ARPU & ARPA Calculator
Average revenue per user, per paying user (ARPPU) and per account (ARPA) for a month, quarter or year, with the average user base, annualised figures, change.
ARPU, ARPPU and ARPA for the period, the paying share, annualised and monthly ARPU, revenue per user per day and the change against a previous period’s ARPU.
Example: 120 000 in a month over 9 000 → 11 000 users (average 10 000): ARPU 12, ARPPU 150 for 800 paying users (8 %), ARPA 300 for 400 accounts, +9.1 % on last month’s 11.
Revenue over a base,
with the base defined.
How the three averages differ, why the user base is averaged, and what the annualised figure means.
Three denominators
ARPU divides the period's revenue by the users in it, ARPPU by the paying users only, ARPA by accounts (a company with twenty seats is one account). The same revenue gives three very different numbers; a low paying share makes ARPU and ARPPU diverge, and the page says so when under 5 % pay.
The base and the period
A base that grows during the period overstates or understates the average; with start and end counts the page uses their mean, with one count it uses that and notes it. Monthly, quarterly and yearly figures are annualised by × 12, × 4 and × 1, and revenue per user per day divides by the days in the period (30 / 91 / 365 unless you enter the exact count). The change against a previous ARPU is a plain percentage.
Definitions are yours
Whether "users" means active, registered or billable, whether revenue is recognised or billed, and how trials count, are your conventions — the metric only means something when they stay the same from period to period. No benchmarks are embedded. Nothing leaves the browser; the same four anonymous usage counts as the rest of the site apply.

- ARPU = revenue ÷ average users ((start + end)/2); ARPPU = revenue ÷ paying users; ARPA = revenue ÷ accounts; annualised × 12 / 4 / 1; per day ÷ days in the period
