ARPU

A metric measuring the average amount of revenue generated by an individual subscriber, user, or customer over a specific period.

Average Revenue Per User (ARPU) is a key operational metric used primarily by subscription-based, telecommunications, digital media, and software-as-a-service (SaaS) companies. It measures the average amount of revenue generated by an individual subscriber, user, or customer over a specific period, typically monthly or annually. This metric helps investors evaluate how effectively a company is monetizing its user base. To calculate ARPU, a company's total revenue over a specific timeframe is divided by the average number of active users during that same period. Investors track this metric closely because it reveals whether a business can grow its top-line revenue through deeper monetization of its existing customer base, rather than relying solely on expensive new customer acquisition campaigns. An increasing ARPU is generally a positive signal, indicating strong pricing power, successful upselling of premium tiers, or improved advertising monetization. Conversely, a declining ARPU can signal that a company is discounting its services to retain users, facing intense competition, or struggling to convert free users into paying customers. When analyzing ARPU, investors should compare it alongside user growth, as a rising ARPU caused by losing low-value customers might mask a shrinking overall business.

A streaming service generates $45,000,000 in subscription revenue during a quarter. At the start of the quarter, it has 1,900,000 active users, and at the end, it has 2,100,000 active users. The average number of users is (1,900,000 + 2,100,000) / 2 = 2,000,000. The quarterly ARPU is $45,000,000 / 2,000,000 = $22.50.
