Capital Costs - One Reason Why The Corporate World Doesn’t Think Long Term
Tuesday, April 1st, 2008
As I was reading through Suburban Nation, an excellent book on Urban Planning , I stumbled on a very well written footnote which quickly and simply explains how the cost of capital affects long term thinking in corporations. I’m going to quote liberally, because, as I said, I feel they nailed it pretty well, and admittedly my business knowledge is pretty limited.
Cost of capital, narrowly defined, is the interest rate at which money is borrowed, but it could be more accurately described as the income that could be earned on a given amount of money were it invested elsewhere. For most successful companies, this cost of capital is well over 10 percent, and in the high-risk field of real estate, it is often 20 percent. When contemplating an investment, businesses create cost-and-income spreadsheets in which all future earnings are discounted at this rate. A dollar earned next year is worth about ninety cents this year, since it could have been invested elsewhere at 10 percent.
With this logic, the cost of dollars made or saved in the future begins to sharply decline. In ten years a dollar is worth only thirty-five cents, and in twenty it’s worth only twelve. Start to go much further beyond that and it gets virtually worthless.
When looking at an environmentally sustainable investment like geothermal heating or solar panels, which need large up-front costs but can provide an overall savings when calculated over the long term, it becomes clear how cost of capital could make an otherwise sensible long-term project much less viable.
