Top Retirement Planning Mistakes Pre-Retirees Make in Mid-Year Reviews
Why Mid-Year Reviews Are the Best Time to Catch Retirement Planning Mistakes
Retirement planning mistakes can silently erode decades of hard-earned savings, and the worst part is that most people don’t spot them until it’s too late to course-correct.
Here are the most common ones to watch for during a mid-year review:
- Underestimating post-retirement expenses — costs often rise, not fall
- Ignoring sequence-of-returns risk — early market drops are far more damaging once you’re withdrawing
- Missing a tax-aware withdrawal strategy — unplanned distributions can push you into higher brackets
- Delaying savings or making early withdrawals — both permanently disrupt compound growth
- Overlooking healthcare and long-term care costs — Medicare doesn’t cover everything
- Miscalculating Social Security and RMD timing — claiming too early can cost you 30% of your monthly benefit
The numbers make the urgency clear. A full 55% of people who retired in the last five years regret how they saved, and only 40% stayed on track with their original budget, according to Nationwide’s 2026 Advisor Authority study. In a separate Morgan Stanley analysis, 72% of adults over 50 said they fear their retirement costs will spiral out of control.
And yet, many pre-retirees treat their mid-year financial review as a passive checkbox exercise, glancing at account balances and moving on. That’s a costly habit.
The mid-year mark is actually a powerful window. You have enough real spending data from the first half of the year to spot patterns, and you still have time to make tax-year adjustments before December. It’s the ideal moment to stress-test your plan, not just review it.

The Most Costly Retirement Planning Mistakes to Avoid
When it comes to securing your financial future, what you don’t know or what you choose to ignore can cost you hundreds of thousands of dollars. Many pre-retirees focus entirely on growing their account balances, completely neglecting portfolio protection and risk management.
As you transition toward retirement, your primary financial objective must shift from aggressive growth to capital preservation and reliable income generation. Failing to make this mental and strategic shift is one of the most devastating retirement planning mistakes you can make.
To ensure your portfolio is resilient enough to withstand economic shifts, you must proactively address these vulnerabilities during your mid-year review. Taking the time for comprehensive retirement planning preparation now prevents costly, irreversible errors later. According to industry research, failing to adjust asset allocations as you near retirement is a primary driver of avoidable financial loss.
Underestimating Post-Work Expenses
One of the most common myths in retirement planning is that your expenses will naturally drop by 20% to 30% the moment you stop working. While you might save money on daily commutes and professional attire, other costs frequently rise.
During your mid-year review, it is vital to perform rigorous budget tracking. Many pre-retirees hit lifestyle inflation early in retirement, when they suddenly have 40 hours of free time every week. Travel, hobbies, and dining out can quickly drain an unmonitored account. Fixed costs like housing, property taxes, and home maintenance also rarely decrease, and often climb.
To avoid this trap, you must accurately calculate how much I need to retire based on realistic post-work spending. Interactive tools like our Needs, Wants, Wishes Calculator help you categorize your future expenses, so your essential needs are covered by guaranteed income sources while you leave room for your lifestyle wishes.
Ignoring Sequence-of-Returns Risk and Market Volatility
If you experience a severe market downturn in the first few years of your retirement, it can permanently damage your portfolio’s longevity. This phenomenon is known as sequence-of-returns risk.
When you are actively saving, market drops are actually buying opportunities. But when you are retired and withdrawing money, selling depreciated assets to fund your living expenses locks in those losses. This accelerated portfolio depletion can cut years off your retirement runway.
Fidelity’s research illustrates the danger: a portfolio that drops at least 15% in the first year of retirement, paired with withdrawals of at least 3.3% of the balance, faces a far higher chance of running dry within 30 years.
During your mid-year review, evaluate your exposure to market volatility. Implementing a capital preservation strategy that isolates several years of living expenses in stable, liquid vehicles can shield your primary investment engine from short-term market swings. Understanding how sequence of returns risk works is essential to protecting your lifestyle.

Failing to Build a Tax-Aware Withdrawal Strategy
What you keep matters more than what you earn. Many pre-retirees mistakenly assume their tax bracket will automatically drop in retirement. If most of your savings sit in traditional 401(k)s or IRAs, every dollar you withdraw is taxed as ordinary income.
