As a performance measure for comparing company performance, it is useful to know how much profit is generated for each $100 of capital invested in the balance sheet.
Example: There are two businesses producing similar products and services. They both make the same profit, $1m per annum. Business A has $3m invested in the balance sheet (in working capital, fixed and other assets). Business B has $2m invested in the balance sheet. Which is the better business?
For each $100 invested in the balance sheet, Business A produces $33 profit. Business B produces $50 profit.
If one were comparing this performance measure, then Business B is the better performer.
On the other hand, if the purchase price for Business A were cheaper, then A could be a good investment, as the new owners will know that they can get the balance sheet in order to improve the financial outcome.
All companies and businesses should be on top of their financials. There are software tools like Strategic Focus to help with performance measures e.g. NOPAT, business performance and detailed financial analysis and to suggest areas that need to be improved.
