The determination of the break-even point in CVP analysis is easy once variable and fixed costs are determined. A problem arises when the company sells more than one type of product.
Break-even analysis for multiple products is made possible by calculating weighted average contribution margins.
The break-even point in units is equal to total fixed costs divided by the weighted average contribution margin per unit (WACMU).
The break-even point can be computed as: total fixed costs divided by the weighted average contribution margin ratio (WACMR).
For companies that produce more than one product, break-even analysis may be performed for each type of product if fixed costs can be determined separately for each product.
However, fixed costs are normally incurred for all the products hence a need to compute for the composite or multi-product break-even point.
In computing for the multi-product break-even point, the weighted average unit contribution margin and weighted average contribution margin ratio are used.

|BEP||=||Total fixed costs|
|in dollars||Weighted average CM ratio|
Belle Company manufactures and sells three products: Products A, B, and C. The following data has been provided the company.
|Variable cost per unit||60||90||40|
|Contribution margin per unit||40||30||10|
|Contribution margin ratio||40%||25%||20%|
The company sells 5 units of C for every unit of A and 2 units of B for every unit of A. Hence, the sales mix is 1:2:5. The company incurred in $120,000 total fixed costs.
1. Multi-product break-even point in units
|BEP in units =||Total fixed costs|
|Weighted average CM per unit|
|BEP in units =||6,400 units|
a. Computation of weighted average CM per unit:
|∑(CM per unit x Unit sales mix ratio)|
|Product A ($40 x 1/8)||$ 5.00|
|Product B ($30 x 2/8)||7.50|
|Product C ($10 x 5/8)||6.25|
|WA CM per unit||$18.75|
The weighted average CM may also be computed by dividing the total CM by the total number of units.
|WA CM per unit =||(40x1)+(30x2)+(10x5)||= 18.75|
b. Breakdown of the break-even sales in units:
|(B-E point x Unit sales mix ratio)|
|Product A (6,400 units x 1/8)||800 units|
|Product B (6,400 units x 2/8)||1,600|
|Product C (6,400 units x 5/8)||4,000|
The company must produce and sell 800 units of Product A, 1,600 units of Product B, and 4,000 units of Product C in order to break-even.
2. Multi-product break-even point in dollars
|BEP in dollars =||Total fixed costs|
|Weighted average CM ratio|
|BEP in dollars =||$472,000|
a. Computation of weighted average CM ratio:
|∑(CMR x Sales revenue ratio)|
|Product A (40% x 100/590)||6.7797%|
|Product B (25% x 240/590)||10.1695%|
|Product C (20% x 250/590)||8.4745%|
|WA CM per unit||25.4237%|
Take note that this time, the ratio used is individual sales to total sales amount.
|Product A (100x1)||100|
|Product B (120x2)||240|
|Product C (50x5)||250|
The weighted average CM may also be computed by dividing the total CM by the total sales.
|WA CM ratio =||(40x1)+(30x2)+(10x5)|
|WA CM ratio =||25.4237%|
b. Breakdown of the break-even sales revenue:
|(B-E point x Sales revenue ratio)|
|Product A ($472,000 x 100/590)||$ 80,000|
|Product B ($472,000 x 240/590)||192,000|
|Product C ($472,000 x 250/590)||200,000|
The company must generate sales of $80,000 for Product A, $192,000 for product B, and $200,000 for Product C, in order to break-even.
Alternatively, these can be computed by multiplying the individual break-even point in units for each product (computed earlier in #1) by their selling price, i.e. 800 units x $100 for Product A = $80,000; 1,600 units x $120 for Product B = $192,000; and 4,000 units x $50 for Product C = $200,000.
