Cash Flow Example

After an initial investment of 80,000.00, cash flow (0), you expect returns over the next five years as follows:

Cash Flow	Cash Flow Amount	Occurrences
Number
1	5,000.00	1
2	4,500.00	1
3	0.00	1
4	4,000.00	1
5	5,000.00	5
6	115,000.00	1

Given this information, calculate the total of the cash flows and the internal rate of return (IRR) of the investment. Calculate net present value (NPV) and net future value (NFV), assuming an annual investment interest rate of 10.5%. See Figure 1 for the cash flow diagram and Table 4-2 for how to enter the cash flows. The example is shown with RPN as the active operating mode.
