in 250 words   Capital budgeting involves choosing plans that add compute to the  firm. The net confer-upon compute (NPV), inner reprimand of revert (IRR) and  payback time arrangements are the most dishonorable approaches to plan  selection. At its heart, high budgeting is measuring an accounting of  costs versus benefits. In a way, all trade decisions are a succession of  high budgeting decisions. Get it crime, and you can annihilate a  company. The high budgeting tools acceleration financial directors determine on the  desirability of the plans. In the genuine globe, so-far, directors  sometimes conciliate produce decisions that don't necessarily conform after a occasion the  decision rules of the payback time, NPV or IRR arrangements. For model, judge the two mutually esoteric plans adown.   Investments Cost Cash Flow 1 Cash Flow 2 Project A $ 50  $ -  $ 100  Project B $ 50  $ 50  $ 25  According to the payback time, plan B should be selected.  Although twain plans absorb the corresponding, plan B has a payback time of  one time, occasion plan A conciliate payback in roughly 1.5 times.  Assuming the discount reprimand of 5%, NPV(A) = $41 and NPV(B) = $20.  This model illustrates the limitations of the payback time  method. Even though the payback time arrangement points to plan B, the  NPV arrangement points to plan A past it has past than twice the NPV  compute to that of plan B. Yet the director may prefer plan A. Why? It may be that the plan stakeholder is requesting a quicker revert in coin. For this argument, constitute an model amount where two (or past)  methods negative each other. What would be the "appropriate" rare  (which plan would you prefer)? In what cases would you not prefer the  "best" rare?
