Average Revenue Per Account Calculator

About this calculator

Average Revenue Per Account (ARPA) — also called ARPU when measured per user — is a core SaaS and subscription-business metric found by dividing total revenue over a period by the number of active accounts. It condenses a company's entire customer base into a single figure showing how much revenue, on average, each customer generates.

This calculator computes ARPA from total revenue and account count. It's tracked by SaaS finance teams, revenue operations analysts, and startup founders as a key input for forecasting revenue growth, benchmarking pricing tiers against competitors, and — combined with customer acquisition cost (CAC) — judging whether a business is acquiring customers at a sustainable ratio of spend to revenue.
