You’ve maxed out contributions when you could, paid off debt early, avoided lifestyle creep. On paper, you’ve done everything right. Then you look closely at a few of your biggest financial decisions and realize some of them have been quietly working against you the whole time.
The median 401(k) balance in America is $44,115, while the number most people picture when they hear “average” is closer to $167,970. That gap isn’t only bad luck or low pay. A lot of it comes down to specific, ordinary-sounding choices that feel careful in the moment and cost real money over the next twenty years.
None of the moves below are exotic or reckless. They’re the responsible-looking decisions that quietly drain tens of thousands of dollars from a retirement account, one reasonable choice at a time.
Cashing out the 401(k) the second you leave a job
You leave a job, HR hands you paperwork, and one box says you can take your 401(k) balance as cash instead of rolling it into a new account. It looks like found money. It isn’t.
Researchers who tracked more than 162,000 workers leaving 28 different retirement plans found that 41.4% cashed out some or all of their retirement savings at job separation instead of rolling the balance forward. Every dollar cashed out gets hit with ordinary income tax, plus a 10% penalty if you’re under 59 and a half. A $30,000 balance can shrink by a third before it ever reaches your bank account.
The fix costs nothing and takes fifteen minutes: roll the balance into your new employer’s plan or an IRA instead of taking the check. You lose nothing by asking your new plan’s administrator to handle the transfer directly, and you keep every dollar working instead of handing a chunk of it to the IRS on your way out the door.
Claiming Social Security the day you turn 62
Sixty-two looks like the finish line, and claiming the moment you’re eligible looks like collecting what you’ve earned. It also locks in a permanently smaller check for the rest of your life.
Full retirement age for anyone born in 1960 or later is 67. Claim at 62 instead, and your benefit is reduced for as long as you receive it, not just for a few years. Wait past 67, and you earn delayed retirement credits worth roughly 8% more for every year you hold off, up until age 70. The average retired worker collected $2,071 a month as of January 2026. That 8% a year compounds into a meaningfully larger check for however long you live.
This isn’t a blanket argument for waiting until 70. Health, other income, and family longevity all matter. It’s an argument for running your own numbers before defaulting to the earliest possible date out of habit.
Skipping catch-up contributions once you hit 50
Turning 50 unlocks extra room in your 401(k) that a lot of people never use, mostly because nobody tells them it exists.
For 2026, workers 50 and older can contribute an extra $8,000 on top of the standard $24,500 limit, bringing the total to $32,500. If you’re between 60 and 63, the IRS lets you go even further with a “super” catch-up of $11,250 instead of the standard $8,000. IRA catch-up contributions rose too, adding $1,100 on top of the $7,500 base limit.
These are your highest-earning, closest-to-retirement years, which makes this room the most valuable stretch of contribution space you’ll ever get. Skipping it isn’t a mistake that shows up immediately. It shows up as a smaller number fifteen years later, after all that unused space has quietly disappeared. Even bumping your contribution rate by a few percentage points the year you turn 50, rather than waiting for a raise or a less busy year, adds up faster than most people expect once compounding has a decade or two to work on it.
Moving your whole portfolio to cash and bonds too early
Getting nervous about the stock market as retirement approaches is a normal instinct. Acting on it by going almost entirely to cash and bonds in your 50s or early 60s tends to backfire.
New 2026 retirement income research found that portfolios holding 30% to 50% in stocks supported the highest safe withdrawal rates, not portfolios that went heavier into bonds and cash. The baseline safe withdrawal rate for that kind of balanced allocation sits at 3.9% for a fixed-spending retiree in 2026. Go too conservative too soon, and you remove the growth engine that’s supposed to keep your money ahead of decades of inflation and withdrawals.
There’s a middle ground between reckless and overly cautious. A retirement that could last 25 or 30 years still needs some exposure to growth, even if the split shifts gradually as you age rather than dropping to near zero the moment you stop working.
Letting required minimum distributions sneak up on you
Required minimum distributions read like a future-you problem until future you is standing in front of a tax bill you didn’t see coming.
Under current rules, you generally have to start withdrawing from traditional IRAs and 401(k)s at age 73, a threshold that climbs to 75 by 2033. Miss the deadline or withdraw too little, and the IRS charges a 25% penalty on the amount you should have taken, cut to 10% if you fix the error within two years. Because RMDs count as ordinary income, a large one can also push you into a higher tax bracket or trigger higher Medicare premiums the same year.
