What Is a Safe Withdrawal Rate in Retirement?

The number everybody quotes comes with a set of assumptions nobody mentions. Here’s what it actually promises, and what it doesn’t.

Already have a number in hand and trying to measure it against something you read? Skip ahead to how a guaranteed lifetime withdrawal benefit compares.

Want to know what your own savings would produce, both ways, before you decide which number to trust? That’s what this call is for. Fifteen to thirty minutes, no cost, no pressure.

Where did the 4% rule come from?

Can I ask you something before we get into the math?

When somebody hands you a rule about your money, do you ever find out where it came from? Most people never do. They just hear the number often enough that it starts to sound like a law.

Here’s where this one came from.

In 1994, a financial advisor named William Bengen went looking for an answer to a question nobody had studied properly. How much could a retiree pull out of their savings each year without running out of money?

He took decades of American market history and ran a retiree through every thirty-year stretch of it. Retire in 1929, right before the crash. Retire in 1966, right before a brutal decade of inflation. Every starting year he could test.

What he found was that a retiree who took out 4% in year one, then gave themselves a raise each year to keep up with rising costs, made it through all of those thirty-year windows without running dry. Not most of them. All of the ones his data covered.

That is the whole origin of the number you’ve been quoted.

It was a real piece of research, done carefully, and it was a genuine step forward at the time. Bengen himself has revised his figure upward in later work, and other researchers using different assumptions have landed noticeably lower. The number was never meant to be a law. It was a finding.

Now here’s the question worth taking with you into the rest of this page.

If a number came from testing what already happened, what exactly is it telling you about what happens next?

What are the 4% rule assumptions?

Every rule about money is built on a set of assumptions. Change one assumption and the number moves. Most people never see the list, so let me put it in front of you.

The research behind the 4% figure assumed a retiree who:

• stops working at a typical retirement age and needs the money to last about thirty years
• holds a specific mix of stocks and bonds and keeps holding it, through every crash, without flinching
• gets returns roughly in line with what American markets delivered in the past
• pays no fees on any of it
• pays no taxes on any of it
• and increases their spending by the same amount every single year, in a straight line, for thirty years

Read that list again and ask yourself two simple questions.

How many of those describe you?

How many of those happen in the real world?

The fees and taxes are the obvious ones, and they matter. Every dollar of fee and every dollar of tax comes out of the same account the withdrawals come from, and neither one was in the original math.

Two of the others deserve a closer look, because they are the ones that quietly do the most damage.

The first is the straight line

The rule assumes you spend a little more every year, forever, in a smooth upward line.

Does that sound like what happens in real life?

David Blanchett, Head of Retirement Research at Prudential Financial, published research in 2026 tracking how retiree spending actually moves over time. What the data shows is that spending tends to drift down in real terms for most retirees, while a minority face a sharp late rise, usually from the cost of care rather than the cost of living.

Research suggests spending declines slightly each year in retirement unless care costs increase later in retirement.

Here is the part that ought to stop you.

Even retirees with more than enough money reduced their real spending. They could have spent more. They chose not to.

Think about what that means for a rule built on the opposite assumption.

The second is the order things happen in

The rule assumes an average. Markets do not deliver averages. They deliver a sequence of returns, and the sequence of returns you happen to get is not something you choose.

Research by Wade Pfau found that roughly 77% of your portfolio outcome is decided by the sequence of returns in your first ten years after retirement begins. Not the thirty-year average. The first ten years.

Two retirees can live through the exact same thirty years, retire five years apart, have the same average return, and end up in completely different places. Same rule. Same percentage. Same discipline. Different luck.

Now the question this section has been building toward.

If the number assumes no fees, no taxes, spending that behaves in a way most retirees do not, and market returns arriving in an order nobody can pick, what is it actually promising you?

What is a safe withdrawal rate by age?

Here’s a question almost nobody asks when they hear the 4% figure.

At what age?

The research behind that number was built around a retiree who stops working around a traditional retirement age and needs the money to last about thirty years. That is one age and one length of retirement. Change either one and you are no longer looking at the same problem.

Picture two people.

The first retires at 70. The money may need to last twenty years or so.

The second retires at 55. That same money may need to last forty years. Twice as long.

Same savings. Same percentage. Completely different job.

The direction here is not a matter of opinion, it is arithmetic. A shorter retirement can support a higher withdrawal rate. A longer one supports less. Where exactly the number lands for any individual depends on every assumption we walked through in the last section, which is why you will find published figures all over the map. Any figure you see, including the 4%, is illustrative and hypothetical.

Now here’s the part that gets missed, and it matters more than the percentage.

