It is important to calculate revenue for every business. Here’s how to calculate revenue in MySQL. You can use it to calculate daily revenue, month by month revenue, year by year revenue, revenue for last 12 months, for current month and more. We will look at each use case in detail.

 

How to Calculate Revenue in MySQL

Here are the steps to calculate revenue in MySQL.

Let’s say you have 2 tables products(product_id, product_name, price) and orders(order_date,product_id, quantity). 

mysql> create table products(product_id int,product_name varchar(255),price int);
mysql> insert into products(product_id,product_name,price) 
       values(1,'iPhone 11',400),(2,'Samsung Galaxy A50',250);

mysql> select * from products;
+------------+--------------------+-------+
| product_id | product_name       | price |
+------------+--------------------+-------+
|          1 | iPhone 11          |   400 |
|          2 | Samsung Galaxy A50 |   250 |
+------------+--------------------+-------+


mysql> create table orders(order_date date,product_id int,quantity int);

mysql> insert into orders(order_date,product_id,quantity) 
       values('2020-05-01',1,23),('2020-05-01',2,35),
       ('2020-05-02',1,45),('2020-05-02',2,23),('2020-05-03',1,19),
       ('2020-05-03',2,15),('2020-05-04',1,34),('2020-05-04',2,56);

mysql> select * from orders;
+------------+------------+----------+
| order_date | product_id | quantity |
+------------+------------+----------+
| 2020-05-01 |          1 |       23 |
| 2020-05-01 |          2 |       35 |
| 2020-05-02 |          1 |       45 |
| 2020-05-02 |          2 |       23 |
| 2020-05-03 |          1 |       19 |
| 2020-05-03 |          2 |       15 |
| 2020-05-04 |          1 |       34 |
| 2020-05-04 |          2 |       56 |
+------------+------------+----------+

For our example, revenue per order is basically price * quantity. We will look at different use cases to calculate revenue in MySQL

 

How to Calculate Daily Revenue in MySQL

Here’s the SQL query to calculate daily revenue in MySQL.

mysql> select date(order_date),sum(price*quantity) 
from products,orders 
where products.product_id=orders.product_id 
group by date(order_date);
+------------------+---------------------+
| date(order_date) | sum(price*quantity) |
+------------------+---------------------+
| 2020-05-01       |               17950 |
| 2020-05-02       |               23750 |
| 2020-05-03       |               11350 |
| 2020-05-04       |               27600 |
+------------------+---------------------+

In the above SQL query, we multiply price x quantity to calculate revenue per order. Since price & quantity are in different tables, we join products and orders tables using the condition product.product_id=orders.product_id. Then we GROUP by DATE function to aggregate order revenue and get daily revenue.

After you calculate revenue in MySQL, you can use a reporting tool to plot this data on a bar chart or dashboard and share it with your team. Here’s an example of a bar chart that shows daily revenue, created using Ubiq.

How to Calculate Month By Month Revenue in MySQL

Here’s the SQL query to calculate total revenue per month in MySQL. You just need to replace DATE function in above query with MONTH function

mysql> select month(order_date),sum(price*quantity) 
from products,orders 
where products.product_id=orders.product_id 
group by month(order_date);
+------------------+---------------------+
| month(order_date)| sum(price*quantity) |
+------------------+---------------------+
|          1       |              127950 |
|          2       |              223750 |
|          3       |              311350 |
|          4       |              427600 |
+------------------+---------------------+

The above query will display month numbers with their revenue alongside. If you want to display month names, use DATE_FORMAT function

mysql> select date_format(order_date,'%b'),sum(price*quantity) 
from products,orders 
where products.product_id=orders.product_id 
group by date_format(order_date,'%b');
+------------------+---------------------+
| month(order_date)| sum(price*quantity) |
+------------------+---------------------+
|        Jan       |              127950 |
|        Feb       |              223750 |
|        Mar       |              311350 |
|        Apr       |              427600 |
+------------------+---------------------+

How to Calculate Revenue for Last 12 months in MySQL

Here’s the SQL query to calculate monthly revenue for last 12 months. You can use INTERVAL function to calculate revenue in MySQL, for last 12 months.

from products,orders 
where products.product_id=orders.product_id 
and order_date > now() - INTERVAL 12 month 
group by month(order_date);

In the above query, we filter data that is after a past interval of 12 months.
