What is average revenue per user (ARPU)?
ARPU is a company's revenue from its users, divided by how many users it had on average.[S2] Each company chooses which revenue, which users and which period to count.[S1]
The name varies too: per user, per person, per account or per subscriber.
How is ARPU worked out?
The basic formula is revenue in a period ÷ average number of users in that period.
Three companies on Cityfort use three methods:
- Meta divides a quarter's Family of Apps revenue by its average daily active people. It calls this ARPP.[S4] Its yearly ARPP was 57 US$ per person (FY2025).
- Reddit divides a quarter's revenue in a region by its average daily users there.[S2]
- Verizon divides postpaid wireless service revenue by its average postpaid accounts. It calls this ARPA.[S3]
Where do you find ARPU in a 10-K or 10-Q?
It is not in the financial statements. Look in Management's Discussion and Analysis (MD&A): Item 7 of a 10-K, or Part I, Item 2 of a 10-Q.[S5][S6] Meta's sits under "Trends in Our Family Metrics."[S4]
SEC guidance expects a clear definition and how it is calculated.[S1]
What does ARPU leave out?
- Costs. It counts revenue only, not the cost of serving each user.[S4]
- Some revenue. Verizon's ARPA leaves out device payment plan billings, insurance premiums and regulatory fees.[S3]
- The notes' regional split. Reddit places ad revenue where ads were shown, not by billing address.[S2]
- A fixed method. Meta updated its ARPP definition in the first quarter of 2024 and recast earlier figures.[S4]
