A great retirement plan doesn’t just grow your savings — it turns your savings into income you can actually live on.
At Brindle & Bay, we’ve worked with hundreds of families to design sustainable, flexible withdrawal strategies that are aligned with how they want to live. Retirement is a major life transition, and the way you take income matters more than most people realize.
In this post, we’ll share the three most common pitfalls we see in retirement income planning — and how to build a plan that gives you confidence not just on day one of retirement, but for the long haul.
Mistake #1: Ignoring Market Volatility
Let’s say you retire with $1,000,000 and expect to withdraw 6% annually. You’ve read that the market averages 8-10% per year, so you assume that’s safe. It’s actually not!
Here’s why: average returns aren’t the same as consistent returns. The order in which returns show up matters a lot, especially in your first few years of retirement. This is called sequence of returns risk.
If the market drops early in your retirement (think -12%, -22%, etc.), even strong long-term averages might not save you. We’ve seen hypothetical million-dollar portfolios drained in 12 years because the first few years were rocky.
This is where the “4% Rule” came from. It’s a rough, oversimplified answer to the question: What’s the most I can withdraw without going broke, even in the worst-case scenario?
Traditional models like the 4% rule retirement withdrawal method are too rigid for today’s retiree. Instead, dynamic retirement withdrawal strategies — like the modern guardrails approach — adjust your income as conditions change, offering more flexibility and peace of mind.
That’s why we recommend a modern dynamic guardrails approach.
The modern dynamic guardrails system uses sophisticated modeling to monitor your plan in real time. It allows for inflation-adjusted withdrawals, it signals when adjustments are needed, and it empowers you to spend more when things are going well. It’s built for your life, not someone else’s worst-case scenario.
Mistake #2: Mismanaging Your Investment Allocation
Asset allocation is more than just a question of how to balance stocks and bonds. It’s about structuring your investments to deliver the returns you need without putting your whole plan at risk. Effective retirement investment allocation isn’t just dialing down risk, but setting up your portfolio for sustainable income.
There are two classic missteps. You can be too conservative, lacking the growth to keep up with inflation and spending. Or you might be too concentrated (often in large-cap tech stocks), which means volatility when you’re seeking stability.
The first five years of your retirement are critical. It resembles a certain kind of financial lottery. Good luck early can enhance your entire plan. Bad luck early might sink it.
Modern thinking by experts like Michael Kitces and Dr. Wade Pfau now favors a rising equity glide path. That means starting a little more conservatively, then gradually increasing your stock exposure as you age.
It might sound backward and counterintuitive, but it works — especially when paired with smart withdrawal strategies like our guardrails system. It reduces early risk while helping you stay ahead of inflation.
Mistake #3: Underestimating Taxes and Inflation
Suppose your employer gives you a raise to keep up with inflation. In retirement, you’re the employer now.
Add to that the tax complexity of retirement income — RMDs, Social Security taxation, Medicare IRMAA brackets — and you’ve got a recipe for surprise tax bills that shrink your spendable income. Many retirees don’t anticipate how required minimum distributions (RMDs) or Social Security taxation strategies will impact their cash flow—and these tax traps can cause real damage.
We see this constantly. Retirees either fail to plan for rising expenses or fall into tax traps they didn’t know existed. But you can plan for this by building inflation-adjusted withdrawals into your plan, use tax-efficient withdrawal sequencing to manage tax brackets, RMDs, and Social Security timing, and running income tax projections before the year even begins.
With the right strategy, you can anticipate the big risks (tax law changes, healthcare costs, inflation shocks) and inoculate yourself against them.
The Bottom Line
Most withdrawal plans fail not because people are reckless, but because they’re relying on reductive rules of thumb that don’t reflect reality.
Instead, people need:
-a plan that adapts to market conditions
-an allocation that evolves with your retirement timeline
-a withdrawal system that responds to success (or challenges)
-a tax-aware, inflation-conscious roadmap that doesn’t leave them guessing
A personalized retirement income plan should reflect your actual lifestyle, not just a spreadsheet. Whether you’re looking to protect against inflation, reduce taxes, or create a sustainable income stream, we’ll help you design a custom retirement withdrawal plan tailored to your life and your goals.
