Future Value/Annuity Calculation

Updated Feb 2021 - User suggestion - add a second person!

Same calculation, just with more variation. A good use of 10 minutes of my time at lunchtime. Enjoy. (P.S. Thank Esther and Anne Marie, not me!)

Another person (Don) was responsible for the new fixed portion field for future desired income, where you can include the portion of your future income that should not be inflated (i.e. covering a fixed expense like a mortgage payment or some other set contract payment of some sort.)
