Understanding Multi-Product Break-Even
Most businesses sell more than one product or service. Each has different prices, costs, and profit margins. Calculating break-even for multiple products requires understanding how your sales mix affects your overall profitability.
The Formula
Break-Even Units = Fixed Costs / Weighted Average Contribution Margin. Weighted Average CM is calculated by multiplying each product's contribution margin by its sales mix percentage, then summing all values.
Example
Coffee shop with $8,000 fixed costs. Coffee: $3.20 margin, 60% mix. Pastries: $2.00 margin, 25% mix. Sandwiches: $4.00 margin, 15% mix. Weighted CM = $3.02. Break-even = 2,649 total items.
Key Takeaways
Use weighted average contribution margin based on sales mix. High-margin products accelerate break-even. You can influence sales mix through pricing and marketing strategies.
