Why the 4% Safe Withdrawal Rule Can Fail in 2026 and What to Use Instead
Short answer: The 4% rule can fail today because it was built for a world with higher bond yields and lower stock valuations. When William Bengen created it in 1994, 10-year Treasury yields were around 6% and the Shiller CAPE ratio was about 20. Today, the 10-year Treasury yield is approximately 4.3% and the Shiller CAPE ratio is 40.34 — more than double its historical average. Morningstar's 2025 research recommends a 3.9% starting withdrawal rate for a 90% chance of not running out of money over 30 years, and even that does not account for the worst five-year inflation stretch in 40 years (22.5% cumulative from 2021 to 2025). Lifestyle-First planning secures your essentials with Protected Lifetime Income first, then uses flexible withdrawals for everything else.
Let's talk about your goals and lifestyle first — no numbers required.
Why the 4% Rule Was Built for a Different Era
The 4% rule was first introduced by William Bengen in 1994 and later popularized by the Trinity Study. It says you can withdraw 4% of your starting retirement portfolio each year (adjusted for inflation) and expect your money to last 30 years. But the world has changed since then. Back in 1994, 10-year Treasury yields were around 6%, and the Shiller CAPE ratio—a measure of stock market valuation—was about 20, close to its long-term average of 17.36. Today, the 10-year Treasury yield is about 4.3%, and the Shiller CAPE ratio is 40.34—more than double the historical average (see current CAPE). Morningstar’s 2025 research (see Morningstar) now recommends a 3.9% starting withdrawal rate for a 90% chance of not outliving your savings over 30 years.
What Has Changed Since the Rule Was Created
Since 1994, the 10-year Treasury yield has dropped from about 6% to 4.3%, and the Shiller CAPE ratio has jumped from around 20 to 40.34—more than double its long-term average of 17.36. On top of that, cumulative inflation from 2021 to 2025 was 22.5%, the worst five-year stretch in 40 years. All three forces—lower yields, higher valuations, and higher inflation—work together to make fixed withdrawal rates riskier than ever for today’s retirees.
Sequence of Returns Risk: Why Timing Beats Averages
Sequence-of-returns risk means that poor markets early in retirement can permanently damage your withdrawal strategy, even if your average return over 30 years is strong. Wade Pfau’s research shows that about 77% of your final retirement outcome is determined by the returns in just the first five to ten years of retirement. If you’re withdrawing money during a downturn, you have to sell more shares at low prices, locking in losses and increasing the risk of running out of money. Accumulation portfolios aren’t affected the same way—withdrawals make all the difference.
Real-World Proof: What Early Losses Can Do
- 1973–74 bear market: S&P 500 dropped 48%, inflation averaged 9.3% per year. A retiree who started withdrawals in 1973 lost about 30% in just two years, not counting inflation. Kitces research shows Client A retiring at the start ended with $278,000 after 30 years, while Client B two years later ended with $3.36 million—even though their average returns were similar. (see Kitces)
- 2000–02 dot-com crash: S&P 500 lost 47.2%. A $1M portfolio withdrawing $40,000 per year was nearly cut in half by the end of year three.
- 2008–09 financial crisis: S&P 500 fell 54%. Retirees who started withdrawals just before the crash saw sharp drops, but the market rebounded quickly, so 4% rule portfolios could recover—showing the length of the downturn matters as much as the depth.
- Mason vs. Dixon: Mason retired in 1983 with $400,000 and ended with nearly $2.7 million after 30 years. Dixon retired in 1967 with over $2.1 million but ran out of money before 30 years due to poor early returns and high inflation.
How Lifestyle-First Planning Protects What Matters Most
Instead of relying on a fixed withdrawal rule, Lifestyle-First planning covers your essentials and non-negotiable experiences with Protected Lifetime Income (PLI) first, so you never have to cut what matters most. Then, it uses adaptive withdrawals from your growth assets for upgrades, flexibility, and legacy. BlackRock research shows retirees with a guaranteed income floor can increase their potential spending by 22% on average compared to withdrawal-only strategies. Guardrails research shows 15% higher median ending balances over 30 years compared to static rules. Once essentials are covered with PLI, many clients find they can invest remaining assets more confidently for long-term growth.
