When the marginal utility comes to zero or we say the point of satiety is reached, the total utility is the maximum. If consumption is increased further from this point of satiety, the marginal utility becomes negative and total utility begins to diminish. The relationship between total utility and marginal utility is now explained with the help of following schedule and a graph.
Utility measures the benefits (or drawbacks) from consuming a good or service or from working, and although utility is not directly measurable, it can be inferred from the decisions that people make. In economics, marginal utility is usually described by a function, such as the exponential utility function. In measuring the utility of a certain good, service, or labor, economics use either expected or indirect utility to express the amount of pleasure from consuming or purchasing an object.
