I’m confused about the 4% (or any %) withdrawal strategy. Do I have it wrong?

AUTHOR: R Quinn on 9/25/2025

I realize we touched this topic before, but I just watched a YouTube video where the “expert” debunked the 4% rule. His criticism was simply that is not how people spend money. He said nobody lives on the percent they withdraw giving the example that if a person had $1,000,000 and took $40,000 they may need more money for unexpected spending. Thus they will take extra from the $1,000,000 

That’s like saying nobody can live on a pension or salary for that matter because they may need more money. 

I thought that using a percent withdrawal meant your income from that was the income (plus SS) on which you decided to live. And perhaps aside from a separate emergency fund, all spending was to come from the withdrawal amount. 

In other words, the $40,000 in the example is analogous to pension income. Do I have this wrong?

The 4% rule generally assumes retirement savings are the primary source of income, supplemented by Social Security and an emergency fund. The 4% you withdraw is equivalent to your pension income, the amount you decide to live on, while your emergency fund and other income are an additional buffer and are not included in this 4%. In other words, 4% is not a fixed spending ceiling, but a guide to ensure long-term sustainable spending.

You’ve explained it really well, and I agree with your analogy to a pension or salary—that’s essentially how the 4% rule is meant to work. The “expert” you mentioned isn’t wrong in saying real-life spending doesn’t follow a neat percentage, but that’s also why many people view the 4% rule as more of a guideline than a rigid formula. It’s designed to give you a sustainable baseline withdrawal rate over a 30-year retirement horizon, not to account for every unexpected expense along the way.
That’s where an emergency fund, or even a “flexible spending” mindset, comes in. Some retirees adjust their withdrawals slightly up or down depending on markets and needs—almost like giving themselves a raise or tightening the belt in certain years. So in practice, it’s less about locking yourself into exactly 4% every year and more about having a framework to avoid depleting your portfolio too quickly.
Do you think you’d feel more comfortable with a strict rule for withdrawals, or do you prefer a flexible approach where spending shifts a little depending on life events and market performance?

Well we know you ‘d be ill suited to anything other than a fixed annuity because of what you have said in the past. But your temperament doesn’t speak for everyone who by necessity has to determine and adjust to their own withdrawal strategy.

From my perspective it seems like it would be nuts to keep drawing X each month regardless of need, paying tax on drawdown and having to do additional transactions to park it elsewhere. I’d rather (unless there were particular tax advantages I was trying to avail of) have it continuing to accrue and build my “buffer” in the principal.

Again, we know you wouldn’t do this because it might involve having to track said buffer in say that most evil of things, a spreadsheet.

I think your opinion of retirees in general is rather patronising. For everyone who can only budget by receiving an amount in their checking account each month and hoping it lasts the month I hope there are at least some who draw according more to their needs rather than blindly. And yes that sometimes means being careful to define “needs” – I do not see a desire to replace multiple white goods because of a failure in one item as a “need”.

And as for not being comfortable in adjusting withdrawal strategy based on market performance – intuitively this may seem sensible on the what goes up might come down principle. But it’s forgetting that the 4% rule is statistically predicated on worst case scenarios i.e. it should hold from any point in time even if the worst sequence of returns known in history occurs.

Thus if your answer at T0 is $1m*4% = 40k and at T2 your portfolio happens to be worth $1.2m you could theoretically rebase to 48k and reset the clock.

But you’re in the wrong place if you’re trying to be this prophet preaching this mythical “simple consistent guide” as people here have read widely, done their own modelling and testing, understand maths and stats and have their own views on risk.

Not that I believe with investment portfolios being highly variable in performance, taxes being what they are and subject to tampering and any number of convoluted rules wrappers anything can be ever “simple”.

I see 4 broad categories of people.

1) Those who never have much of a portfolio to need to manage drawdown. They’ll be living on SS, pension or further earnings as best as they can.

2) Those who do not do anything to take control of a portfolio. They might over or under draw. In some cases they might not even know how much they have stashed (or had stashed for them by benefactors). Generally they’ll be as prudent or profligate as they’ve always been in their lives.

3) Those who act following advice of an advisor. This is bread and butter for Financial planners and PFAs. A good one should ensure that individuals don’t need to worry (and perhaps encourage them to spend upwards and not always make the safety first call). But obviously this comes at a price.

