5.a. Total Cost and Total Benefit Total Cost It is the cost of producing a certain number of units of a good. Graphically, it can be expressed as the area underneath the supply curve up to the quantity produced. See Figure 5.a.1 below. Figure 5.a.1: The total cost to produce the first unit of the good is \$1 (Area 1). The cost of producing an additional unit of the good is an additional \$2 (Area 2) for a total cost of \$3 (Area 1 +Area 2) to produce a total of 2 units. If the producer wanted to producer a third unit, the additional cost of producing that extra unit would be \$3 (Area 3). The total cost of producing 3 units of the good would be Area 1 + Area 2 + Area 3 or \$1 + \$2 + \$3 = \$6. NOTE: The amount that it costs to produce one more unit of a good is known as marginal cost (each individual area). Hence: Total Cost = Sum of Marginal Costs. 1 2 3 4 \$1 \$2 \$3 \$4 Q P Supply Area 1 Area 2 Area 3
