| Mid-market | 240 | $288,000 | $1,200 |
| Self-serve | 900 | $132,000 | $147 |
| Blended | 1,200 | $840,000 | $700 |
No customer pays $700. The blended figure sits between three real populations and matches none of them. It will also move when the mix moves, with no price or packaging change at all: win 100 more self-serve accounts and blended ARPA falls, even though nothing got worse.
Definition pitfalls
- Inverting the formula, as above.
- Counting free, trial, and $0 accounts in the denominator.
- Including services and one-time fees in the numerator.
- Mixing monthly and annual bases in one trend.
- Reading a blended number across segments that behave differently.
- Calling a mix-driven move a pricing result. Always decompose ARPA change into
price, packaging, and mix before attributing it.
Questions people actually ask
Taken from the queries this page earns.
How do you calculate ARPA? Recurring revenue for a period divided by the active paying accounts in that period.
What is ARPA in business? The average recurring revenue per customer account. In finance it is read as a unit-economics input; in sales it is read as the value of a typical won account.
ARPA or ARPU? ARPA for B2B, where an account holds many users. ARPU where the account and the user are the same thing, or where you price per seat.
Is a rising ARPA good? Only after decomposition. Rising because you moved upmarket is a strategy working. Rising because self-serve churned out is a problem wearing a good number.
Where ARPA fits
ARPA is an input to customer lifetime value and to payback period, and sits in the Measurement pillar of the Tenbound Pipeline Architecture Standard.
Read it beside net dollar retention. ARPA says what an account is worth today. Retention says whether that worth is compounding or leaking.
