Engagement Metric

Monthly Active Users (MAU)

MAU counts unique users who perform a qualifying action at least once in a 30-day window. It's the standard top-of-funnel engagement metric for most SaaS products, and the denominator in DAU/MAU ratio (stickiness). MAU is slower-moving than DAU, making it better for trend analysis and investor reporting.

Formula
MAU = Unique users who performed a qualifying action in the last 30 days

Note: Most products define MAU on a rolling 30-day basis, not calendar month, for smoother reporting.

Healthy range

Growing MAU month-over-month with stable or improving DAU/MAU ratio

Warning signs

MAU growing while DAU/MAU declines = top-of-funnel growth masking engagement decay

Benchmarks by segment

Early-stage SaaSFocus on retention quality, not MAU absolute
Growth-stage SaaS10–20% MoM MAU growth is strong
Mature SaaS5–10% MoM MAU growth; focus shifts to ARPU

How to improve MAU

1

Improve activation — users who reach the aha moment in week 1 are 3–5× more likely to remain MAU

2

Reduce time-to-value in onboarding to ensure new users qualify as active before churning

3

Win-back campaigns for users who were MAU last month but not this month

4

Expand within accounts — adding seats grows MAU without acquisition spend

Common measurement mistakes

!MAU can stay flat while your most valuable users churn (if replaced by lower-value users)
!Different MAU definitions across teams make period-over-period comparison unreliable
!Paying for MAU growth through discounts or giveaways creates false engagement signals

Frequently Asked Questions

What's a good MAU/total registered users ratio?

There's no universal benchmark, but < 20% suggests most registered users are dormant. Focus on improving this ratio before scaling acquisition.

How does MAU relate to revenue?

For freemium products, MAU is the top of your conversion funnel. For usage-based pricing (Amplitude, Mixpanel), MAU directly drives revenue. For seat-based SaaS, MAU is a health signal — it doesn't map directly to ARR.
