Total utility (TU) and Marginal Utility (MU): Total Utility (TU) Definition and Explanation “Total utility is the total is the total satisfaction obtained from all units of a particular commodity consumed over a period of time”. The shape of the demand curve, its decreasing slope, and its convexity towards origin, is precisely the consequence of the analysis of marginal utility: by increasing the quantity demanded, its marginal utility is decreasing, so we will be willing to pay each time less money for the product. The marginal utility of money, like that of any other good, is decreasing. Most people would argue that more is always better. For example, when a person increases the consumption of eggs from one egg to two eggs, the total utility increases from 30 utils to 45 utils. Consumer tastes and balance can also be demonstrated by indifference curves. In doing so, the width of each step would be reduced to a single point and the ladder would become a curved line. As a general rule, MU is equal to the change in total utility divided by the change in the quantity of goods consumed. If I have four chocolate bars, you could say the total utility I'm getting from all four of them. All points on the same indifference curve provide identical consumer satisfaction. Or, you could think about marginal utility, the utility I'm getting from the next incremental chocolate bar or the next incremental pound of fruit.
