Average Revenue Per User (ARPU)
The mean revenue generated per active user or account over a given period, calculated by dividing total revenue by the number of users, used to track monetization efficiency.
ARPU measures how effectively you monetize your user base. It is calculated as total revenue divided by total users for a given period (monthly or annually). For a freemium product with 10,000 users generating $50,000 monthly revenue, ARPU is $5/month. For paying customers only, ARPPU (Average Revenue Per Paying User) is often more actionable.
ARPU trends reveal monetization health independent of user growth. Rising ARPU indicates successful upselling, price increases, or better-monetizing user segments. Falling ARPU might indicate a shift toward lower-value customers, pricing pressure, or plan downgrades. Decomposing ARPU by segment (plan tier, company size, acquisition channel) reveals which customers generate the most value.
Growth teams improve ARPU through pricing optimization (finding the price that maximizes revenue, not just conversions), feature packaging (bundling features into tiers that encourage upgrades), usage-based pricing (aligning price with value received), and personalized upsell campaigns targeting customers whose usage patterns suggest they would benefit from higher tiers. AI-powered pricing experiments and propensity-to-upgrade models can lift ARPU by 10-25% without increasing acquisition costs.

Growth Loop
A self-reinforcing cycle where each cohort of users generates inputs (data, content, referrals) that attract the next cohort, creating compounding growth.
Churn
The rate at which customers stop using or paying for a product over a given period, typically measured as monthly or annual churn percentage.
Activation Rate
The percentage of new signups who complete a key action (the 'aha moment') that correlates with long-term retention and product value realization.
