For years, retirees have been told that withdrawing 4% of their savings each year is the safest way to make their money last. But retirement rarely follows a predictable path, especially when inflation, market losses, and unexpected expenses arrive together.
A strategy that looks comfortable at 65 can feel very different at 75. Some retirees worry about running out of savings, while others discover they have been unnecessarily restricting their spending.
New retirement research is changing how financial planners approach this familiar rule. Instead of relying on one percentage for life, they are finding ways to balance financial security with the freedom to actually enjoy retirement.
The 4% Rule Was Never Meant to Be a Perfect Retirement Formula
The 4% rule became widely known after financial planner William Bengen published research in 1994. He examined historical stock and bond returns to estimate how much retirees could withdraw without exhausting their savings over a 30-year period.
His original research identified an initial withdrawal rate of about 4.15% that survived the historical periods he tested. Over time, the finding became widely known as the simpler 4% rule.
Under the traditional approach, a retiree withdraws 4% of the portfolio’s starting value in the first year. In later years, the retiree adjusts that original dollar amount for inflation rather than taking 4% of the changing account balance.
Consider someone retiring with $1 million in investments.
- First year: Withdraw $40,000.
- Second year: If inflation is 3%, withdraw $41,200.
- Third year: Adjust the $41,200 withdrawal using the next year’s inflation rate.
The goal is to provide a reasonably steady amount of purchasing power throughout retirement. The rule was based on historical investment outcomes, not a guarantee of future market performance.
Bengen has continued expanding his research. His updated historical work now discusses a 4.7% withdrawal rate, showing that even the original researcher does not consider 4% a universal limit.
However, higher historical withdrawal rates do not mean every retiree can safely spend more. Portfolio composition, investment costs, retirement length, and future returns all affect the outcome.
Why Retirement Experts Are Questioning the Same Old Number
One reason the 4% rule is getting another look is that retirement researchers do not all arrive at the same answer.
In its December 2025 retirement income research, Morningstar estimated a 3.9% safe starting withdrawal rate for a new retiree seeking steady inflation-adjusted withdrawals over 30 years.
That estimate assumed a 90% probability of having money remaining at the end of the period. It was based on projected investment returns and inflation rather than simply repeating past market performance.
Other researchers use different methods and assumptions, producing different results.
| Research or Guidance | Withdrawal Figure | What It Represents |
|---|---|---|
| Bengen’s original 1994 research | About 4.15% | Historical 30-year survival threshold |
| Bengen’s expanded research | 4.7% | Updated historical withdrawal analysis |
| Morningstar’s 2025 research | 3.9% | Projected 30-year starting rate with 90% success probability |
| Fidelity’s 2026 general guidance | 4% to 5% | Broad initial withdrawal planning range |
These figures are not directly interchangeable. Each depends on assumptions about investment returns, time horizons, portfolio allocations, and acceptable risks.
The larger change is not that everyone should replace 4% with 3.9% or 4.7%. It is that retirees increasingly need a withdrawal strategy designed for their own financial circumstances.
A homeowner with a substantial pension faces different risks from someone who depends almost entirely on an IRA. Both might have $700,000 invested, but that does not mean both should follow the same spending plan.
1. Retirees Are Moving Away From Fixed Withdrawals Every Year
One major change is the growing interest in flexible withdrawals. Instead of automatically increasing spending every year, retirees can adjust their withdrawals when their investments perform especially well or poorly.
The traditional rule does not respond directly to stock market losses. Even after a difficult investment year, it calls for another inflation adjustment to the previous withdrawal amount.
That can create pressure during the early years of retirement.
Imagine a retiree begins with $800,000 and plans to withdraw $32,000 annually. If the portfolio falls to $640,000 before a withdrawal, the original $32,000 now represents 5% of the reduced portfolio.
Continuing to increase withdrawals during a prolonged downturn could make recovery more difficult.
A flexible approach might involve delaying a large vacation, reducing entertainment expenses temporarily, or skipping an annual inflation increase. Those adjustments leave additional money invested when the portfolio is under pressure.
Four Withdrawal Methods Retirees Are Comparing
| Withdrawal Strategy | How It Works | Main Trade-Off |
|---|---|---|
| Traditional 4% rule | Starts with 4%, then adjusts the dollar amount for inflation | Stable spending but limited response to losses |
| Fixed portfolio percentage | Withdraws a set percentage of the current balance annually | Spending can fall sharply in weak markets |
| Guardrails strategy | Raises or lowers spending when preset limits are reached | Requires regular reviews and occasional cuts |
| Dynamic spending with a floor and ceiling | Adjusts spending within a planned range | Offers some stability but does not eliminate risk |
Vanguard describes dynamic spending as a method that combines features of fixed-dollar withdrawals and percentage-based spending. It sets boundaries to prevent annual withdrawal changes from becoming too large.
