Marginal cost is a production and economics calculation that tells you the cost of producing additional items. You must know several production variables, such as fixed costs and variable costs in order to find it. You can learn how to find marginal cost by using a formula.ake a column to the right of total cost that says Marginal Cost.  Your first line in the column will remain blank, because you cannot figure out a marginal cost based on no units of production.
