I see that many people still do not understand why it is so important to look at the profit and loss statement. In fact, it is a tool that helps us see the overall picture of whether a business is moving forward or slowing down.

The profit and loss statement is a financial document that shows, over a specified period, how much revenue the business has, how much expenses it incurred, and ultimately whether it made a profit or a loss. Simply put, revenue minus expenses equals profit or loss.

What I found that most people do not know is that the profit and loss statement has several levels of profit that tell different stories. For example, gross profit indicates how much we can set the selling price above the cost. Operating profit shows the direction of business management. And net profit reveals how much remains after deducting everything.

The basic principle of calculation is total revenue minus cost of goods sold to get gross profit. Then subtract various expenses such as advertising, rent, and salaries to get operating profit. After that, subtract financial expenses and taxes to arrive at the net profit, which is the final figure.

The profit and loss statement has two formats. One reports in a sequence from revenue to net profit, making it easy to read. The accounting format divides expenses on the left and income on the right, making it clear and easy to verify.

To properly read a profit and loss statement, you should first check which period you are looking at—monthly, quarterly, or yearly. Then see whether it shows a profit or a loss. Next, examine where the revenue comes from and which expenses could potentially be reduced.

The importance of the profit and loss statement is that it helps us see profit efficiency, analyze financial health, and plan strategies on how to adapt for continued growth.

However, I want to warn that investment decisions should not be based solely on the profit and loss statement. Other factors should also be considered, such as the nature of the business, the management team, and technical data supporting growth.
