Explanation:

There are many cost classifications when the impact of costs on profits are to be calculated.  In this example, we shall discuss the following:

a) Explicit Costs: These are the costs which a business incurs by running the organisation.  They usually and directly affect profitability.  Every business tries to minimize such costs.  Example is the cost of Wages and Salaries paid to employees.

b) Implicit Costs:  These costs are opportunity costs incurred when a business pursues an alternative decision vis-a-vis another or uses its own internal resources instead of paid resources.  They are usually calculated for decision making purposes.  An example is the cost of rent that could have been incurred if the asset is not internally sourced.

c) Economic Costs:  These are costs that include both actual and opportunity costs.  It tries to weigh all costs, including the costs for pursuing alternative courses of action.
