How to Get Cumulative Total Users Per Day in MySQL

Last updated on May 17th, 2020 at 06:06 am

Daily cumulative total users is a very useful KPI metric for analyzing user growth, for every business. However, since there is no built-in function to calculate running total in MySQL, here’s the SQL query to get cumulative total users per day, also known as rolling sum by date or running total of users.

 

How to Get Cumulative Total Users Per Day in MySQL

Here are the steps to get cumulative total users per day in MySQL. Let’s say you have the following table users(date_joined,user_id) that contains all the user ids with their date of registration/sign up/joining for your business.

mysql> create table users(date_joined date,user_id int);

mysql> insert into users(date_joined,user_id)
       values('2020-04-28',213),
       ('2020-04-28',214),
       ('2020-04-30',215),
       ('2020-04-28',216),
       ('2020-04-28',217),
       ('2020-04-30',218),
       ('2020-04-28',219),
       ('2020-04-28',220),
       ('2020-04-30',221),
       ('2020-05-01',222),
       ('2020-05-01',222),
       ('2020-05-01',223),
       ('2020-05-04',224),
       ('2020-05-04',225),
       ('2020-05-04',226),
       ('2020-05-04',226),
       ('2020-05-04',227),
       ('2020-05-04',228),
       ('2020-05-05',229),
       ('2020-05-05',230),
       ('2020-05-05',231),
       ('2020-05-05',232),
       ('2020-05-06',233),
       ('2020-05-06', 234);

mysql> select * from users;
+-------------+---------+
| date_joined | user_id |
+-------------+---------+
| 2020-04-28  |     213 |
| 2020-04-28  |     214 |
| 2020-04-30  |     215 |
| 2020-04-28  |     216 |
| 2020-04-28  |     217 |
| 2020-04-30  |     218 |
| 2020-04-28  |     219 |
| 2020-04-28  |     220 |
| 2020-04-30  |     221 |
| 2020-05-01  |     222 |
| 2020-05-01  |     222 |
| 2020-05-01  |     223 |
| 2020-05-04  |     224 |
| 2020-05-04  |     225 |
| 2020-05-04  |     226 |
| 2020-05-04  |     226 |
| 2020-05-04  |     227 |
| 2020-05-04  |     228 |
| 2020-05-05  |     229 |
| 2020-05-05  |     230 |
| 2020-05-05  |     231 |
| 2020-05-05  |     232 |
| 2020-05-06  |     233 |
| 2020-05-06  |     234 |
+-------------+---------+

First, we look at an SQL query to calculate the daily number of sign ups

mysql> select date(date_joined),count(user_id) 
       from users 
       group by date(date_joined);
+-------------------+----------------+
| date(date_joined) | count(user_id) |
+-------------------+----------------+
| 2020-04-28        |        6       |
| 2020-04-30        |        3       |
| 2020-05-01        |        3       |
| 2020-05-04        |        6       |
| 2020-05-05        |        4       |
| 2020-05-06        |        2       |
+-------------------+----------------+

Next, here’s the SQL query to get cumulative total users per day in MySQL. We will use the above SQL as a subquery to get running total in SQL.

mysql> set @csum := 0;

mysql> select date_joined,new_users, (@csum := @csum + new_users) as total_users
            from (
             select date(date_joined) as date_joined,count(user_id) as new_users
             from users
             group by date(date_joined)
            ) as temp
            order by date_joined;
+-------------+-----------+-------------+
| date_joined | new_users | total_users |
+-------------+-----------+-------------+
| 2020-04-28  |         6 |           6 |
| 2020-04-30  |         3 |           9 |
| 2020-05-01  |         3 |          12 |
| 2020-05-04  |         6 |          18 |
| 2020-05-05  |         4 |          22 |
| 2020-05-06  |         2 |          24 |
+-------------+-----------+-------------+

In the above query, we set a temporary variable csum to 0. Then for each row we use it to calculate and store the cumulative sum of users.

After you get cumulative total users per day in MySQL, you can plot it on a line chart or dashboard using a reporting tool like Ubiq and share it with your team. Here’s a line chart created using Ubiq.

 

If you want to get a conditional running total in MySQL, then you can add a WHERE clause in the subquery, as per your requirement.

mysql> set @csum := 0;
mysql> select date_joined,new_users, (@csum := @csum + new_users) as total_users
            from (
             select date(date_joined) as date_joined,count(user_id) as new_users
             from users 
             WHERE <condition>
             group by date(date_joined)
            ) as temp
            order by date_joined;

 

You can easily modify the above SQL query, to calculate cumulative total users by week, month, quarter and year. Let us look at them one by one. We will use DATE_FORMAT function to easily get week, month from date columns.

How to Get Cumulative Total Users Per Week in MySQL

Here’s the SQL query to get cumulative total users by week in MySQL. In the SQL query to get cumulative total users per day, you just need to change the aggregation function in subquery, from date(date_joined) to date_format(date_format,’%U’).

mysql> set @csum := 0;
mysql> select date_joined,new_users, (@csum := @csum + new_users) as total_users
            from (
             select date_format(date_joined,'%U') as date_joined,
               count(user_id) as new_users
             from users
             group by date_format(date_joined,'%U')
            ) as temp
            order by date_joined;

In the above query, you can also use WEEK function instead of DATE_FORMAT, that is, use WEEK(date_joined) instead of DATE_FORMAT(date_joined,’%U’)

            from (
             select year(date_joined) as date_joined,
               count(user_id) as new_users
             from users
             group by year(date_joined)
            ) as temp
            order by date_joined;
