PV and FV

 Can anyone please explain Present Value and Future formula.Here is an example comparison of two projects using this technique:

Here is an example comparison of two projects using this technique:

Project A is expected to make $100,000 in two years.

Project B is expected to make $120,000 in three years.

If the cost of capital is 12 percent, which project should you choose?

Using the PV formula used previously, calculate each project’s worth:

crushPMP's picture

Project 1


PV = FV/ (1 + r)^n


PV = 100/ (1 + 0.12)^2


PV = 79719.387755


Project 2


PV = FV/ (1 + r)^n


PV = 120/ (1 + 0.12)^3


PV = 85413.629737


 


Project 2 wins

 This helps.

one last question, if I get Cost management answers wrong, Can I still pass pmp exam? I know I can get a few right. but I am really challenged in this area. I am scheduled to appear for exam on 22nd May. I have been doing fairly well in other areas, at 70%.

Should I take the exam or reschedule it.? I want to pass it in first attempt. Please advise.

I think method of calcualtion should be as below:


Project A:


PV={100000/(1+0.12)^1 }+ {100000/(1+0.12)^2}


Project B:


PV={120000/(1+.12)^1} +{120000/(1+0.12)^2 }+ {120000/(1+0.12)^3}


 


The answer would be correct, as Project B. Please correct me If I'm wrong.
