In 2011, the marginal cost of production for oil was $92.26 for the 50 largest listed oil and gas companies, according to the Wall Street Journal.This will climb to $100 a barrel in 2012.n 2011, the marginal cost of production for oil was $92.26 for the 50 largest listed oil and gas companies, according to the Wall Street Journal.
Example: For example, the total cost of producing one pen is $5 and the total cost of producing two pens is $9, then the marginal cost of expanding output by one unit is $4 only (9 - 5 = 4).The marginal cost of the second unit is the difference between the total cost of the second unit and total cost of the first unit.The marginal cost of the 5th unit is $5. It is the difference between the total cost of the 6th unit and the total cost of the, 5th unit and so forth.Marginal Cost is governed only by variable cost which changes with changes in output. Marginal cost which is really an incremental cost can be expressed in symbols.hen average total cost curve begins to rise, marginal cost curve also rises, passes through the minimum point of the average cost and then rises. The only difference between the short run and long run marginal cost and average cost is that in the short run, the fall and rise of curves LRMC is sharp.
