This is illustrated by one of the examples. I have attempted to insure that the calculations performed here are correct, however this calculator is provided without guarantee. All of the parameters after amt in these functions have default values, and you may leave off those on the right side whose default values are what you want. The label at the end of a cash flow function is optional. The first one will be after sy periods, and they will then occur every fy periods after that.
All cash flows occur at the beginning of a period.
This amount will increase at the rate of tr and be discounted at the rate of dr each period. Note that the value is for period 0 even if the first cash flow is adjusted forward by sy periods. The default value of this parameter is 0.0. Defaults to 0.0. The number of periods to shift the first cash flow out.
