What Is Profitability Analysis?
To run a successful business, you need to know where your profits are generated. It's possible to group outputs by product, customer, location, channel, or transaction. The first step is to allocate costs through a process known as costing. Once you know the cost per output unit, you can deduct it from its revenue, and you'll get the profit margin of a product, customer, location, channel, or transaction.
On its own, this information doesn't say much other than whether you're on the positive side of revenues or it is costing you more to produce a product than what you're gaining. However, managers can use this analysis to compare products, locations, and customers and decide to shut down the least profitable ones. Pruning the portfolio this way is necessary in times of crisis and recession, but it should be an ongoing activity.