Retiring earlier does not just stretch the money over more years. It also puts more of your savings in front of that first decade Wade Pfau was talking about, and it does it before Social Security has started paying you anything.

Pfau’s model was built on a thirty-year retirement. Nobody has run it on forty. When you hear “the first ten years,” understand what that number is attached to.

Here’s my own thinking, and I’ll tell you plainly it’s judgment, not research. Stretch a retirement from thirty years to forty and you’ve added ten more years of pulling money out of an account that’s fully exposed, with no Social Security arriving yet to share the load. Does the risky stretch stay exactly ten years? I doubt it. Is it eleven, twelve, fifteen? I don’t know, and neither does anybody else, because the research doesn’t go there.

What I’d rather you take from it is this. Don’t fixate on ten. Ask yourself instead how many years you’d be carrying the whole thing alone, and whether you want that many years riding on the order the market happens to show up in.

Think about what that means. The person who retires at 55 is drawing the heaviest withdrawals of their life out of an account that is fully exposed to the market, in the exact stretch of years that decides most of the outcome, with no other income coming in the door yet.

The person who retires at 70 is drawing on top of a Social Security check that has already started.

Same market. Same percentage. One of them has a cushion the other does not.

And it isn’t only about retiring early. Picture someone who retires at 65, but takes care of herself, stays active, and comes from a family where people live into their nineties and past a hundred. She isn’t planning a thirty-year retirement. She’s planning a thirty-five or forty-year one, whether or not anyone has said that out loud to her.

Most people never do that math on themselves. They hear “thirty years” and assume it covers them, because thirty years sounds like a long time.

Ask yourself the plain question. How long do the people in your family tend to live? And how are you treating your health right now?

That is why a safe withdrawal rate by age is a real question and not a technicality. The age you retire changes how long the money has to last, how much of it is exposed when exposure hurts most, and how many years you carry the whole thing by yourself.

Let me ask you the question this whole section leads to.

If the number changes with your age, your horizon, your fees, your taxes, your spending, and the order the market happens to arrive in, is it a withdrawal rate you can plan a life around? Or is it an estimate you are asked to trust for thirty years or longer and then live with whatever it turns out to be?

How does a guaranteed lifetime withdrawal benefit compare to a safe withdrawal rate?

If you have been handed paperwork on a contract that pays lifetime income, you have probably seen this phrase. Guaranteed lifetime withdrawal benefit. It usually gets explained in language nobody outside the business would ever use.

Here it is in an easy-to-understand format.

It is a feature on certain insurance contracts that guarantees you can take out a set amount every year for the rest of your life, no matter what the market does and no matter what happens to your account balance. If the balance runs to zero and you are still living, the payments keep coming. That guarantee rests on the claims-paying ability of the insurance company that issued it, which is why the strength of the company behind it matters as much as the number printed on the page. If you want it even shorter, here is the plain definition of a guaranteed lifetime withdrawal benefit on its own page.

Here is the part that answers what most people are actually afraid of. On many of these contracts, if you die before you have taken out everything in your account, what is left goes to your heirs. Not to the insurance company. That is different from a life-only arrangement, where the payments stop at your death and nothing passes on, and it is worth asking about by name on any contract you are shown, because the answer depends on the contract and on the options you select.

This is the piece I call Protected Lifetime Income, and it is what we use to build the income floor underneath your retirement.

Now the part this whole page has been walking toward.

Two numbers that look identical and are not

Both get expressed as a percentage of your savings. Both get called a withdrawal rate. You compare them straight across, one against the other, and take the bigger number.

They are not the same kind of number.

A safe withdrawal rate is a probability. Based on what markets did in the past, there is a reasonable chance your money lasts about thirty years if you take out this percentage and give yourself a raise each year. Nobody is standing behind it. If the sequence of returns you get is worse than the ones in the study, your money runs out and the study is still correct.

A guaranteed withdrawal rate is a contract. You receive this amount for as long as you live, backed by the insurance company’s claims-paying ability.

There is no probability attached to it and no thirty-year assumption underneath it. It does not stop at thirty years, or forty. And if you are married, it can keep paying whichever one of you is left.

Let me show you the difference another way

Picture your savings as a lake.

Not a river. A lake. It holds what it holds.

A withdrawal rate, safe or otherwise, is the size of the bucket you dip into that lake each year. Somebody hands you a study and tells you which bucket is the safe one. Fine. But a bigger bucket is still a bucket, and every bucket comes out of the same lake. The water level drops. And in a dry stretch, it drops faster than you planned.

Guaranteed lifetime income is not a bucket. It is a river running into your yard.