Morningstar’s research also found that flexible methods can support higher starting withdrawals under certain conditions. However, the benefit comes with a trade-off: retirees must accept more variation in their income.
That means a flexible strategy may suit someone who can reduce travel or leisure spending. It may be much harder for a retiree whose portfolio withdrawals are already needed to pay rent, utilities, and medical bills.
2. The First Five Years of Retirement Are Getting More Attention
Many retirees focus on average investment returns. Yet the order in which those returns arrive can be just as important.
This is known as sequence-of-returns risk. It becomes especially concerning when a market downturn occurs near the beginning of retirement, while withdrawals are already reducing the portfolio.
Consider two retirees who experience similar long-term investment returns. One enjoys strong markets during the first five years, while the other experiences substantial early losses.
The second retiree may have to sell more investments at depressed prices to cover living expenses. Those investments are no longer available to benefit fully when markets recover.
Morningstar’s 2025 research identified weak investment returns during the first five retirement years as a major threat to portfolio survival, particularly when spending remains unchanged.
That does not mean retirees must avoid stocks. It means they need a plan for withdrawals when markets are falling.
Some people maintain cash reserves or high-quality short-term bonds to cover near-term spending. Others use a flexible spending plan that reduces withdrawals when portfolio values decline.
Neither method removes investment risk completely. Holding too much cash can also reduce long-term growth and expose purchasing power to inflation.
The aim is to avoid being forced into poor financial decisions during a difficult market.
3. More Retirees Are Separating Essential Spending From Lifestyle Spending
One of the most useful changes is dividing retirement expenses into two groups. The first covers bills that must be paid, while the second covers activities that can be adjusted.
Essential spending generally includes housing, groceries, insurance, transportation, utilities, and routine health care.
Flexible spending might include vacations, restaurants, gifts, hobbies, or home upgrades that can be postponed without affecting basic safety.
This distinction matters because a retiree with dependable income covering most essential expenses may be able to adjust investment withdrawals more easily.
Example: A Retirement Budget Built Around Reliable Income
| Budget Category | Annual Amount |
|---|---|
| Housing, food, insurance, health care, and other essentials | $40,000 |
| Travel, entertainment, gifts, and flexible expenses | $18,000 |
| Total planned annual spending | $58,000 |
| Social Security income | $30,000 |
| Pension income | $12,000 |
| Amount needed from investments | $16,000 |
Illustrative amounts before any additional taxes. Actual household spending and income will vary.
In this example, Social Security and the pension provide $42,000 annually. That covers the $40,000 essential budget before considering taxes or unusual expenses.
The retiree only needs $16,000 from investments to support the planned $58,000 lifestyle. If the investment portfolio is worth $600,000, that represents a starting withdrawal rate of about 2.7%.
This is a different situation from someone with the same savings but no pension and much higher fixed expenses.
The key question becomes how much of the household budget depends on investments, not simply how large the investment portfolio is.
It is also worth checking whether pension income has inflation protection. A pension that never increases may cover less of the household budget as prices rise.
4. Inflation Is Changing How Retirees Think About Annual Raises
The traditional 4% rule assumes retirees increase their withdrawal amounts to keep pace with inflation. That sounds reasonable because groceries, utilities, insurance, and medical expenses can become more expensive over time.
The problem is that inflation does not affect every household equally. A retiree with a paid-off home may experience different spending pressures from someone facing annual rent increases.
Some expenses may also decline. A retiree might travel less at 82 than at 67, while spending more on home assistance or medical care.
This makes automatic annual increases less useful as a complete retirement budget strategy.
One alternative is to review actual household costs before deciding how much of an inflation adjustment is necessary. Another is to skip an increase following a negative investment year, provided essential living costs remain covered.
Morningstar has examined strategies that suspend inflation adjustments after portfolio losses. Its findings suggest that these approaches can improve withdrawal flexibility without the large income swings associated with some other methods.
Still, consistently skipping inflation adjustments can create problems. Over many years, even modest price increases reduce purchasing power.
Retirees therefore need to distinguish between spending they can control and costs they cannot reasonably avoid.
