Step-by-step calculation:

Frequently Asked Questions

Why is ARPA important?

ARPA is fundamental for understanding unit economics. It helps businesses evaluate the quality of their revenue streams and determines if their customer acquisition costs (CAC) are sustainable relative to the value each account brings.

What is a good ARPA?

There is no single "good" number; it depends on your market segment. Enterprise-grade solutions often have high ARPA due to high touch requirements, while SMB-focused tools rely on lower ARPA but higher customer volume.

How to increase ARPA?

Companies typically increase ARPA by focusing on upselling existing customers to higher-value tiers, cross-selling complementary products or features, and adjusting pricing structures to reflect added value.
