Cash-Flow Calculations
When
NPV
= 0, the solution for
i%
is the periodic internal rate of return.
NFV = NPV x SPFV(i % : N) where N =
TOTAL =
COUNT =
i%
= periodic interest rate.
j
= the group number of the cash flow.
CF
j
= amount of the cash flow for group
j
.
n
j
= number of times the cash flow occurs for group
j
.
k
= the group number of the last group of cash flows.
Nj
=
= total number of cash flows prior to group
j
.
