It is important to draw the distinction between marginal utility and total utility. When we consume a certain quantity of a given good, the total satisfaction or happiness we gain from that consumption is the total utility. Marginal utility is a derivative of utility, and utility is simply the satisfaction we get from consuming a given good. This is the quick definition of marginal utility, but let's explain the concept in more detail. Marginal utility is defined as the additional satisfaction you get from consuming an extra unit of a given good. Dive in to learn more! Marginal Utility Definition But do you continue to crave the drink the same way once you begin to drink it? No! With each sip, you crave to drink less until you finally stop drinking, which is a sign that you have had enough of it! This article about marginal utility explains this phenomenon of additional satisfaction and helps you understand why we behave the way we do as consumers.

Before you get your hands on a can of soda, your craving for the drink is at its highest, and so is your satisfaction when you finally get a sip. The concept of marginal utility explains this. Given that we can afford more, why do we stop drinking our favorite soda after drinking a certain quantity of it? One might say we stop drinking when we have had enough of it, and this is not wrong.

This isn't a negative MU but it still decreases the total utility because it's not worth the cost.

The concept of marginal utility is used by economists to determine how much of an item consumers are willing to purchase. It's possible for goods to give some benefit to the consumer without being 'worth it.' For instance, the fifth ticket in the chart above still gives $2 worth of MU. Marginal utilityis the added satisfaction that a consumer gets from having one more unit of a good or service. Note that utility isn't necessarily maximized when the MU starts to become negative.The next ticket after this has an MU of $2, which is less than the marginal cost of $3. In this case, utility is maximized when the consumer buys 4 tickets. Let's say that the tickets in the example chart cost $3 each.If you know how much the goods being analyzed in the chart cost, the point where utility is maximized is the last row where MU is higher than the marginal cost. As a reminder, consumers tend to buy goods until the marginal price (the cost of one more unit of the goods) is greater than the MU. Because households divide their incomes between consumption expenditures and saving, the sum of the propensity to consume and the propensity to save will always equal one. A marginal utility chart makes it easy to predict how many units of goods a consumer will buy. In propensity to consume income is known as the marginal propensity to consume. This is the point where marginal price exceeds MU.
