# Explain relationship between average cost and marginal

### Relation between Average, Marginal and Total Cost | Production | Microeconomics

There is a difference between average cost and marginal cost. 1 educator answer; What is the relationship between marginal costs and variable costs? cost is also defined as the sum of average fixed cost and average variable cost. Relationship between Marginal Cost (MC) and Average Cost (AC) is stated below: (i) When AC falls, MC zolyblog.info than AC. (ii) When AC rises. Relation between AC & MC Average Cost is simply the total cost (TC) divided by the number of units produced (Q) or it is per unit cost. On the.

It shows that so long as the marginal cost curve lies below the average cost curve, the average cost falls pulled downwards by the marginal cost.

On the other hand, when marginal cost lies above the average cost curve, the average cost rises pulled upwards by the marginal cost. When marginal cost is equal to average cost, it is the minimum point of the latter.

It is important to note that as long as the marginal cost is less than average cost, each additional unit of output will add less to total cost in comparison to the average per unit cost incurred on the previous units. This lowers the overall average cost of production. Hence, the average cost will continue to decline as long as the marginal cost is less-than the average cost whether the marginal cost is itself rising or falling.

Further, when the marginal cost exceeds the average cost, each extra unit of output produced adds more to the total cost than the average cost incurred on the previous units, resulting in rise in the overall average cost of production. This leads to a rise in the average cost curve, when the marginal cost is more than the average cost.

Finally, if the additional unit of output produced costs same as the average cost incurred on the previous units, the overall average cost does not change and attains its minimum value.

Thus, when the average cost reaches its minimum level, it is equal to the marginal cost. If instead of 45, he scores more than 50, say 55, in his next innings, then his average score will increase because now the marginal score is greater than his previous average score.

4.6 The Relationship Between Average Total Cost and Marginal Cost

Again, with his present average runs of 50, if he scores 50 also in his next innings, then his average score will remain the same because now the marginal score is just equal to the average score. Likewise, suppose a producer is producing a certain number of units of a product and his average cost is Rs.

Now, if he produces one unit more and his average cost falls, it means that the additional unit must have cost him less than Rs.

On the other hand, if the production of the additional unit raises his average cast, then the marginal unit must have cost him more than Rs. And finally, if as a result of production of an additional unit, the average cost remains the same, then marginal unit must have cost him exactly Rs. The relationship between average and marginal cost can be easily remembered with the help of Fig.

It is illustrated in this figure that when marginal cost MC is above average cost ACthe average cost rises, that is, the marginal cost MC pulls the average cost AC upwards. On the other hand, if the marginal cost MC is below the average cost AC ; average cost falls, that is, the marginal cost pulls the average cost downwards.

• What is the Relationship between Average Cost and Marginal Cost? – Explained!

When marginal cost MC stands equal to the average cost ACthe average cost remains the same, that is, the marginal cost pulls the average cost horizontally. As long as short-run marginal cost curve MC lies below short-run average cost curve, the average cost curve AC is falling.

## What is the Relationship between Average Cost and Marginal Cost?

When marginal cost curve MC lies above the average cost curve AC, the latter is rising. It is important to note that we cannot generalise about the direction in which marginal cost is moving from the way average cost is changing, that is, when average cost is falling we cannot say that marginal cost will be falling too. When average cost is falling, what we can say definitely is only that the marginal cost will be below it but the marginal cost itself may be either rising or falling.
