A manager or executive in charge of a profit center is likely to face a much more difficult job than someone overseeing a division that is not classified as a profit center. The reason is simple. A profit center manager is going to have to both increase sales by generating additional revenue and decreasing costs (as a percentage of revenue), much like an entrepreneur would have to do in his or her own independent business.
A cost center manager, on the other hand, only has to worry about staying within budget. (A cost center is a department that is important to the overall success of a company but its contribution to revenues and profits can be only incrementally measured. A cost center is an area that typically runs red ink in upfront losses but will result in a much richer company if managed correctly; think the research division of a major pharmaceutical corporation that spends billions developing new drug treatments without selling a single pill for years. Clearly, if the pipeline were to dry up and the cost center shut down, the company would soon find itself a shadow of its former self. Yet, it is a cost center and not a profit center that is likely to find itself at the top of a list when it comes to recessionary layoffs.)
Many businesses are tempted to treat all divisions as cost centers instead of profit centers. This can be a horrible mistake because if managers are rewarded simply on cutting costs, they will not make sufficient reinvestment in a business to grow profitably for the future. Hence, you eventually end up with outdated equipment, facilities, and staff and your customers are likely to go elsewhere because their needs aren’t being met. A profit center approach, on the other hand, blends the need for current cash with the desire to grow earnings in the future, making a manager accountable for the long-term health of a business.
A closely related concept to a profit center is an investment center. Whereas a profit center measures simply the overall contribution of a division’s profitability to the parent corporation, an investment center measures all uses of capital against a theoretical required rate of return. Although the investment center approach is extremely useful in evaluating the overall profitability of a company as measured by return on capital deployed, it can be manipulated by managers who know how accounting rules work. By simply modifying depreciation rates, for instance, they could increase the estimated return on invested capital. They could also change the so-called hurdle rate to a more easily attainable figure (the hurdle rate is a return a profit center or other division must earn in order to be considered a good investment for the company; in other words, it is a minimum acceptable rate of return).
The legendary management consultant and thinker Peter Drucker originally created the term profit center in the 1940’s. He subsequently asserted that the term profit center is a misnomer that leads managers to focus on the wrong overall priorities, insisting instead that everything is a cost center. By focusing only on the absolute profit of a division, factors such as return on capital, opportunity cost, efficient use of resources, and relative returns are ignored to the detriment of the stockholder or owner.
