RELATIONSHIP BETWEEN
AVERAGE VARIABLE COST AND MARGINAL COST
Marginal cost: Cost of producing one extra unit of output.
Average variable cost: The per unit variable cost of
production.
Relationship:
- Till the point where marginal cost is below the average
variable cost, the average variable cost will decrease.
- From the point where marginal cost becomes more than the
average variable cost , the average variable cost starts
rising.
- The marginal cost curve always cuts the average variable cost
from the lowest point of the average variable cost curve.
The above mentioned points can be observed in the graph given
below:

RELATIONSHIP BETWEEN
MARGINAL COST AND AVERAGE TOTAL COST
Average total cost: The per unit cost of production.
Relationship:
- Till the point where marginal cost is below the average total
cost, the average total cost will decrease.
- From the point where marginal cost becomes more than the
average total cost , the average total cost starts rising.
- The marginal cost curve always cuts the average total cost from
the lowest point of the average total cost curve.
