FAQ

Frequently asked questions

How the calculation works and where its limits are.

What is ARPA (Average Revenue Per Account) and how is it used?

ARPA (or ARPU - Average Revenue Per User) measures the average amount of monthly or annual recurring revenue generated per active customer account (Total MRR / Total Paying Customers). It serves as a baseline for pricing tier adjustments, expansion tracking, and customer acquisition payback models.

What is the difference between ARPA and ACV (Annual Contract Value)?

ARPA is typically evaluated monthly (or annualized) across all active customer segments, including self-serve SMB and enterprise accounts. ACV represents the average annualized revenue contract signed by sales-led enterprise customers.

How does increasing ARPA improve SaaS valuation and unit economics?

Higher ARPA allows companies to spend more on Customer Acquisition Cost (CAC) while maintaining rapid payback periods (<12 months), creating a stronger moat and accelerating compound ARR growth.

Is this ARPA calculation financial or accounting advice?

No. All metrics are deterministic unit economic formulas based on entered revenue and account figures. Consult your finance team for official board reporting.

What should I do after calculating my average revenue per account?

Multiply ARPA by your average customer lifetime (from our Subscription Churn Calculator) to calculate Customer Lifetime Value (LTV) and evaluate your LTV:CAC ratio.
