Safe Withdrawal Rate By Age: How to Calculate

Planning how much to withdraw in retirement often starts with understanding the safe withdrawal rate by age. This concept helps retirees estimate how much they can spend each year without running out of money over time. While a 4% withdrawal rate has been a common benchmark, actual safe rates can vary depending on a retiree’s age, market conditions and life expectancy. Adjusting withdrawal strategies based on age can create more flexibility and help manage risks like inflation and longevity.

What Is a Safe Withdrawal Rate?

A safe withdrawal rate refers to the percentage of a retirement portfolio that can be withdrawn each year without significantly increasing the risk of depleting assets too early. It serves as a guideline for balancing spending needs with the goal of preserving capital over an unknown retirement length. Rather than offering a fixed number, the safe withdrawal rate reflects the relationship between market returns, inflation, life expectancy and personal risk tolerance.

The “4% rule” has long been used as a way to calibrate withdrawal strategies. This benchmark emerged from research examining actual portfolio performance under historical circumstances. Findings suggest that withdrawing 4% of an initial retirement portfolio and adjusting this amount annually for inflation will allow savings to last at least 30 years in all historical periods.

Traditional vs. Updated Safe Withdrawal Rates

While the 4% rule became a cornerstone of retirement planning, its creator, William Bengen, has since updated his guidance. In his 2025 book “A Richer Retirement: Supercharging the 4% Rule to Spend More and Enjoy More,” Bengen argues that retirees can actually withdraw at least 4.7% in their first year of retirement without undue risk. He has even suggested that under current conditions, many retirees may sustain withdrawal rates as high as 5.25% to 5.5%.¹

These new figures reflect changes in market assumptions and improved modeling of retirement outcomes. At the same time, many retirement planners continue to recommend more conservative rates, often between 3% and 4%, especially for younger retirees with longer time horizons. 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.

Safe Withdrawal Rates By Age

Age has a direct influence on how much a retiree can safely withdraw each year. The earlier retirement begins, the longer the savings need to last, often leading to more conservative withdrawal strategies. In contrast, starting retirement later in life typically allows for higher withdrawal rates. That is because the portfolio does not need to support as many years of spending.

Early Retirement (Ages 50-60)

Retiring in your 50s usually calls for a more conservative withdrawal approach. At that age, retirement can last 35 years or longer. Over that span, even modest overspending early on can dramatically increase the risk of running out of money. As a result, many financial models suggest early retirees start with a withdrawal rate closer to 3%. Bear in mind that withdrawing any amount from a tax-deferred account like a 401(k) or traditional IRA before age 59 ½ will typically trigger a 10% early withdrawal penalty.

A lower withdrawal rate places more emphasis on cost containment. For example, if you retire at 55 with $3 million, a 3% withdrawal rate would generate $90,000 in the first year before any penalty. While $90,000 offers a substantial annual income, it still requires careful budgeting, particularly with the likelihood of rising healthcare costs and potential market volatility.

Retirees in this age group often delay major discretionary spending, seek part-time income or use taxable accounts to limit early withdrawals. Building in flexibility—such as adjusting withdrawals downward during market downturns—can help stretch the portfolio’s life.

Traditional Retirement Age (Ages 60-70)

Retiring between ages 60 and 70 generally offers more flexibility. Conservative planning models often suggest a 3.5% to 4% withdrawal rate, though Bengen’s 2025 research indicates retirees in this age range could begin at closer to 4.7% or higher.

Imagine you retire at 62 with a $2 million portfolio and expect Social Security benefits of $30,000 per year starting at 67. Before claiming Social Security, you might withdraw approximately $94,000 per year using a 4.7% rate. Once Social Security kicks in, you might slightly reduce portfolio withdrawals to extend the life of your investments.

Some retirees taper down withdrawals later in life, reflecting the tendency for discretionary spending to decline with age. Others may adopt a more flexible plan that allows higher withdrawals during strong market years and lower ones during downturns.

Late Retirement (Ages 70+)

Those retiring after age 70 often adopt higher initial withdrawal rates since the retirement horizon is shorter and guaranteed income sources such as Social Security or pensions play a larger role. While conservative models place this range between 4.5% and 5%, Bengen has suggested that today’s retirees could potentially withdraw up to 5.5% without undue risk.

Suppose you retire at 73 with $800,000 in retirement savings. A 5% withdrawal rate would offer $40,000 in the first year, supplemented by Social Security payments that you began collecting at age 70.

Required minimum distributions (RMDs) also start at 73 (75 for people born in 1960 or later). Reflecting this, withdrawal strategies at this stage often shift from asset preservation to asset decumulation. Many retirees at this age prioritize enjoying their wealth rather than focusing on portfolio longevity.

Adjusting for Health, Market Conditions and Spending Needs

While age is a major factor, personal circumstances also matter. Health, lifestyle choices and economic developments can warrant more conservative or more aggressive withdrawal adjustments.

Retirees in excellent health may still prefer a lower withdrawal rate at 70, anticipating the need for funds well into their 90s. Conversely, someone with significant health challenges may prefer a higher rate, focusing on maximizing quality of life.

Market downturns can also influence withdrawal strategies. Some retirees adopt flexible withdrawal rules, such as reducing withdrawals after poor market years, to help portfolios recover. Adjusting withdrawals based on actual conditions rather than following a fixed percentage may be preferable. This approach means retirees can better align their spending with reality as they age.

Alternative Strategies

Several alternative approaches to managing retirement withdrawals offer more flexibility than using a static safe withdrawal rate by age.

Dynamic Withdrawals

One method is dynamic withdrawals, where retirees adjust spending annually based on portfolio performance. In strong market years, they withdraw more. In downturns, they reduce spending to protect the portfolio.

Guardrails Approach

Another strategy is the guardrails approach, which sets upper and lower portfolio limits to trigger withdrawal adjustments. If the portfolio grows significantly, retirees can safely spend more. If it falls below a threshold, they tighten withdrawals.

Bucket Strategy

The bucket strategy divides assets into segments based on time horizons. Short-term needs are held in cash or bonds, while long-term growth investments remain in stocks. This helps manage risk during market volatility without forcing large portfolio sales at inopportune times.

Annuitization

Some retirees purchase immediate or deferred income annuities to secure guaranteed income and reduce portfolio withdrawals. Converting a portion of assets into predictable monthly payments lets retirees create a baseline of income to cover non-discretionary expenses.

Bottom Line

Retirement withdrawals may be approached in different ways depending on when retirement begins, how long assets need to last and personal spending needs. Age often shapes the starting point for withdrawal rates, but strategies can evolve over time to reflect changes in health, market conditions and lifestyle. Fixed rates, dynamic adjustments, bucket strategies and annuitization all offer ways to manage income sustainably. Building flexibility into a withdrawal plan can help retirees adapt over time rather than relying on a single formula.
