The most common retirement planning mistakes follow a recognizable pattern: not saving enough, claiming Social Security before the optimal age, failing to account for healthcare costs before Medicare, ignoring taxes on withdrawals, and going into retirement without a written drawdown plan. Federal surveys and financial planning research consistently surface them. The sections below cover all 13, with a specific fix for each.
Most planning mistakes don’t look like mistakes until years later. Retirement planning isn’t taught. The people who get it right mostly learn from what others got wrong.

#1: Not Tracking Monthly Spending Is Where Most Retirement Plans Break Down
Only 44% of Americans maintain a household budget, according to Discover Financial Services research. That number matters far more in retirement than it does during working years. When a paycheck is coming in, rough mental accounting can get you by. When you’re drawing down a fixed pool of savings, it can’t.
To build a retirement income plan, you need to know what you spend. Estimates are almost always too low. Most people forget recurring subscriptions, irregular expenses like car repairs and travel, and the way healthcare costs increase with age. A written budget built from real spending gives you data that estimates can’t. It also tends to reveal cuts you’d be glad to make once you see the numbers.
The fix: Set aside a weekend this month and pull every transaction from the last three months. Categorize it. That exercise tells you more about your retirement income needs than any calculator that starts from a guess.
#2: Most Americans Aren’t Saving Enough, and the Shortfall Is Bigger Than People Think
The median retirement account balance for American families is $87,000, according to the Federal Reserve’s 2022 Survey of Consumer Finances. That figure covers everyone with a retirement account. It rises to $185,000 for people aged 55 to 64, but 29% of non-retirees have nothing saved at all.
The mean ($333,940) is much higher than the median, pulled up by households with multi-million dollar accounts. The median is the more honest benchmark for most people. For most, $87,000 won’t last three years of retirement, let alone 25 or 30.
Retirement confidence reflects this reality. In the 2026 EBRI Retirement Confidence Survey, only 61% of workers said they feel confident they’ll have enough money to live comfortably throughout retirement. That’s a six-point drop from 2025 and one of the lowest readings since 2017.
The fix: If you’re 50 or older, catch-up contributions allow you to save an extra $7,500 annually in a 401(k), plus an extra $1,000 in an IRA. Even better, under recent SECURE 2.0 rules, workers aged 60 to 63 qualify for an enhanced ’super catch-up’ limit, allowing them to fast-track their savings even further. Home equity, part-time work in early retirement, and delayed Social Security claiming are other levers. Run the numbers in your plan before assuming the shortfall can’t be closed.
#3: Claiming Social Security Early Is the Single Most Expensive Retirement Timing Mistake
About 90% of Americans claim Social Security before the maximum age of 70, leaving thousands of dollars in lifetime income on the table, according to data analyzed by the Center for Retirement Research at Boston College and the NBER. The most popular age to claim is 62, the earliest possible. That choice has a permanent price.
Claiming at 62 instead of your Full Retirement Age (67) permanently reduces your monthly check by 30%. If you claim at 62 instead of waiting until the maximum benefit age of 70, you’re slashing your monthly income by more than 43% compared to what you could have received. That’s locked in for the rest of your life and the life of any surviving spouse who inherits your benefit.
The fix: Before claiming, calculate your break-even age for different scenarios. If you can cover expenses from savings or part-time work in the early retirement years, delaying Social Security is often the highest-return financial decision available.
#4: Carrying Debt Into Retirement Shrinks Your Monthly Income from Day One
The average American household carries $105,444 in total consumer debt (including mortgages), according to Experian. In retirement, those payments don’t disappear. They consume income that would otherwise go toward healthcare, travel, or building a cash buffer.
Debt during working years is manageable because income replaces what goes out. In retirement it’s a different problem. You’re drawing down savings to cover obligations that don’t vary with your portfolio’s performance. In a down market, debt payments stay fixed while account balances fall.
High-interest debt is the most damaging. Credit card debt at 20% compounds in the wrong direction while retirement savings grow at 5–7%.
The fix: Target high-interest debt for elimination while you’re still working. Carrying a mortgage into retirement is a different calculation and may be fine depending on your rate and overall plan. Carrying credit card or personal loan debt is harder to justify once the paychecks stop.
#5: Not Having a Drawdown Strategy Is a Different Problem From Not Having Savings
Accumulating money and spending it down are two different skills. Most retirement planning focuses on the first. Fewer people build the second before they stop working, and it costs them.
A drawdown strategy covers three things. The order you pull from different accounts, which in most cases runs taxable before tax-deferred before Roth. How you’ll generate a guaranteed income floor. And how Roth conversions can reduce your future tax burden before required minimum distributions begin at age 73.
Without a plan, the default is pulling from whatever account is easiest to access. That default is almost never the sequence that minimizes taxes.
The fix: Before retirement, map your income sources: Social Security, any pension, withdrawals from different account types, and any guaranteed income products. Then sequence them with taxes in mind.
#6: Healthcare Costs Before Medicare Are Almost Always Underestimated
Fidelity’s 2025 Retiree Health Care Cost Estimate puts average healthcare costs at $172,500 in after-tax savings for a 65-year-old retiring today. For a couple, the figure is $345,000. Those numbers cover Medicare premiums, supplemental coverage, and out-of-pocket expenses. They don’t include long-term care.
