What is Average Revenue Per User (ARPU)?

Average Revenue Per User (ARPU) is your total revenue divided by your number of users, usually measured per month or per year. If you earn $50,000 a month from 1,000 customers, your ARPU is $50. It tells you, on average, how much each user is worth in revenue.

ARPU is a quick way to gauge how well you're monetizing your audience. Rising ARPU means you're extracting more value per customer; falling ARPU can signal discounting, a shift to cheaper plans, or lots of low-value sign-ups.

How to use ARPU

Compare ARPU across customer segments to see where your real value lies. Often a small group of high-ARPU customers drives most of the revenue, which can reshape who you target and how you price.

• ARPU = total revenue ÷ number of active users in the period.
• Segment ARPU by plan or customer type to find your most valuable users.
• Raising ARPU through upsells is often cheaper than acquiring new customers.

Why ARPU matters for validation

ARPU connects directly to whether your unit economics work. A higher ARPU gives you more room to spend on acquiring customers and still profit. If your realistic ARPU is low, you'll need either very cheap acquisition or huge volume to build a real business — an important constraint to understand before you commit to an idea.
