What is ARPU (Average Revenue Per User)?

Why It Matters

ARPU is one half of the equation that determines whether a subscription business can profitably keep acquiring users, comparing it against customer acquisition cost is one of the fastest ways to see if the unit economics actually work at the current price point. When ARPU rises while the user base barely moves, that gap points specifically to pricing or plan mix changes rather than growth, letting a team separate two very different growth stories that a single revenue total would hide. Because it's scoped to individuals rather than accounts, it's also the natural fit for consumer and app businesses where a company account structure like ARPA doesn't apply. Tracking ARPU trends over time is what informs pricing strategy decisions like whether a higher-tier plan is actually working.

Example

A subscription app generates $80,000 in monthly recurring revenue from 4,000 active subscribers. ARPU is $80,000 divided by 4,000, which equals $20 per user per month. If the company introduces a higher-priced annual plan and average revenue climbs to $23 per user the following quarter while the subscriber count barely moves, that gap points to pricing or plan mix changes rather than growth in the user base. Comparing ARPU against customer acquisition cost is one of the fastest ways to see whether a subscription business can profitably keep acquiring new users at its current price point.

Frequently Asked Questions

• How is ARPU different from ARPA?

  ARPU measures revenue per individual user, common in consumer subscription and app businesses, while ARPA measures revenue per B2B account, which can include multiple seats or users under one paying account.

• Why does ARPU matter for evaluating acquisition spend?

  Comparing ARPU against customer acquisition cost is one of the fastest ways to see whether a business can profitably keep acquiring new users, since it shows how much revenue each new user is worth relative to what it cost to get them.

• What does rising ARPU with a flat user base indicate?

  It points to pricing or plan mix changes, like more users choosing a higher-priced plan, rather than growth in the user base itself, the same distinction seen when a higher-priced annual plan lifted ARPU from $20 to $23 without much subscriber growth.

• How often is ARPU tracked?

  Most consumer subscription businesses calculate it monthly alongside MRR and active user counts, watching the trend over several periods to catch pricing or plan-mix shifts.

• How do you increase ARPU?

  Introducing higher-priced tiers or annual plans, encouraging upgrades, and adjusting the overall plan mix toward higher-value options are the primary levers for raising ARPU without needing to grow the user base.