The river flows at the same rate whether the lake is high or low. It does not care what the market did last year. It does not stop when the lake runs out. And if you are married, it keeps flowing for the one still standing there.

Now here is the part that has nothing to do with math, and it is the part I watch happen to real people.

Droughts are normal weather. The shoreline pulls back in almost every year, including good ones. And when you stand there and watch your water go down, do you reach for a bigger bucket, or do you ration?

Do you skip the trip?

Do you put off the visit to the grandkids.

Do you tell yourself next year, when things look better?

That is the thing nobody warns you about. It is not that the lake runs dry. It is that you spend your retirement staring at the shoreline, deciding every morning whether you are allowed to spend your own money.

Let me be blunt with you.

Is that how you pictured it?

Your real trade

Being straight with you, there is a genuine trade here, and anybody who does not name it is selling you something.

A safe withdrawal rate gives itself a raise every year. That is built into the research. A guaranteed payment does not. It is flat. The dollar amount that arrives in year one is the same dollar amount that arrives in year twenty.

That is a real difference, and it is exactly why the guaranteed number often looks higher at the start. You are being handed a flat payment to compare against a rising one, and nobody tells you that is what you are doing.

Why would you ever choose flat?

Three things worth your consideration.

First, you are not building your whole retirement out of one piece. Social Security already sits inside your income floor, and Social Security carries its own cost-of-living adjustment. You already own a piece that rises. The question was never whether every dollar of your income adjusts. It is whether enough of it does.

Second, when a guaranteed payment is built to adjust for inflation, the starting amount comes down, often considerably. Every scenario we run with an adjusting structure leans harder on the market and on the index inside the contract, and you start out with less income in hand during the years you are healthiest and most able to use it. That is my professional judgment, from running these numbers for the people who sit across from me.

Third, and this is the piece almost nobody hears: your spending will probably not rise in a straight line. We covered that research earlier on this page. Real spending tends to drift down for most retirees. A flat guaranteed payment against a need that eases over time covers a growing share of that need as the years go by. The income never rises. Your need shrinks toward it.

That can help offset rising costs. I want to be careful with my words there, because it is not inflation protection and it is not a promise that you keep pace with inflation. Nobody can promise you that.

What the same million dollars does

We just walked through what the 4% rule produces. A million dollars, $40,000 a year, with a probability attached and nobody standing behind it. If you use 4.7% instead, it’s $47,000.

Now let me show you the same million dollars run the other way. These are current figures as of July 2026, illustrative and hypothetical, and they move with rates and with the carrier.

If you are married, both age 65 and want income starting now, that same million dollars produces about $76,800 a year, guaranteed for life. (It’s a little bit more if you’re single and 65).

At 67, about $78,000. At 70, about $82,000.

Read that against $40,000 one more time.

Same million dollars. Roughly twice the income. And the second number does not come with a thirty-year assumption, a market forecast, or a probability. It comes with a contract behind it.

Now let me tell you why we would never actually do that.

The right amount, never all of it

Traditional planning takes everything you have and points it all at one job. That is the thing I spend my days arguing against, and we are not about to turn around and do the same thing with a different product.

We would not put your entire million into a contract. Not close.

Here is how the sizing actually works.

We start with your life, not your balance. What does your year actually cost? Not just the essentials, the housing and the groceries and the insurance, though those come first. We are also asking about the trips you keep promising yourself, the season tickets, the fishing boat, the flights to see the grandkids, the week at the lake every summer with everybody under one roof. The things that made you save the money in the first place.

That total is your income floor. It is the number that has to show up whether the market cooperates or not.

Then we look at what already covers part of it. Social Security, and a pension if you have one. Whatever is left over is the gap, and the gap is the only thing we protect.

We use the amount it takes to close that gap, and not a dollar more.

Everything else goes into your growth account. It stays yours. It stays liquid. You can reach it any day of the week, for any reason at all, and you never have to explain the reason to anybody, including me.

For most people the protected portion lands somewhere around half. It can run higher when there is plenty of other liquidity sitting around it. It should run lower when there is not.

Which brings me to the part I most want you to see.

The runway

Here is what almost nobody understands about these contracts. The single most powerful thing you can do is start the retirement income planning clock early.

Take that same million dollars. Protect half of it, $500,000, and leave the other half in your growth account.

If you put that $500,000 in at age 55, with income starting at 65, it produces about $77,770 a year for life.

Look at that against the number above it. Half the money, given a ten-year runway, produces more income at 65 than the entire million does if you wait until 65 to start.

