Marginal utility of money reflects the additional satisfaction or benefit derived from holding an additional unit of money. It can be calculated using the formula: ΔU/ΔM = dU/dM, where ΔU represents the change in utility, ΔM represents the change in the amount of money held, and dU/dM is the derivative of the utility function with respect to money. This formula measures the rate at which utility increases as income or wealth increases, providing insights into how individuals value money and their willingness to consume or save.
Marginal Utility of Money Formula
The marginal utility of money is the additional satisfaction or benefit derived from consuming an additional unit of money. It’s the value people place on the extra money they earn.
Diminishing Marginal Utility
The law of diminishing marginal utility states that the more of a good or service you consume, the less additional satisfaction you get from each additional unit. This applies to money as well.
Factors That Affect Marginal Utility of Money
- Income: The higher your income, the lower the marginal utility of money.
- Wealth: The more assets you have, the lower the marginal utility of money.
- Needs: The more your basic needs are met, the lower the marginal utility of money.
- Preferences: Different people value money differently based on their preferences.
Marginal Utility Formula
| Variable | Description |
|---|---|
| ΔU | Change in Utility |
| ΔM | Change in Money |
The marginal utility of money can be measured using the following formula:

MU = ΔU / ΔM

Marginal Utility of Money Formula
The marginal utility of money refers to the additional satisfaction or benefit an individual derives from holding an additional unit of money. The formula for calculating marginal utility of money (MUM) is as follows:
- MUM = ΔTU / ΔM
where:
* ΔTU is the change in total utility
* ΔM is the change in the amount of money
This formula demonstrates that the marginal utility of money is the ratio of the change in total utility to the change in the amount of money held.
Indifference Curves
Indifference curves are graphical representations of combinations of goods or services that yield the same level of satisfaction or utility to a consumer. In the case of the marginal utility of money, indifference curves can be used to illustrate the relationship between the amount of money held and the total utility derived from it.
Consider the following table, which shows the indifference curve for an individual’s marginal utility of money:
| Amount of Money | Total Utility |
|---|---|
| $100 | 50 |
| $200 | 75 |
| $300 | 90 |
As the amount of money increases, the total utility also increases, but at a decreasing rate. This is because the marginal utility of money decreases as more money is acquired. This can be seen in the graph of the indifference curve below:
The slope of the indifference curve represents the marginal utility of money. As the amount of money increases, the slope of the curve decreases, indicating that the marginal utility of money is diminishing.
Economic equilibrium
In economics, equilibrium is reached when the supply of and demand for a good or service are equal. The equilibrium price is the price at which the quantity of a good or service that is supplied is equal to the quantity that is demanded. In the context of money, equilibrium is reached when the amount of money in circulation is equal to the amount of goods and services that are being produced.
The utility of money formula is a mathematical equation that can be used to determine the equilibrium price of money. The formula is as follows:
M * V = P * Q
where:
- M is the quantity of money in circulation
- V is the velocity of money, which is the number of times that a unit of money is used to purchase goods or services
- P is the price level, which is the average price of all goods and services in an economy
- Q is the quantity of goods and services that are being produced
Example
For example, if the quantity of money in circulation is $100 billion, the velocity of money is 4, the price level is $500, and the quantity of goods and services that are being produced is 200 million units, then the equilibrium price of money would be $125,000,000/$100,000,000 = 1.25. This means that each unit of money would be worth 1.25 units of goods and services.
The utility of money formula can be used to predict the effects of changes in the quantity of money in circulation. For example, if the government increases the quantity of money in circulation, then the price level will increase and the value of each unit of money will decrease. This is because the increase in the quantity of money will lead to an increase in the demand for goods and services, which will in turn lead to an increase in prices.
