Marginal cost
Marginal Cost
Marginal cost (pronunciation: mahr-juh-nl kost) is a term used in Economics and Health Economics to describe the cost added by producing one additional unit of a product or service.
Etymology
The term "marginal" comes from the Latin word margo, meaning "edge" or "border". In economics, it refers to the effect of a small change in production. The term "cost" comes from the Latin constare, which means "to stand at something" or "to cost".
Definition
Marginal cost is the change in total cost that arises when the quantity produced changes by one unit. It is the cost of producing one more unit of a good. In the context of Healthcare, it can refer to the cost of providing one additional unit of a service or treatment.
Calculation
The marginal cost is calculated by dividing the change in costs by the change in quantity. The formula is as follows:
- MC = ΔTC / ΔQ
Where:
- MC is the marginal cost
- ΔTC is the change in total cost
- ΔQ is the change in quantity
