Review of Cost and Revenue Curves
The Concept of Cost
Costs are expenses incurred during production. We shall examine the following types of cost incurred during process of production.
This is made up of total fixed cost and total variable cost, i.e. TC = TFC + TVC, where TFC is total fixed cost and TVC is total variable cost
Total Fixed Cost
These are the costs that do not change with the level of production. They remain constant whether the firm is working at full capacity or not. Examples are rent, purchase of equipment and machinery, top management salary. These expenses are usually fixed in the short run.
Mathematically, TFC = TC – TVC
Total Variable Cost
These are expenses that vary as output increases or decreases.
