Does the 4% Rule Still Work in 2026?
Quick answer: The "4% rule" comes from research by financial planner William Bengen in 1994, who studied historical U.S. market data and found that retirees could withdraw 4% of their initial portfolio in the first year of retirement, adjust for inflation each subsequent year, and have a high probability of not running out of money over a 30-year retirement. The rule remains a useful starting framework for retirement withdrawal planning — but it's a framework, not a universal answer. Its appropriateness depends on your portfolio composition, retirement length, other income sources, spending flexibility, current market valuations, and personal goals. For Columbus, Ohio retirees in 2026, the 4% rule is best used as a sanity check against a personalized withdrawal plan rather than as the final word on how much to withdraw. Several alternative frameworks have emerged since 1994 that may fit specific situations better. This article is educational; specific withdrawal advice requires a qualified financial professional.

Where the 4% Rule Came From
The 4% rule originated from a 1994 paper by William Bengen, a California-based financial planner, published in the Journal of Financial Planning. Bengen wanted to answer a practical question that his clients kept asking: how much can I withdraw from my portfolio in retirement without running out of money?
To answer that question, Bengen examined historical U.S. stock and bond market data going back to 1926. For every 30-year period in that data, he tested various initial withdrawal rates — 3%, 4%, 5%, 6%, etc. — adjusted annually for inflation, applied to a portfolio of 50-75% stocks and the remainder in bonds.
What he found: Across all the 30-year historical periods he studied, an initial withdrawal rate of 4% (adjusted for inflation each year) succeeded in supporting the full 30-year retirement in essentially every case — including the most challenging historical periods like retirements starting in 1929, 1937, or 1966.
Higher withdrawal rates had failure cases — periods where the retiree would have run out of money before 30 years. Lower withdrawal rates left meaningful unused assets but provided greater safety. The 4% figure emerged as the threshold that combined acceptable income with high historical safety.
Important context: Bengen's research was retrospective — it analyzed what would have worked in the past. It wasn't a prediction or a guarantee about future performance. It was an empirical finding about the historical relationship between withdrawal rates, market returns, and portfolio sustainability.
This article is part of my broader guide on how to plan retirement income in Columbus, Ohio, which covers how withdrawal strategy fits with the rest of the retirement income picture.
What the Original Research Actually Said
Several features of Bengen's original research are often overlooked in the simplified "4% rule" that gets passed around.
The portfolio composition mattered. Bengen's analysis used a stock-heavy portfolio — typically 50-75% stocks with the remainder in intermediate-term U.S. government bonds. Portfolios with significantly less stock exposure produced lower sustainable withdrawal rates in his research. The "4% rule" implicitly assumes a stock-heavy allocation.
The 30-year time horizon was specific. Bengen tested 30-year retirements. Shorter retirements (say, 20 years) could sustain higher withdrawal rates; longer retirements (40+ years) might require lower rates. The 4% figure isn't a universal constant — it's specifically calibrated to a 30-year period.
The inflation adjustment is annual. The rule isn't "withdraw 4% every year." It's "withdraw 4% of the initial portfolio in year one, then adjust that dollar amount for inflation each subsequent year." A retiree starting at $1 million withdraws $40,000 in year one, then approximately $41,200 in year two (assuming 3% inflation), and so on — regardless of what the portfolio is worth.
The success measure was "didn't run out." Bengen's standard was whether the portfolio supported the full 30-year retirement without depleting. He didn't measure ending wealth, only sustainability. A "successful" retirement under his definition could end with $0 or with $5 million remaining — both counted as success.
The data was U.S.-only. Bengen's analysis used U.S. stock and bond returns. International market data over the same period would have produced different results in some cases.
The historical period included some exceptional returns. The 1926-1990 period that Bengen analyzed included significant U.S. economic and market expansion. Whether future periods will produce similar returns is unknowable.
These features of the original research matter because they shape how the rule should be applied today.
Why the 4% Rule Became So Influential
The 4% rule became one of the most-cited frameworks in retirement planning for several reasons.
It provided a concrete answer. Before Bengen's research, there was no widely accepted withdrawal rate. Financial advisors and retirees were operating without a clear benchmark. The 4% figure gave the industry a starting point.
It was based on actual data. Earlier withdrawal recommendations were often based on intuition or simplified assumptions. Bengen's work used real historical returns, which gave it credibility.
It was simple enough to apply. The math is straightforward: take your portfolio value at retirement, multiply by 4%, that's your first-year withdrawal. Adjust for inflation each subsequent year. No complex modeling required.
Subsequent research generally validated the framework. While various researchers have refined and critiqued the 4% rule, the broad finding — that a 4-4.5% initial withdrawal rate, inflation-adjusted, has historically been sustainable for a 30-year retirement — has held up reasonably well.
