COST-VOLUME-PROFIT RELATIONSHIPS 23 Cost behavior CVP Analysis Break-even analysis
Cost Behavior Costs that vary in direct proportion to the level of activity. Total cost - increases with activity Per-unit cost -remains nearly constant = $1.21 / ticket y = 1.21x R 2 = 0.98 Variable Cost
y = 1604 R 2 = 0.00 Total cost –remains nearly constant = $1604 / month Per-unit cost - decreases with increase in activity (Note: Per-unit fixed cost can be misleading.) Fixed Cost Costs that are unrelated to the level of activity.
y = 0.59x + 3,625 R 2 = 0.92 Variable or Fixed Cost? Some expenses have both fixed and variable components.
An algebraic expression representing a cost as a function of fixed and variable components. Y=F+VX Y=total cost F=fixed component V=variable cost per unit X=number of units Vehicle Maintenance=$3,625+$0.59 X Cost Functions
( 17,700, $13,100 ) ( 3,300, $5,620 ) High-Low Method
( 17,700, $13,100 ) ( 3,300, $5,620 ) $7,480 14,400 (1) Find the variable cost (slope). Variable cost: $7,480 14,400 = $0.52/unit
( 17,700, $13,100 ) ( 3,300, $5,620 ) Slope = $0.52 (2) Find the fixed cost (y-intercept). ~ $4,000 Fixed cost: $13,100 - $0.52 x 17,700 = $3,896 ( 17,700,$13,100 )
y = 0.59x + 3,625 R 2 = 0.92 A more precise way to estimate cost functions. Use trendline function in Excel. Takes all points into account. Least-Squares Regression
Don’t use a trendline to estimate. $8,450 $4,100 Some expenses are fixed within a certain range. Relevant Range
Costs cannot be negative! Consider this a fixed cost equal to the average amount. Plausible Cost Functions