Myths and Truths About the 4% Safe Withdrawal Rule
- Myth: The 4% rule is still safe for everyone.
Truth: Morningstar's 2025 research recommends 3.9% as the highest starting rate with 90% confidence, and even that can fail if markets drop early or inflation spikes. - Myth: Average returns are all that matter.
Truth: The order of returns matters far more than the average. About 77% of your portfolio's final outcome is determined by the first five to ten years. - Myth: The 4% rule works in any market environment.
Truth: It was built on 1994's higher bond yields and lower valuations. Today's Shiller CAPE of 40.34 and 4.3% Treasury yields make fixed rules much riskier. - Myth: If the 4% rule fails you can just cut spending.
Truth: Cutting spending during a downturn is painful and often unrealistic for essentials. Lifestyle-First planning covers must-have spending with PLI so you never face that choice. And would a retirement where you had to cut spending really feel like a "successful" retirement? - Myth: Protected Lifetime Income means giving up all growth.
Truth: PLI is used only for essentials. The rest of your savings continues to grow, giving you upgrades, flexibility, and legacy. - Myth: Guardrails strategies are too complicated for most people.
Truth: Guardrails are designed to be simple and rules-based, and research shows they produce 15% higher median ending balances. But they still can't fully protect you from potentially having to cut spending during bad market stretches.
Pros and Cons: 4% Rule vs. Lifestyle-First with PLI
Pros of the 4% Rule:
- Simple and easy to follow
- Provides a clear starting point for planning
- Historically provided high success rates in U.S. markets over 30-year periods based on past data
Cons of the 4% Rule:
- Built on outdated assumptions of higher bond yields and lower stock valuations
- Vulnerable to sequence-of-returns risk especially if markets drop early
- Does not account for today's lower yields, higher inflation, or fees and taxes
- Can force spending cuts at the worst possible time
- Less reliable for retirements lasting longer than 30 years
Pros of Lifestyle-First with PLI and Adaptive Withdrawals:
- Secures essentials with Protected Lifetime Income so your lifestyle is protected no matter what markets do
- Uses adaptive withdrawals for upgrades and legacy
- BlackRock research shows 22% higher potential spending vs. withdrawal-only strategies
- Guardrails component produces 15% higher median ending balances over 30 years
- Reduces sequence-of-returns risk and the need for forced spending cuts
- Retirees with PLI floors often invest remaining assets more aggressively for better long-term growth
Cons of Lifestyle-First with PLI:
- Requires careful upfront planning to define essentials and set up PLI
- Some assets are set aside for protected income which may reduce near-term liquidity for other goals
- More moving parts than a simple rule so it benefits from ongoing review and coordination

Frequently Asked Questions
Is the 4% rule still safe?
Morningstar's 2025 research recommends a 3.9% starting withdrawal rate for 90% confidence over 30 years, and even that can fail if markets drop early or inflation spikes unexpectedly. The Shiller CAPE ratio is currently over 40, more than double its historical average, meaning stock valuations are high and future returns could be lower. For most retirees in 2026, relying solely on any fixed withdrawal rule is a significant risk that deserves a better plan.
What's a smart withdrawal strategy in retirement?
A smart strategy covers essentials with Protected Lifetime Income first, then pulls from growth assets adaptively based on market conditions. Guardrails strategies set upper and lower spending bands so you spend more when markets are strong and pull back a little when they're not. Research shows this approach produces 15% higher median ending balances over 30 years compared to the static 4% rule.
How does sequence of returns risk threaten retirees even with average returns?
Sequence of returns risk means that poor markets early in retirement force you to sell investments at a loss to cover spending, permanently reducing your portfolio even if average returns look strong over 30 years. Wade Pfau's research shows 77% of your final retirement outcome is determined by what markets do in your first five to ten years. Having a guaranteed income floor means you never have to sell at the worst time to cover your essentials.
How do I protect against inflation and sequence risk?
The strongest protection is a two-layer approach: cover must-have expenses with Protected Lifetime Income so your essentials are never tied to market performance, then use growth-oriented assets for long-term purchasing power. Buffer assets and staged income activations give you flexibility to avoid selling investments during downturns. Review your plan annually to keep pace with rising healthcare costs and other inflation pressures.
What is guaranteed retirement income?
