Growth Rate of Users
The period-over-period percentage change in total active users: the change in user count divided by the starting user count.

What it measures
The percentage change in total active users from one period to the next. It distills user-base expansion or contraction into a single rate, comparable across companies and time windows regardless of absolute user count. It captures the combined net effect of new-user acquisition, reactivation, and churn — but not why each moved.
Why it matters
You track user growth rate because the absolute user count tells you the size of your footprint, but the growth rate tells you whether that footprint is expanding or shrinking — and how fast. A 100,000-user product growing 2% month-over-month is on a very different trajectory than a 10,000-user product growing 15%. Operators read it as a leading indicator of product health and market demand: a slowing rate, even with stable absolute users, signals weakening acquisition, rising churn, or saturation, while a rising rate predicts future revenue scaling.
How to read it
Read it as a trend, never a single snapshot. A positive rate means acquisition and reactivation are outpacing churn; flat or negative means the leaks are larger than the inflows. Always compare this period to the prior one, to your quarterly trend, and to plan to catch acceleration or deceleration. If the rate is falling (say 20% last month, 15% this month), diagnose whether it's seasonality, a failed campaign, a product change that hurt engagement, or natural saturation. Decompose the drivers — new users added, churned users lost, reactivated users returned — to understand *why* the rate moved. And be explicit about the window: 10% month-over-month compounds to roughly 214% annual, so MoM and YoY are not interchangeable.
What good looks like
Good
Month-over-month user growth of 5–15% for mature products, or 20%+ for growth-stage applications, with positive growth across cohorts indicating healthy acquisition and retention.
Watch
Month-over-month growth below 2%, or a flat-to-declining user base while engagement metrics hold steady — a possible signal of market saturation or stalled acquisition.
Bad
Negative or zero user growth despite marketing spend; a declining base points to churn or product-market issues and demands immediate investigation into retention and new-user acquisition.
Watch-outs
- Ignoring the base. A 50% rate on 1,000 users (500 new) is very different from 5% on 100,000 (5,000 new) in absolute acquisition power. Always pair the rate with absolute user count and new-user numbers.
- Confusing month-over-month with year-over-year. A 5% MoM rate compounds to roughly 80% annually; a 15% YoY rate is only about 1.1% MoM. Be explicit about the window you're reporting.
- Counting churned-then-reactivated users as new growth. A user who churns in month 1 and returns in month 2 inflates month 2's 'new user' count but represents recovery, not true acquisition. Segment into new, returning, and net-new cohorts.
- Overlooking cohort quality. A 20% rate driven entirely by low-intent free-trial signups is fragile if retention is below 5%. Pair the rate with retention and monetization by cohort.
Worked example
Hypothetical
You close May with 50,000 active users. In June you onboard 8,000 new users but lose 3,000 to churn (no reactivations), for a closing count of 50,000 + 8,000 − 3,000 = 55,000. Your Growth Rate of Users for June is (55,000 − 50,000) / 50,000 = 0.10, or 10%.
