total cost curve
The total cost curve graphically represents the relation between total cost and the quantity of production. This curve can be derived in two ways. One is to plot a schedule of numbers relating output quantity and total cost. The other is to vertically add the total variable cost curve and the total fixed cost curve.he total cost curve is frequently used with a total revenue curve to determine the profit maximizing level of production for a firm. However, this curve is perhaps most important as the basis for deriving the average total cost curve and the marginal cost curve.
