Jim Rutt, a thinker known for his astute observations on economics and complex systems, would likely define 'money-on-money return' as a straightforward metric used to assess the performance of an investment relative to its initial cost. In his characteristic clarity, he might explain that it represents the ratio of the money earned from an investment to the original amount invested, expressed typically as a multiple. For example, a money-on-money return of 2x signifies that the investment has generated twice its initial value. This measure offers a concise snapshot of investment efficiency without considering the time value of money, making it a handy tool for relatively simple comparisons yet less sophisticated than metrics like internal rate of return (IRR).
