What is Monthly Active Users?
Monthly Active Users (MAU) is a metric that counts the number of unique users who engage with a SaaS product at least once during a given month. It is a key indicator of user engagement, product adoption, and overall business health.
Why Does Monthly Active Users Matter for SaaS Companies?
- Measures the breadth of user engagement on a monthly basis
- Tracks product adoption and growth in the active user base
- Supports calculation of engagement ratios like DAU/MAU (stickiness)
- Guides product improvements and retention strategies
- Commonly used by investors to assess traction and growth potential
How is Monthly Active Users Calculated?
MAU = Number of unique users who performed at least one meaningful action in the product during the month. Example: 10,000 unique users logged in and used a feature in March = MAU of 10,000.
Example:
- Count each unique user only once regardless of login frequency
- Define \’active\’ as performing a meaningful product action, not just logging in
- Track MAU monthly and compare month-over-month for trends