Shorter runways still move the needle. That same $500,000 put in at 60 for income at 65 produces about $52,900 a year. Put in at 62 for income at 65, about $45,350.

Every one of those figures still leaves you a $500,000 growth account, largely untouched and still yours.

Now the question worth serious consideration.

If starting ten years early roughly doubles what the same money will pay you for the rest of your life, what is waiting actually costing you?

All figures illustrative and hypothetical as of July 2026, based on current rates and factors that change over time, and dependent on the contract and the claims-paying ability of the issuing company.

How we handle the difference

Now back to the trade we named earlier. Your guaranteed payment is flat. Costs are not.

Here is how we deal with that, and the answer is simpler than most people expect.

We set the guaranteed payment higher at the start, and we build the income floor to cover the life you want rather than the bare minimum you could survive on. That means the early years, the healthy years, the ones where you are still climbing in and out of a boat without thinking about it, are funded generously on purpose.

Then, if costs climb and you want more income later, you take it from your growth account.

Read that again, because that sentence carries more than it looks like.

You decide. Not a formula, not a contract, and not an index buried in a document you cannot read. You look at what a year actually costs you, decide whether you want more, and take it. Or you decide you do not want more this year, and you leave it alone.

Picture a year where costs are up and the market is down at the same time. Under the old approach, that is the year you are forced to sell while everything is on sale, because that account is carrying your income. Under this one, your income floor arrives regardless. The extra pull from your growth account is optional, and skipping it for one year is not a hardship. Your groceries, your insurance, your property taxes, all of that is already covered by income that showed up on schedule.

What you would be passing on is a small adjustment on top of an income floor that is already generous. Then you take it the following year, or the year after, once your growth account has had a chance to recover.

That is what having options looks like.

There is a second thing working in your favor here, and it is the one that surprises people. Your spending is not likely to hold steady in real terms across a thirty-year retirement. For most retirees it drifts down, and the trips that cost the most tend to happen in the earliest years. When your income floor is built generously at the start, that flat guaranteed payment ends up covering a growing share of a need that is easing. The income never rises. Your need moves toward it. That can help offset rising costs, though it is not inflation protection and nobody can promise you keep pace with inflation.

We go deeper on that here: afraid to spend money in retirement and how to protect against inflation and sequence of returns risk.

Compare it to the other path. Build the inflation adjustment into the contract itself, and your starting payment comes down, often considerably. You spend your healthiest years with less income in hand, in exchange for an adjustment that arrives on somebody else’s schedule and depends on how an index inside the contract performs. Every scenario we run that way leans harder on the market and starts you lower.

That is my professional judgment, from running these numbers for the people who sit across from me.

Figures and structures discussed here are illustrative and hypothetical, and the right approach depends entirely on your situation.

Now the question this section leaves you with.

If one of those numbers describes a chance and the other describes a promise, which one do you want your groceries, your property taxes, and your health insurance riding on?

You’ve now seen both structures and the trade between them. The part a page can’t do is run your numbers. That takes your Social Security estimate, your savings, your age, and about twenty minutes.

Why does everyone quote the 4% rule?

Let me ask you something that sounds like a trick question and isn’t.

When an advisor hands you the 4% figure, do you think that’s laziness? Or do you think it’s the best answer the tools in front of them are able to produce?

For most of them, it’s the second one. That distinction matters more than any percentage on this page.

Here’s something the industry won’t tell you. The person across the desk did not build the model they’re working inside. They inherited it. Their software runs probabilities. Their compliance department approves the language that comes attached to probabilities. Their training, from their first week in the business, was built around one job: manage a pool of money and work out how much can come out of it each year without the account running dry.

Ask a model built for that job what to do about a risk that runs thirty or forty years, and it hands you the only answer it owns. A percentage, a probability, and a recommendation to hold on through the rough patches.

Now the harder question, and I’d rather you answer it than have me answer it for you.

What happens to that model if the right answer for you is that some of your savings stops being managed?

I’m not telling you anyone is lying to you. Most of the advisors I’ve known over the years are decent people who want their clients to do well. That’s exactly the point I’m making. A person can be honorable, capable, and working hard on your behalf, and still be handing you the output of a model that was never designed to guarantee anything.

The model isn’t built to protect your groceries. It’s built to project them.

Think about how that shows up in your actual life. The market drops 30 percent in your third year of retirement. The model’s answer is to stay the course and trust the average. That’s not a bad answer. It is the only answer the model has. It just asks you to absorb the sequence of returns with your own retirement while you wait to find out whether the average shows up in time to help you.

An income floor answers it differently. Your income arrives on schedule because a contract says it does, not because a probability suggests it will. The market drop is still real. It just stops being your problem to solve that month. A crash is a headline, not an emergency.

