Definition
Average Revenue Per User (ARPU) calculates the mean revenue each active user generates over a specific period (usually monthly). It is a foundational unit economics metric that directly impacts LTV calculations, pricing strategy decisions, and growth investment thresholds. ARPU trending upward indicates successful upselling, price optimization, or higher-value user acquisition. ARPU trending downward may signal plan downgrades, discounting erosion, or shifting user mix.
Formula
How to measure
Divide total revenue in the period by the number of active users (or paying users — specify which). Report both ARPU (all users, including free) and ARPPU (paying users only) for a complete picture. Segment by plan tier, geography, and user tenure.
Industry benchmarks
B2B SaaS: $50–500/month ARPU depending on market segment. Consumer subscriptions: $5–15/month. Fintech: varies widely ($1–50/month). The trend matters more than the absolute number — consistent ARPU growth signals pricing power.
