Utility is the advantage and pleasure we derive from utilizing a good or service. As a result, when we eat dinner, we receive some utility that could also be called satisfaction. With that said, utility can vary. For instance, going to a pricey a la carte restaurant rather than McDonalds may be more beneficial. Utility thus gauges our preferences and the price we are willing to pay for something.
For example, you may buy an iced doughnut. You consequently gain a certain amount of utility or satisfaction from it. After that, you might decide to purchase another, gaining more utility and fulfillment The second doughnut’s utility is the Marginal Utility. In other words, the utility received above a certain point.
Chocolate producers were able to recognize this and develop a remedy. For clarification, marginal utility (MU) can decrease quickly. The Marginal Utility of their chocolates can, however, hold steady over time. In other words, whether chocolate is consumed today or tomorrow, the consumer still enjoys it. So long as consumption is spaced out.
Where did the idea of marginal utility come from?
During the nineteenth century, economists gathered to examine the idea of price. The prevailing idea was that price affected utility. They encountered a paradox, though, when they realized that some non-essential items were priced much higher than necessary ones. For instance, bread has more utility than diamonds, but diamonds are more valuable. The paradox of value was created as a result of this occurrence, and marginal utility later resolved it. Diamonds have a higher marginal utility than bread, which is less scarce, because consumers are willing to pay more for them.
What is marginal utility?
After purchasing more units of goods or services, marginal utility evaluates customer, client, and consumer satisfaction. To determine how much of a good or service consumers want to purchase, economists use marginal utility. Positive marginal utility happens when more of the same unit is consumed and total utility increases. When the opposite occurs, the product experiences negative marginal utility.
Zero marginal utility is the third common type of marginal utility. This happens when purchasing more than one of an item doesn’t increase a customer’s level of satisfaction. For instance, if a customer buys two copies of the same comic book issue and neither copy adds value, then there is zero marginal utility.
Why is marginal utility important?
Consumer decisions in the future are measured by overall product or service satisfaction.
For instance, a manufacturer of snacks might develop a brand-new sandwich cookie with an original flavor. The sandwich cookies are only distributed to test markets. After some time has passed, reviews of the product that demonstrate how much people adore it surface online. The remaining inventory quickly disappears from shelves as customers purchase multiple units at once. As a result, the manufacturer can broaden the scope of their market because this demonstrates that positive marginal utility has occurred.
The law of diminishing marginal utility
Due to its popularity, the producer enters into agreements with more suppliers, enabling the product to be sold across the country. But the law of diminishing marginal utility tempers that success. This law was developed by economists and states that as a consumer acquires more units over time, their marginal utility decreases. Consumers eventually abandon a product, much like a fad, assuming that all other factors relating to it remain the same.
How to calculate marginal utility
The value a customer places on a specific good or service can be viewed as utility. It can be summed up simply as the price a person is willing to pay for a good.
For instance, a collector of fine art discovers via social media that an auction is taking place for one of his favorite artists’ pieces. The bidder rushes to the auction and prepares to pay with a check. Although the starting bid is $800, he bids $5,000 right away to make sure he gets the piece. He gives the item more worth or value because it gives him a lot of satisfaction.
The general rule in economics is that marginal utility equals total utility change divided by change in quantity of goods. The formula appears as follows:
Total utility difference / difference in the amount of goods equals marginal utility.
1. Find the total utility of the first event
In order to calculate marginal utility, two or more events must be compared to determine an average. Add up each price if the events require valuing purchase prices to determine the utility of the first event.
2. Find the total utility of the second event
Consider information gathered from the second event. Find out how many items were modified and how much the proposed purchase would cost. To calculate the utility of the second event, add up all of your purchases.
3. Find the difference between both (or all) events
Calculate the difference between the totals from all or some of the events. The final result is the formula’s total utility difference.
4. Find the difference between the number of goods between both (or all) events
Find a total by adding all of the items you bought at the first event. Next, collect all of the items you bought for the second event (and any succeeding events). Subtract the totals from each other and reach a solution.
5. Apply the formula
After determining the two final differences, use the knowledge to update the formula. Divide both differences and set them equal to marginal utility.
Example calculation for marginal utility
During her lunch break, Dr. Avasarala heads to a nearby food truck selling tacos. Each taco only costs $2 each, but Dr. Avasarala is so hungry, shes willing to pay $5 each. She places a utility worth $5 even though the tacos only cost $2 each.
She wants to eat two tacos while she’s at the truck. She is only willing to pay $3 for the second taco because she knows she will be nearly full after the first one, putting a lower value on it. To find her total utility, she adds both totals together:
Total utility = 5 + 3
Total utility = 8
Dr. Avasarala values the two tacos at a total of $8.
On a separate visit to the food truck, Dr. Avasarala decides shes willing to eat 5 tacos. She decides the second taco is only worth $4 because she’s full after spending $5 on the first one. She would only pay $1 each for the remaining 3 tacos after the second one. She adds up all of her purchases in the second visit to determine her overall utility:
Total utility is equal to 5 4 1 1 1.
Total utility = 12
Dr. Avasarala values the five tacos at a total value of $12.
She compares the two visits’ differences to determine marginal utility.
Total utility difference = 12 – 8
Total utility difference = 4
Next, Dr. Avasarala divides the number of tacos consumed at each visit by two:
Quantity of goods difference = 5 – 2
Quantity of goods difference = 3
Dr. Avasarala has a difference of 3 tacos.
With this information in hand, Dr. Avasarala applies the formula:
Marginal utility = 4 / 3
Marginal utility = ~1.3 = 1.4
Dr. Avasarala finds she places a marginal utility of around $1. 40 on each taco.

FAQ
What is the formula for marginal utility?
The change in units can be calculated by taking the current unit amount and subtracting it from a previous unit amount. Marginal Utility = Change In Total Utility / Change In Units
How do you calculate marginal utility with example?
- Find the total utility of the first event.
- Find the total utility of the second event.
- Find the difference between both (or all) events.
- Calculate the difference in the quantity of goods between both (or all) of the occurrences.
- Apply the formula.
What is the formula to calculate utility?
The total utility is equal to the sum of utils gained from each unit of consumption, and economists calculate it using the basic total utility formula: TU = U1 MU2 MU3. Each unit of consumption in the equation is anticipated to have slightly less utility as more units are consumed.
