How the 4% Rule Is Actually Holding Up for Real Retirees

Quick Answer

The 4% rule has survived the dot-com crash, the 2008 financial crisis, the COVID crash, and the 2022 bear market. Retirees who started in 2000 at the worst possible time still have money 26 years later. Those who retired in 2010 or later are sitting on portfolios far larger than their starting balance. The real-world track record is better than the theory predicted, mostly because real people spend less over time and earn something in the early years.

The 2000 Retiree: The Worst-Case Stress Test

If you wanted to design a worst case for the 4% rule, you would pick someone who retired on January 1, 2000. The S&P 500 was at its dot-com peak. Over the next three years, stocks fell roughly 45%. Then they recovered. Then in 2008, they fell another 55%. Two of the worst crashes in modern history, back to back, within the first decade of retirement.

Here is what actually happened to a $1,000,000 portfolio (60% stocks, 40% bonds) withdrawing $40,000 per year, adjusted for inflation:

Twenty-five years in, having survived two catastrophic crashes, the 2000 retiree still has money. The portfolio is smaller than it started, and it got uncomfortably close to failure around 2009. But it survived. That is the absolute worst starting point in modern history, and the 4% rule held.

Barely. But it held.

The 2010 Retiree: Right Place, Right Time

Someone who retired January 1, 2010 stepped into one of the greatest bull markets in history. They did not know that at the time. In early 2010, the financial crisis was fresh, unemployment was near 10%, and most people were terrified of stocks.

A $1,000,000 portfolio (60/40) withdrawing $40,000 per year adjusted for inflation looks like this 16 years later:

The 2010 retiree has $2.4 million after 16 years of withdrawals. More than double their starting balance. They could triple their spending and still be fine. This is not unusual. This is what the median 4% rule outcome actually looks like.

The 2020 Retiree: Through COVID and Beyond

The COVID crash was fast and brutal. The S&P 500 dropped 34% in five weeks starting February 2020. But it recovered almost as fast, hitting new highs by August. The 2022 bear market followed, with a 25% decline driven by inflation and rate hikes.

Six years in, a $1,000,000 portfolio (60/40) withdrawing $40,000 per year is worth approximately $1,200,000 to $1,300,000. The 2020 retiree has weathered two significant drawdowns and is still comfortably above their starting balance.

That is the thing about the 4% rule. It was designed for the worst-case scenario. Most of the time, you end up with more money than you started with.

What Real Retirees Actually Do

The academic models assume a robot that withdraws exactly 4% (inflation-adjusted) every year regardless of market conditions or personal circumstances. Real humans do not work that way. And their behavior, it turns out, makes the 4% rule even more durable.

Spending declines with age

Research by David Blanchett at Morningstar found that real retirement spending follows a "smile" shape. Spending is high in the early, active years. It drops in the middle years (the "go slow" phase). It may rise again late in life due to healthcare costs, but the middle dip means most retirees spend less than projected for 10 to 15 years. Blanchett estimated real spending declines by about 1% per year after inflation in the early decades of retirement.

A retiree who plans for $40,000 per year might actually spend $35,000 by year 10 and $30,000 by year 15 in real terms. That is not a sacrifice. It is what happens when you stop buying furniture, stop traveling as aggressively, and settle into routines.

Most retirees earn something

The FIRE community calls this "one more year syndrome," but the data shows it is more like "a few more dollars forever." Bureau of Labor Statistics data shows that 25% of Americans aged 65 to 74 do some paid work. Among early retirees (50 to 64), the number is higher. Consulting, part-time teaching, freelancing, board positions. Even $10,000 to $20,000 per year of earned income in the first decade drops the effective withdrawal rate from 4% to 2.5 to 3%.

Social Security changes the equation

A 50-year-old FIRE retiree has 12 to 20 years before Social Security kicks in. Once it does, the required portfolio withdrawal drops sharply. A couple receiving $40,000 per year from Social Security might go from a 4% withdrawal rate to a 1.5% rate overnight. At 1.5%, the portfolio is essentially indestructible over any historical period.

The Failures Are Clustered

When you run the 4% rule across every possible 30-year retirement starting point in U.S. history (1926 to present), it fails roughly 5% of the time. Five out of every hundred starting years leave the retiree broke before year 30.

But those failures are not spread randomly across history. They are clustered in a few specific windows:

• 1929 to 1930: The Great Depression followed by World War II. Stocks fell 80% and took 25 years to recover in real terms.
• 1966 to 1968: The beginning of a 16-year period of high inflation and flat real stock returns. A retiree starting in 1966 faced simultaneously rising costs and stagnant portfolio growth.

