What is a Monthly Active User (MAU)?

Quick Definition: Monthly Active User (MAU) is a key performance metric that measures the total number of unique users who engaged with an application at least once during a 30-day period. It is a high-level indicator of an app’s total audience size and overall “stickiness.”

An Introduction to Monthly Active Users

MAU is one of the most common metrics used to gauge the health and scale of a mobile app, social network, or subscription service. While Daily Active Users (DAU) measures daily engagement, MAU provides a broader, 30-day view of your app’s total “active” user base. It answers the question, “How many unique people used my app at least once this past month?”

This metric is crucial for understanding the overall reach and retention of your app. A user who logs in one time during the month is counted the same as a user who logs in every day—they both count as one Monthly Active User. This makes MAU a great measure of an app’s ability to retain users month-over-month and its total potential audience for monetization.

How MAU Works: An Example

Let’s look at an app’s user behavior during the 30 days of November:

• User A: Logged in every single day.
• User B: Logged in only on November 1st and never came back.
• User C: Logged in 5 times, all in the last week of the month.
• User D: Last used the app on October 30th and did not open it in November.

For the month of November, the app’s Monthly Active User (MAU) count is 3 (User A, User B, and User C). User D is not counted as an MAU for November because they had no sessions during the 30-day period.

Why are Monthly Active Users (MAU) Important

Measures App “Stickiness” (DAU/MAU Ratio): This is the most famous use of MAU. By dividing your DAU by your MAU, you get the “stickiness ratio,” which shows what percentage of your monthly users are engaged enough to come back every day. It’s a powerful measure of retention.

Indicates Overall App Health & Scale: MAU is a stable, high-level metric that shows the overall size of your active user base. A growing MAU indicates your marketing and product are successfully attracting and retaining users over time.

Valued by Investors: Along with DAU, MAU is a key metric that investors and stakeholders look at to judge an app’s market penetration, growth trajectory, and overall scale.

Calculates Total Monetization Potential: Your MAU represents your total monetizable audience for the month. It’s a foundational number for calculating other key metrics like Average Revenue Per User (ARPU).

The GoKart Advantage: Connecting MAU to Long-Term Value

A high MAU represents a large, addressable audience for your monetization strategy. The GoKart platform helps you monetize your full audience, including users who log in only a few times monthly.

• Monetize Casual Users: Many users in your MAU count are not daily “power users.” GoKart’s Offerwall and Offer Program features are perfect for these users. They can log in, see a high-value, relevant offer, and choose to engage with it, allowing you to generate significant revenue from users who don’t log in daily.
• Focus on LTV, Not Just DAU: GoKart helps you think in terms of long-term value. By providing a positive, opt-in ad experience, you reduce the risk of annoying and “churning” your monthly active users. This keeps your MAU count stable and high, maximizing the Lifetime Value (LTV) of your entire user base, not just your daily visitors.
• Drive Re-engagement: A fresh, valuable Offerwall gives your monthly users a compelling reason to come back. It’s not just an ad; it’s a feature. This can help convert casual monthly users into more engaged, daily active users.
