Interesting article. Thanks!

One of the assumptions that seems to be in all of the models is using a constant equities/fixed income ratio. Reality says that when the market tanks people are hesitant to move "safe" fixed income dollars into the declining stock market. In minor, short term drops this is probably a mistake. However, in the few "retirement killer" periods keeping cash is probably the best way to prolong the portfolio's life.
1929 starts a big drop. Rebalancing annually moves cash into the market which continues to be slaughtered for several more years. 1970 is another period of collapse where annual rebalancing costs equity dearly and cash disappears from the faithful reallocation.
I'm curious what the real survival numbers are if the rebalancing was only one way. As the market goes up, assets are shifted to keep the fixed income portion from falling too low.
I haven't tried to recreate Dory's numbers but I've made some simple "what ifs" if the market falls but I keep my cash intact. My cash, pension and interest income can pretty much carry me for over a decade. Assuming the stock market doesn't go to zero, I'd be able to rebalance to keep the cash up but it's highly likely that within a decade the equities would recover.
Any thoughts?
While not exactly following what you are suggesting, there was an article in the Journal of Financial Planning in June 2007 - Is Rebalancing a Portfolio During Retirement Necessary.I'm curious what the real survival numbers are if the rebalancing was only one way.

Funny how neither the BusinessWeek article nor any posts on this thread so far mentioned age. But life expectancy is really the primary factor that will determine what a safe withdrawal rate is, assuming the typical definition of "safe" (not broke before death).
other contingency that needs to be considered is the early death of one spouse. In retirement, losing one of the SS payments (and perhaps reducing the amount of a private pension) due to a death would reduce those income streams and could require more to be drawn from the portfolio.
There are a number of what-if scenarios to consider. Identifying those situations and a contingency plan is pretty important.
Here is a page from the Retire Early website where there is a LOT of information on SWR and especially as it relates to age at retirement (years in retirement) and the Safe Withdraw Rate for your asset mix and life exceptancy.
Combining Safe Withdrawal Rates and Life Expectancy
For those of us who are already retired and too lazy to follow the link here is the text.
"With all the worry that the current bear market means they'll run out of cash, most folks have forgotten that there are many things that will actually improve your safe withdrawal rate -- and some of them are easily to calculate with a tremendous degree of accuracy.
For example, there is a large body of data on average life expectancy and how many people will likely live to be 100. If you choose a long pay out period, there is only a small chance you'll actually live long enough to be in a position to run out of money.
The table below is based on a 40-year pay out period and 79% stock, 21% fixed income. The "99% safe" withdrawal rate is 4.10%, "95% safe" rate is 4.23%, and "90% safe" rate is 4.57%.
Using the IRS 2003 Mortality Table we get the following:
A 65-year-old has a 1% chance (99th percentile) of living another 40 years to age 105.
A 60-year-old has a 5% chance (95th percentile) of living another 40 years to age 100.
A 57-year old has a 10% chance (90th percentile) of living another 40 years to age 91.
Combining the probabilities of the portfolio running dry and the odds that our retiree will actually live long enough to see his portfolio run dry yields the following table (see Note (1) below):
Joint Probability
Portfolio Survivability & Life Expectancy
0.20% expense ratio, inflation indexed to CPI-U, January start date, $1,000 initial balance,
Stock allocation in S&P500, remainder of the portfolio in 3-6 month commercial paper
based on Shiller's 1871-2001 database..
----40-Year Pay Out Period-----Odds of Living 40 Years
Beyond Current Age3.90% (99% safe)4.13% (95% safe)4.26% (90% safe)65-year-old (1% odds)99.96%99.76%99.47%60-year-old (5% odds)99.8%99.2%98.6%57-year-old (10% odds)98.3%96.6%95.3%Note (1): The combined probabilities were calculated by examining each of the 92 forty-year pay out periods from 1871-2002 with a January starting date and determining the chance that portfolio would run dry in that year and multiplying that probability by the chance that the retiree would still be alive in the year the portfolio ran dry. The sum of these joint probabilities calculated for each of the 40-year pay out periods examined is the figure reported in the table above. Pretty amazing, huh? A 5% chance that your portfolio runs dry in 40 years, combined with a 5% chance you'll die in less than 40 years, still keeps your overall financial picture solvent more than 99% of the time."
Or, this one on a Bear market and SWR where the starting year for the SWR was 1929...can't get much worse than that for a 30 year retirement period. The SWR for the period was 3.9%. There was still money in the account at the end of the 30 year period.
Retiring at the Worst of Times.
A SWR of around 4% "should" last you at least 30 years unless the market is ever worse than the period after 1929, 1973 or 2002.
Who invented it is less important than the fact that it works for most folks with appropriate adjustments for years in retirement and asset mix. Fees and rebalancing are also very important to keep this SWR near 4%. The data suggests that a SWR of 3.7-4.?% should be adequate for even the worse market years.
Thanks for the post. It always amazes me that people who are smart enough to figure out that they shouldn't do retirement planning with a single interest rate turn around and plan with a single date of death.
The "better" way to handle mortality is by multiplying the probabilities as you've shown.
The intricacies involved in this discussion of the 4% solution are enough to make my head spin - and it's not even CH. I'm still so glad I learned about the 4% solution several years ago. Even if it's flawed, it gives a starting point and is sufficiently conservative to prevent most of us from going broke in early retirement.
In reality, I still don't feel comfortable in following the plan exactly. I plan to limit my WDR to 4% or less each year. I'll not adjust for inflation, but rather start fresh each year and calculate 4%. When I see how that works for a while (NW going up or down) I may reevaluate and increase or decrease spending. During "bad" years, I'll definitely decrease WDR.
The point is, I now have high confidence that I can survive early retirement as long as I stick close to the 4% WDR and stay flexible. It's very liberating! Whoo hooo!
Finally got around to reading this today, thought it was very interesting, thanks for pointing it out...Did anyone take a look at Kitces report?
He suggests that the 4% to 4.5% range (to mark the starting WD amount) is too conservative for some. Especially of the market is down when the WD amount is established.
He suggests that PE ratio might be a good indicator to help people establish the beginning WD Rate to establish the initial WD amount.

Most people use the 4% SWR as the starting position and do not reset it each year. That way the good years can build up a buffer for the bad years, preventing the need to adjust up and down every year.
Make sure to use a liberal assumption for inflation and do not accept government figures on faith.
They are playing with this over at Bogleheads forum. What really really ticks me off - where's the real money?? - aka Psst Wellesley dividends and interest!! rant rant rant .
You're absolutely right Uncle Mick.
What everyone forgets is that earnings (that Psst-thingy you always talk about), plus results from annual rebalancing can result in an initial (or subsequent) drawdown of of less than 4% of the original nest egg.
I'm interested in hearing more about the "Cash management policy". Do you mean the order of withdrawals from different accounts, the way dividends, interest and distribution are used?What's missing from this discussion is the overall cash management policy that each retiree needs to define so they know how to manage their money. The SWR is a part of that policy -- but not the total cash management policy.

Being in my first year of ER, I'm still trying to figure the mechanics of the withdrawls, so all info in appreciated.
I thought that the SWR studies assumed that withdrawals are taken first from dividends, interest and distributions, and if any remains, it is reinvested. What am I missing?
