When I first heard about the 5% withdrawal rule, it sounded like a reasonable compromise. Not too greedy, not too cautious. A way to actually enjoy retirement rather than pinching pennies until the very end. So when I retired at 62 with a decent nest egg, I did the math, set up automatic withdrawals, and assumed the numbers would hold.
They didn’t. Twelve years in, my portfolio was critically low. What went wrong wasn’t mysterious or the result of bad luck alone. It was a cascade of factors that the rule simply doesn’t account for, and a growing body of research suggests I wasn’t alone in learning this the hard way.

The better-known cousin of the 5% approach is the 4% rule, introduced in the 1990s by financial advisor Bill Bengen. It suggests withdrawing 4% of a retirement portfolio annually without running out of money for at least 30 years. It was based on historical market data and designed as a conservative, worst-case scenario.
Some retirees believe 4% is too cautious and opt for a 5% withdrawal rate instead. It can give more income in the short term but may be harder to sustain over the long haul. The 5% rate exists in a kind of gray zone: not officially endorsed by most major research bodies, but attractive enough to tempt retirees who want more freedom with their money.

Morningstar’s 2025 retirement income research suggested that 3.9% is the highest safe starting withdrawal rate for retirees seeking a consistent level of inflation-adjusted spending from year to year, assuming a 90% probability of having funds remaining at the end of an assumed 30-year retirement period. That’s meaningfully lower than 5%.
There is over 30 years of research exploring how much a retiree can withdraw annually from a portfolio upon retirement, with estimates generally ranging from 2% to 8%, and the industry largely coalescing around 4%. A full percentage point above that consensus, sustained year after year, creates compounding pressure that most retirees underestimate when they’re making the initial decision.

Experiencing a market drop in the early years of retirement can create problems that go beyond the immediate hit to your portfolio, potentially to the point where your portfolio may not last as long as you need. That could prove catastrophic if you’re just embarking on what could turn out to be a 25- or 30-year retirement.
Negative returns during the first five years account for roughly 70% of retirement plan failures, creating a compounding depletion effect that limits recovery potential even when markets eventually rebound. When you tap into your portfolio as it’s losing value, you have to sell more investments to raise a set amount of cash. Not only does that drain your savings more quickly, but it also leaves you with fewer assets that can generate growth and returns during potential future recoveries.
How Inflation Quietly Accelerated the Damage

U.S. inflation peaked at nearly 9% in June 2022, which made retirement savings and inflation major concerns for millions of Americans. For anyone already taking 5% withdrawals from their portfolio, that period was particularly damaging. The real purchasing power of each withdrawal was shrinking at the same time the portfolio itself was getting hit.
Retirees on Social Security have been losing buying power for years. Social Security benefits lost about one fifth of their buying power between 2010 and 2024, according to the non-partisan Senior Citizens League. That erosion meant my Social Security checks covered less each year, forcing me to lean harder on portfolio withdrawals than I had planned.

According to the 2025 Fidelity Retiree Health Care Cost Estimate, a 65-year-old individual may need approximately $172,500 in after-tax savings to cover health care expenses in retirement. That figure doesn’t even account for long-term care costs. I had budgeted for healthcare in a general sense, but I hadn’t anticipated just how fast those costs would compound.
Healthcare costs have been increasing at one-and-a-half to two times the rate of general inflation. A 55-year-old couple today can expect to pay more than $1 million for healthcare costs during their retirement. Healthcare is one of the most significant expenses in retirement, and costs have historically outpaced general inflation. Retirees must prepare for these increases, which can rapidly deplete savings if not planned for adequately.

Morningstar’s safe withdrawal figure assumes a 40% stock and 60% bond portfolio, a 30-year time horizon, and a 90% probability of not running out of money. On a $1 million portfolio, a 3.9% withdrawal means you get $39,000 in year one, adjusted for inflation in every subsequent year. At 5%, that same portfolio produces $50,000 in year one. The difference seems modest, but the gap widens every single year.
A $1 million portfolio would produce $37,000 in first-year withdrawals at 3.7%, compared with $40,000 under a 4% rule. For retirees living on a fixed income, $3,000 is a decent chunk of money. Missing it could certainly affect budgeting. The 5% scenario pushes that gap considerably further, and those extra withdrawals do permanent damage to compounding over time.
What "Flexible" Withdrawal Strategies Actually Mean

Morningstar tested multiple dynamic withdrawal methods against its conservative base case of fixed inflation-adjusted spending each year. Every single flexible strategy the researchers examined supported a higher starting safe withdrawal rate than the 3.9% base case. The key word is flexible: meaning you cut back when markets fall, not continue pulling the same amount regardless of conditions.
The traditional approach of withdrawing a fixed percentage each year doesn’t account for market conditions. Flexible withdrawal planning means reducing what you take in down years and increasing it in strong years. Even small adjustments, pulling 3.5% instead of 4% during a bear market, can significantly extend a portfolio’s life. I did not do this. I stayed rigid when the environment demanded adaptability.
What Bengen, the Original Rule-Maker, Says Now

The rule that says it’s generally safe to withdraw 4% of a balanced portfolio annually, adjusted for inflation, for a 30-year retirement was first described in a 1994 paper published in the Journal of Financial Planning by financial advisor Bill Bengen. Bengen has since revised his own thinking significantly.
Under the historical worst-case scenario, one with high inflation and an unfavorable stock market, an investor can safely withdraw 4.7% in retirement without running out of money for 30 years. For a 50-year retirement, it’s closer to 4.2%. Even Bengen’s updated higher figure falls short of 5%, and it comes with the assumption of a diversified portfolio including small-cap and international exposure, not a basic balanced fund.

Retirement can last 25 years or more these days, so you need a strategy that’s built for the long haul. If you increase the simulation time to more than 30 years, a 4% withdrawal rate is no longer safe. With 50 years of retirement, you have a 90% chance of success with a 4% withdrawal rate at most. A withdrawal rate of around 3.5% would be safer for most people.
In practice, the “safe” rate depends not just on market performance but also on age, health, lifestyle and willingness to adjust withdrawals as conditions change. Retiring at 62 rather than 65 added years to my horizon that the standard models don’t comfortably accommodate. Every extra year in retirement is another year demanding money from a portfolio that keeps shrinking.
What I Would Do Differently

Day-to-day, must-have expenses in retirement like housing, food, and health care are best covered by lifetime guaranteed income sources, such as Social Security, pensions, or income annuities. Building a foundation of guaranteed income before relying on portfolio withdrawals would have changed everything. It would have allowed me to take far less from my investments each year during the critical early period.
One approach is to maintain a short-term reserve of low-risk liquid investments that you can use to cover expenses while you avoid tapping your stocks. Experts suggest keeping a year’s worth of expenses after accounting for other income sources, including Social Security, in cash investments and another two to four years’ worth in high-quality short-term bonds. A cash buffer like this would have shielded my equity holdings during the worst market stretches instead of forcing me to sell at the worst possible times.
The 5% rule isn’t necessarily a trap for every retiree in every situation, but for anyone without a reliable income floor, a long retirement horizon, and the discipline to adjust spending when markets turn difficult, it carries far more risk than the clean simplicity of the number suggests. The math works beautifully on a spreadsheet. Reality tends to be less cooperative.
