Cash Flow
where:
Net present value is dependent on the values of the initial cash flow (
CF
0
), subsequent
cash flows (
CFj), frequency of each cash flow (nj), and the specified interest rate (i).
irr() = 100 × i, where i satisfies npv() = 0
Internal rate of return is dependent on the values of the initial cash flow (
CF
0
) and
subsequent cash flows (
CFj).
i = I% ÷ 100
