- Lucas: So there's this idea in early retirement circles that once you pick a withdrawal rate, you just set autopilot and withdraw the same inflation-adjusted amount every year. And that can work, but it's also kind of a blunt instrument. Luna: Right — because real life isn't a straight line. Markets go up, they go down, and your spending probably doesn't stay flat either. Lucas: Exactly. And that's what today's episode is about: the Guardrails Spending Rule. It's a dynamic approach where you adjust your spending up or down based on how your portfolio is doing, but within a set of boundaries — guardrails — that keep you from making extreme cuts during a downturn or overspending in a boom. Luna: I've seen this called the 'spending smile' or 'ratcheting' in some corners. How does it actually work in practice? Lucas: So let's set up a simple example. Say you have a million-dollar portfolio and you start with a 4 percent withdrawal — that's $40,000 in year one. Now, the rule says you set a ceiling and a floor around that initial withdrawal rate. A common setup: the ceiling is 20 percent above your starting rate, and the floor is 20 percent below. So in dollar terms, your ceiling is $48,000 and your floor is $32,000. Luna: Okay, so those are your guardrails. And you only adjust spending if your actual withdrawal rate — based on current portfolio value — bumps against one of those rails? Lucas: Exactly. Each year, you calculate what your current withdrawal amount would be as a percentage of the portfolio's current value. If that percentage is below the ceiling, you don't increase spending. If it's above the floor, you don't cut. But if it hits the ceiling or goes above, you give yourself a raise — typically a 10 percent increase in spending. And if it drops below the floor, you cut spending by 10 percent. Luna: So it's like a shock absorber. Let's run that million-dollar example through a real market sequence. Say year one, market does well, portfolio grows to $1.1 million. Your withdrawal is still $40,000, so your withdrawal rate is about 3.6 percent — that's below the ceiling. No raise. Lucas: Right. Now year two, market tanks. Portfolio drops to $800,000. You're still taking $40,000, so your withdrawal rate jumps to 5 percent — that's above the floor of 4.8 percent, actually just barely. But if it dropped further to $750,000, your rate would be 5.33 percent — that hits the floor, so you'd cut spending by 10 percent to $36,000. Luna: And that cut is meant to protect the portfolio from depletion. But the psychological side is tough — you're cutting your lifestyle just when the market is already making you feel poor. Lucas: It's the hardest part of any dynamic spending rule. But the research shows that these small, timely cuts can dramatically reduce sequence risk. The original paper from Jonathan Guyton and William Kessler in 2006 found that this kind of rule allowed for higher initial withdrawal rates — up to 5 or even 6 percent — with very high success rates over 30-year retirements. Luna: So you're trading a little bit of spending flexibility for a lot more safety. I can see why it's popular in the FIRE community. Lucas: Exactly. And there are variations. Some people use a 10 percent adjustment, others use 5 percent to be more gradual. Some set the guardrails at plus or minus 10 percent of the initial rate instead of 20. The key is that the rule gives you a framework to avoid making emotional decisions. Luna: One thing I've wondered: how do you handle inflation in this model? If you cut spending by 10 percent during a bear market, but inflation is running hot, you're effectively cutting even more in real terms. Lucas: That's a great point. The classic rule adjusts for inflation each year, but during a guardrail event, you override that adjustment. So in the cut year, you might not get an inflation bump — you just take the 10 percent cut. In subsequent years, if you're not hitting the guardrails, you resume inflation adjustments. So there's a tension between 'good' inflation — like intentional lifestyle creep — and 'bad' inflation from rising prices. The rule doesn't distinguish, which can be a flaw. Luna: I've seen some people suggest using a separate inflation buffer, like a TIPS ladder, to handle that. But that adds complexity. Lucas: Complexity is the enemy of sticking with a plan. I think the beauty of the guardrails approach is that it's simple enough to set up in a spreadsheet and you can check it once a year. You don't need to rebalance daily or make market timing calls. Luna: So let's talk about a specific scenario. Say you retired in 2021 with a million-dollar portfolio, 60/40 stocks and bonds. Starting withdrawal $40,000. 2022 was brutal — the S&P 500 down about 19 percent, bonds down too. By end of 2022, your portfolio might be around $820,000. Your $40,000 withdrawal is now 4.88 percent — that's above the 4.8 percent floor if you used a 20 percent band. So you'd cut spending to $36,000 for 2023. Lucas: And that cut would have been painful, but look at 2023: the market rebounded strongly. By end of 2023, your portfolio might be back near $950,000. Your withdrawal — still $36,000 — is now 3.8 percent, well below the ceiling. So no raise. But you've preserved capital and avoided overspending during the recovery. By 2024, if the market continues up, you might finally get a raise. Luna: So the rule forces you to be counter-cyclical — spend less after bad years, spend more after good years. That's exactly what sequence risk demands. Lucas: Right. And the research shows that the worst case for retirees is a big market drop early in retirement followed by a slow recovery. The guardrails rule helps you navigate that precisely by cutting spending when the portfolio is vulnerable. Luna: I want to ask about implementation. How do you handle non-portfolio income, like Social Security or a part-time job? Do those count toward the withdrawal? Lucas: Great question. The rule is typically applied to portfolio withdrawals only. So if you have $20,000 in Social Security, your portfolio needs to cover the gap. You'd calculate your withdrawal rate on the portfolio alone. Some people add a 'floor' of guaranteed income and then apply guardrails to the variable part. But the core logic is the same. Luna: And what about taxes? If you cut spending by 10 percent, you might also reduce your tax liability, which is a hidden benefit. Lucas: Absolutely. Especially if you're withdrawing from tax-deferred accounts — a lower withdrawal means lower taxable income. That can help with things like managing capital gains brackets or avoiding Medicare premium surcharges. Luna: So the guardrails rule is really a complete spending philosophy, not just a number. It requires a certain mindset — being okay with spending less in some years and not feeling like you're 'failing' at retirement. Lucas: That's the hardest part, honestly. The math is straightforward. The behavior is the challenge. But if you can commit to it, it's one of the most robust withdrawal strategies out there. Luna: You know, speaking of committing to something that makes a real difference — a lot of listeners have asked how they can support the show. And honestly, it's not about big gestures. A couple of dollars a month genuinely helps keep these episodes ad-free and coming every day. Lucas: Yeah, if our conversations have helped you think about your own financial independence differently — maybe you adjusted your spending plan or just felt more confident — then a small contribution goes a long way. It's buy me a coffee dot com slash fexingo. No pressure, but it does make a real impact. Luna: And we're grateful for every one of you who listens. Now, back to guardrails — one last nuance: what about the 'ceiling' in a raging bull market? If the portfolio doubles, you could potentially raise spending significantly. Does the rule have a cap? Lucas: The classic rule doesn't have a cap, but you could impose one if you want to avoid lifestyle inflation that might be hard to reverse. Some people set a maximum annual increase of 10 or 15 percent. The key is that the guardrails provide a lower bound too, so you don't overshoot in either direction. It's a balancing act. Luna: And if you're curious, we'll put a link to the Guyton-Kessler paper in the show notes along with a simple spreadsheet template. Lucas: This is one of those tools that can turn a rigid retirement plan into a resilient one. And resilience, not optimization, is what really matters over a 40-year horizon.
