Retirement Planning Mistakes: Common Pitfalls to Avoid
Much has been written about the classic financial mistakes that plague start-ups, family businesses, corporations, and charities. Retirees face their own set of common retirement mistakes, too.
Calling them “mistakes” may be a bit harsh — not all of them stem from poor judgment. Even so, becoming aware of these retirement planning pitfalls can help you avoid falling into them.
Common Retirement Planning Mistakes to Watch For
Below are some of the most frequent retirement financial mistakes people encounter, along with what to know about each one.
Mismanaging Social Security Timing
Social Security retirement planning is one of the most overlooked pieces of the puzzle. Your benefits are structured to increase by about 8% for every year you delay claiming them past your full retirement age.
Filing for monthly benefits before reaching full retirement age typically means smaller monthly payments for life. Is waiting a few extra years worth considering for your situation? It may be — but the right answer depends on your health, income needs, and overall retirement strategy.
Underestimating Healthcare Costs
Retirement healthcare costs are consistently underestimated. According to Fidelity’s 2026 Retiree Health Care Cost Estimate, a healthy couple retiring at age 65 can expect to pay roughly $371,000 in total out-of-pocket healthcare expenses throughout retirement — even with coverage such as Medicare Part D, Medigap, and dental insurance.
Having a strategy in place can help you prepare for these costs before they arrive.
Underestimating Longevity
One of the more subtle retirement pitfalls is failing to plan for a long life. Actuaries at the Social Security Administration project that around a third of today’s 65-year-olds will live to age 90, and about one in seven will live to 95 or longer.
A 20- to 30-year retirement isn’t just possible — it should be expected. Planning for a shorter timeline can leave you financially exposed later in life.
Mismanaging Retirement Withdrawals
You may have heard of the “4% rule” — a general guideline suggesting you withdraw about 4% of your retirement savings each year. Retirement withdrawal strategies aren’t one-size-fits-all, and everyone’s situation is different. Still, having a guideline in place can help you plan more confidently.
Overlooking Tax-Efficient Withdrawal Order
Many people enter retirement holding investments in both taxable and tax-advantaged accounts. Which account should you draw from first?
There’s no universal answer. A qualified financial professional can review your full financial picture — including your goals and risk tolerance — to help determine the most tax-efficient withdrawal order for your situation.

Failing to Plan for Other Major Costs, Like College
There’s no “financial aid” program for retirement, and no such thing as a “retirement loan.” Yet some retirees stretch their savings thin trying to help cover a child’s or grandchild’s college costs.
A financial professional can help you review your anticipated income and expenses before committing to a long-term strategy — helping you find a balanced approach between funding your own retirement and supporting your family’s education goals.
Frequently Asked Questions
What are the most common retirement planning mistakes people make?
The most common retirement pitfalls include claiming Social Security too early, underestimating healthcare costs, underestimating how long retirement savings need to last, withdrawing savings too quickly, and not having a tax-efficient withdrawal strategy.
How does delaying Social Security affect my benefits?
Delaying Social Security past your full retirement age increases your monthly benefit by about 8% for each year you wait, up to age 70. Filing early, before full retirement age, results in a permanently reduced monthly payment.

What is the 4% rule in retirement withdrawal strategies?
The 4% rule is a general guideline suggesting retirees withdraw about 4% of their retirement savings annually to help make those savings last. It’s a starting point, not a fixed formula — the right withdrawal rate depends on your individual circumstances.
Should I help pay for my children’s college if it affects my retirement savings?
There’s no financial aid or loan program for retirement, so many financial professionals recommend prioritizing retirement savings first. A financial professional can help you find a balanced approach between college funding and your own long-term retirement goals.
