Operating Income vs. Non-Operating Income – A Comparative Study

Last Updated Date - Mar 25, 2023

Below is a comparison between operational income vs non-operating income:

There are two basic forms of income that a business might generate: operational income and non-operating income.

Non-operating income is the revenue produced by a company’s ancillary or auxiliary operations, whereas operational income is the revenue produced by a company’s primary business operations.Operating Income vs. Non-Operating Income


  • Operational income is the money the firm makes from its main lines of activity. The proceeds from the sale of products or services less the cost of goods sold, operational costs, and depreciation are included in this.
  • The revenue derived from outside the company’s primary business operations is known as non-operating income. This involves profits from the sale of assets, rental income, and income from investments.


  • Operational income is a crucial indicator for assessing the profitability of a business’s main lines of operation. It aids investors in determining how well the firm is running its business and earning revenue.
  • Non-operating income is crucial for understanding a company’s total financial performance. By considering all revenue streams, it gives a more complete view of the company’s financial health.


  • Compared to non-operating revenue, operational income is often seen as being more stable. This is because it is strongly linked to the company’s core operations and is less influenced by outside variables.
  • Non-operating income is more variable than operational income because it is affected by external factors such as market changes and economic circumstances.


  • Operational income is subject to corporate income tax, whereas non-operating income may be taxed differently depending on its source.
  • Investment income, for example, may be liable to capital gains tax, whilst rental income may be subject to property tax.

Growth Potential

  • Operational income has limited development potential because it is closely related to the company’s key business operations.
  • If the business expands into new markets, non-operating income may offer other sources of revenue and may have a larger potential for development.

    Importance of Operating Income vs. Non-Operating Income

    Operating income and non-operating income are crucial metrics in the financial analysis since they aid in understanding a company’s profitability and overall financial performance.

    Following are some reasons for the importance of both operating and non-operating income in financial analysis:

    Profitability Analysis

    Operational income is a crucial indicator for understanding the profitability of a company’s fundamental business operations.  It aids in finding out whether the company’s income is sufficient to pay its costs of operation and turn a profit.

    Consequently, non-operating income shows how successfully a corporation may bring in money from sources other than its primary business operations.

    Trend Analysis

    Identifying patterns in a company’s financial performance can be aided by comparing operating income and non-operating income across time.

    A decrease in operational income, for example, may show that the firm’s main business operations are not generating enough money. But an increase in non-operating income may show that the organization is controlling its revenue streams.

    Analysis of Investments

    Operational income and non-operating income are crucial variables for investors to assess a company’s financial stability and make wise investment decisions.

    Operational income shows a company’s capacity to make money from its main business operations. But non-operating income can add to operating income and diversify a company’s revenue sources.

    Risk Evaluation

    As non-operating income depends on outside variables like market circumstances and economic trends, it may be more erratic than operational revenue.

    So, comprehension of a company’s non-operating income can aid in understanding the possible dangers related to investing in the business.


    For judging the financial performance of other businesses operating in the same sector, operational income and non-operating income are helpful measures.

    By comparing operational income versus non-operating income, investors may assess which firms are producing the most money. That comes from their main business operations and companies.

    How to Calculate Operating Income vs. Non-Operating Income

    A company’s financial information is needed to determine operating income and non-operating income. These two sources of revenue may be determined as follows:

    Operational Income

    Operating income is determined by deducting operating costs and the cost of goods sold from the revenue derived from the company’s primary business operations. The formula for understanding operational income is as follows:

    Operating Income = Revenue – Cost of Goods Sold – Operating Expenses

    • Revenue: The total amount of money earned through the selling of products or services.
    • Cost of Goods Sold (COGS): The total expense in producing or getting the products or services sold.
    • Operational Expenses: These expenses include salary, rent, and other costs involved with understanding the company’s main business activities.

    Non-Operating Income

    Therefore, Non-operating income is determined by aggregating all revenue got from sources outside of the company’s primary business operations. Non-operating income is determined using the following formula:

    Non-Operating Income = Other Revenue + Investment Income + Gains from the Sale of Assets

    • Other Revenue: The total revenue got from sources other than the company’s primary business activity, such as rental income.
    • Investment Income: The revenue the business receives from the sale of its stocks, bonds, or other financial holdings.
    • Gains from the Sale of Assets: The revenue got through the sale of assets, such as real estate, machines, or other assets, which are not needed for the company’s primary business activities.


    When understanding a company’s financial performance and overall standing among its peers, operational income and non-operating income are both important.

    They offer correct information on a company’s profitability, tactics, and general financial health. To completely understand a company’s financial performance, analysts and investors need carefully examine both sources of income.

    And therefore, it is crucial to take into account both sources of revenue. In the context of the particular facts as well as the aims of the organization when making decisions or judging a company.
