What is ARPA (Average Revenue Per Account)?

ARPA or Average Revenue Per Account is a metric used most often by subscription and SaaS based companies that represents the average revenue generated per customer account per year or month. Typically in the SaaS / Subscription world it’s referring to the average monthly recurring revenue (MRR) per account. It’s a powerful metric because it can be used by businesses to get a clear understanding of profitability on a granular level.

ARPA vs ARPU - What is the difference?

The key difference between ARPA and ARPU is in the level of granularity each metric reprepresents. It’s common in the B2B world that some of your customers may have multiple uers in their organization. Measuring both ARPA and ARPU becomes especially useful to companies that have subscripion pricing based on usage or per seat.

For example, Slack, the popular meeting space software charges per user for use of the platform. A team of Slack users within a company may have a low monthly subscription cost given the discounts for the overall acount, but Slack can sill measure both the revenue derived from the total account with ARPA and at the individaul user level with ARPU. Measuring both of these metrics gives Slack more granular insights into revenue, especially when comparing one customer organization to another.

How to calculate ARPA and ARPU

The calculation for both ARPA and ARPU are esentially the same.

*ARPA* is calculated by dividing total revenues over a period of time by the total number of customer accounts during that same period of time.

For example, consider company A has 1,000 customer accounts and is generating $100,000 in total revenue per month. Average Revenue per Account (ARPA) would be = $100,000 / 1,000 = $100 per account per month.

*ARPU* is calculated in a similar way, subsituting the accounts variable for users.

For example, consider company B has 1,000 indivdual users and is generating $200,000 in revenue per month. Average Revenue per User (ARPU) would be = $200,000 / 1,000 = $200 per user monthly.

Why are ARPA and ARPU important?

First and foremost they can be a key indicator of profitability and growth. Second, they can allow you to drill down and understand each of your customers on a more granular financial level. If your ARPA increases over time it may be an indicator that your sales and marketing efforts are having a positive effect.
