Fixed Cost Behavior

Total Fixed Cost Remains constant Remains Constant
Fixed Cost Per Unit Decreases Increases
Consider the followingconcert example where theband will be paid $48,000
regardless of the number of tickets sold.

Fixed Cost Behavior
Tickets sold 2,700 3,000 3,300
Total cost of band 48,000$ 48,000$ 48,000$
Per ticket cost of band 17.78$ 16.00$ 14.55$
$48,000 ÷ 3,000 Tickets = $16.00 per Ticket

2-5
Variable Cost Behavior
Total variable cost increases in
direct proportion to the number of
units sold.
The behavior of variable cost per
unit is contradictory to the word variable,
because variable cost per unit remains constant regardless of how many units
are sold.

When activity . . .
Consider the concert example where a band receives $16 for each ticket sold. The more sold
will increase the band’s take from the concert, but they can only receive a constant $16 from each individual ticket sold.

Demonstrate the effects of
operating leverage on profitability.

Tickets sold 2,700 3,000 3,300
Band cost per ticket sold 16$ 16$ 16$
Total cost of band 43,200$ 48,000$ 52,800$
The total variable cost increases in direct proportion to the number of tickets sold.
Variable unit cost per ticket remains at$16 regardless of the number of tickets sold.
Variable Cost Behavior

Mixed, or Semivariable, Costs
Mixed costs (or semivariable costs) include both fixed and variable components.
For example, Star Productions, Inc., has to pay a janitorial company a base fee of $1,000 plus
$20 per hour required to do each cleanup job. The $1,000 base fee is fixed. The $20 per hour is variable. If 60 hours are required to accomplish a
cleanup, the total mixed cost is:
$1,000 + ($20 x 60 hours) = $2,200

Operating Leverage A measure of the extent to which fixedcosts are being used in an organization.
Operating leverage is greatest in companies that have a high proportion
of fixed costs in relation to variable costs.
A measure of the extent to which fixedcosts are being used in an organization.
Operating leverage is greatest in companies that have a high proportion
of fixed costs in relation to variable costs.
Consider the followingconcert example where
all costs are fixed.

Risk and Reward Assessment
Risk refers to the possibility thatsacrifices may exceed benefits.
Risk may be reduced byconverting fixed costs
into variable costs.
Let’s see what happens to the concert example if the band receives $16 perticket sold instead of a fixed $48,000.
![Page 13: Acct 2220 - Chp 2: (Review in conjunction with Chapter 2 reading) Copyright © 2014 McGraw-Hill Education. All rights reserved. No reproduction or distribution.](https://reader038.fdocuments.in/reader038/viewer/2022110322/56649d0d5503460f949e1970/html5/thumbnails/13.jpg)

Shifting the cost structure from fixed to variable not only reduces
risk but also the potential for profits.

Recall the earlier concert example, where the band was
paid $48,000 regardless of the number of tickets sold.The cost of the band is fixed relative to the number of tickets sold for a specific concert.
The cost of the band is variable relativeto the number of concerts produced.

Unit variable cost = $4,000 ÷ 5,000 units = $.80 per unit Fixed cost = Total cost – Total variable cost
Fixed cost = $9,700 – ($.80 per unit × 10,000 units) Fixed cost = $9,700 – $8,000 = $1,700
Total cost = Fixed cost + Variable cost Total cost = $1,700 + $0.80X

Total variable cost = Total cost – Total fixed costTotal variable cost = $16,000 – $10,000 = $6,000Unit variable cost = $6,000 ÷ 3,000 units = $2
The Scattergraph Method
Estimated fixed
is $10,000
The horizontal line shows that the total cost of
3,000 units is approximately $16,000.

Regression Method of Cost Estimation
A method used to analyze mixed costs if a scattergraph plot reveals an approximately linear
relationship between the X and Y variables.
This method uses ALL of thedata points to estimatethe fixed and variablecost components of a
mixed cost.

Regression Method of Cost Estimation
Software can be used to fit a regression line through the data points.
The cost analysis objective is the same:
Y = a + bX
Least-squares regression also provides a statistic,
called the R2, that is a measure of the goodness
of fit of the regression line to the data points.
