If one retired in 1965 and began to withdraw the same percentage from the PP each year through to the current year, what is the maximum fixed percentage that could be withdrawn annually and still allow the initial portfolio to still be the same in inflation-adjusted dollars as it was on the day of retirement?MachineGhost wrote: Do you mean the inflation-adjusted value each year of the initial starting balance as the lower threshold for each year's total portfolio value?
For example, Tyler's Withdrawal Rates calculator (https://portfoliocharts.files.wordpress ... -rates.jpg) shows that the PP has a sustainable withdrawal rate of ~4.2% since 1972.
