Retirement is supposed to be the time when you finally get to enjoy the fruits of your decades of hard work. But here's the catch: many retirees feel constrained by the traditional '4% rule,' which limits how much they can withdraw from their savings each year. What if I told you there’s a way to potentially withdraw more—and still keep your retirement nest egg secure?
In our recent annual study on safe withdrawal rates (https://www.morningstar.com/lp/the-state-of-retirement-income), my colleagues Tao Guo, Jason Kephart, Christine Benz, and I explored strategies that could allow retirees to boost their starting withdrawal rates. We analyzed nine different approaches, all designed to outpace the conventional 4% rule originally developed by Bill Bengen. (For those interested in maximizing lifetime spending or leaving a legacy, I’ve previously discussed those strategies here: https://www.morningstar.com/retirement/heres-how-you-can-spend-more-during-retirement and https://www.morningstar.com/retirement/best-retirement-strategies-leaving-money-behind.)
Why focus on starting withdrawal rates? For many retirees, the early years of retirement are prime time for travel, dining out, and enjoying life while they’re still healthy and active. A higher starting withdrawal rate can make those early years even more fulfilling. But how do you achieve this without risking your financial security?
To find out, we tested 1,000 hypothetical return patterns over a 30-year period, using forward-looking return and volatility assumptions. Our goal was to identify the highest starting withdrawal rate that would leave retirees with a positive portfolio balance in at least 90% of the scenarios. For consistency, we assumed a portfolio allocation of 40% stocks and 60% bonds across all strategies.
And this is where it gets interesting: five strategies emerged as clear standouts for maximizing starting withdrawal rates. Let’s dive into how they work—and the trade-offs you need to consider.
1. Constant Percentage: 5.7% Starting Safe Withdrawal Rate
This method is refreshingly simple: withdraw a fixed percentage of your portfolio balance each year. For example, if you start with a $1 million portfolio, you’d withdraw $57,000 in the first year. The withdrawal amount adjusts annually based on your portfolio’s performance, but the percentage remains constant. To prevent drastic cuts, we set a floor so spending never drops below 90% of the initial withdrawal. But here’s the controversial part: this approach doesn’t account for inflation. Any increase in spending relies solely on portfolio growth, which can be unpredictable. Is this a risk you’re willing to take for higher initial withdrawals?
Example: Alice starts with a $1 million portfolio and withdraws 5.7%, or $57,000, in year one. After market fluctuations, her portfolio drops to $980,720. In year two, she withdraws 5.7% of the new balance, or $55,901.
2. Endowment: 5.7% Starting Safe Withdrawal Rate
Inspired by how university endowments manage spending, this method uses a 10-year average portfolio value to smooth out annual fluctuations. In the early years, withdrawals are based on the previous year’s ending balance. After year 10, a 10-year average is used. The catch? While this approach reduces volatility, it can still lead to significant spending cuts if the portfolio declines sharply. Is stability worth potentially sacrificing some flexibility?
Example: Bob starts with a $1 million portfolio and withdraws $57,000 in year one. By year three, his portfolio average is $975,890, and his withdrawal is $55,626.
3. Guardrails: 5.2% Starting Safe Withdrawal Rate
Developed by Jonathan Guyton and William Klinger, this method adjusts withdrawals annually based on portfolio performance. In strong markets, withdrawals can increase by up to 10% plus inflation; in downturns, they decrease. But here’s where it gets controversial: while this approach allows for higher initial spending, it requires retirees to be comfortable with fluctuating income. Can you adapt to a retirement ‘paycheck’ that changes every year?
Example: Claire starts with a $1 million portfolio and withdraws $52,000 in year one. If her portfolio grows to $1.4 million, her withdrawal could increase to $58,608 after adjustments.
4. Probability-Based Guardrails: 5.1% Starting Safe Withdrawal Rate
This method takes flexibility to the next level by reassessing the probability of success each year. If the odds of running out of money drop below 75%, spending is reduced by 10%; if they rise above 95%, spending increases by 10%. The trade-off? While this approach can lead to higher lifetime spending, it caps annual increases at 120% of initial spending (adjusted for inflation). Is this level of micromanagement worth the potential rewards?
Example: Diego starts with a $1 million portfolio and withdraws $51,000 in year one. After strong market returns, his spending increases by 10% to $56,100.
5. Vanguard Floor and Ceiling: 5.1% Starting Safe Withdrawal Rate
This Vanguard-inspired method sets limits on how much withdrawals can increase or decrease each year. With a 5% ceiling and a 2.5% floor, it aims to balance growth and preservation. The question is: does this middle-ground approach strike the right balance for your retirement goals?
Example: Elaine starts with a $1 million portfolio and withdraws $51,000 in year one. By year three, her withdrawal is capped at $58,183, even if her portfolio grows significantly.
The Bigger Picture: Benefits and Drawbacks
All five methods allow for greater lifetime spending compared to the traditional 4% rule. For instance, the guardrails and probability-based guardrails methods enable total lifetime spending of $1.36 million and $1.55 million, respectively. But here’s the trade-off: higher starting withdrawal rates often mean less money left at the end of retirement. The probability-based guardrails method, for example, leaves a median balance of just $230,000 after 30 years. If leaving a legacy is important to you, these strategies might not align with your goals.
Additionally, these methods involve variable spending, which can be challenging for retirees who prefer a steady income stream. The endowment, constant percentage, and Vanguard methods, in particular, can lead to significant spending cuts during market downturns. So, the question remains: are you willing to embrace uncertainty for the chance to enjoy more in your early retirement years?
Final Thoughts
Retirement planning isn’t one-size-fits-all. While these strategies offer exciting possibilities for boosting starting withdrawal rates, they require careful consideration of your risk tolerance, lifestyle preferences, and long-term goals. What’s your take? Are higher initial withdrawals worth the potential trade-offs, or do you prefer the safety of a more conservative approach? Let’s continue the conversation in the comments!
