The Choice between NPV and IRR in Investment Decisions
What is the NPV criterion decision rule? Why is NPV considered to be a superior method of evaluating the cash flows from a project?
Risk Transmission Relationship between NPV and IRR in Economic Evaluation of Project Management;
Assume that a firm is faced with the prospect of choosing between two mutually exclusive investments whose cash flows; timing, NPV, and IRR are given as following. (A required rate of 8% is assumed for NPV computation.)
When we use NPV to rank investments, the ranking of investments can depend on the interest rate.
The internal rate of return (IRR for short) of a project is simply the interest rate that makes the NPV of the project equal to 0.
NPV method assumes that each cash inflow received is reinvested at the required rate of return, whereas the IRR method assumes that each cash inflow received is reinvested at the computed IRR.
如果這個NPV是正的，那麼這個項目可能就值得繼續進行，除非它不能比投資其它項目有更高的價值。

NPV是一種用於資本預算的方法，在預算中要從現金流入的現值中減去現金流出的現值。
The method can be used directly for simultaneous optimization of the main parameters of open-pit mining such as final mine perimeter, long-term mining schedule( or mining sequence), production capacity and mining life with the maximum NPV( Net Present Value) as its object.

NPV (Net Present Value)
Thus, if NPV is greater than zero, the project is profitable and therefore is acceptable.

NPV breakeven analysis examines a value of each factor which makes NPV exactly zero.
Optimization for NPV on the Decision in Production Renewal and Change;
The IRR can be found by trial and error by using a number of discount factors until the NPV equals zero.
By adding the value of options to the NPV formula, we extend the traditional NPV rules.
Relatively small error in estimating individual cash flow with steeper slope leads to a large error in estimating project's NPV.
Net Present Value (NPV)
If the cash inflows of each year are same, the computation of NPV can be simplified by using the table of present value of annuity.
Using the table of present values, the calculation of NPV is as following...
Analysis of Real Estate Project Investment Based on Extended NPV;
If the NPV is negative the project should be rejected because it is not a wealth creating opportunity.
實體經濟的世界中，企業的價值是依據未來期待收益所換算出來的淨現值/NPV，但是，處於看不見的新大陸中的企業，則是根據將來市場佔有率的期望值，來決定企業價值的多寡。因此，才可以做到動用自己資本的幾十倍甚至幾百倍的鉅額資金，去吞併比自己更強大的企業。
An NPV calculation estimates the value of a venture over its lifetime, taking into account(1) investments required to launch and maintain the venture;(2) cash flows that the venture generates; and(3) the cost of financing the venture as reflected in a discount rate.
