SUMMARY

You may use the Present Value function (PV) to calculate the Net Present Value (NPV) of an investment that has a series of per =NPV(.13/12,1470,1470,....,199633.33)

The PV function simplifies this calculation if set up as follows:


   A7:  13%            B7:  =A7/12
   A8:                 B8:
   A9:  -1470          B9:  6
   A10: -1633.33       B10: 95
   A11: -199633.33     B11: 1
   A12: =PV(B7,B9,A9)+PV(B7,SUM(B9:B10),A10)+PV(B7,SUM(B9:B11),A11)
        -PV(B7,B9,A10)-PV(B7,SUM(B9:B10),A11)

The NPV for this series of cash flows calculates to -165,561.70.

The solution process:

PV(13%/12,6,-1470) finds the PV of the first six periodic cash flows.

PV(13%/12,6+95,-1633.33) finds the PV of the next 95 periodic cash flows as if they were received from the beginning of the investment.

PV(13%/12,6+95+1,-199633.33) finds the PV of the last periodic cash flow as if it was received from the beginning of the investment.

PV(13%/12,6,-1633.33) and PV(13%/12,6+95,-199633.33) subtract the PV of the periodic cash flows that were not received.
