I can't imagine ever using SWR as a withdrawal method where all of the risk is piled into the very last withdrawal. I prefer a variable withdrawal method which spreads the risk across all withdrawals. That is, instead of risk of running out of money completely, the risk is now that there might be an occasional withdrawal that is less than what I need to spend. I'd much prefer to scramble on a bad year than to be left with nothing.
Plenty of examples
- taking a fixed percentage of the current value of the portfolio and not adjusted for inflation
- VPW (Variable Percentage Withdrawals) which is described over on Bogleheads and uses amortization to calculate withdrawals
- TPAW (Total Portfolio Allocation and Withdrawals) which is also described over on Bogleheads and has a free online tool. Also uses amortization and creates a customized, dynamically updated glidepath
- Customized versions using amortization and time value of money concepts. A good example is embedded in 2 articles on the bogleheads blog and comes with a link to a spreadsheet.
The last example is the closest to what I'm doing.
Cheers