The people who avoid this surprise are the ones who mark the calendar the year they turn 73, not the year the IRS sends a notice. A financial advisor or even a plan administrator can calculate the exact figure well ahead of the deadline.
Buying an annuity without reading the surrender schedule
An annuity salesperson describing guaranteed income for life can sound like exactly what a nervous retiree wants to hear. What often gets skipped is what happens if you need that money back early.
Most fixed and indexed annuities carry surrender charges that start around 10% and shrink to zero over a schedule that can run six to eight years. Pull money out before then, and that percentage comes straight off the top, on top of a 10% IRS penalty if you’re under 59 and a half. Variable annuities add another layer of ongoing fees for mortality, expense, and administrative costs that keep charging every year you hold the contract.
Annuities aren’t automatically a bad product. They’re a bad fit for money you might need access to. Before signing anything, ask specifically how much you’d lose if you needed the funds back in year two, not year ten, and get the answer in writing rather than a verbal estimate from whoever is selling you the contract.
Treating whole life insurance as your investment plan
An insurance agent pitching a policy that “pays a death benefit and builds cash value” is describing two different products stapled together, and the investment half is the weaker one.
The average annual return on whole life cash value runs between 1% and 3.5%, well below what a low-cost index fund has delivered over most stretches of market history. It also takes 10 to 15 years before the policy builds enough cash value to be worth borrowing against, because early premiums go mostly toward fees and commissions rather than your account balance.
Whole life can make sense for specific estate planning needs or a lifelong dependent who requires ongoing financial support. It rarely makes sense as your main retirement growth vehicle, and premiums that could have gone into a 401(k) or IRA usually would have worked harder there. If an agent frames a policy primarily as a savings or investment tool rather than as insurance, that’s a signal to get a second opinion before you commit to years of premiums.
Draining a retirement account to pay off the mortgage
Being debt-free looks like the responsible endgame, and pulling a lump sum from a 401(k) to zero out the mortgage balance can look like the fastest route there. The bill for that decision is bigger than most people expect.
Withdraw $50,000 from a 401(k) before age 59 and a half, and you’ll automatically owe a $5,000 penalty before taxes are even calculated. On a $100,000 withdrawal taxed at a 24% federal rate plus the 10% penalty, you could lose $34,000 to the IRS and keep just $66,000 of it. That’s money that also stops compounding for whatever years remain before retirement.
If a mortgage payment actually threatens your monthly budget, refinancing, downsizing, or using non-retirement savings first usually costs less than raiding a tax-advantaged account that’s still supposed to be growing. The emotional relief of a paid-off house is real, but it’s worth pricing out against the tax bill and lost growth before deciding it’s worth the trade.
Forgetting Medicare premiums scale with your income
Medicare Part B has a standard premium everyone assumes they’ll pay, until a bigger number shows up on the bill because of income from two years earlier.
The 2026 standard Part B premium is $202.90 a month, but income-related monthly adjustments kick in for anyone whose 2024 income topped $109,000 for single filers or $218,000 for joint filers, pushing the monthly premium as high as $689.90. Because Medicare uses a two-year lookback, a big Roth conversion or a large capital gain today can raise your premiums in a year you’re not expecting it.
This is exactly why RMDs, Roth conversions, and capital gains need to be planned with Medicare in mind, not decided in isolation. A withdrawal that looks smart on a tax return can quietly cost you thousands in higher premiums two years down the road, for a full year, since these adjustments reset annually rather than phasing in gradually.
Retiring with a credit card balance still open
Retirement doesn’t erase existing debt, and a surprising number of retirees find that out the hard way once fixed income meets revolving interest.
A recent analysis found that 92.6% of retirement-age adults carry a credit card balance, with average APRs sitting around 21% in 2026. The 2026 Social Security cost-of-living increase came in at just 2.8%. A fixed benefit growing under 3% a year cannot outrun revolving debt priced at seven times that rate, no matter how disciplined your monthly budget is otherwise.
Paying that balance down before you retire, even if it means working a few extra months, does more for your financial security than almost any investment decision you could make in that same window. Interest at 21% is a guaranteed loss that no market return reliably beats, and treating a payoff plan as part of your retirement timeline, not a separate problem to deal with later, tends to produce a much calmer first year of retirement.
