Pretend you are the CFO of a manufacturing company with ten product lines. The president of your company has asked you to write a memo to him to explain CVP analysis and how he can use it as a tool for planning and controlling costs. Additionally, he would like to know how he can use this information to decide if he should drop one of his product lines and instead focus on the remaining nine product lines. He understands accounting, but needs a refresher on the different types of costs and how they affect the break even point of a product and ultimately profit.
