A break-even analysis is a useful tool for determining at what point your company, or a new product or service, will be profitable. Put another way, it’s a financial calculation used to determine the number of products or services you need to sell to at least cover your costs. When you’ve broken even, you are neither losing money nor making money, but all your costs have been covered.Basically, you need to figure out what your net profit per unit sold is and divide your fixed costs by that number. This will tell you how many units you need to sell before you start earning a profit.