That is it. Two clusters. Every other 30-year period in U.S. history, the 4% rule worked. Most periods left the retiree with far more than they started with.

The 2000 retiree looked like it might join this list. It did not. And even the 1966 retiree only ran out in year 29 or 30 at a strict 4% withdrawal, meaning even slight flexibility (cutting spending by 5% in bad years) would have saved them.

The Median Outcome: Dying Rich

This is the part that gets lost in the "will I run out of money?" anxiety. The median outcome of the 4% rule is not scraping by. It is dying with 2 to 3 times your starting balance.

Run the numbers. Across all historical 30-year periods, a $1,000,000 portfolio with $40,000 inflation-adjusted withdrawals has a median ending balance of roughly $2,500,000 to $3,000,000 in real terms. The 4% rule's 5% failure rate is also a 50%+ "you will leave a massive inheritance" rate.

John Bogle put this well: the real risk for most disciplined investors is not running out of money. It is spending too little and dying with a fortune they were afraid to touch. The 4% rule is deliberately conservative. It is calibrated to survive the worst. In an average or good market, it leads to severe under-spending.

This has a practical implication. If you are 10 years into retirement and your portfolio is above your starting balance, you can spend more. Recalculate. You are no longer in danger. The safe withdrawal rate analyzer can help you model updated withdrawal rates based on your current balance and remaining time horizon.

What Matters More Than the Rule Itself

The 4% rule is a starting point, not a suicide pact. The retirees who do best share a few traits:

• Spending flexibility. Cutting discretionary spending by 10 to 15% during bear markets buys enormous portfolio longevity. Going from $40,000 to $34,000 for two years is not fun, but it is not catastrophic either. And it can add 5 to 10 years of portfolio life.
• Low fees. A 1% annual advisory fee on a $1,000,000 portfolio is $10,000 per year. That is 25% of your withdrawal budget going to your advisor. Index funds at 0.03% to 0.10% keep almost all of the returns in your pocket.
• Tax efficiency. Roth conversions, tax-loss harvesting, and managing capital gains brackets can save $5,000 to $15,000 per year in taxes. That is real money that stays invested.
• Ignoring the news. The retirees who check their portfolio daily and panic during crashes are the ones who break the rule. The ones who set up automatic withdrawals and go hiking are the ones who succeed.

Frequently Asked Questions

Should I use 3.5% instead of 4% to be safer?

You can, but understand the tradeoff. Going from 4% to 3.5% on a $1,000,000 portfolio means spending $35,000 instead of $40,000 per year. That is $5,000 less per year, every year, for potentially 30+ years. Over 30 years, you are giving up $150,000 in spending (not inflation-adjusted) to protect against a 5% historical failure rate. If you have any spending flexibility at all, sticking with 4% and being willing to cut 10% in bad years is a better strategy than permanently living on less. See our full analysis of updated safe withdrawal rates for more detail.

Does the 4% rule work for 40 or 50 year retirements?

The original Bengen research tested 30-year periods. For 40 to 50 year retirements (typical for FIRE), the safe withdrawal rate drops to roughly 3.25% to 3.5%, depending on your assumptions. But remember: Social Security kicks in eventually, spending declines with age, and most early retirees earn some income in the first decade. The effective withdrawal rate for a 40-year-old FIRE retiree is usually well below their nominal rate.

What if we get a "lost decade" worse than 2000 to 2010?

The 2000 to 2010 period was already one of the worst in U.S. market history. Stocks returned roughly 0% nominal over the decade. Even in this environment, the 4% rule survived (barely). A truly worse decade would require something historically unprecedented. Possible, but the defense is the same: spending flexibility, diversification, and a cash buffer for the first few years. Read our analysis of what happens when markets crash after retirement for specific scenarios.

Do international markets change the picture?

Wade Pfau tested the 4% rule across 17 developed countries. The U.S. had some of the best outcomes. Countries with lower stock returns, higher inflation, or wartime destruction (Japan, Italy, Germany) had lower safe withdrawal rates, sometimes around 2 to 3%. The 4% rule is a U.S.-centric number. If you are diversified globally, 3.5% is more conservative and accounts for the possibility that future U.S. returns look more like the global average.

What about inflation like the 1970s?

High inflation is already baked into the data. The 1966 to 1968 retirement cohorts faced double-digit inflation for over a decade, and those are the borderline failure cases. The 4% rule survived them (just barely). The defense against a repeat: TIPS (Treasury Inflation-Protected Securities) for the bond portion, stocks for long-term inflation hedging, and the willingness to cut spending when real returns are negative.