Guaranteed retirement income is money that arrives every month for the rest of your life no matter what the market does. It can come from Social Security, a pension, or a Protected Lifetime Income (PLI) solution. When your essential expenses are covered by guaranteed income, you can invest the rest of your money more confidently and spend freely on the experiences and adventures that make retirement worthwhile.
Are annuities ever a fit in a retirement plan?
When used strategically as Protected Lifetime Income to cover essentials, the right solution can be a powerful fit in a floor-and-upside strategy. Not all solutions are the same, and the details of payout rates, fees, and features matter enormously. When done right, a guaranteed income floor removes your essentials from market risk and can increase your overall spending potential by 22% according to BlackRock research.
Can bucket or guardrail strategies prevent spending cuts?
Guardrails strategies significantly reduce the risk of spending cuts by adjusting withdrawals dynamically as markets move, and research shows they produce 15% higher median ending balances over 30 years compared to static rules. However, your essential spending is still tied to portfolio performance in these approaches. Pairing guardrails with Protected Lifetime Income for your true must-haves gives you the strongest possible foundation.
How do Roth conversions lower lifetime taxes?
Roth conversions move money from tax-deferred accounts into a Roth IRA where future growth and withdrawals are completely tax-free. Done in the right years, usually after retirement but before Required Minimum Distributions begin, conversions reduce future RMDs, lower taxable income, and help you stay below Medicare IRMAA thresholds. Roth withdrawals do not count toward Modified Adjusted Gross Income, giving you more control over your tax bill and more predictability in your income plan.
What is IRMAA and why does it matter for retirement income planning?
IRMAA is the income-related Medicare premium surcharge that kicks in when your Modified Adjusted Gross Income exceeds certain thresholds. In 2026, a single filer with MAGI over $109,000 sees their Medicare Part B premium jump from $202.90 to $284.10 per month. Every dollar of retirement income you manage carefully, including how you structure withdrawals and when you do Roth conversions, can affect how much you pay for Medicare each year.
When should I claim Social Security?
The right time to claim Social Security is different for everyone and can affect your monthly benefit for the rest of your life. Claiming at 62 gets you income sooner but locks in a permanently reduced payment; waiting until 70 can increase your benefit by up to 32% compared to your full retirement age amount. If you have Protected Lifetime Income covering your essentials in the meantime, delaying Social Security is often one of the highest-return decisions available.
What about Required Minimum Distributions (RMDs)?
RMDs are mandatory annual withdrawals from traditional IRAs and 401(k)s beginning at age 73 if born 1951 to 1959, or age 75 if born after 1959. They count as ordinary income and can push you into higher tax brackets, trigger IRMAA surcharges, and make more of your Social Security taxable. Strategic Roth conversions before RMDs begin can significantly reduce future RMD amounts and the tax damage they create.
Does Missouri tax Social Security benefits?
Missouri exempts most Social Security benefits from state income tax for retirees with moderate incomes, making it one of the more retirement-friendly states in the Midwest. Coordinating your Social Security income with withdrawals and Roth conversions can help you stay within the exemption thresholds and keep more of your income tax-free at both the state and federal levels.
Does Florida tax Social Security benefits?
Florida has no state income tax, which means Social Security benefits, retirement income, and investment withdrawals are all free from state taxation. This makes Florida one of the most favorable states for any withdrawal strategy and gives retirees there more flexibility in how they sequence income, convert to Roth, and take distributions.
Does Nebraska tax Social Security benefits?
Nebraska is phasing out its state tax on Social Security benefits, and most retirees will see little or no state Social Security tax in the coming years. This ongoing change makes early Roth conversion strategies and guaranteed income planning increasingly compelling for Nebraska residents who are planning ahead now.
Does Kansas tax Social Security benefits?
Kansas exempts Social Security benefits from state tax for retirees with federal Adjusted Gross Income under $75,000. Staying under that threshold can be part of a broader withdrawal strategy that includes Roth conversions and careful management of PLI income, helping Kansas retirees keep their total tax burden meaningfully lower.
Does Iowa tax Social Security benefits?
Iowa does not tax Social Security benefits for retirees age 55 or older, making it one of the stronger states for retirement income planning in the region. Iowa retirees have more room to manage federal tax thresholds through Roth conversions and strategic withdrawals without worrying about a parallel state tax hit on Social Security income.