Sending your adult kids more than your own 401(k)
Helping your kids looks like the obvious right choice, month after month, until you add up how much of your own retirement you’ve quietly redirected to theirs.
Roughly 75% of parents give some form of financial support to at least one adult child, and working parents contribute about 2.3 times more each month to their kids than to their own retirement accounts. Groceries, phone bills, and vacations add up quietly because each individual expense feels small and temporary, even as the combined total quietly outpaces what’s going into your own accounts.
Helping isn’t the problem. Helping without a ceiling is. A monthly dollar limit, tied to what you can afford after your own retirement contributions are funded, keeps generosity from becoming the reason you’re still working at 72. Framing the help as a fixed, temporary amount rather than an open-ended arrangement also tends to protect the relationship, since neither side has to renegotiate the terms every time a new expense comes up.
Never touching Roth conversions before RMDs hit
A traditional IRA that’s grown for thirty years turns into a tax bill the government eventually forces you to take, whether or not you actually need the income that year.
Converting some of that balance to a Roth IRA during lower-income years, ideally before required minimum distributions start at 73, means paying tax on the conversion now at a rate you control, rather than later at a rate the IRS controls through forced withdrawals. Advisors who work through retirement income planning often flag the years right after you stop working and before Social Security or RMDs begin as the cheapest window to convert, since taxable income tends to dip during that gap.
This isn’t a strategy to run without guidance. Converting too much in one year can itself trigger a higher tax bracket or Medicare surcharge. Converting nothing at all just guarantees the IRS decides your tax bill for you later.
Co-signing your kid’s loan
Co-signing looks like a formality, a signature that helps your child get approved without really costing you anything as long as they keep paying. That assumption doesn’t hold up well in practice.
About 90% of private student loans require a co-signer, and a survey of 500 parent co-signers found that 56.8% believe their credit score has been hurt by cosigning, while 51.2% said their child’s debt was putting their own retirement in jeopardy. You’re not a backup plan when you co-sign. You’re equally responsible for the full balance from day one, and a lender has no obligation to warn you before your child’s late payment shows up on your credit report.
If you’re financially able to make the payments yourself without hardship, co-signing carries less risk. If you’re not, a smaller amount you’re prepared to give outright is usually safer than a signature obligating you to an amount you can’t control.
Treating the 4% rule like a law of physics
The 4% rule has been repeated so often it gets treated as settled fact, when the research behind it keeps shifting the number and the assumptions underneath it.
The newest retirement income research sets a baseline safe withdrawal rate at 3.9% for a fixed-spending retiree in 2026, rising to as high as 5.7% for retirees willing to adjust spending based on how markets perform. Even Bill Bengen, the researcher who created the original 4% rule in 1994, has since revised his own worst-case estimate up to 4.7%. Three credible numbers, three different assumptions, and none of them is a fixed rule that applies to every portfolio.
What matters more than memorizing a single percentage is understanding which assumptions apply to your situation, including your asset mix, how flexible your spending can be, and how much guaranteed income you already have from Social Security or a pension. Treat any single number as a starting point for a conversation with an advisor, not a fixed rule you can set and forget for thirty years.
Sitting on a mountain of cash “just in case”
An emergency fund is smart. Treating half your net worth like an emergency fund is a different decision entirely, and it has a real cost that doesn’t show up on a bank statement.
A retiree holding $100,000 in cash loses roughly $25,770 in purchasing power over ten years at 3% inflation, even while the account balance itself never drops. The interest a savings account pays rarely makes up the difference once you account for taxes on that interest. The balance on your statement stays the same. What it actually buys keeps shrinking.
Most planners suggest 12 to 24 months of expenses in cash or short-term CDs, with the rest invested in something that has a realistic shot at outpacing inflation over the decades a retirement can last. Safety and stagnation aren’t the same thing, even though they can look identical on a balance sheet, and the retirees who confuse the two often don’t notice until their spending power has already slipped.
Bottom line
There’s one more detail worth knowing before you write off early withdrawals entirely: if you leave a job the year you turn 55 or later, the IRS’s rule of 55 lets you pull from that specific employer’s 401(k) penalty-free, though income tax still applies. It only covers the plan tied to the job you just left, not old accounts or IRAs, and it’s easy to miss if nobody mentions it.
None of this requires perfection. It just takes a five-minute check before you cash something out, sign a loan, or claim a benefit you can’t take back.
