What is ARPPU (Average Revenue per Paying User)?
ARPPU is the average revenue generated by customers who paid during a specific period (month, quarter, year).
It focuses on monetization quality among payers—useful when most users don’t pay and blended averages hide real pricing and conversion dynamics.
In corporate finance terms, ARPPU helps connect pricing and revenue quality to unit economics (LTV, CAC, payback), operating leverage, and ultimately value creation.
Formula
Example
A SaaS has monthly revenue from paying users of $120,000 and 2,500 paying users.
So ARPPU is $48 per paying user per month.
Annualized per paying user:
That’s $576 per paying user per year, which can be used alongside churn and gross margin to pressure-test LTV and CAC payback assumptions.
