Jodi - I have this as a definition - are you cool with it? Return on Investment can and, usually does reflect the rate of return on monetary amounts of gain or, loss which is applied to current and, or, past investments. What this will not help you with is the amount of time involved in an investment. It is the rate or, percentage of gain or, loss in any investment made over the current or previous year. The rate of return is usually adjusted to reflect the adjusted tax base for any given geographical area. These estimations are useful when the averaged periodic returns are all positive, all negative, or, have low variances.
