Average Revenue Per Unit (ARPU): Definition, Formula, and Use

November 1, 2023


In today’s data-driven business environment, understanding how much revenue a business generates from each customer or unit becomes paramount. One of the key metrics that provide insights into this aspect is Average Revenue Per Unit or ARPU. This metric is prevalent in various industries, including telecommunications, software-as-a-service (SaaS), and digital media, to name a few. Here, we delve deep into understanding ARPU, its significance, calculation, and its application in business contexts.


Average Revenue Per Unit (ARPU) is a measure used by companies to capture the average revenue generated per user or unit, over a specific period. In essence, it calculates how much each customer (or unit) contributes to the company’s revenues on average.


The ARPU is calculated using the following formula:

ARPU = Total Revenue during the period / Number of Units or Users during the same period


– Total Revenue refers to the total income a company generates (excluding any taxes or charges).
– Number of Units or Users denotes the average number of active customers or units for that period.

Importance of ARPU

Performance Tracking: ARPU helps businesses track their performance over time. If ARPU is increasing, it indicates that the company is successfully upselling or monetizing its user base more effectively. Conversely, a decreasing ARPU can signal challenges in the business model or market saturation.

Customer Value Insights: It gives an insight into the value of the customers. Higher ARPU indicates that customers are purchasing premium products or services or making frequent purchases.

Strategic Decision Making: Insights from ARPU can guide a company’s marketing, sales, and product strategies. For example, if ARPU is low, a business might invest in upselling or cross-selling initiatives.

Segmentation: ARPU can be used to segment the customer base. Different customer segments (e.g., premium vs. standard users) might have different ARPUs, which can be used for targeted marketing and product offerings.

Investor Relations: ARPU is a key metric that investors and analysts often look at when evaluating the health and growth potential of subscription-based businesses.

How ARPU is Used

Telecom operators often use ARPU to measure monthly revenues from each subscriber. It helps them understand subscriber behavior, evaluate pricing strategies, and assess promotional campaigns.

SaaS Businesses
For SaaS companies, ARPU provides insights into the average revenue generated from each customer, helping them tailor their service packages, pricing tiers, and customer acquisition strategies.

E-commerce platforms can use ARPU to evaluate the effectiveness of marketing campaigns, promotional offers, and loyalty programs.

Streaming Services
Platforms like Netflix or Spotify monitor ARPU to assess how much each subscriber is worth, guiding decisions on content acquisition, production, and licensing.

Game Developers
In the mobile gaming industry, ARPU helps developers understand in-app purchase behavior, the effectiveness of ads, and the value generated from different user segments.


While ARPU is a valuable metric, it has its limitations:

1. Doesn’t Account for Profit: ARPU only measures revenue and doesn’t consider the cost structure. Two companies might have the same ARPU, but different profit margins.

2. Over-generalization: ARPU provides an average figure, which can sometimes mask the nuances of different customer segments.

3. Fluctuations: External factors, like seasonal changes or one-off events, can cause short-term fluctuations in ARPU, which might not reflect the true long-term trend.


Average Revenue Per Unit (ARPU) is a versatile and valuable metric that allows businesses to gain a clearer understanding of their revenue generation capabilities at the granular level of individual users or units. By offering insights into customer value and revenue trends, ARPU serves as a compass for businesses to steer their strategies and initiatives for optimal growth and profitability.