One in five Americans has never thought about healthcare costs in retirement, according to the same Fidelity research. That blind spot shows up as a shock in the first years after leaving work.
The math gets harder for people who retire before 65. You’ll need to cover the stretch before Medicare on your own, through COBRA, a marketplace plan, or a spouse’s employer coverage. Depending on location and coverage level, those costs can run $700 to $1,500 a month or more.
The fix: Build healthcare costs into your retirement budget as a line item, not an afterthought. If you plan to retire before 65, price out marketplace coverage for your area now. A Health Savings Account, if you’re eligible, is one of the most powerful tools available for building a tax-free reserve for future healthcare expenses. The Boldin Planner factors in your healthcare costs for the years before Medicare, when most calculators assume coverage already started.
#7: Long-Term Care Is the Biggest Unplanned Expense in Most Retirement Budgets
About 70% of Americans who reach age 65 will need some form of long-term care, according to the U.S. Department of Health and Human Services. Most retirement plans don’t account for it.
The 2025 CareScout Cost of Care Survey puts the national median for a private nursing home room at $129,575 per year. A semi-private room runs $114,975. Assisted living comes in at $74,400 per year. Home health aide care, the option many people prefer, costs about $77,800 per year based on 44 hours per week.
The average long-term care event lasts two to three years. That’s a potential exposure of $150,000 to $400,000 or more, depending on care type and your location.
The fix: Four ways exist to fund long-term care: personal savings, long-term care insurance, Medicaid after assets are depleted, and hybrid life insurance or annuity products with LTC riders. None of these is right for everyone. The right time to think through the options is now, before you need care. The Boldin Planner lets you model different long-term care funding approaches and see how each affects your overall plan.
#8: Underestimating Longevity Is a Retirement Plan’s Most Common Structural Flaw
A retirement plan built for age 80 can fall short if one partner lives longer. Research from the Society of Actuaries suggests there’s a 50% chance at least one partner in a 65-year-old couple lives to age 92. Planning to the average life expectancy means about half of all couples will outlive their projections.
Running out of money in retirement is a planning failure, and it usually traces back to an assumption made decades earlier.
The fix: Use a life expectancy calculator to get a more informed estimate of your longevity. Then build two scenarios in your plan: one to an optimistic age (95 or 100) and one to a conservative age. If your plan works at 95, you’re covered. If it doesn’t, you know where the problem is before you retire.
#9: Ignoring Taxes in Retirement Can Cost Hundreds of Thousands Over Time
Taxes in retirement come down to three decisions, and getting any one wrong is what turns a manageable bill into one you didn’t have to pay.
The first is Roth conversions. Converting traditional IRA or 401(k) money to Roth before required minimum distributions begin at 73 can cut future taxable income. The window between retirement and RMD age is often the best time for conversions, when income is lower and tax brackets are more favorable.
The second is withdrawal sequencing. Pulling from taxable accounts before tax-deferred accounts before Roth preserves the most tax-advantaged growth over time.
The third is Social Security timing. The more provisional income you have in a given year, the more of your Social Security benefit gets taxed, up to 85%. Keeping IRA withdrawals lower in early retirement can reduce provisional income and protect your benefit.
These three levers interact. Getting them right requires modeling your specific situation, not a rule of thumb.
The fix: Map out a Roth conversion strategy before age 73. The Boldin Planner calculates the tax impact of different withdrawal sequences and Roth conversion amounts, so you can see the actual dollar difference before you convert.
#10: No Emergency Fund Means Retirement Accounts Become the Emergency Fund
According to the Federal Reserve’s 2025 Survey of Household Economics and Decisionmaking, 37% of adults wouldn’t cover a $400 emergency expense using cash or savings. In retirement, that problem is more expensive because the solution carries a higher cost.
When retirees tap retirement accounts for unexpected expenses, the withdrawal triggers ordinary income taxes. Before age 59½, it also triggers a 10% penalty. The original cost can double by the time the tax bill arrives.
A liquid emergency reserve is one of the most direct protections against that chain of events.
The fix: Keep one to two years of living expenses in a high-yield savings account or money market fund. Keep it separate from your investment portfolio. It’s a buffer that prevents forced withdrawals and account raids when life gets expensive.
#11: Emotional Investors Underperform the Market, Year After Year
DALBAR’s annual Quantitative Analysis of Investor Behavior tracks the spread between market returns and what investors take home. That spread runs between one and three percentage points per year. The cause is timing: buying at peaks, selling during drops, waiting too long to re-enter.
Over a 20-year retirement, a one-point annual spread on a $500,000 portfolio is the difference between security and running short. The math is unforgiving.
Emotion isn’t the enemy. Fear and optimism carry real information. Making investment decisions in the moment, when those feelings are loudest, is where things go wrong.
The fix: Build an Investment Policy Statement now, before a downturn. It should specify your target asset allocation, what conditions would trigger a rebalance, and what you’ll do when markets fall 20%. Decisions committed to paper don’t get hijacked by panic.
