All those goods and services which have the capacity to satisfy human wants are said to contain utility in the viewpoint of economics. The relation between total and marginal utility is explained with the help of Table 1. In his estimation, the first apple is the best out of the lot available to him and thus gives him the highest satisfaction, measured as 20 utils.
Relationship Between Total Utility (TU) and Marginal Utility (MU):
The second apple will naturally be the second best with lesser amount of utility than the first, and has 15 utils. It is the representation of negative utility and total utility declines. The budget line’s slope indicates how much change in good 2 is necessary per unit of change in good 1 along the budget line. The budget constraint includes all the different combinations of goods or products that a person can afford based on the cost of goods and consumer income. Any point within the area budget line is an attainable combination that a consumer can buy given his income and price of goods.
Relationship between Total Utility and Marginal Utility
(iv) Consumption should be continuous and of some standard units. 2.Utility The want satisfying power of a good is called utility.

Therefore, total Utility, marginal Utility, and their relationship can be summarized as below.
- This will be used to calculate a commodity’s demand curve.
- The relation between total and marginal utility is explained with the help of Table 1.
- 5.Total Utility (TU) It is the sum total of Marginal Utilities derived from the consumption of all the units of a commodity.
- The capacity of a commodity to meet a need is its utility.
- The rate at which a consumer substitutes one good for another as long as the latter good is providing equal satisfaction is known as the marginal rate of substitution.

Any point outside the area is a non-attainable combination, which the consumer cannot afford to buy. The law of demand is founded on this principle, as the concept of reduced pricing is related to the Law of Diminishing Marginal Utility. 5.Total Utility (TU) It is the sum total of Marginal Utilities derived from the consumption of all the units of a commodity.

When the consumer consumes the third apple, the total utility becomes 45 utils. Thus, marginal utility of the third apple is 10 utils (45—35). Shift in demand curve occurs when the price of a commodity remains unchanged however the quantity demanded changes due to other factors, allowing the curve to shift to one side. Movement in the demand curve occurs when a commodity experiences a change in both quantity demanded and price, leading the curve to move in a specific direction.
As the consumer consumes the first unit of commodity, s/he obtains 10 utils of utility. When the consumer consumes 2nd unit of goods, TU increases to 18 utils from 10 utils and MU decreases to 8 utils. Accordingly, when the consumer consumes the 6th unit of goods, MU decreases to zero where TU becomes maximum (30 utils).
After the 6th unit consumption of goods, MU is negative (-2) and due to negative MU, total utility declines to 28 utils from 30 utils. Thus, the consumer gets maximum satisfaction when MU is zero and that point is known as the point of saturation. The marginal rate of substitution is the slope of the indifference curve.

It is worth noting that the slope of the new budget line is identical as it was before the customer’s earnings changed. Consumers are prepared to spend lesser monetary amounts for more of a product as its utility falls with increased consumption.
The capacity of a commodity to meet a need is its utility. The more the utility obtained from an item, the greater the need for it or the stronger the desire to have it. The same product can provide various levels of utility to different people. A consumer’s desire for an item is usually determined by the utility (or satisfaction) he obtains from it. It is assumed that the different unit consumed should be identical in all respects and consumption should be continuous.
When the consumer buys apples he receives them in units, 1, 2, 3, 4 etc., as shown in table 1. To begin with, 2 apples have more utility than 1; 3 more utility than 2, and 4 more than 3. The units of apples which the consumer chooses are in a descending order of their utilities. If customers want to buy one more unit of Item 1, they may only do so if they are willing to give up some quantity of another good. They must decide whether to spend money on Good 1 or Good 2.
Total utility is always based on marginal utility as a total utility (TU) is the summation of marginal utilities. The relationship between TU and MU can be explained with help of the following table. It is possible that there can be a parallel shift in the budget line. The change happens because of the change in the consumer’s income and a change in the goods’ prices. When there is a rise in consumer income, it shifts the budget line towards the right. When there is a drop in the consumer’s income, it shifts the budget line to the left.
The effects of price changes on the amount desired of an item are described in the form of a law known as the law of demand. Marginal Utility (MU) refers to additional utility on account of the consumption of an additional unit of a commodity. 6.Marginal Utility (MU) It refers to additional utility on account of the consumption of an additional unit of a commodity.
It can be seen from the above schedule that the consumer substitute X1 for X2 but continues to get the same satisfaction. But for every increase of 1 unit of when mu is falling tu is X1; the consumer gives up lesser and lesser quantity of X2.Therefore, this is called the law of diminishing marginal rate of substitution. According to the law of diminishing marginal utility, as a consumer consumes more units of a commodity, the marginal benefit received from each succeeding unit declines. In the diagram, TU is the total utility curve and MU is the marginal utility curve.
In the diagram, where the IC curve is tangent to the budget line, that is point E is the optimal choice, and also a point of consumer equilibrium. This is the point where the slope of both, the indifference curve and budget line are equal to each other. Suppose a consumer wants to consume two goods which are available only in integer units.
If there is a change in the price of one of the goods, this causes the budget line to rotate. The fall in the price causes outward radiation, which happens because there is a rise in the purchasing power of money. It asserts that when the price of an item decreases, the amount required rises, and when the price of a commodity rises, the quantity demanded declines. In other words, if everything else remains constant, the price of a commodity and its quantity requested have an inverse relationship. If we sum the utilities obtained from the consumption of different units of a particular commodity at a given time, then we get the numerical value of total utility. To draw the curves of total utility and marginal utility, we take total utility from column (2) of Table 1.