4) Those who are confident making their own strategy and flexing decisions within that. This is either through education or having sufficient surplus/excess assets that they can’t really stuff it up.

You sound like you’re aspiring to help Cat 2 people. But by projecting your own neuroses and biases on to situations it seems unlikely you will be the great prophet.

Your pension does change. It loses value to inflation every day. Mine is worth about half what is was twenty five years ago.

Retirees are hardly the only group of people faced with unexpected expenses. Most people find ways to cope, usually an emergency fund. Nothing about the 4% rule says you can’t have an emergency fund in addition to your main portfolio.

All spending does not have to come from that withdrawal amount and that $40,000 is not analogous to pension income because there are significant differences between a pension and a personal retirement account.

It has been stated many, many, many times that 4% (or 4.68%) is merely a starting point. Some, such as Christine Benz over at Morningstar advocate a more flexible approach in which withdrawals may include guard rails, awareness of market returns, etc.

I’ve seen “experts” make the argument that a 3% withdrawal may be too much! There are hundreds of financial related channels on YouTube with thousands of videos. There are probably a few that will make the case that 10% (or better) annual stock market returns are the new normal and so, even a 5% withdrawal rate is simply too little.

If I dig deep enough I’m sure I’ll find a few who will say whatever it is that I want to hear. That doesn’t make it accurate, prescient or prudent.

Dick, I think you’re right. The 4% number may be right or wrong, but the expert’s objection to it makes no sense. 

The commenter is probably right that few people actually live according to the 4% guideline. Also, unlike a pension, if it turns out one needs more than 4% this year, then they do have the option of taking it.

But it’s not a foregone conclusion that’s what will happen. Recognizing there may be an impact on the overall plan if they do this too much, some people may choose to forego whatever “need” was pushing them over the top. Indeed some will take the money, perhaps most, but that’s not the point, and it doesn’t “debunk” anything.

You wrote “I thought that using a percent withdrawal meant your income from that was the income (plus SS) on which you decided to live. And perhaps aside from a separate emergency fund, all spending was to come from the withdrawal amount.”

That’s the way I see it.

There are several things going on here. 

1.    What’s the value of YouTube videos?
2.    What’s the difference between a pension that provides a $40,000 annual stipend and a retirement portfolio that provides the same amount?
3.    Are there restrictions on how the money is spent?
4.    Is 4% an adequate withdrawal from the retirement account and if not, what then? What if I need more than the pension stream provides? What about long term care?

First, YouTube channels owners are not vetted. Many are influencers and not much else. Some of the videos have provocative titles. That’s a definition of click-bait. I consider most videos to be a starting point, and there may be omissions and other errors.  

A pension may have a death benefit. It may be an annuity or lump-sum benefit. This varies.  A retirement portfolio which generates $40,000 a year with a 4% withdrawal implies a value of $1 million to heirs, ignoring any taxes. A pension which provides $40,000 a year may not provide a $1 million lump sum to the beneficiary.  

A retirement portfolio has some advantages. 1) Withdrawals are flexible. There is no “hard and fast” annual withdrawal number except as dictated by the IRS RMD, and RMD amount is increased each year. 2) Portfolio withdrawals don’t have to be spent. 3) On the death of the owner, all the remaining proceeds go to the beneficiaries. This can be substantial. Pensions may not do this and there may be reduced benefits. 4) Portfolio withdrawals can fund Long Term Care and unusual health care requirement. An ample portfolio can negate the need for LTC insurance. This is not usually available with a pension.  

Funds from a pension or retirement portfolio can be spent in any manner one wishes. Need $40,000 + SS to live? Yet, you also want to take that “Bucket List “ Vacation around the world? No problem with a portfolio. Take the withdrawal, pay any taxes due. Of course, one should determine if the remainder of the portfolio is sufficient prior to proceeding.

Is 4% withdrawal adequate? If the pension is fixed at $40,000 per year, that may be a restraint. If $40,000 isn’t enough in a year due to unforeseen circumstances, one can take more from a retirement portfolio. Taking an additional 1% is an additional $10,000 before taxes; if the value has decreased to $500,000 that 1% will be only $5,000. If it is in a Roth, there will be no income taxes. I experienced this when I became gravely ill in 2022. I took a rather large withdrawal from my Roth IRA. There were no tax consequences, and an unspent amount was saved for a rainy day.  