5. Retirement Age Is Becoming More Important Than the Percentage
The 4% rule is commonly associated with a 30-year retirement. But retirement does not last exactly 30 years for everyone.
Someone leaving work at 55 could need savings to provide income for 40 years or more. A person retiring at 73 may have a shorter expected planning period, although their financial plan still needs to consider longevity and a surviving spouse.
Morningstar’s 2026 retirement research explains that longer planning periods generally require lower starting withdrawals when other assumptions remain the same.
The reason is straightforward. Money must cover additional years of spending, inflation, and market uncertainty.
How Retirement Timing Changes the Planning Question
| Retirement Age | Planning Concern | Withdrawal Consideration |
|---|---|---|
| 55 | Savings may need to last 40 years or longer | A lower starting rate or flexible strategy may be appropriate |
| 62 | Early Social Security claiming can affect lifetime income | Compare claiming choices and portfolio withdrawals together |
| 67 | A 30-year horizon reaches age 97 | The traditional rule can serve as a starting reference |
| 72 | Remaining years and survivor needs vary | Review the actual horizon rather than automatically restarting a 30-year plan |
| 80 | Health, care costs, and legacy goals may become more prominent | Reassess remaining spending needs and financial resources |
These are planning considerations, not withdrawal-rate recommendations for specific ages.
Older retirees should not automatically restart the 4% calculation using their current balance. Doing so can produce very different spending results from continuing an established plan.
The better approach is to review remaining assets, expected expenses, available income, and the length of time those assets may still be needed.
For married couples, the younger spouse’s life expectancy may be especially important. A portfolio that appears sufficient for one retiree could face many more years of withdrawals after the first spouse dies.
6. Social Security Is Becoming Part of the Withdrawal Decision
Another shift is treating Social Security and investment withdrawals as parts of one retirement income strategy.
Some retirees claim Social Security immediately because they want to avoid taking money from investments. Others use some savings first, allowing their future monthly Social Security benefit to increase.
For people born in 1943 or later, Social Security delayed retirement credits generally increase retirement benefits by 8% per year after full retirement age, up to age 70.
That increase applies to the benefit amount, not the retiree’s investment portfolio. It also does not mean delaying is automatically the best choice.
A person with poor health, limited savings, or a strong need for income today may have good reasons to claim earlier.
But for retirees expecting long lives, delaying can create a larger inflation-adjusted income stream later. Depending on individual circumstances, that may reduce future pressure on investment withdrawals.
Morningstar’s retirement income research found that stronger dependable income can work particularly well alongside flexible portfolio withdrawals.
The decision also matters for married couples because a higher benefit for the larger earner may improve the survivor benefit available after one spouse dies.
Retirees should compare lifetime income, taxes, survivor benefits, and the cost of using investments during any claiming delay before making a decision.
7. Taxes Are Becoming Part of the Withdrawal Calculation
The 4% rule describes how much money to remove from investments. It does not necessarily describe how much spending money remains after taxes.
A retiree withdrawing $40,000 from a traditional IRA may owe income tax on much of that distribution. Someone withdrawing money from a taxable brokerage account may face a different tax result.
Qualified Roth IRA withdrawals may be tax-free, provided the applicable requirements are satisfied.
Those differences affect how much needs to leave an account to support the same household spending.
Retirees are increasingly considering which accounts to withdraw from, not only how much to withdraw overall.
A carefully planned combination of traditional IRA distributions, brokerage withdrawals, and qualified Roth withdrawals may help control taxable income in certain years.
Taxes can also affect Social Security benefits and Medicare premiums. Larger taxable distributions can sometimes create additional costs beyond the immediate income tax bill.
Required Minimum Distributions Add Another Consideration
The IRS generally requires traditional IRA owners to begin required minimum distributions, or RMDs, under age-based rules. For many retirees currently entering that stage, the starting age is 73, while later birth cohorts may have different starting ages under current law.
An RMD does not automatically mean the entire amount must be spent. A retiree can use the distribution for living expenses and reinvest money that is not needed, subject to taxes and account rules.
The important point is to include required distributions in the overall withdrawal plan. Counting them as additional spending on top of planned withdrawals could lead to unnecessary portfolio depletion.
Tax laws, account rules, and Medicare income thresholds can change, making periodic reviews particularly useful.
8. The New Goal Is Not Always to Spend as Little as Possible
One overlooked criticism of the 4% rule is that it can encourage excessive caution.
A retiree might enter retirement with a healthy investment balance and continue restricting travel, hobbies, and family experiences out of fear that the money will disappear.
