Implicit costs
Implicit costs (also referred to as implied, imputed or notional costs) are the opportunity costs of utilising resources owned by the firm that could be used for other purposes. These costs are often hidden to the naked eye and are not made known. Unlike explicit costs, implicit opportunity costs correspond to intangibles. Hence, they cannot be clearly identified, defined or reported. This means that they are costs that have already occurred within a project, without exchanging cash. This could include a small business owner not taking any salary in the beginning of their tenure as a way for the business to be more profitable. As implicit costs are the result of assets, they are also not recorded for the use of accounting purposes because they do not represent any monetary losses or gains. In terms of factors of production, implicit opportunity costs allow for depreciation of goods, materials and equipment that ensure the operations of a company.
