Retirement Investment Planning Mistakes a CFP® Sees Often

September 23, 2026

Nobody plans to make a costly mistake with their retirement money. Yet certain retirement investment planning mistakes that CFP® professionals see again and again, and they quietly chip away at savings over time.

Maybe it's pulling money from the wrong account first. Maybe it's holding too much risk right before retiring. Small missteps, big consequences.

At RKM Financial Services, we walk clients through the patterns that trip people up most. Here's what to watch for, and how a CFP® typically catches these before they become expensive.

Mistake #1: Ignoring Withdrawal Order

Many retirees pull from savings without a real plan for sequence. Withdrawing from tax-deferred accounts too early can push you into a higher bracket than necessary.

A CFP® often builds a tax-efficient withdrawal strategy that blends taxable, tax-deferred, and Roth sources. Getting this wrong can cost thousands over a 20-year retirement.

Mistake #2: Staying Too Aggressive Too Long

Holding a growth-heavy portfolio right up until retirement is one of the most common retirement portfolio risk mistakes. A market downturn at the wrong moment can set your timeline back years.

Shifting toward a more balanced mix as retirement nears is not about giving up on growth. It's about protecting what you've already built.

Mistake #3: Skipping Estate and Legacy Coordination

Investment decisions rarely stand alone. Yet many people separate their portfolio from their estate planning for retirees, which can create gaps for a spouse or kids down the road.

A CFP® often coordinates beneficiary designations with your broader investment strategy. This matters even more for blended families with step-kids or grandkids in the picture.

Mistake #4: Underestimating Healthcare and Longevity Costs

According to Fidelity's annual retiree health cost estimate, a typical 65-year-old couple can expect a substantial six-figure sum in healthcare costs throughout retirement. Many portfolios simply don't plan for this.

A CFP® builds a cushion into your retirement income planning for these costs, rather than treating them as a surprise. Longevity planning is part of the same conversation.

Let's make it simple: a small buffer now avoids a bigger scramble later.

Quick Takeaways

  • Withdrawal order matters as much as savings totals for tax efficiency.
  • Staying too aggressive too close to retirement is a common retirement portfolio risk mistake.
  • Estate planning for retirees should tie directly into investment decisions.
  • Healthcare and longevity costs deserve a real place in your plan, not an afterthought.
  • A CFP® coordinates these pieces so nothing falls through the cracks.

Conclusion

Retirement investment planning mistakes CFP® professionals flag most often tend to come down to timing and coordination, not lack of effort. Withdrawal order, risk shifts, estate coordination, and healthcare costs all connect to one another.

At RKM Financial Services, we look at the full picture rather than one account at a time. Whether you're retired already or a few years out, catching these patterns early makes a real difference.
