In the fields of finance and economics, the term "net income" is well recognized.

Let's study more about the idea, contributing variables, definition, and computation of net income down below.

1. What is net income?

Net Income: What Is It? The amount left over after all costs and taxes are subtracted from a company's gross profit or total revenue is called net income, sometimes referred to as profit after taxes or net profit. It is frequently employed to assess the financial performance of an organization over a given time frame.

A key metric in financial statements, net income is frequently used to compute other metrics like earnings per share and profit margin. The business deducts all costs from total revenue or gross profit to determine net income. These costs include interest, corporate income taxes, operational, sales, and administrative expenses, among other costs.

2. Standard Net Income calculation and specific examples

Standard Net Income calculation

  • Net Income = Total revenue - Total costs

In which:


  • Total revenue = Net revenue + Profit from financial activities + Bonus income.
  • Total costs = Cost of products/goods + Business operating costs + Corporate income tax payable + Other costs.
  • Other costs include: sales costs, business management costs, marketing costs, depreciation costs, and other incurred costs.


For example:

Suppose the financial statements of a confectionery company in the second quarter of 2023 are:

  • Revenue: 10 billion VND.
  • Equity and other income: 800 million VND.
  • Cost of sales (including costs of materials and direct labor): 4 billion VND.
  • Operating costs 3 billion VND.
  • Loan interest: 600 million VND.
  • Income tax: 980 million VND.
  • Other costs 500 million VND.


So the net income of this company is:

Net Income = (10,000,000,000 + 800,000,000) - (5,000,000,000 + 3,000,000,000 + 600,000,000 + 980,000,000 + 500,000,000) = 1,720,000 (VND).

Net Income Characteristics

Revenue less all expenses and losses incurred during an enterprise's business and manufacturing processes equals net income. In the event that this index is negative, it indicates a net loss for the company. Effective business operations are indicated by a positive index.

The net income of a company affects the growth of its profits. As a result, shareholders' capital rises as well. As a result, when a company experiences a net loss, shareholders' capital drops as well.

Note: Business gains and losses may not be included in this computation of net income.

What factors affect Net Income?

  • Operating costs of the business: This cost includes all costs of the business such as: business management costs, marketing costs, depreciation costs, etc. The higher the cost, the higher the index. Net Income will be lower. At that time, businesses need to establish marketing solutions and management solutions to aim at reducing costs and increasing business efficiency.
  • Cost of goods: The lower the cost of goods sold index, the higher the Net Income. Therefore, businesses need to find ways to diversify product sources to have low cost prices while still ensuring product quality.

Impact of Net Income on individuals 

Net Income from a personal perspective represents a person's level of spending and their excess financial situation.

5. Meaning of Net Income for individuals and businesses

For individuals

From a personal standpoint, net income is significant since it aids in monitoring and modifying daily spending. When your net income is negative, you need to cut back on wasteful spending and look for methods to boost your revenue. If your net income is positive, you are following a sensible spending plan, which you should keep up in order to improve your income and standard of living.

For businesses

Because investors are particularly interested in this index, net income is an index that helps firms draw in capital. Investors will value the company if the Net Income index is positive since it indicates growth potential. Investors, however, will be reluctant to invest heavily in that company if this index is negative. Due to the fact that firms declare losses frequently, they are vulnerable to financial crises and investment risks increase.

For investors

Investor attention is always focused on net income since it is a crucial metric that illustrates the profit a company makes after all costs are subtracted. Investors are primarily concerned with a company's net income and pay little attention to the inner workings of the organization. Consequently, it is crucial to keep your net revenue steady if you are trying to find investors for your company.
