ARPU

Also called: Average Revenue Per User, Average Revenue Per Account

TL;DR

Average Revenue Per User, total recurring revenue divided by active customer or user count, a measure of monetization depth.

ARPU divides recurring revenue by the count of paying customers. It's a per-customer monetization measure that helps spot whether top-line growth is coming from more customers or from customers paying more. Rising ARPU on a flat customer count means the company is moving upmarket; flat ARPU on rising customer count means the company is moving downmarket.

For multi-product or multi-tier businesses, ARPU is most useful when broken down by tier or segment. Aggregate ARPU on a complex pricing model often hides more than it reveals.

Formula

ARPU = Total Revenue in Period ÷ Number of Active Users in Period

Total Revenue , Total subscription revenue earned in the period
Active Users , Average number of paying users during the same period

Worked example

A consumer SaaS earns $1.2M in March from 24,000 paying users → ARPU $50/mo. A pricing test that lifts the median plan from $39 to $59 raises ARPU to $63 with a 12% drop in paid conversion, net positive.

Common pitfalls

•Computing ARPU on a base that includes free users.
•Reporting aggregate ARPU when the price tiers behave differently.
•Tracking ARPU instead of margin per user, high ARPU with poor margin is no win.

When this shows up in a pitch deck

ARPU appears on the Business Model or Unit Economics slide for SaaS companies and on the Engagement slide for consumer apps.
