where:
Net present value is dependent on the values of the initial cash flow ( CF

), subsequent
cash flows ( CFj ), frequency of each cash flow ( nj ), and the specified interest rate ( i ).

Internal rate of return is dependent on the values of the initial cash flow ( CF 0) and
subsequent cash flows ( CFj ).
