@corn18, my approach is to break down my estimated spending budget into decades. For initial decades, I have higher travel costs than later ones, and I have higher long term care costs in later decades than earlier ones, etc.
My spreadsheet then estimates, for each year, all my incomes (investments, SS, small pension etc), these expenses, RMDs, taxes, and determines an ending balance for cash and investment amounts for each year, all adjusted for inflation. I assume making 4.25% on investments, which I guess is an ok conservative average.
All this allows me to play with various scenarios (lie different SS starts) for how to maximize my net worth at 90, my reference age.
I prefer this approach over a 3%, 4%, whatever, withdrawal rate that some people seem to rely on. I don't know or care what my withdrawal rate is. I will just pull out what I need each year, and invest via the buckets approach.
