Accounting Rate Of Return
What's a given business or subdivision or investment worth over its lifetime? See hurdle rate, discounted cash flow, and net present value. Those terms explain the concept better than we can here. The problem with ARR is that it ignores the time value of money - remember that a buck today is worth more than a buck tomorrow. ARR methods of valuing things are also problematic in that they focus on profits - which are definable many ways - rather than cash flows, which are usually much less subject to accounting shenanigans.