The rule is genuinely useful as a starting point. For pre-retirees trying to figure out whether they have enough saved, the 4% rule provides a quick reality check. If you need $80,000 a year from your portfolio and you have $1 million, the 4% rule says you might be borderline. If you have $2.5 million, you're probably fine. That kind of rough orientation is genuinely valuable.
For Columbus-area pre-retirees, the 4% rule remains useful as one of several tools for thinking about whether retirement is financially feasible — and at what age.
The Limitations of a Fixed Withdrawal Rate
The 4% rule is genuinely useful, but it has several limitations that prevent it from being a universal answer.
It assumes static spending in real terms. The rule says you withdraw the same inflation-adjusted dollar amount every year, regardless of what your portfolio is doing. In a market downturn, you keep withdrawing the same real amount even as your portfolio shrinks. In a market boom, you don't capture the upside in higher spending.
In practice, most retirees don't behave this way. They cut spending in bad markets and may increase spending after good ones. A more flexible approach often produces better outcomes than the strict 4% rule's discipline of inflation-adjusted withdrawals.
It assumes a specific retirement length. The 30-year horizon works for retirees who begin retirement at 65 and live into their mid-90s. For retirees who retire earlier (at 55 or 60), the time horizon is significantly longer and the appropriate withdrawal rate may be lower. For retirees with shorter expected longevity due to health, the appropriate rate may be higher.
It assumes specific portfolio composition. The rule was built around a stock-heavy portfolio. Retirees who hold significantly more bonds, or who hold significant cash positions, won't produce the same results.
It doesn't account for Social Security or pensions. The 4% rule treats the portfolio in isolation. For retirees with significant Social Security or pension income, the portfolio is only part of the picture — and may not need to sustain 30 years of full spending on its own.
It doesn't address sequence of returns risk explicitly. The rule worked historically because Bengen's data included sequences with poor early returns. But individual retirees facing poor early-retirement returns can still see their plans damaged in ways that exceed the rule's safety margin.
Starting market valuations matter. Recent research suggests that the safe withdrawal rate is somewhat dependent on the market environment at the start of retirement. Retiring into expensive markets may require lower withdrawal rates; retiring into cheap markets allows higher rates.
It doesn't address spending flexibility. Some retirees can flex spending down 20-30% in difficult years without serious consequences. Others have largely fixed expenses with little room to cut. The 4% rule doesn't distinguish between these very different situations.
For Columbus-area retirees, these limitations mean the 4% rule is a starting framework — not a finished answer.
Alternative Withdrawal Frameworks
Several alternative withdrawal frameworks have emerged to address the 4% rule's limitations.
Dynamic withdrawal strategies. Rather than fixed inflation-adjusted withdrawals, these strategies adjust based on portfolio performance. After good years, withdrawal amounts may increase; after bad years, they may decrease. The discipline is harder for retirees to maintain emotionally, but the math often produces better outcomes than the 4% rule.
Guardrails approaches. These methods set upper and lower withdrawal "guardrails" tied to portfolio performance. When the portfolio is performing well, withdrawals can increase up to a cap. When the portfolio is struggling, withdrawals are reduced to a floor. The guardrails maintain spending flexibility while preventing both excessive depletion and unnecessary restriction.
Bucket strategies. Bucket approaches segment retirement assets by time horizon. A short-term bucket (1-3 years of spending) is held in cash or short-term bonds. A medium-term bucket (3-10 years) holds bonds or balanced investments. A long-term bucket (10+ years) holds growth-oriented investments. Withdrawals come from the short-term bucket, which is refilled from the other buckets based on market conditions. The approach addresses sequence risk and gives retirees psychological comfort with their cash reserve.
Income-based approaches. Rather than focusing on a withdrawal rate from a single portfolio, these approaches map specific spending needs to specific income sources — Social Security and pensions covering fixed expenses, portfolio income covering variable expenses, and investment growth providing inflation protection. The "rate" matters less than the matching.
Variable percentage withdrawal. Some approaches use a fixed percentage of the current portfolio value each year (instead of an inflation-adjusted dollar amount based on the initial value). This produces highly variable withdrawals that follow market performance directly. The discipline can be hard, but the portfolio never depletes mathematically — it just produces lower withdrawals in bad years.
Required Minimum Distribution-based approaches. Some retirees use the IRS's RMD table as their withdrawal guide — withdrawing each year the amount the RMD table would require. The approach automatically adjusts for age and portfolio size, producing rising withdrawal rates as the retiree ages.
Floor-and-upside strategies. These approaches use guaranteed income sources (Social Security, pensions, perhaps annuities) to cover essential spending, leaving the portfolio entirely for discretionary or growth needs. The "withdrawal rate" question becomes less important when essential needs are covered by guaranteed income.
