Question

What is the definition for marginal cost, and how is it calculated? I’d like to understand how marginal cost helps businesses evaluate the additional cost of producing one more unit of a product or service.

Marco · Answer

Marginal cost is the extra cost incurred from producing one additional unit of a good or service. It’s calculated as the change in total cost divided by the change in quantity produced: MC = ΔTotal Cost / ΔQuantity. Businesses use it to decide whether producing more makes sense — if the marginal cost of an extra unit is lower than the revenue it brings in, it’s profitable to produce it. Monitoring marginal cost also helps identify the most efficient production level, since costs often rise after a certain output point due to resource constraints or diminishing returns.
