What is the best definition of marginal benefit?

The best definition of marginal benefit can be stated as the additional satisfaction or utility that a person receives from consuming an additional unit of a good or service, all other factors being equal. In other words, marginal benefit is the advantage or benefit gained by increasing the quantity of consumption or use of a particular commodity or service by one unit. It is important to note that marginal benefit can vary from person to person and from situation to situation, depending on factors such as personal preferences, income, and the availability of substitutes. Understanding marginal benefit is vital for making informed decisions, especially in economic and business contexts where decisions are often based on cost-benefit analysis.
