Enter cash flow at time (t)

  

Enter Discount Rate % (i)

  
      

Calculate the Net Present Value using:
Cash Flows you entered
Internal Rate of Return (IRR) of 8%

NPV formula:

PI  =  NPV without Initial Investment
  Initial Investment

NPV = ΣPVt
where PVt is denoted as
PVt  =  Ct
  (1 + i)t

where Ct = cash flow at time t
and i is the discount rate

Calculate the discount factor

(1 + i) = (1 + 0.08)
(1 + i) = 1.08

Now calculate each PV

Discount back to time 0

TimeCt)(1 + i)tPVt = Ct/(1 + i)t
0-8,000.001.00000-8,000.00
15,000.001.080004,629.63
25,000.001.166404,286.69

Determine NPV

NPV = ΣPVt
NPV = -8,000.00 + 4,629.63 + 4,286.69
NPV = 916.32

Since NPV is more than 0
We should pursue the project.
