3. Summary of cost behavior:
Costs Fixed Costs Variable Costs
Total Costs Constant, regardless of
levels of production and
sales.
Changes, in direct
proportion to the change
in the level of production
and sales.
Unit Costs Changes, decreases as
production increases and
vice versa.
Constant, regardless of
levels of production and
sales.
How to control? Increase production to
reduce unit fixed costs,
that is why, fixed cost is
related to volume.
Reduce unit variable cost
to reduce total variable
costs, that is why, variable
cost is related to spending.

4. Mixed Costs
• Costs which could not be perfectly classified
as pure fixed costs or pure variable costs.
• Have a characteristics of both the fixed and
variable costs.

6. Semi –variable
cost
Changes in total
but not in direct
proportion to
changes in the
level of production
and sales.

7. Semi-fixed costs
Constant in a given
level of activity but
changes , not in a
constant way,
when a new level
of activity is
reached.

8. Step costs
Constant in a given
level of activity and
changes, also in a
constant way as
new level of
activity is reached.