For Columbus-area retirees, the appropriate framework depends on personal circumstances — and most retirees benefit from professional analysis of which approach (or hybrid) fits their situation.
The Sequence of Returns Wrinkle
The 4% rule's historical success rests on something important: the historical data included some terrible sequences of returns, and the rule still held up.
But sequence risk remains the underappreciated danger of any fixed-withdrawal approach. We cover sequence of returns risk in detail in our forthcoming piece on sequence of returns risk (coming soon in this series).
The core issue: A retiree withdrawing 4% inflation-adjusted from their portfolio is most vulnerable in the first 5-10 years of retirement. Poor returns during that period, combined with ongoing withdrawals, can damage the portfolio in ways that even strong subsequent returns can't fully recover.
Why the 4% rule worked historically anyway: Bengen's data included starting periods with truly difficult market conditions (the early 1930s, the late 1960s) — and the rule held up across all of them. The 4% figure was specifically calibrated to survive the worst historical sequences, not the average.
Where this creates ambiguity for current retirees: The future could produce sequences that are worse than the worst historical periods. The rule's safety margin reflects historical worst cases — not theoretical worst cases. A retiree facing an unprecedented downturn in their first decade of retirement may find that "4% safe in history" doesn't translate to "4% safe today."
The implication isn't to abandon the 4% rule or to panic about sequence risk. It's to recognize that the rule's safety margin is real but not infinite, and that planning should include some buffer for sequences that might exceed historical experience.
What's Different About 2026 Market Conditions
The retirement income planning environment in 2026 has several features that differ from when Bengen did his original research.
Higher starting bond yields than the past 15 years. After a long period of low interest rates, bond yields have risen meaningfully. This generally supports higher sustainable withdrawal rates because bonds now contribute more meaningful income to the portfolio.
Equity market valuations. U.S. equity valuations have been elevated by various historical measures for an extended period. Some research suggests that starting valuations affect subsequent returns, though the relationship is complex and unreliable for shorter time horizons.
Inflation has been more variable. The 2021-2024 period included higher inflation than the previous decade. Whether this represents a temporary deviation or a longer-term shift affects what "inflation-adjusted withdrawals" actually means.
Life expectancy has been gradually rising. Modern retirees may face longer retirements than the 30-year horizon Bengen tested. This pushes toward more conservative withdrawal rates.
More diversification options exist. The investment landscape now includes options Bengen's research didn't reflect — international markets, alternative assets, more sophisticated bond strategies, retirement-specific annuities. These can affect portfolio sustainability.
Healthcare costs have grown faster than general inflation. A retirement income plan that allowed for general inflation may still face shortfalls if healthcare costs (a significant retirement expense) inflate faster.
The implication for 2026 retirees: The 4% rule may remain a useful starting framework, but it should be applied with awareness of the current environment — not as a static formula from 30 years of research that predated current conditions.
How to Use the 4% Rule Today
For Columbus-area retirees and pre-retirees, the 4% rule can still be useful — when applied thoughtfully.
Use it as a sanity check. If your retirement income need is $80,000/year from your portfolio (after Social Security), the 4% rule suggests you should have $2 million in invested assets. That gives you a quick reality check on whether retirement is feasible at current savings levels.
Use it as a starting point for deeper planning. A 4% withdrawal rate isn't the answer for any specific retiree — but it's a reasonable starting point that can be refined based on your circumstances. From there, factors like portfolio composition, time horizon, other income, and flexibility shape the actual right rate.
Don't apply it rigidly. If your portfolio is performing well, you don't have to constrain yourself to inflation-adjusted withdrawals. If it's struggling, you may need to cut below the rule's discipline. The rule's value is in providing a framework, not in commanding strict adherence.
Pair it with sequence risk awareness. The 4% rule worked historically partly because retirees who faced bad sequences happened to also have other resources or flexibility. A modern retiree should explicitly consider what they'd do in a worst-case sequence — and that planning should inform the withdrawal strategy.
Update it as conditions change. A withdrawal rate that made sense at 65 may need adjustment at 75. Market conditions, health, family circumstances, and goals all change. The withdrawal strategy should evolve with them.
Coordinate with other income sources. The 4% rule treats the portfolio in isolation. In reality, Social Security claiming timing, pension income, and other resources affect how much the portfolio actually needs to provide. Coordinating these is part of comprehensive retirement income planning.
For Columbus-area retirees, the most useful application of the 4% rule is as one tool among several — not as the final answer to "how much can I withdraw?"
Common Misconceptions
Several misconceptions about the 4% rule come up regularly.
"The 4% rule means I withdraw 4% every year." No. The rule is to withdraw 4% of the initial portfolio in year one, then adjust that dollar amount for inflation each subsequent year. After several years, the actual withdrawal might be 3.5% of current portfolio value (if the portfolio grew) or 5% (if it shrank).