In many favorable market scenarios, conservative withdrawal strategies leave substantial assets unspent. This can be a welcome result for someone who wants to leave a large inheritance.
But it may be less desirable for someone whose main goal is to use retirement savings to support a comfortable life.
Research from Morningstar has highlighted this tension between lifetime spending and the amount left for heirs. Flexible withdrawal methods often increase spending opportunities but can reduce final portfolio balances.
That is not automatically a bad outcome. It depends on what the retiree wants the money to accomplish.
A person hoping to help grandchildren with education expenses may prefer protecting more assets. Another retiree may place greater value on traveling while physically able.
Both goals can be reasonable.
The problem comes when a withdrawal rule makes those choices automatically, without considering what matters most to the household.
9. Annual Reviews Are Replacing the Set-It-and-Forget-It Approach
The strongest retirement spending plan is not necessarily the one with the most calculations. It is the one the retiree understands, follows, and can adjust when circumstances change.
A yearly review can help identify whether spending remains appropriate. It can also reveal when the portfolio is growing faster than expected or when withdrawals are becoming too large.
Charles Schwab’s 2026 retirement guidance encourages retirees to personalize their withdrawal rates and review their plans regularly rather than following the 4% rule without adjustment.
A Practical Annual Retirement Withdrawal Review
| What to Check | Question to Ask | Possible Response |
|---|---|---|
| Portfolio value | Has the balance changed significantly? | Recalculate the current withdrawal percentage |
| Inflation | Which household costs have actually increased? | Adjust the budget based on real needs |
| Guaranteed income | Have Social Security or pension payments changed? | Update the amount needed from savings |
| Taxes | Could withdrawals create avoidable tax costs? | Review account choices and distribution timing |
| Health and housing | Are new expenses becoming likely? | Update cash reserves and future spending assumptions |
| Personal goals | Are meaningful experiences being delayed unnecessarily? | Review whether additional spending is affordable |
A particularly helpful calculation is the current withdrawal percentage.
Divide the planned annual portfolio withdrawal by the current portfolio value. Compare that figure with the household’s long-term plan and the range of spending changes it can tolerate.
For example, withdrawing $30,000 from a portfolio now worth $600,000 represents 5% of current assets. That does not automatically mean the plan will fail, but it deserves closer examination if the original strategy assumed much lower withdrawals.
This review should also consider the next several years rather than only the next 12 months.
Large home repairs, planned vehicle purchases, helping relatives, and possible care expenses can all change how much should remain available.
What Retirees Should Consider Before Changing Their Withdrawal Rate
Switching from a fixed 4% rule to a flexible approach can sound appealing. However, a spending plan must still work when investment markets perform poorly.
A retiree considering a higher starting withdrawal rate should ask how much spending could realistically be reduced during difficult years.
Someone with substantial discretionary spending may have more flexibility. Someone whose withdrawals mainly cover housing, food, and health care may need a more conservative approach.
There is also a difference between an initial withdrawal rate and a guaranteed lifetime income stream. A projected 90% probability of success still leaves a meaningful possibility that the portfolio may be depleted under the modeled conditions.
Before making major changes, it helps to review the retirement plan under several conditions: weaker returns, higher inflation, increased medical expenses, and a longer life than expected.
A qualified financial planner can help test those possibilities and consider the tax consequences of different withdrawal methods.
The purpose is not to find the highest possible percentage. It is to create a spending plan that remains workable across a wide range of outcomes.
So, Is the 4% Rule Still Useful in 2026?
The 4% rule has not become useless. It remains a simple starting point for understanding how a retirement portfolio might support annual spending.
For someone with $750,000 invested, a 4% first-year withdrawal equals $30,000. That calculation can help establish an initial budget and show how much additional income may be needed.
But the calculation cannot determine whether the household will remain financially comfortable for the next 25 or 35 years.
It does not know when markets will fall, how inflation will affect the retiree’s actual costs, or whether housing and health needs will change.
That is why recent research places more emphasis on flexible withdrawals, dependable income, spending priorities, and regular reviews.
The real change this decade is the move away from treating retirement spending as a single percentage that never needs reconsideration.
A good withdrawal plan should protect retirees from running out of money without automatically preventing them from using the savings they worked decades to build.
For many households, the strongest approach may begin with the 4% rule, then adjust to reflect age, income, taxes, investment performance, and personal goals.
Retirement savings are meant to provide both security and opportunity. A withdrawal plan works best when it respects both.
