1. Sunday, July 17, 2011 - 7:51 PMDuh, well, yes. With the dumbing-down of the WSJ under Murdoch, I suppose we should get accustomed to trivial pieces like this, but it does insult one's intelligence. The most important factor in retirement planning is the SWR, or safe withdrawal rate. I assume this is too complicated for the Murdoch-era WSJ folks. Luckily, it is not too complicated for others. I defer to the folks at Bogleheads, but it goes something like this:
(a) Calculate how much you will need in retirement to cover at least the basics;
(b) Add how much you will need to cover "nice stuff" you'd like in retirement;
(c) Immediately disregard (b);
(d) Add up all the assets you can sell, pawn, or tap, disregarding your owner-occupied real estate;
(e) Multiply (d) times .04 (4%);
(f) Add to (e) any pensions, social security, annuities, or other sources of income in retirement;
(g) Multiply (e) plus (f) times [1 minus your effective rate of taxation (state and federal)];
(h) If (g) is greater than (a), good. If (g) is greater than (a) plus (b), that's really good.
Welcome to planning for retirement 2.0.

2. Sunday, July 17, 2011 - 9:34 PMBozo, that's the best primer I've seen for determining the amount of assets needed to retire. My only quibble is that it assumes a person can achieve a 4% return on their money.

My interpretation of Bozo's formula isn't that it assumes a 4% return (on investment). The withdrawal rate is established at 4% (initial value), implying a 25 year payout with any ROI in excess of inflation extending the duration.

Re: My over-simplified retirement calculator
SWR purists over at Bogleheads might disagree with my calculator. The Trinity Study, for example, assumes various asset allocations tilted toward equities and factors in a yearly increase in the SWR. It all gets very complicated (overly-so if you ask me). I "tilt" to a kinder, gentler, calculation, which can be modified yearly, based on actual ROI. For example, a SWR predicated on an asset allocation of 75% equities/25 % cash/bonds is unrealistic for most retirees (too much risk). And most of the SWR studies I have reviewed are quite vague on the assumed rate-of-return on the "bond/cash" component of the allocation. So, I came up with my own "calculator", which (as Craig suggests) is designed to last longer than 25 years if you "out-perform" or permit a modest inflation-adjusted yearly increase, or a combination of both. Conversely, if your portfolio takes a hosing, you merely apply the age-appropriate SWR percentage to whatever you have at your yearly re-calculation, and tighten your belt accordingly. You can (and should) adjust your SWR percentage as you get older. A person 70 years old might wish to use a SWR of 5%, which (at least theoretically) should provide income to 90 (the same as a person 65 using 4%). A person 75 years old might wish to use 6.67%, and so on. Bottom-line is to give yourself income to 90, and cover anything beyond that with longevity insurance (essentially, a delayed single-payment annuity).
Retirement planning is not as complicated as many would have us believe. You can really do your planning quite adequately with a note pad, a calculator, and a couple of cups of coffee (or a couple of beers, if you're so inclined).

5. Monday, July 18, 2011 - 6:17 PMI guess I am old fashioned. I like to know that I can live comfortably from the interest income from my portfolio without ever having to spend the principal down. This might be overly cautious, but it has worked for me. So I mistakenly assumed you meant a 4% return on your money.
