PV & FV of Periodic Uneven Cash Flows & Rates

I am just fooling around with cash flows at this point. My last post was “PV & FV of Periodic Uneven Cash Flows, where I showed an easy way to enter cash flows that changed for different periods of time. I thought it might save time over entering all the cash flows separately. I am not going into details about this spreadsheet (UnevenPlusRate). Go back to “PV & FV of Periodic Uneven Cash Flows” for more information about calculations. Let me know if you see any errors, as I am making these cash flow calculation up as I go along and not testing them.

In this post I have taken it one step further and added a change in rate each time the amount and term changes. I am not sure what it can be used for in real life problems, maybe discounting an annuity that changes payouts, by the forward yield curve?


I have also added a cash flow that takes the data entered in the yellow input cells and populates an actual individual cash flow and calculates the present and future values, as a proof of the original calculations:
