ARPU and ARPA Calculation: A Crucial Metric for Financial Health

In the highly competitive SaaS landscape, startups must focus on rapid growth and profitability. ARPU and ARPA are essential metrics for measuring customer value, optimizing pricing strategies, and making data-driven decisions. By mastering these metrics, startups can accelerate growth, secure funding, and achieve product-market fit.

Understanding ARPU and ARPA: Key metrics for SaaS success

‍

While often confused, ARPU and ARPA are distinct terms with specific calculations and implications for KPI fluctuation.

‍

What is ARPU ?

ARPU stands for "average revenue per user," representing the average revenue generated per user (not customer) over a given period. It’s a critical metric for growth across any service offering, and various commercial and pricing strategies, including upsell and cross-sell, can optimize this ratio.

‍

What is ARPA ?

ARPA (average revenue per account) measures the revenue per account over a period of time, focusing on subscription revenue from clients. Unlike ARPU, which applies to all users of a SaaS, ARPA provides insights into revenue split by client accounts, as a single client company may include multiple users.

‍

How to calculate ARPU and ARPA

Consider a company with the following subscribers and subscriptions:

• 10 clients opted for the premium annual subscription at €3,600 for 100 users each;
• 3 clients subscribed to the premium monthly package at €400 for also 100 users each;
• 20 small business clients, with a single user, picked the monthly "essential" service package at €8 per month.

To calculate ARPU or ARPA, we must first determine the period's MRR (Monthly Recurring Revenue). In our example, the total MRR amounts to:

(10 × (€3,600/12)) + (3 × €400) + (20 × €8) = €3,000 + €1,200 + €160 = €4,360.

Here are the ARPA and ARPU formulas:

ARPU = Total Revenue / Total Number of Users

In this example, ARPU (Average Revenue Per User) is : €4,360 / (10 × 100 + 3 × 100 + 20) = €3.30.‍

ARPA = Total Revenue / Total Number of Accounts

ARPA (Average Revenue Per Account): €4,360 / (10 + 3 + 20) = €132.12

‍

Factors influencing ARPU and ARPA

The example shows how client type and product offerings affect ARPA and ARPU. Different client segments, like small businesses or freelancers, typically subscribe to cheaper plans with fewer users, whereas bigger companies choose more comprehensive, higher-end services with more users. This highlights the importance of segmenting ARPU and ARPA by client or product type.

Pro tip : To gain deeper insights into customer behavior and revenue trends, consider cohort analysis. By tracking ARPU and ARPA for specific customer groups based on acquisition date, feature adoption, or other relevant criteria, you can identify high-value segments and optimize your strategies accordingly.

The strategic role of ARPA and ARPU in a SaaS business

‍

These metrics are vital for improving a recurring revenue company’s performance, offering various applications.

‍

An indicator of your ability to sell at various prices

In the previous example, the SaaS offering includes both a basic service level and a premium level, as well as pricing tiers according to the number of users. Segmenting ARPA and ARPU by customer type gives you more detailed and interesting data to track over time. These indicators inform you about your ability to sell more expensive or more comprehensive subscriptions.

Whether you're moving customers up to a higher tier (upselling) or enhancing subscriptions with additional services (cross-selling), you're increasing MRR. Analyzing the evolution of ARPA helps measure the effectiveness of your sales and marketing strategy and assess your pricing position.

‍

ARPU and churn rate

As a reminder, churn rate measures attrition, that is, the loss of customers over a period, either by number (churn rate) or by MRR amount (revenue churn). Segmenting customers increases relevance for tracking both ARPU and churn.

A high churn rate for a high ARPU has detrimental consequences for ARR growth. Monitoring these two indicators simultaneously helps to determine the actions needed to retain strategic subscribers.

‍‍

ARPA and ARPU’s impact on company CLV

LTV (lifetime value) represents the revenue a customer is expected to generate over the whole duration of their relationship with a company. The higher the ARPU and ARPA, the greater the LTV, especially if the churn rate remains below the company's defined SaaS metrics.

‍

Strategies for Increasing ARPU and ARPA

‍

A deep understanding of your customer base is essential to maximize ARPU and ARPA.

‍

Customer segmentation and analysis

Segment your customer base to identify high-value groups based on demographics, usage patterns, and revenue potential. Analyze these segments to uncover opportunities for tailored pricing and product offerings.

‍

Optimize pricing strategy

Experiment with different pricing models, such as tiered pricing, value-based pricing, or freemium models. Continuously monitor pricing effectiveness and adjust strategies as needed.

‍

Enhance customer retention

Invest in customer success and support to build strong relationships and reduce churn. Implement loyalty programs and referral incentives to encourage customer retention and expansion.

‍

Drive Upselling and Cross-Selling

Identify opportunities to offer additional products or services to existing customers. Personalize recommendations based on customer behavior and preferences.

By effectively leveraging ARPU and ARPA, SaaS startups can gain a competitive edge, optimize their business model, and achieve long-term success. Monitoring and analyzing these metrics will provide valuable insights to inform strategic decision-making and drive growth. Tools like Fincome can streamline this process by automating KPI calculations and providing valuable insights.
