The Vanguard Dynamic Spending Rule: A Closer Look at Its Pros and Cons

The Vanguard Dynamic Spending Rule is one of several retirement withdrawal strategies that use the guardrails concept. The idea, in theory, is to generate a spending plan that has some of the annual spending consistency of the 4% Rule, while at the same time remaining sensitive to market fluctuations.
In this video I'll walk through how the rule works, its pros and cons, and a free tool that will enable you to test the Vanguard Dynamic Spending Rule for yourself.

    This is a great analysis, I've watched a number of other videos on this subject and this is the clearest by far. It's really important to see how much spending can actually drop by. As in many cases that are "successful" in not running out of money they're not really successful as a retirement plan as the spending is cut by so much. Thanks for the thorough explanation

    Concur with the numerous comments Rob - excellent video especially for many of your viewers (myself included) that utilize Vanguard. I had Vanguard imput a specific amount of $$ for end of plan. As you noted - dynamic spending plan is successful if you have any money left. I believve one of the best withdrawl strategies is one you covered in a previous video - RMD withdrawl rates. I am 70 and the plan is to pursue that strategy when I turn 72. Retired at 60 and have averaged 2.5% however I am fortunate that I have a pension and SS that afforded me to be very conservative. Rob - Keep doing what you are doing. I also find hyour weekly news letter has some great nuggets of info !

    Your average return has been 2.5%? That's Abysmal!!!! That's Not even keeping pace with Inflation! And if you're fortunate to have a Pension then THAT is your conservative portion of your "portfolio" so to speak! While I'm not saying you need to be 100% in Equities, I am saying, You need someone a lot smarter than you to advise you on where to put your Nestegg!! At the very least, seek out a fee only Investment Advisor! You really don't understand what is going on. The 10 Year Return of the S&P 500 was at 178.6% This is higher than the long term average of 115.0%. Ie: You left A LOT of money on the floor over this past decade!

    So helpful as always, Professor Berger. After looking at all these different strategies, it seems like the best one is (1) starting with a conservative withdrawal rate (like 3%) if you can afford to and (2) using some common sense, informed by a good retirement planner like New Retirement, to see if you need to pare back spending. These strategies also need to account for the gap years between retirement and Social Security (62 to 70). Mike Piper has an interesting plan for that, involving setting aside money from the rest of your portfolio. And then there is the idea of setting aside some money from your portfolio to anticipate long-term care needs. Good luck, average retiree!

    I think the Vanguard Dynamic Spending rule is the best you going to get especially if you value making the most of all your money (not leaving it behind when you leave the planet). I think the analysis at the end is a little deceptive. Look at the difference between the median spend of the VDS and the percent of portfolio median. Or look at the average spend between '75 and '85. The VDS recognises that the percentage of portfolio rule is the way to go, but you don't have to panic if the market drops, you can work you way down.

    Excellent session! None of these formulas are hard core rules, but this suits a LOT of things I have been noodling over (in my head) and starts applying benchmarks I think mixing this up with Retirment Manifesto’s idea of adjusting the ceiling and floor, based on just how big the market fluctuates each year, would get even closer… I guess I’m making it even more convoluted. I’m all in on doing the homework each year .. I speak excel. Once you reach RMD age, you have tokeep track of these things, anyway. Speaking of floors, your 2.5% might not meet the RMD requirements … I would make the floor the RMD minimum requirement. If you are not yet RMD age, make sure your floor is less than the RMD requirement.

  • @soundslight7754

    Rob, you say 4% is a "fixed $ amount strategy" - spending same $ amount each year, but I wonder if it is so. I mean how can it be fixed $ amount if it's spending 4% of the capital that goes up and down all the time!? Even if the capital is fixed and doesn't change from year to year, the fact that we withdraw 4% of it every year, means the capital is reduced next year so either the spending next year has to be lower to stick to 4%, or we spend a bigger percentage to keep the $ amount the same. I see it this way: we spend 4% of the capital sum each year whatever it is and the $ amount of spending could drops a bit some years or be a bit more than last year, this works fine over long term if capital grows by at least 4%, what do you think?

    The Vanguard DSR is way too complicated for what it does. When I comparison tested it to an old school 4% of your portfolio rule, it didn't produce dramatically different results, so why bother with all the crazy guard rail stuff? Seemed to me like it was a rule designed to shift people away from self directed accounts to managed accounts to generate an extra 0.30% in fees. If Vanguard thinks it's such a great rule they ought to give away a calculator on their website (or at least have a link to FICalc)

    I think as a modeling strategy this is good. In general if the stock market is down you are probably going to be looking at your budget to cut corners, and when the market is high you are going to be more carefree in your spending. One aspect that bothers me about all of these analysis is that it assumes that inflation is increasing at a continuous rate when in fact it should be treated statistically just like the other parameters. Over time your property taxes might be tracking inflation, but most years it may not change much. Same for other factors, costs can go up and down while they are statistically likely to increase. This can be important because if we have a few years of high inflation that are correlated with bad market performance then that is where we really need to tighten our belts, but if inflation and the markets are increasing together, then the risks are obviously reduced. In the end we need to stress test our plan, but as we execute our plan we need to continuously reevaluate our situation. What was *my* inflation this year. If it wasn't so much, no need to withdraw more just because it was part of the model we used to estimate our risks.

    Another wrinkle for me, and probably many of your viewers, is RMDs. I’m still working at 70 but will probably quit when RMDs kick in at 73. All employer retirement accounts will be consolidated into my three index fund rollover IRA where the withdrawal rate will be out of my control. RMD + social security will probably exceed my spending needs in most years so I need a plan to efficiently manage the excess.

    hmm, i wonder if the inputs were in correct. your withdrawal rate is set at 5%, and never decreases by more than 2.5% of previous year withdrawal, and never increases by more than 5% of previous year withdrawal. That doesn't seem to actually replicate VDSR, since 5% increase of 5% is higher than the 5% ceiling, and 2.5% decrease from floor, would be lower than the 2.5% floor, since the variable is of previous year withdrawal. So, seems like you are ever expanding the actual 2.5%-5% range, or am I just confused on the wording. VDSR you would not exceed 5% ceiling or 2.5% floor.
