    Understanding the Concepts of Accounting Terms for Income and Expenses


    A segregated list of the accounting definitions of income and expense terminologies furnishes the reader with a more organized resource for looking up meanings. As one is allowed to stay focused with the income and expense related terminologies, the learner will find it easier to grasp the principles and concepts related to cost incurrence and revenue generation.

    Basically, income and expense accounts are classified as nominal accounts, which denote that their nature is temporary and that their account titles are based on the appropriate descriptions for a particular transaction.

    At the end of the accounting period, these nominal accounts will be zeroed-out and are transferred to the Profit and Loss Summary. This is where the result of the business operations is determined as favorable or not, either as a Net Income or Net Loss. Once this has been established, the resulting amount will be taken up as an increase or decrease of the Capital (Single Proprietorships) or the Retained Earnings accounts.
