How to Calculate Monthly Active Users (MAU) in MySQL

You will mainly need 2 columns for this purpose – user id and timestamp(when user account was created). Let’s say you have stored user information in the following table users(id, date_joined)

mysql> create table users (
id int(11) NOT NULL auto_increment,
date_joined timestamp,
PRIMARY KEY (id)
);


mysql> insert into users values
(1, '2019-12-01 2:00:00'),
(2,'2019-12-01 2:30:00'),
(3,'2019-12-02 10:00:00'),
...;

mysql> select * from users;
+----+---------------------+
| id | date_joined         |
+----+---------------------+
|  1 | 2019-12-01 02:00:00 |
|  2 | 2019-12-01 02:30:00 |
|  3 | 2019-12-02 10:00:00 |
|  4 | ...                 |
+----+---------------------+

Here’s a simple SQL query to calculate monthly active users (MAU) in MySQL for preceding month

SELECT COUNT(DISTINCT id)
    FROM users
    WHERE date_joined > NOW() - INTERVAL 1 MONTH;
+--------------------+
|         MAU        |
+--------------------+
|        1243        |
+--------------------+

You can plot the above MAU as a single number chart on your dashboard.

If you want to add some kind of filter (e.g status=4) to count only specific users, then you can add the condition to WHERE clause in the above SQL query

SELECT COUNT(DISTINCT id) as MAU
    FROM users
    WHERE date_joined > NOW() - INTERVAL 1 MONTH and status=4;
+--------------------+
|        MAU         |
+--------------------+
|        314         |

       COUNT(id) AS MAU
    FROM users
    GROUP BY LEFT(date_joined, 7);

+---------+--------+
| Month   |  MAU   |
+---------+--------+
| 2019-01 |  30100 |
| 2019-02 |  45213 |
| 2019-03 |  55301 |
| 2019-04 |  60210 |
