Alden Co.’s monthly unit sales and total cost data for its operating activities of the past year follow. Management wants to use these data to predict future fixed and variable costs. Predict future total costs when sales volume is (a) 376,000 units and (b) 416,000 units.

Question Completion:

Month      Units Sold        Total Cost

1                  318,000          $155,500      

2                 163,000             99,250          

3                263,000           203,600          

4                203,000             98,000          

5                288,000           199,500          

6                 188,000            110,000        

7                362,000          292,624

8                268,000           149,750

9                  76,400            67,000

10               148,000          128,625

11               92,000            92,000

12               98,000            83,650

Estimate both the variable costs per unit and the total monthly fixed costs using the high-low method. (Do not round intermediate calculations.)

Future total costs when sales volume is:  

                                     (a) 376,000 units   (b) 416,000 units

Variable costs                   $297,040               $328,640

Fixed costs                              6,644                      6,644

Total costs                        $303,684               $335,284

Explanation:

a) Data and Calculations:

Highest: Month 7     362,000     $292,624

Lowest: Month 9       76,400        $67,000

Difference               285,600     $225,624

Variable cost = $0.79 ($225,624/285,600)

Total variable cost:

At Highest Level = $285,980 ($0.79 * 362,000)

Fixed cost = Total costs - Total variable cost

= $6,644 ($292,624 - $285,980)

Check:

At lowest level:

Variable cost = $60,356 ($0.79 * 76,400)

Fixed costs = $6,644 ($67,000 - $60,356)
