13) Calculate the present value of a perpetuity with a $6.50 payment per year and a 6.5% annual interest rate.
To calculate the present value of a perpetuity, you just divide the payment by the interest rate. Therefore, the present value would be:

How much would you be willing to pay for this investment if your required rate of return is 12% per year?
Use Excel’s =NPV(B1,B5:B9) function. Note that we did not include the period 0’s cash flow in the function. Excel’s NPV function doesn't really calculate net present value. Instead, it simply calculates the present value of uneven cash flows. It does not take the cost of the initial outlay into account.

There is no function to calculate the future value of uneven cash flows. Therefore, we need to find the future value of each of the cash flows individually and then add them all together.
The cash flow in period 1 needs to be taken four periods forward (moved from period 1 to 5) so the formula in C5 is: =FV($B$1,$A$9-A5,0,B5). Notice that NPer is calculated by taking the period of the last cash flow (5, in A9) minus the period of the current cash flow (1, in A5). Also, note that the dollar signs serve to freeze the reference so that when you copy the formula down those addresses won't change (i.e., they are absolute references). Copy and then paste that formula into A6:A9. To find the future value of the cash flows in B11, use the formula: =SUM(C5:C9).

Another way to find the future value of any set of cash flows is to first find the present value of those cash flows and then to find the future value of that present value. The picture, below, demonstrates the process:
We already saw that we can calculate the present value of uneven cash flows using the NPV function, so we will use the NPV function for the PV argument in the FV function. The formula becomes: =FV(B1,A9,0,NPV(B1,B5:B9)).
