Retirement Self-Sabotage: 5 Common Mistakes That Can Derail Your Plan

From Kevin Kern’s Live Plan Invest Podcast Episode #37

In a recent episode of the Live Plan Invest podcast, we unpacked five surprisingly common mistakes that can quietly undermine even the best-laid retirement plans. These aren’t obscure missteps—they’re behaviors that many retirees fall into without even realizing the long-term consequences.

1. Not Having a Written Plan

You wouldn’t build a house without a blueprint—so why enter retirement without a plan?

Too often, people delay planning out of procrastination, overconfidence, or a lack of financial literacy. Some assume Social Security or a pension will be “enough,” while others think their 401(k) balance is the plan.

A written retirement plan goes far beyond investment accounts. It includes strategies for income, taxes, healthcare, and managing longevity risk. Yet 56% of Americans still don’t have a formal financial plan, according to Allianz Life’s 2024 Retirement Study.

The result? Missed opportunities, preventable tax mistakes, and an increased risk of running out of money.

Takeaway: Confidence in retirement rises dramatically with a plan. Start one early—and revisit it often.

2. Overspending Early in Retirement

The first few years of retirement—the “go-go years”—are often the most active, and the most expensive. Travel, renovations, and family gifts add up quickly.

But overspending early can trigger something called sequence-of-returns risk: withdrawing from your portfolio during a market downturn can severely weaken long-term growth potential. Without proper income planning, early withdrawals can put your entire retirement timeline at risk.

Takeaway: Build a retirement income strategy that accounts for both spending goals and market volatility in the early years. Limit your income distributions to dividends and interest and avoid using principal when ever possible.

3. Ignoring Tax Efficiency

Even retirees who save diligently often ignore one of their biggest silent threats: taxes.

From Required Minimum Distributions (RMDs) to Medicare premium surcharges (IRMAA), failing to coordinate income, withdrawals, and account types can erode retirement income. Many retirees also overlook Roth conversions, asset location strategies, and Qualified Charitable Distributions (QCDs)—tools that could save thousands annually.

Takeaway: Retirement is a tax puzzle. Coordinated planning can help you keep more of what you’ve earned.

4. Investing Too Conservatively—or Too Aggressively

Emotion drives many investment decisions—especially in retirement. Market volatility causes some retirees to panic-sell or shift entirely to cash, missing out on future growth. Others chase returns and take on more risk than they can afford.

Both ends of the spectrum are dangerous. Without a balanced portfolio tailored to your income needs and risk tolerance, you risk either outliving your assets or losing too much during downturns.

Takeaway: Don’t let short-term fear derail your long-term plan. Stick to a diversified strategy that aligns with your goals.

5. Underestimating Healthcare and Long-Term Care Costs

A 65-year-old couple today may need over $300,000 just to cover healthcare in retirement—not including long-term care. And Medicare doesn’t cover everything: dental, vision, hearing, and extended care are all excluded.

Medical costs also tend to outpace general inflation, placing a growing burden on fixed incomes. Planning ahead is essential to avoid draining assets prematurely.

Takeaway: Don’t treat healthcare as a footnote in your plan—make it a central part of your retirement strategy.

Bonus Sabotage: Planning Alone in a Two-Spouse Household

When only one spouse manages the finances, the other can be left unprepared and overwhelmed if something happens. This dynamic not only creates risk in the event of death or illness, but it can also lead to misaligned retirement goals or missed opportunities for tax optimization.

Takeaway: Retirement planning should be a team sport. Include both spouses in key decisions and make sure both understand the plan.

Final Thought: The Best Way to Avoid Retirement Sabotage?

“Have a written, flexible plan—and revisit it often.”

Retirement isn’t a set-it-and-forget-it experience. Markets shift. Tax laws change. Life evolves. A living plan, paired with clear communication and discipline, is your best defense against the avoidable mistakes that can quietly sabotage your financial future.