#12: Overspending in Early Retirement Gets Harder to Reverse the Longer It Continues
The first years of retirement often bring higher spending. Travel, deferred home projects, and finally having time to figure out what to do with retirement all push the budget up. Higher spending in those years is normal. The trouble starts when it isn’t built into the plan.
Morningstar’s retirement income research puts the safe starting withdrawal rate for a 2026 retiree at 3.9% of a balanced portfolio over a 30-year horizon, assuming a 90% probability of not running out. That’s the base case for fixed withdrawals. Flexible strategies can push the number higher, but they require adjusting when markets fall.
Spending 5% or 6% in year one and holding that pace is how a strong portfolio turns into a problem at age 80.
The fix: In the first two years of retirement, track your withdrawals against your plan. Drift caught early corrects without much pain. Drift caught at year five or six often requires harder cuts. The Boldin Planner models your actual spending against your projected withdrawal rate and flags when you’re running ahead of a sustainable pace.
#13: Not Having a Written Retirement Plan Is the Mistake Underneath All the Others
Only 33% of Americans have a written financial plan, according to Charles Schwab’s Modern Wealth Survey. The rest navigate one of the most complex financial periods of their lives on memory and intuition.
A written plan doesn’t need to be a long document. It needs to cover five things: projected income from all sources, the sequence for drawing down accounts, healthcare cost estimates for each decade of retirement, a long-term care funding approach, and an updated estate plan that reflects current wishes.
Without that document, the other 12 mistakes in this list are harder to catch. A budget shortfall, a tax inefficiency, a coverage hole. These show up if you’re tracking the numbers. They’re invisible otherwise.
The fix: Put what you know down on paper now, even if it’s just a page. The Boldin Planner is built for this: one plan that covers income, taxes, healthcare, Social Security timing, and withdrawal sequencing, and updates as your numbers change.
How These 13 Mistakes Compound Each Other
Most retirement planning failures aren’t single errors. They’re chains.
Carrying too much housing expense in your 50s crowds out savings. A savings shortfall means you need income sooner, which pushes toward claiming Social Security early. Claiming early locks in a lower benefit, which means more of your retirement income has to come from portfolio withdrawals. More withdrawals mean more taxes, unless you’ve done Roth conversions. More taxes mean a faster drawdown. A faster drawdown is harder to sustain if you live to 90 or 95. And if a health event hits during that faster drawdown, there’s no cushion.
The interactions run the other direction too. Delaying Social Security to 70 reduces the pressure on your portfolio in your 60s. Less portfolio pressure gives your savings more time to grow. More growth supports a longer retirement with fewer hard choices along the way.
The challenge is that these interactions are hard to see without modeling them. A spreadsheet that projects one variable at a time misses the way they connect. That’s the problem the Boldin Planner was built to solve: one model that shows income, taxes, healthcare, inflation, and longevity working together across 30 or more years.
Frequently Asked Questions
Not claiming Social Security at the right time ranks as one of the most costly retirement decisions Americans make. About 90% of Americans claim at or before full retirement age. Waiting from age 62 to 70 can increase a monthly benefit by 76% or more, depending on birth year. That difference compounds across decades of guaranteed income and can’t be reversed once the claim is filed.
The Federal Reserve’s 2022 Survey of Consumer Finances puts the median retirement account balance for American families at $87,000. Among families approaching retirement, the figure is higher but still falls short of what most financial planners recommend for a 20-to-30-year retirement. A smaller number of households with seven-figure balances pull the mean well above the median, which is why the median gives a clearer picture of what a typical retiree actually has saved.
Three retirement mistakes are hard to reverse once made. Claiming Social Security early is permanent; the reduced benefit doesn’t reset at full retirement age. Not saving enough in your 40s loses compound growth that catch-up contributions in your 50s can’t replace at the same rate. And entering retirement without a healthcare cost plan before Medicare eligibility can force early account withdrawals that carry ordinary income taxes and, before age 59½, a 10% penalty. All three compound without drawing attention until the damage is visible.
Fidelity’s 2025 Retiree Health Care Cost Estimate puts average retirement healthcare costs for a 65-year-old at $172,500 in after-tax savings. For a couple, the estimate is $345,000. Both figures cover Medicare premiums, supplemental coverage, and out-of-pocket costs. Long-term care isn’t included. For the roughly 70% of Americans who’ll need some form of long-term care, that’s a separate and significant expense with its own planning requirements.
Planning mistakes happen before retirement. Not saving enough, claiming Social Security early, and carrying too much debt are decisions made before the last paycheck. Income mistakes happen after retirement. Withdrawing accounts in the wrong order, ignoring taxes on distributions, and spending at a rate the portfolio can’t sustain are patterns that play out over years. Income mistakes are harder to reverse because you’re drawing down a finite pool with no wage income to offset what goes out.
Catch-up contributions are available from age 50. That’s an additional $7,500 per year in a 401(k) above the standard limit. Social Security timing is still flexible for anyone who hasn’t claimed. A detailed financial plan built around your actual numbers, rather than general rules of thumb, often reveals options that aren’t visible at a surface level. The worst mistake at 60 is assuming the window has closed.