"The rule guarantees I won't run out of money." No. The rule has worked historically in essentially all 30-year periods Bengen tested, but it's not a guarantee. Future conditions could differ from historical experience.
"4% is the right rate for everyone." No. The 4% figure was calibrated to a specific portfolio, time horizon, and goal (not running out over 30 years). Different circumstances may warrant higher or lower rates.
"The rule means I should keep withdrawing the same amount no matter what." No. The rule describes a withdrawal pattern, not a commandment. Most retirees benefit from at least some flexibility — increasing withdrawals after good years, reducing after bad ones.
"The 4% rule applies to my entire net worth." No. The rule applies to invested portfolio assets, not to your home equity, business interests, or other illiquid wealth. Treating the home as part of the "4% portfolio" produces misleading results.
"The 4% rule worked historically so it will work going forward." Maybe — but this isn't certain. The rule's historical performance reflects U.S. market history, which may or may not predict future performance. Building some safety margin is prudent.
"If I withdraw less than 4%, I'll definitely be fine." Not necessarily. Lower withdrawal rates increase safety margin, but extreme sequences could still produce difficulties. Lower rates also mean leaving more potential spending unused — which has its own costs.
Frequently Asked Questions
What is the 4% rule? The 4% rule is a retirement withdrawal framework developed by financial planner William Bengen in 1994. It suggests withdrawing 4% of your initial portfolio in the first year of retirement, then adjusting that dollar amount for inflation each subsequent year. Bengen's historical research found this approach succeeded in supporting 30-year retirements across all tested historical periods.
Is the 4% rule still safe in 2026? The 4% rule remains a useful starting framework but should not be treated as a universal answer. Market conditions, retirement length, portfolio composition, and individual circumstances all affect whether 4% is appropriate for any specific retiree. Many retirees benefit from using the rule as a sanity check rather than as a finished answer.
Where did the 4% rule come from? The rule comes from research by financial planner William Bengen published in the Journal of Financial Planning in 1994. Bengen analyzed historical U.S. stock and bond returns to identify the maximum withdrawal rate that would have supported a 30-year retirement across all historical periods.
Does the 4% rule include Social Security? No. The 4% rule applies to portfolio withdrawals only. For retirees with Social Security or pension income, the portfolio is only part of the retirement income picture. Social Security and pension income reduce how much the portfolio needs to provide.
What if I withdraw more than 4%? Withdrawal rates higher than 4% increase the risk of running out of money before 30 years are up, particularly if poor market performance occurs early in retirement. Some retirees can sustain higher rates depending on circumstances, but the safety margin is smaller. Professional analysis is particularly valuable for retirees considering higher withdrawal rates.
Is there a better withdrawal strategy than the 4% rule? Several alternatives have emerged — dynamic withdrawals, guardrails approaches, bucket strategies, variable percentage withdrawals, RMD-based approaches, and floor-and-upside strategies. None is universally better than the 4% rule; the best approach depends on individual circumstances and preferences.
Should I withdraw 4% from my IRA, my 401(k), or my whole portfolio? The 4% rule applies to your total invested portfolio across all account types. The withdrawal source (which specific account to draw from) is a separate decision driven by tax efficiency, RMD requirements, and other factors. The 4% figure refers to the total amount withdrawn from the combined portfolio.
What if my portfolio is mostly in bonds? The 4% rule assumes a stock-heavy portfolio (typically 50-75% stocks). Portfolios with significantly more bonds may produce lower sustainable withdrawal rates. The 4% figure is calibrated to a specific portfolio composition.
How long is the retirement period in the 4% rule? The rule is calibrated to 30 years. For longer retirements (early retirees), a lower rate may be appropriate. For shorter retirements, higher rates may be sustainable. The 30-year horizon is the standard but not a universal truth.
Should I work with a financial advisor on withdrawal strategy? Most retirees with meaningful retirement assets benefit from professional analysis of withdrawal strategy. The interactions between withdrawal rates, Social Security claiming, tax efficiency, sequence risk, and individual circumstances are complex enough that a coordinated plan typically produces better outcomes than rule-of-thumb application.
The 4% Rule Is a Starting Point, Not the Final Word
For Columbus-area retirees and pre-retirees, the 4% rule remains a genuinely useful framework — particularly as a quick way to think about whether retirement is financially feasible. But it's a framework, not a finished answer. The actual right withdrawal rate for your situation depends on factors the rule doesn't capture: portfolio composition, retirement length, other income, spending flexibility, market starting conditions, and personal goals.
The pattern that produces better outcomes: use the 4% rule as one input alongside personalized planning, alternative frameworks where they fit better, and ongoing review as circumstances change. Treat the rule as the start of the analysis, not the end of it.
