What is the difference between multi-variety and single-variety breakeven point determination?

Break-even analysis, also known as break-even point analysis or cost-volume-profit analysis, is a mathematical analysis method to predict profits, control costs and judge operating conditions according to the comprehensive analysis of the mutual restriction between product business volume (output or sales volume), cost and profit. Generally speaking, revenue = cost+profit. If the profit is zero, revenue = cost = fixed cost+variable cost, while revenue = sales volume × price, and variable cost = unit variable cost × sales volume. In this way, from sales volume × price = fixed cost+unit variable cost × sales volume, the calculation formula of breakeven point can be deduced as follows:

Breakeven point (sales volume) = fixed cost/contribution difference per unit measurement?

The classification of break-even analysis mainly includes the following methods:

According to the different analysis methods adopted, it can be divided into graphic method and equation method; ?

2. According to the different functional relationships between analysis elements, it can be divided into: linear and nonlinear break-even analysis; ?

3. According to the number of products analyzed, it can be divided into single product and multi-product break-even analysis;