That’s the whole reframe, and it has nothing to do with who your advisor is.

The label on somebody’s business card, the letters after the name, the size of the firm behind them, none of it tells you what actually happens to your income the year the market turns. The structure does. The label protected the model. It didn’t protect the family.

You don’t have to trust a label. You can look at the structure and see for yourself.

Here’s where I’d leave you before we move on.

If the answer you were given is the only answer the model was capable of giving, was it ever really an answer about you?

Isn’t this just an annuity salesman talking?

Somebody left a comment on one of my videos a while back. Five words.

“Sounds like an annuity salesman.”

They were right.

I sell these contracts. When a client puts money into one, I get paid. That’s not a footnote I’m burying at the bottom of a page, and I’m not going to dress it up as something nobler than it is. If you’ve been reading this page thinking there’s a catch and the catch is that the man writing it has something to sell, there’s no catch. That’s exactly what I am.

Now let me tell you why I don’t think that settles anything, in either direction.

The advisor across town is paid a percentage of the money in your account, every year, for as long as it stays there. I’m paid when a portion of your savings goes into a contract. Two different compensation models, two different sets of pressure, and neither one of us is going to talk you out of ours. You could spend a month trying to work out which of us is less biased and finish exactly where you started.

Being straight with you, bias is the wrong test. It’s unmeasurable, both sides claim the high ground, and it tells you nothing about your own retirement.

Here’s the test I’d rather hand you.

Forget who’s talking. Run your actual retirement through both structures and watch what happens to your income in the years that hurt. That is the whole reason this page exists, and it’s why we spent it walking through assumptions, the sequence of returns, and what the same million dollars does under each approach. Those examples aren’t there to make me look good. They’re there because they’re what you’d be living through.

I’ll tell you where I’m coming from, and then I’ll get out of the way.

I spent about twenty years in the mortgage business before any of this, watching more than a thousand families make the biggest financial decisions of their lives, a lot of them more than once. When I went looking for something better to point those families toward, I didn’t care where the research took me. I could have gone the investment direction. Plenty of good people did. After what I’d watched happen to families’ money in the years I sat across from them, I couldn’t have done it and slept well. This is where the research put me, and it’s where I’ve stayed, because it gives the people I work with a real shot at living the life they saved for, with the important parts set up ahead of time instead of hoped for.

That’s my conviction. It isn’t evidence, and you shouldn’t take it as evidence.

What you’re owed is the cost of my side, named as plainly as I named theirs.

The guaranteed payment is flat. It does not give itself a raise, and you already read me admit that earlier on this page. Money that goes into one of these contracts is less liquid than money sitting in an account, and pulling more than the contract allows in the early years usually carries a charge. The guarantee itself has a cost inside the contract, and it varies by contract and by the options you choose. The guarantee rests on the claims-paying ability of the company that issued it, which is why the strength of that company matters as much as the number on the page.

There’s a limit on me, too. I’m life and health licensed. I’m not a securities broker, an investment advisor, or a CPA, and I don’t manage investments. That’s a real boundary on what I can do for you, and I’d rather tell you than have you discover it.

And this is not right for everybody, or for every dollar. We never protect all of it. When there isn’t much other liquidity around it, the protected portion runs lower, not higher. That question, whether these contracts are ever a fit, has its own page.

Now the question that actually decides this.

How do you solve it for your situation? Look at the examples on this page, then picture your own retirement running through both structures. The year the market drops 30 percent. The year costs jump. The year one of you is left. In each of those years, ask yourself the same plain thing.

Which one of us is biased? Or which structure puts your groceries, your property taxes, and your health insurance on solid ground in the years you can’t control?

Figures and structures discussed on this page are illustrative and hypothetical as of July 2026, and the right approach depends entirely on your situation.

Where to go from here

A page like this answers one question well and opens three more. Here’s where the rest of them live.

If the 4% figure is what brought you here and you want the fuller argument on whether it still holds up, start with whether the 4 percent rule is still safe.

If the part that stuck with you was the sequence of returns, and the idea that two people can live the same thirty years and land in different places, that one has its own page: how sequence of returns risk threatens retirees even with average returns.

If you want the short, plain version of what a guaranteed lifetime withdrawal benefit is, without the comparison wrapped around it, that page gives it to you in about a minute.

And if you’re still weighing the real pros and cons of these contracts, including the parts that don’t flatter them, read whether these contracts are safe and what the trade-offs are.

Every one of those pages answers a piece of the same question you came here with. How much can you count on, and who is standing behind it.
