What Are Safe Retirement Withdrawal Rates?

Understanding safe retirement withdrawal rates is a key component of retirement planning. As you age, you will transition from accumulating wealth to drawing from your savings. It is critical to determine how much you can safely withdraw each year without depleting your nest egg. This safe withdrawal rate helps ensure that your retirement funds last throughout your golden years. Traditionally, financial experts suggest a 4% withdrawal rate as a rule of thumb. However, this can vary according to factors like market conditions, life expectancy and individual financial goals.

A financial advisor can help you determine how much you can afford to withdraw each year.

What Is a Safe Withdrawal Rate for Retirement?

Striking a balance between your savings and spending can feel like a tightrope walk in retirement. However, a safe withdrawal rate can help preserve your savings while maintaining a comfortable lifestyle.

Investment diversification can play a key role here, spreading risk and enhancing the likelihood of consistent returns. However, it’s not just a set-it-and-forget-it strategy. As a retiree, you will need to recalibrate your withdrawal rate to reflect current market trends and personal circumstances.

How much a retiree can safely withdraw from their assets each year depends on factors such as these.

Factors that Determine Your Rate

Time horizon. Your time horizon is the number of years you expect to live and take withdrawals. Typically, the shorter the time horizon, the higher the safe withdrawal rate can be.
Asset allocation. Your asset allocation is the percentage of a portfolio’s assets invested in equities, fixed-income securities and cash. Too high of an equity allocation can expose you to sequence risk. This refers to how the timing of withdrawals could damage the overall return of a retirement portfolio. Too low of an equity exposure can mean a lower long-term rate of return to sustain higher withdrawals going forward.
Market returns. Market returns reflect how a portfolio performs over a given time horizon. This will have a significant impact on the retiree’s safe withdrawal rate. If the market outperforms projections, the retiree may increase their withdrawal rate and withdraw more money than planned each year. Of course, the opposite may be true as well.
Inflation. Inflation, or the rising cost of goods and services, will also impact safe withdrawal rates. If inflation is higher than projected, the retiree may need to withdraw more money to meet their spending needs. However, this may deplete their portfolio faster and increase their longevity risk.

Understanding the 4% Rule

Formulated by William Bengen in 1994,¹ the 4% Rule emerged in the wake of the Black Monday crash of 1987. It became a guiding light for retirees navigating a nationwide shift from defined-benefit to defined-contribution plans.

It recommends that retirees withdraw 4% of their portfolio within the first year of retirement. They then adjust subsequent withdrawals for inflation. This ensures the funds remain sustainable over 30 years.

Bengen’s model, which serves as the foundation, initially assumes a balanced portfolio: 50% equities and 50% fixed-income assets. His research showed that results remained relatively consistent with an equity allocation as high as 75%, but allocations outside the 50% to 75% range could raise concerns.

Consider, for example, a retiree who has diligently saved for their golden years. Upon retiring, they calculate 4% of their $500,000 nest egg, which amounts to $20,000. This is their first year’s withdrawal.

As inflation rises by 2%, they increase their withdrawal amount to $20,400. This preserves their purchasing power while maintaining their lifestyle. By following this pattern each year, they stand a reasonable chance of extending their savings across three decades.

Limitations of the 4% Rule

Despite its popularity, the rule is not immune to criticism, particularly regarding its reliance on historical market returns. It may not predict future performance with certainty. What worked under past market conditions may not hold up in the future, making the rule somewhat risky for future retirees.

Beyond its dependence on historical returns, the 4% Rule has other limitations, primarily its rigidity. This rule of thumb assumes a consistent 30-year retirement period. It does not account for changes in personal spending over time. A retiree’s spending habits or income needs may change during a 30-year retirement.

Research suggests that typical retirement spending often follows the retirement spending smile. It starts at one level and dips in the middle of retirement. It then rises again toward the end of a person’s life, as they presumably spend more on healthcare or long-term care.

Longevity risk is another potential reason that more dynamic or conservative income planning is needed. As people live longer, there’s an increased chance of outliving the 30-year benchmark set by the rule.

Alternatives to the 4% Rule for Safe Withdrawals

The guardrail approach is a retirement withdrawal strategy that can be an alternative to the 4% rule.

These common alternatives may help you navigate the complexities of retirement planning, especially during uncertain times.

Guardrails Approach

The guardrails, or floor-to-ceiling, approach represents a flexible and responsive method that adapts to your fluctuating investment portfolio.

This retirement strategy involves setting an initial withdrawal rate based on your risk tolerance. You then adjust it within certain boundaries, or guardrails, based on your portfolio’s performance. It’s a strategy that acknowledges the unpredictable twists and turns of the financial markets.

For example, during periods of strong investment returns, retirees may increase their withdrawals to enjoy a higher standard of living. Conversely, during market downturns or economic uncertainty, they may reduce their withdrawals to preserve their savings. This will help avoid outliving their assets.

One key aspect of the guardrails approach is dynamic spending. Rather than using a rigid withdrawal rate, retirees can adjust their spending based on investment performance, inflation and longevity.

To employ this method effectively, you’ll need to establish a comfortable withdrawal rate. Then, define the guardrail limits that will trigger adjustments to this rate.

Let’s say you start with a 4% withdrawal rate, with guardrails set at 5% and 3%. Should your portfolio grow, you might increase your withdrawals up to the 5% limit. However, if it shrinks, you decrease them to protect your capital.

