📊 Monthly Active Users (MAU) Calculator
How to Use This Tool
Select your preferred calculation method from the dropdown: choose Growth-Based if you track user acquisition and churn, or Direct Count if you have a pre-calculated MAU figure.
For Growth-Based method: enter your total users at the start of the month, new users acquired, and churned users. For Direct Count method: enter your manually verified unique active users for the month.
Optionally add an industry benchmark to compare your MAU against standard performance for your sector.

Formula and Logic
The calculator uses two methods depending on your selected input:
- Growth-Based Method: MAU = (Start of Month Users) + (New Users Acquired) - (Churned Users). Net Growth = New Users - Churned Users. Retention Rate = ((Start Users - Churned Users) / Start Users) * 100.
- Direct Count Method: MAU equals the exact unique user count you provide. Net Growth and Retention Rate are marked as N/A since acquisition and churn data is not included.
Benchmark comparison calculates the percentage difference between your MAU and the industry benchmark you provide.
Practical Notes
For e-commerce and SaaS businesses, a healthy MAU retention rate ranges between 30-50% for consumer apps and 70-90% for B2B platforms. Use this tool monthly to track trends rather than day-to-day fluctuations.
- Churned users are defined as unique users who had no engagement with your product or service in the current 30-day period.
- Industry benchmarks vary: e-commerce averages 2-5% monthly growth, while SaaS platforms target 5-10% growth for early-stage businesses.
- Combine MAU data with average revenue per user (ARPU) to calculate total monthly recurring revenue (MRR) for your business.
Why This Tool Is Useful
MAU is a core metric for digital businesses to measure user engagement and product-market fit. This tool eliminates manual calculation errors and provides a detailed breakdown to inform retention and acquisition strategies.
Marketing teams can use MAU trends to adjust campaign spend, while business owners can benchmark performance against industry standards to secure funding or partnerships.
Frequently Asked Questions
What counts as an active user for MAU?
An active user is any unique individual who completes a meaningful action in your product or service within the 30-day period, such as logging in, making a purchase, or viewing a page. Exclude bot traffic or test accounts from your counts.
How often should I calculate MAU?
Calculate MAU at the end of each calendar month to maintain consistent tracking. Avoid overlapping periods or adjusting the 30-day window, as this will skew year-over-year comparisons.
Why is my retention rate showing as N/A?
Retention rate is only calculated for the Growth-Based method, which requires start-of-month user and churn data. Switch to Growth-Based calculation and enter the required inputs to view retention metrics.
Additional Guidance
Segment your MAU by user type (e.g., free vs paid, new vs returning) to identify high-value user groups. Pair this tool with weekly active user (WAU) calculations to get a more granular view of engagement.
If your business has seasonal fluctuations (e.g., holiday e-commerce sales), compare MAU to the same month in the previous year rather than the prior month to account for seasonal trends.
