I have run a spreadsheet with all costs (including medical and taxes) and income sources, with what I think are appropriate COL adjustments for each (except for taxes that are based on actual income with current rates, etc) for 35 years and find that due to different timings of different spending & income events, the amount to be w/drawn from investments varies quite a bit from year to year.
Because it is impossible to input all these variables into FIRECalc, would it be an option (just for planning purposes) to take an average of the 35 years worth of withdrawals and use that average as the only withdrawal amount from investments to see how successful plan may be. In the plan, most of the first 20 years would require less than the "average".
Inflation has already been accounted for in adjustments to living expenses and income sources so the "average" withdrawal amount would not be inflation adjusted.
Just trying to find a way to better plan taking into account varying withdrawal amounts.
Am I missing something with this idea?