TIPS Ladder

Inflation can silently erode the value of your retirement savings, but Treasury Inflation-Protected Securities (TIPS) offer a safeguard. These securities are specifically designed to grow with inflation.

Unlike traditional bonds, whose fixed interest payments lose purchasing power with inflation, the principal value of TIPS adjusts with changes in the Consumer Price Index (CPI). This means that as the cost of living rises, so too does the value of the TIPS investment. This helps preserve the purchasing power of the investor’s capital.

Imagine building a ladder with rungs of different heights, each representing a TIPS with a separate maturity date. This setup can provide you with a steady flow of inflation-adjusted income that aligns with your estimated retirement expenses. A TIPS ladder can help retirees spread their exposure to interest rate and inflation risk. Meanwhile they still maintain liquidity and potentially achieve higher overall returns.

RMD Approach

It’s important to approach this strategy with caution. Recognize that while TIPS protect against inflation, they are not a cure-all. They have their own limitations, such as interest rate risk and lower yields, when compared with non-inflation-protected securities.

Some retirees may choose to simply align their annual withdrawal rate with their required minimum distributions (RMDs). A requirement of the IRS, these withdrawals currently start at age 73, or 75 if born in 1960 or later. They apply to several types of tax-deferred retirement accounts, including traditional IRAs, 401(k)s and 403(b)s. Roth IRAs and designated Roth accounts within retirement plans do not require withdrawals during the account holder’s lifetime.

But, similar to the 4% rule, one size may not fit all. Your annual expenses might not align with the RMDs calculated by the IRS, leading to potential issues. If your expenses are lower, you might find yourself with a higher tax bill. This could mean your RMDs may fall short of covering your needs.

And what if you retire well before RMD age? You’ll need to come up with a withdrawal strategy for those years first.

It’s essential to weigh your financial requirements against this tax-driven strategy, recognizing that the RMD approach may be more of a starting point than a complete solution.

Take the guesswork out of retirement withdrawals and use an RMD Calculator to plan with confidence.

About This Calculator

This calculator estimates RMDs by dividing the user's prior year's Dec. 31 account balance by the IRS Distribution Period based on their age. Users can enter their birth year, prior-year balances and an expected annual return to estimate the timing and amount of future RMDs.

For IRAs (excluding Roth IRAs), users may combine balances and take the total RMD from one or more accounts. For 401(k)s and similar workplace plans*, RMDs must be calculated and taken separately from each account, so balances should be entered individually.

^*The IRS allows those with multiple 403(b) accounts to aggregate their balances and split their RMDs across these accounts.

Assumptions

This calculator assumes users have an RMD age of either 73 or 75. Users born between 1951 and 1959 are required to take their first RMD by April 1 of the year following their 73rd birthday. Users born in 1960 and later must take their first RMD by April 1 of the year following their 75th birthday.

This calculator uses the IRS Uniform Lifetime Table to estimate RMDs. This table generally applies to account owners age 73 or older whose spouse is either less than 10 years younger or not their sole primary beneficiary.

However, if a user's spouse is more than 10 years younger and is their sole primary beneficiary, the IRS Joint and Last Survivor Expectancy Table must be used instead. Likewise, if the user is the beneficiary of an inherited IRA or retirement account, RMDs must be calculated using the IRS Single Life Expectancy Table. In these cases, users will need to calculate their RMD manually or consult a finance professional.

For users already required to take an RMD for the current year, the calculator uses their account balance as of December 31 of the previous year to compute the RMD. For users who haven't yet reached RMD age, the calculator applies their expected annual rate of return to that same prior-year-end balance to project future balances, which are then used to estimate RMDs.

This RMD calculator uses the IRS Uniform Lifetime Table, but certain users may need to use a different IRS table depending on their beneficiary designation or marital status. It's the user's responsibility to confirm which table applies to their situation, and tables may be subject to change.

Actual results may vary based on individual circumstances, future account performance and changes in tax laws or IRS regulations. Estimates provided by this calculator do not guarantee future distribution amounts or account balances. Past performance is not indicative of future results.

Hurdle Rate vs. Safe Withdrawal Rate

A safe withdrawal rate is the amount a person can withdraw annually from their savings without running out of money. However, a hurdle rate represents a minimum acceptable return on investment or a portfolio. It helps individuals assess the viability of different retirement savings vehicles and investment opportunities in achieving their long-term financial goals.

Hurdle rate influences decisions regarding the selection of retirement income sources. Individuals may evaluate retirement vehicles, such as annuities, pensions and Social Security benefits, based on their ability to generate returns that meet or exceed the hurdle rate. Understanding how these income streams contribute to overall retirement income can help construct a diversified and sustainable retirement income plan.

In short, a hurdle rate shapes how a portfolio is invested. Meanwhile, a safe withdrawal rate determines how much you can reasonably draw so your portfolio lasts as long as you need it to.

Bottom Line

A woman who's approaching retirement calculates how much she can afford to safely withdrawal from her account each year.

When planning for a financially secure retirement, identifying a safe withdrawal rate is important to preserve your nest egg. This is the percentage of total assets you can withdraw annually to ensure your money lasts for a minimum number of years. While the 4% rule is a common example of a safe withdrawal rate, it has several limitations and potential risks. Finding a safe withdrawal rate may require targeted planning for your specific needs and greater flexibility.
