Problem Data

It is required to find the multiproduct break-even point with the following data:

Fixed Costs (F)


Product 1

Selling Price per Unit (P): 22.5

Variable Cost per Unit (V): 10.5

Sales: 175 units

Product 2

Selling Price per Unit (P): 5

Variable Cost per Unit (V): 1.75

Sales: 175 units

Product 3

Selling Price per Unit (P): 5

Variable Cost per Unit (V): 2

Sales: 100 units

John has been asked to determine whether the $22.50 cost of tickets for the community dinner theaterJohn has been asked to determine whether the $22.50 cost of tickets for the community dinner theater will allow the group to achieve break-even and whether the 175 seating capacity is adequate. The cost for each performance of a 10-performance run is $2,500. The facility rental cost for the entire 10 performances is $10,000. Drinks and parking are extra charges and have their own price and variable costs, as shown below: Tickets with dinner, SELLING PRICE=$22.50, VARIABLE COST=$10.50, ESTIMATED QUANTITY OF SALES UNITS=175. Drinks, SELLING PRICE=$5.00, VARIABLE COST=$1.75, ESTIMATED QUANTITY OF SALES UNITS=175. Parking, SELLING PRICE=$5.00, VARIABLE COST=$2.00, ESTIMATED QUANTITY OF SALES UNITS=100.


The following are the detailed calculations to obtain the multiproduct break-even point according to the data provided. The calculation methods and formulas are based on the book Principles of Operations Management by Jay Heizer and Barry Render:

Break-even Point in Sales Revenue ($)

a) Break-even Point Formula in Sales Revenue ($):

To calculate the break-even point in sales revenue ($), we will use the following formula


  • BEP$: Break-even point in sales revenue ($)
  • F: Fixed Cost
  • Pi: Unit selling price of product i.
  • Vi: Variable unit cost of product i.
  • Wi: Percent each product is of total dollar sales.

Note: The entire expression in the denominator of the formula is known as the weighted contribution.

Likewise, to obtain the value of Wi, we will apply the following expression:

Where Salesi indicates the sales revenue generated by product i.

b) Table to determine the weighted contribution:

Below is a table in which we will apply the formulas indicated:

Product 110.522.50.4670.5331753937.50.7410.395
Product 21.7550.350.651758750.1650.107
Product 3250.40.61005000.0940.056

c) Calculations Explained:

The results shown in the table are explained below:

  • Columns 2 and 3 are data entered to solve the problem.
  • Column 4 is obtained by dividing the values in column 2 and 3.
  • Column 5 is obtained by subtracting the value obtained in column 4 from 1.
  • Column 6 shows the sales data in units that were entered in the problem. Since it is necessary to know the sales in monetary value ($), column 7 is calculated by multiplying column 3 by column 6.
  • In column 8, the contribution to sales of each product was calculated by dividing each value in column 7 by the sum of the sales of all products: $5312.5. It is essential to mention that the sum of all values in column 8 must be 1.
  • Finally, in column 9, multiplying the values of column 5 and column 8. The sum of all the values in column 9 gives us a result of 0.558. This value will be used to replace the formula.

Once we have obtained the value of the denominator of our formula, we will replace its value to calculate the break-even point:

For the company to break-even, it must have revenues of $62724.014

Based on current sales, the company has a loss of $57411.514

d) Sales level by product for the Break-even point:

To calculate the level of sales per product to cover the break-even point, multiply the sales contribution of each product by the calculated break-even point:

ProductsSales level for BEP$
Product 10.741x62724.014 = $46478.494
Product 20.165x62724.014 = $10349.462
Product 30.094x62724.014 = $5896.057

Break-even point in units for each product

To calculate the number of units that must be sold for each product to break even, divide the level of sales per product by its selling price:

ProductsUnits to be sold to cover BEP$
Product 146478.494/22.5 = 2065.711
Product 210349.462/5 = 2069.892
Product 35896.057/5 = 1179.211
