Cost refers the monetary measure of the amount of resources given up or used for some specified purpose. It is the value the goods or services expended to obtain current or future benefits.
Costs can be classified in different ways. There are manufacturing costs and non-manufacturing costs, direct and indirect costs, product and period costs, controllable and uncontrollable costs, fixed and variable, etc.
