Which term denotes the cost incurred by producing an extra unit beyond current production levels?

Which term denotes the cost incurred by producing an extra unit beyond current production levels?

• A. Book Costs
• B. Incremental Costs
• C. Money Supply
• D. Marginal Costs

Answer: (D)

The main idea here is the cost change when output is increased by one unit. That specific change in total cost for producing one more unit is called the marginal cost. It’s the key metric managers use to judge whether adding another unit will add enough revenue to cover its extra expense and contribute to profit. Marginal cost can vary as production scales up, due to factors like diminishing returns or changes in input costs, so it’s about the cost of the next unit, not the average or total cost. You can calculate it by looking at how total cost changes when quantity increases by one: the difference in total cost between current output and just one more unit. For example, if total cost goes from a certain amount to a higher amount when one more unit is produced, the difference is the marginal cost. The other choices don’t fit as well: book costs are historical costs already incurred, not the cost of producing an additional unit; money supply is a macroeconomic concept about the amount of money in circulation; incremental costs describe the cost of increasing output by some amount (which could be more than one unit), but the precise cost for a single extra unit is marginal cost.