Pensions, like annuities, may require no financial action or decisions by the recipient, other than paying any tax due. Retirement accounts require calculating the annual RMD and determining where those funds are to come from. Sell stock or bonds? The IRA broker or an accountant can calculate the RMD amount each year. There may be taxes of some of the proceeds are in taxable (brokerage) accounts.

A retirement portfolio can be designed to generate substantial dividends and interest, requiring infrequent fund sales to generate additional cash. If comprised of Target Date Funds, every couple of years a few shares can be sold and put into very short-term bond ETFs, a money market fund, etc. =
If one wants fully automatic portfolio maintenance, that can be done, but there may be additional fees. These may be 1% annually but can provide peace of mind and full automation of the portfolio. 

The above is by no means complete. Simply some of the things I’ve considered with regards to providing for my spouse when I depart. I view an annuity and a pension as having similarities.

If you are going to reference random YouTube videos then the value of such is absolutely relevant to the discussion.

Yes the 4%SWR assumes steady withdrawal plus inflation.

No it doesn’t account for additional lump sum withdrawals because they could be anything. They do not necessarily put the strategy in jeopardy because their impact is very much related to quantum and timing. A major house rebuild in year one might, an extra $10k after years of strong equity growth probably wouldn’t have any impact at all.

But to ask these questions betrays that you don’t understand the purpose of the rule. It’s not to set in stone the “income” a person receives. It’s to provide a sensible guardrail to the amount they can safely draw without fear of running out of money over a 30 year period.

The debate is usually over whether it is too conservative given the way markets have historically performed and thus leaves too much unenjoyed or conversely how resilient it is to black swan downturns.

Focus on the concept, nothing to do with the source of the question. . You either agree with the issue raised or you disagree.

I answered your question just not in the way you like so now you’re sea-lioning again. Perhaps not even sea-lioning given the baldness of your command.

Do people stick with a steady withdrawal percentage or not and if they do not are they putting their income plan at risk. That’s it, that the question.

And you’ll have to do your own research on that. I’ve given reasons why it may or may not matter.

FWIW my belief is that anyone who has the discipline to accrue a significant portfolio such that the SWR is going to serve them well also probably has the nouse to maintain a separate emergency “pot” or to flex their spending below the “rule” to give such headroom. I’d suspect that more people using the “rule” consciously underdraw on average than overdraw.

But I think you’re really scratching for reasons to crap from height on the 4% rule as something that doesn’t fit with your worldview. It’s never going to be the complete answer to retirement as it does nothing about the expenditure side (budgeting, essentials vs discretionary, capital vs revenue). Reality is that most of those fortunate to be choosing discretionary retirement (as opposed to forced) also are capable of turning off or on elements of expenditure through their retirement as other needs emerge.

I would like to help with your confusion; a noble effort on my part,

I would like you to pick one of two people you would like to be at retirement. Person A, has a pension that will pay $40,000 per year and at retirement will start collecting SS of $36000 per year. Person B has a $1000,000 taxable investment portfolio and will also collect $36000 in SS at retirement.

Person A has no savings or financial assets except what has been described. Person B has only what has been described.

In their first year of retirement, they will both face an unexpected $8000 roof repair.

Who would you like to be and why?

Speaking only for myself, whatever guideline or “rule” I might choose as a withdrawal strategy, a key consideration is at the beginning of each year, I start over and recalculate. Takes less than a couple minutes to do.

As I mentioned in a recent side note to Dick, all my spending comes from the year’s planned distribution, meaning I escrow cash each month earmarked for future unpredictable but inevitable large expenses, such as new car purchases, home remodeling and repairs, and of course our contributions to six 529 plans.

I violated my own rule for the first time this month, selling some shares of stock from a brokerage account to supplement the net proceeds from sale of our previous home in order to pay for the one we just moved into. Obviously, our nest egg took a hit, and we will recalculate our withdrawal for 2026. But we have been getting by with 2.5% per year for the past 7 years so I am not worried.

