## What happens when marginal cost equals variable cost?

When marginal cost is greater than average variable or average total cost, AVC or ATC must be increasing. Therefore, the only possible point at which marginal cost equals average variable or average total cost is the minimum point.

## What is the relationship between MC ATC and AVC?

If MC = ATC, then ATC is at its low point. If MC < ATC, then ATC is falling. Relationship Between Marginal and Average Costs Marginal and average total cost reflect a general relationship that also holds for marginal cost and average variable cost. If MC > AVC, then AVC is rising.

**What is average and marginal cost?**

Average and Marginal Cost. Marginal cost is the change in total cost when another unit is produced; average cost is the total cost divided by the number of goods produced.

### How is total cost calculated?

The formula for calculating average total cost is:

- (Total fixed costs + total variable costs) / number of units produced = average total cost.
- (Total fixed costs + total variable costs)
- New cost – old cost = change in cost.
- New quantity – old quantity = change in quantity.

### What happens when AC is equal to MC?

When MC is less than AC, AC falls with increase in the output, i.e. till 3 units of output. 2. When MC is equal to AC, i.e. when MC and AC curves intersect each other at point A, AC is constant and at its minimum point. When MC is more than AC, AC rises with increase in output, i.e. from 5 units of output.

**How does marginal cost differ from variable cost?**

Marginal costs are a function of both fixed and variable costs . Fixed costs of production are considered the costs that occur on a regular basis such as rent or employees’ salaries. By contrast, a variable cost is one that changes based on output and production costs .

#### Is it possible to derive variable cost from marginal cost?

No. You can’t derive variable cost from marginal cost. But you can derive total variable cost from marginal cost under the following situation: Now to derive TC from it we have to integrate over the MC equation.

#### What is the formula to find the average variable cost?

Average Variable Cost refers to the variable cost of per unit of the goods or services where the variable cost is the cost that directly varies with respect to the output and is calculated by dividing the total variable cost during the period by the number of the units. The formula is as per below: Average Variable Cost (AVC)= VC/Q

**What is the difference between average cost and marginal cost?**

The key difference between average cost and marginal cost is that average cost is the total cost divided by the number of goods produced whereas marginal cost is the rise in cost as a result of a marginal (small) change in the production of goods or an additional unit of output.