Without proper tax diversification across taxable, tax-deferred, and tax-free accounts, large, lump-sum withdrawals for a dream vacation or a new car can inadvertently push you into a higher tax bracket, increase your Medicare premiums, and trigger taxes on your Social Security benefits. According to advisors, ignoring tax diversification is one of the top 12 Retirement Mistakes That Cost $100K + over the course of a retirement.
Your mid-year review is the perfect window to evaluate tax-efficient strategies, such as partial Roth conversions. By systematically converting highly taxed pre-tax assets into tax-free Roth accounts during lower-income years, you can build a highly tax efficient retirement that minimizes your lifetime tax liability.
Delaying Savings and Tapping Accounts Early
The power of compound interest is your greatest ally, but only if you give it time to work. Delaying your savings goals, even by just a few years in your 40s or 50s, requires you to save exponentially more later to achieve the same result.
Conversely, tapping into retirement accounts early is one of the most damaging retirement planning mistakes pre-retirees make. Whether it is to fund a child’s education, pay off a mortgage early, or cover an emergency, early withdrawals permanently disrupt compounding and trigger steep penalties. Many workers also leave forgotten accounts behind at previous employers. As of July 2025, an estimated 31.9 million left-behind 401(k) accounts held roughly $2.1 trillion in assets, according to Capitalize and the Center for Retirement Research.
To avoid leaving money on the table, review your old accounts during your mid-year checkup. For more guidance on managing workplace plans, see these 5 Retirement Planning Mistakes to Avoid by Wells Fargo.
Overlooking Healthcare, Long-Term Care, and Longevity Costs
Many pre-retirees assume that Medicare will cover all of their medical needs once they turn 65. In reality, Medicare features deductibles, co-pays, and premium surcharges that can add up to hundreds of thousands of dollars over a typical retirement.
Per Fidelity’s annual estimate cited by Morgan Stanley, the average 65-year-old couple will need about $315,000 in today’s dollars for medical expenses in retirement, excluding long-term care. Long-term care is the bigger exposure. Traditional health insurance and Medicare do not cover custodial care such as assisted living or nursing homes. A 65-year-old has roughly a 70% chance of needing some form of extended care, and about 1 in 5 will need it for more than five years. Ignoring this risk leaves your entire estate vulnerable to being wiped out by a single health crisis.
During your mid-year review, evaluate your healthcare coverage, explore long-term care insurance options, and consider hybrid policies that offer both life insurance benefits and long-term care protection if needed.
Miscalculating Social Security Claiming Strategies and RMDs
When should you claim Social Security? Many people rush to claim benefits at age 62, failing to realize that doing so permanently reduces their monthly payout by up to 30% compared to their Full Retirement Age (FRA). Conversely, waiting until age 70 can increase your monthly benefit by 8% per year of delay.
At the same time, you must plan for Required Minimum Distributions (RMDs). The government will eventually force you to withdraw a percentage of your tax-deferred accounts each year, whether you need the money or not. If you haven’t planned for these distributions, they can create a massive, unexpected tax bill.
Choosing the right Social Security claiming age and mapping out your future RMD obligations during your mid-year review is essential to keeping your lifetime tax burden as low as possible.
Key Takeaways: Maximizing Your Mid-Year Financial Review
Catching wealth-eroding mistakes requires moving past basic balance monitoring to stress-test how your portfolio handles real-world economic risks.
- Verify Actual Expenses: Do not assume expenses automatically drop post-work; cross-reference your actual mid-year spending data to account for lifestyle inflation and fixed housing costs.
- Insulate Against Volatility: Establish a dedicated capital preservation runway to mitigate sequence-of-returns risk, preventing the need to sell equities in down markets.
- Build Tax Diversification: Coordinate your taxable, tax-deferred, and tax-free accounts to navigate unexpected tax brackets and avoid steep Medicare premium surcharges.
- Account for Healthcare Realities: Build independent long-term care and healthcare spending buffers into your plan, recognizing that standard Medicare coverage leaves major out-of-pocket gaps.