Another contributor (I forget who) mentioned Karsten Jeske Ph.D. of http://www.EarlyRetirementNow.com While he is prominent in the FIRE community, his writings are in depth and enlightening. He gives the higher level math he uses but also clearly explains it to folks like myself. His SWR series includes some 60 or so posts. Some of the engineering types on this cite along with Adam and others would probably enjoy some of the intricate
findings. Suffice to say he is not a fan of exceeding 4% as a safe withdrawal rate assuming a 30 year year horizon. Even if you don’t want to spend hours slogging through the posts, he offers a free downloadable “tool” in which you can plug in your own numbers, select your time horizon, and percent if any, of residual real portfolio value at the end of the specified period.

The 4% rule has become an oversimplified meme. If you sincerely want to understand what Bill Bengan was trying to do I would recommend reading his original paper and avoiding YouTube. His assessment was extremely conservative. As Bengen frequently states, his original study showed the actual minmum SWR was 4.15%, but it was rounded down to 4%. The paper shows that at a 4% withdrawal rate, in all the historical cases he considered, the portfolio lasted at least 35 years. At a 5% withdrawal rate in all cases considered the portfolios lasted at least 20 years,.and more than 75% lasted 30 years or more. So there would appear to be some margin of safety for occasional extra needs.

The obvious difference between portfolio withdrawals and a pension is the pension doesn’t grow. For example, consider someone who retired at the beginning of 2024 with $1M who withdrew $40,000 on Jan1. The remaining $960,000 invested in a 50/50 portfolio grew at about 6.7%, so the portfolio value at the end of year was $1,024,320. If you have some fortunate years of investing, there is an opportunity for increased withdrawals beyond the inflation adjustment. Sadly, my pension does not allow for that.

The 4% is the Safe Withdrawal Rate (SWR), not a Safe SPENDING Rate. It is just a way to turn one’s retirement savings into an annual paycheck based on market historical returns. How you spend this “retirement paycheck” is determined similar to the way you did previously with your work paycheck.

If you use the 4% SWR as proposed by the research paper, then no deviation. I know absolutely no one who lives life by implementing economic theory. If you use it as a heuristic to arrive at a reasonable assumption of how much is required before even considering retirement, then I guess it depends on your own personal strategy.

Mark Crothers

Ad hoc lump sum withdrawals beyond the 4% will reduce the likelihood of the strategy successfully lasting the 30-year time frame. That’s just how it is…just don’t ask me for the probability and failure curves, that’s above my pension withdrawal pay grade 😉

I think some of the problem people are having with the 4% rule is that they are taking it too literally i.e. they’re thinking concretely, rather than abstractly, in this instance. 

The 4% rule is a guideline. It is not an absolute. If you have spent your $40,000 in September on a $1 million portfolio, and the roof starts to leak, as mentioned below, you go beyond the 4% “barrier” and you take the money out of your portfolio and fix the leak.

Clearly adjustments will need to be made in the future – perhaps drawing less than 4% in subsequent years, or earning income in some fashion, to maintain the portfolios viability for the future.

Never has anyone said or implied that you can’t EVER spend more than 4%. As we all know, spending tends to fluctuate from year to year, therefore, for people who live close to the edge, if they do need to go over 4% in a given year, they would then need to make adjustments subsequently. 

Now for the fun part ! What do you think of immediately after reading the next sentence? 

“The squeaky wheel gets the grease”…….. 

Those who think concretely answer that the bicycle tire that’s squeaking or car tire that’s squeaking, will be the one to get the grease to stop the sqeak.  

Those who think abstractly respond that someone who speaks up, and/or makes a nuisance of themselves, or does something to make themselves noticed, will be the one that gets the attention or be noticed.  

Still my favorite pearl from my Psychiatry rotation in Med School !

For a more complete explanation – Googles AI response:

A concrete thinker relies on literal interpretations and facts from the observable physical world, focusing on tangible objects and present circumstances rather than abstract concepts, metaphors, or inferences. This thinking style is a literal form of reasoning that takes information at face value and is closely associated with the developmental stage of early childhood, though it remains a valid approach for many adults. Concrete thinking contrasts with abstract thinking, which involves conceptual, philosophical, and imaginative reasoning beyond the immediate and tangible. 

