When a firm is embarking upon a project, it needs tools to assist in making the decision of whether to invest in the project or not. In order to demonstrate the use of these four methods, the cash flows presented below will be used.
Net Present Value (NPV)
This method discounts all cash flows (including both inflows and outflows) at the project's cost of capital and then sums those cash flows. The project is accepted if the NPV is positive.
where CFt is the expected cash flow at period t, k is the project's cost of capital, and n is its life.
The NPV represents the amount of present-value cash flows that a project can generate after repaying the invested capital (project cost) and the required rate of return on that capital. An NPV of zero signifies that the project's cash flows are just sufficient to repay the invested capital and to provide the required rate of return on that capital. If a firm takes on a project with a positive NPV, the position of the stockholders is improved.
NPV measures the dollar benefit of the project to shareholders. However, it does not measure the rate of return of the project, and thus cannot provide "safety margin" information. Safety margin refers to how much the project return could fall in percentage terms before the invested capital is at risk.
Assuming the cost of capital for the firm is 10%, calculate each cash flow by dividing the cash flow by (1 + k)t where k is the cost of capital and t is the year number. Calculate the NPV for Project A and B above.
NPV = CF0 + CF1 + CF2 + CF3 + CF4
Project A's NPV = -1,000 + 750/1.101 + 350/1.102 + 150/1.103 + 50/1.104 = -1,000 + 682 + 289 + 113 + 34 = $118 (rounded)
Internal Rate of Return (IRR)
This is the discount rate that forces a project's NPV to equal zero.
Note that this formula is simply the NPV formula solved for the particular discount rate that forces the NPV to equal zero. The IRR on a project is its expected rate of return. The NPV and IRR methods will usually lead to the same accept or reject decisions.
IRR does provide "safety margin" information.
Calculate Project A's and B's IRR.
Project A: -1000 + 750/(1 + IRR)1 + 350/(1+IRR)2 + 150/(1+IRR)3 + 50/(1+IRR)4 = 0
Since it is difficult to determine by hand, the use of a financial calculator is needed to solve for IRR.
The IRR for Project A is 18.32% and for Project B is 15.03%.
This is the expected number of years required to recover the original investment. Payback occurs when the cumulative net cash flow equals 0.
PaybackA = 1 + (1000 - 750)/350 = 1.7 years
Discounted Payback Period
This is similar to the regular payback method except that it discounts cash flows at the project's cost of capital. It considers the time value of money, but it ignores cash flows beyond the payback period.
Again, assume the cost of capital for the firm is 10%:
The payback provides an indication of a project's risk and liquidity because it shows how long the invested capital will be tied up in a project and "at risk." The shorter the payback period, the greater the project's liquidity, the lower the risk, and the better the project. The payback is often used as one indicator of a project's risk.
Average Accounting Rate of Return
This is a very simple rate of return:
Its only advantage is that it is very easy to calculate.
Profitability Index (PI)
This is an index used to evaluate proposals for which net present values have been determined. The profitability index is determined by dividing the present value of each proposal by its initial investment.
The PI indicates the value you are receiving in exchange for one unit of currency invested.
| tobikemper: In the reading it says "The NPV and IRR methods will usually lead to the same accept or reject decisions."|
I think this is wrong, because if one compares investment opportunities of two mutually exclusive projects, it is possible that one project shows a higher NPV while the other shows a higher IRR. (This is even the case in the example that is given in the reading itself!!!) In this case, comparing NPV to IRR would lead to different investment decisions. However, one should invest in that project, that leads to the higher NPV and ignore the IRR.
|piano: tobikemper: the notes is correct. See the textbook Page 23 (the first paragraph): The good news is that the NPV and IRR criteria will usually indicate the same investment decision....|
|kutta2102: Agree with piano. Typically, positive NPV is just a starting point for a project to be even considered. The decision often comes down to: Is the IRR greater than my cost of capital?|
|raymondg: By any chance does anybody know how to calculate the IRR with the Texas BAII Plus|
| yesname: RAYMONDG:|
Follow the following key sequence on TI BA II Plus
CF->2nd->CE!C = Clear all previous values from CF(cashflow table)
Example: Discount rate = 9 Cashflow : CF0=-50 , CF1=100, CF2=50
Keystrokes in CF mode:
50(+/-)- > Enter - > downarrow - > 100 - > Enter - > downarrow - > 50 - > Enter - > Irr- > 9 CPT
|dudu1537: agree but it says usually|
| Lucas24: Dudu, are you by any chance in RSA, your name sounds african, Zulu to be specific.|
Anyway tobikemper is right but so is piano. In 1 project yes NPV & IRR will mostly lead to the same decion, however in mutualy exclusive decision it very possible to get -ve NPV while the IRR is less then COC
|bidisha: in the above example the IRR for project a is greater at 18.32% while the NPV is greater for project B at $148...which one do you choose?|
| gill15: PI seems like a pretty useless index. If you have a comparison to accept or reject for NPV from before the two will coincide always.|
If NPV > 0 accept which would also mean PI > 1..I need to start writing useless index's so I can be published
|farhan92: ^ feel free to name your index after me|
|smurillo: does someone know how to quickly resolve Q 14 of the book´s Practice Problems (page 72)?? can it be done with BA II calculator? Not much explanation given on the solutions...|
