Growth Accounting

Breaking down user growth into its components. Reveals whether growth is healthy or hollow.

End MAU = Start MAU + New + Resurrected − Churned

What it measures

A framework that decomposes user growth into New (first-time users), Retained (continued from last period), Resurrected (returned after absence), and Churned (stopped using).

Calculation Variants

User Quick Ratio
(New + Resurrected) / Churned. Measures growth efficiency. A ratio of 2.0 means you gain 2 users for every 1 you lose.
Gross Retention
Retained / Start MAU. Shows the floor of your user base stability.

What to watch

  • High resurrection, high churn: Users cycle in and out. You're not building a stable base. Investigate why users leave and what brings them back.
  • Low resurrection, low churn: Stable but may lack growth. Your existing users stay, but you're not winning back lapsed users.
  • User Quick Ratio above 4: Excellent for SaaS. Above 1.5 is very good for consumer apps. Below 1 means you're shrinking.

In practice

A mobile game showed 15% MAU growth, but growth accounting revealed 60% of "active" users each month were resurrected players who churned again within weeks. True retained users were declining. They shifted focus from re-engagement campaigns to fixing the core gameplay loop that caused churn in the first place.

Illustrative scenario — a representative composite, not a specific company.

Vanity Risk

Top-line MAU growth is vanity when it masks a leaky bucket. If 60% of your "active" users each month are resurrected churners, you have a revolving door, not real growth.