Characteristics of Concrete Thinking

  • Focus on the Literal:Taking information and statements at face value, without delving into deeper meanings or interpretations. 
  • Emphasis on Facts:Grounded in what is observable, tangible, and verifiable in the physical world. 
  • Reliance on the Five Senses:Information is often processed based on what is seen, heard, touched, smelled, or tasted. 
  1. Difficulty with Figurative Language:May struggle to understand idioms, jokes, or metaphors, which require abstract interpretation. 
  2. Sequential and Practical:Prefers clear, step-by-step instructions and practical applications rather than conceptual ideas. 

Concrete vs. Abstract Thinking 

  1. Concrete Thinking:Focuses on specific, observable details and the immediate physical world. 
  2. Abstract Thinking:Moves beyond concrete facts to connect concepts, form generalizations, and explore theoretical or philosophical ideas.

I’m not 100% sure I’m understanding what you’re saying ? Did you mean to say “can” rather “can’t” in the first line ?

I think we should view 4% as a guideline rather than an impenetrable barrier than can never be crossed. Going over ones threshold percentage a small number of times (don’t know how many), without extreme over withdrawals (don’t know much), is not likely a big deal.

One can certainly deviate from spending 4% though that will lead to an increase in the likelihood of portfolio failure, but it is certainly not an all or none situation- going from a 4% spending rate to 4.25 or 4,5 % spending rate reduces the likelihood of portfolio success, but by no means is it a guarantee of failure. Even less so with a bit of time to make future adjustment downwards if needed, as I mentioned.

It would be very helpful if you defined “failure” and your cited your sources. Bengen’s study was about portfolio longevity. As I presented in the comment above, the analysis of historical worst-case returns showed 4.15% provided at least 30 years portfolio longevity in all cases, and 5% withdrawal provided 30 or more years in 75% of cases, and at least 20 years in all cases. So if a retiree takes modest extra withdrawals, failure might mean their portfolio lasts 28 or 29 years. And that is in the worst market conditions we’ve experienced.

Your Google response said “A large lump sum withdrawal fundamentally changes the equation by significantly reducing the total amount of money you have invested.” Spending $500K on a boat would have an impact. Your example of a $15K repair on a $1M portfolio hardly meets that definition.

Dick, doesn’t it just boil down to basic money management? Whether our income is from salary, pension or savings (4%), we live on what we have. Those without savings, but with reliable income from another source, might borrow money to fix the roof–if they don’t have an emergency fund to cover it. If we take an extra lump sum from savings for a large purchase, then we have to consider it “borrowed money”, and “pay it back” by reducing future spending. We also need to consider that we lost some growth of the money we withdrew early.

For those of us without a pension, the 4% is analogous to a pension. But like the youtube dude says, you may have additional needs beyond 4% on a given year. 
I equate this to living paycheck to paycheck during one’s working years, and not having an emergency fund. I contend that if  retirees are going to spend the entire distribution, they’d better have adequate emergency funds available aside from the account(s) they live from. 
I’m even more conservative; we do everything we like and use far less than 4%. I feel no need to force myself to spend more.

Interestingly, I think you’re both right. You understand it exactly as it is designed.

But, he’s probably right that no one actually does retirement that way. For me, as a pre-retiree, the 4% rule is helpful to understand how much I need to save to live on $Y per year. In other words, whatever I think I’ll be spending per year, I should save 25X that amount for safe withdrawals given the sequence of returns risk.

Whether I will actually pull out exactly 4% per year or any such amount is unknown, but probably not make or break. If it’s 3.5% or 4.5% it’s probably prudent to keep it somewhere in that general range.

If you have all your assets under the 4% SWR regime, then yes—no further withdrawals beyond your yearly distribution can occur with a true implementation of the scheme. Personally, I don’t use the system. If I did, I would have a substantial cash balance and maybe even a small balanced portfolio outside the scope of the SWR structure.

To be clear, SWR is a rigid framework that brooks no deviation from its core tenets. It works as an economic textbook theory, but I feel it doesn’t translate into real-world reality.

Totally agree. Use the SWR for your “pension” and seperate funds for any top-up beyond the 4%
