Businesses can use break-even analysis to help persuade sources of finance to give them money
Break-even analysis influences decisions on whether new products are launched or not
Disadvantages of break-even analysis
Break-even analysis assumes that variable costs always rise steadily, which isn't always the case
Break-even analysis is simple for a single product, but most businesses sell lots of different products, so looking at the business as a whole can get a lot more complicated
If the data is inaccurate, then the results will be wrong
Con-Break-even analysis assumes the business sells all the products, without any wastage, but in reality there may be some wastage (e.g. in a restaurant business)
Con-Break-even analysis only tells you how many units you need to sell to break even, it doesn't tell you how many you're actually going to sell
