Retirement planning is mostly about managing a transition. For decades the focus is accumulation. The real test starts when the paychecks stop and the withdrawals begin.
A lot of consequential decisions get made in that window, and many of them get made on outdated advice, on emotion, or without much awareness of what things actually cost. For most people this is a learn-as-you-go process, which is a hard way to learn something you only do once.
The awkward part is the delay. A misstep in your 50s or 60s often doesn't show its full effect until your 70s or 80s, by which point fixing it is much harder and sometimes impossible.
What follows are the mistakes that do the most damage, and what to do instead.
Why Retirement Plans Fail
Three reasons account for most of it:
Underestimating expenses. People assume costs drop. Commuting and the work wardrobe do go away. Healthcare and leisure move straight into the gap, and often more than fill it.
Ignoring inflation and longevity. A plan that looks fine today can look very different after twenty years of compounding inflation, especially if you outlive the life expectancy you planned around.
Reactive decisions. Panic-selling in a downturn, claiming Social Security early out of anxiety. Emotional choices are where long-term security usually goes.
1. Retiring Without a Written Drawdown Strategy
Going from saving to spending needs a different skill set than the one that got you here. You spent thirty years accumulating. Now the question is distribution, and almost nobody has practiced it.
Without a plan, the default is to pull from whatever's easiest to reach: checking, then savings, then the traditional IRA or 401(k). That sequence nearly guarantees you pay more tax than you had to.
A real drawdown plan sets the order across taxable, tax-deferred and tax-free accounts to minimize lifetime tax and manage Required Minimum Distributions. It also builds an income floor for essential spending, so you're never forced to sell equities in a bad month to cover the electric bill.
What to do instead
Map your income streams before you retire, not after. Set the withdrawal sequence deliberately. Look hard at Roth conversions during the low-income years between retiring and the start of RMDs. Those are usually the cheapest tax years you'll ever have, and the Roth conversion calculator will show you the shape of it. The retirement income calculator will lay out the sources side by side.
2. Misjudging Healthcare and Long-Term Care
Assuming Medicare covers everything is the most expensive myth in retirement planning.
Fidelity's Retiree Health Care Cost Estimate puts the figure at roughly $185,500 in after-tax savings for a 65-year-old retiring in 2026. Fidelity publishes a per-person number only, so a couple should plan on roughly double. That covers Medicare premiums, co-pays and out-of-pocket prescriptions. It explicitly excludes long-term care.
Long-term care is the bigger exposure. The CareScout (Genworth) Cost of Care Survey puts the national median for a private nursing home room at $355 a day, roughly $129,575 a year. A non-medical home health aide runs a median $35 an hour, about $80,080 a year at 44 hours a week.
Medicare generally doesn't pay for custodial care, meaning help with bathing, dressing and eating, which is the majority of what long-term care actually is. Those costs come out of pocket until assets are depleted far enough to qualify for Medicaid.
What to do instead
Treat healthcare as a fixed line item in the budget. Max out an HSA while you're still working if you're eligible, since those funds come out tax-free for medical costs later. For long-term care, decide early between traditional insurance, a hybrid policy, or deliberately earmarking part of the portfolio to self-fund. Size both exposures with the healthcare cost and long-term care calculators before you choose.
3. Claiming Social Security Too Early
This is the largest irreversible financial decision most retirees make. You can claim at 62. Doing so cuts your monthly benefit permanently.
If your full retirement age is 67, claiming at 62 reduces the check by 30%. Every year you wait past FRA up to 70 adds roughly 8%. Going from 62 to 70 can lift the monthly amount by more than 75%, according to the SSA.
Despite that math, data from the Center for Retirement Research at Boston College puts the average retirement age at about 65 for men and 63 for women, and many people claim the moment they stop working. Poor health or job loss forces the decision sometimes. Claiming early just because the money is available leaves a great deal on the table across a long retirement.
What to do instead
Work out your break-even age, the point where the cumulative value of delaying overtakes claiming early. If you have savings to bridge from retirement to 70, delaying is the most effective longevity hedge available to you, because it buys a higher inflation-adjusted income for life. The claiming age calculator compares 62, 67 and 70 in today's dollars.
4. Carrying Consumer Debt Into Retirement
A mortgage is a nuanced call. If the rate is low and your investments return more, keeping it can make sense. High-interest consumer debt is not nuanced. It's simply bad for a retirement plan.
The Federal Reserve's Survey of Consumer Finances shows a meaningful share of older Americans carrying debt into retirement. On a fixed income, debt payments are a rigid cost that doesn't flex when markets do. In a downturn you can end up liquidating depreciated assets to service a credit card, which accelerates exactly the depletion you were trying to avoid.
What to do instead
Attack it in the red zone, the five to ten years before you stop. Clear revolving credit first. Entering retirement debt-free lowers your baseline income requirement, and that single change buys more flexibility than almost any portfolio decision you could make instead.
5. Benchmarking Against Averages
It's easy to look at a national average and feel fine. The Federal Reserve's 2022 Survey of Consumer Finances reported average retirement account balances of $537,560 for households aged 55 to 64.
Averages are dragged upward by extreme wealth at the top. The median for the same group was $185,000. Across a retirement of 25 to 30 years, $185,000 doesn't sustain most middle-class lifestyles, and the gap between those two numbers is the reason so many people feel more prepared than they are.
What to do instead
Benchmark against your own projected expenses, not the country's. If you're behind, use catch-up contributions. Per IRS limits for 2026: A financial readiness check is the quickest way to see which of these gaps is actually yours.
Employee deferral limit: $24,500.
Standard catch-up at 50 and over: $8,000.
Super catch-up under SECURE 2.0 for workers turning 60, 61, 62 or 63: $11,250.
Total annual additions across employee and employer contributions: $72,000 before catch-ups.
Then check the real question, which isn't the balance but how long it lasts. The savings longevity calculator answers it directly.
6. Underestimating How Long You Will Live
Planning your money to age 85 feels conservative, and it is closer to a coin flip than most people realise. For a couple aged 65 today, SSA's period life tables put the chance that at least one of you reaches 90 at roughly even, and better than that if you are both in good health.
Build around average life expectancy and you're essentially flipping a coin on whether you outlive your money.
What to do instead
Stress-test to 95, and run it to 100 if you have family history to justify it. Leaving a larger inheritance than you planned is a far better failure mode than spending your last decade on a stretched Social Security check. The longevity calculator gives you a range rather than a single number, which is the more honest way to plan it. If leaving something behind is part of the point, decide that deliberately as part of your legacy plan rather than letting it fall out of an over-cautious withdrawal rate.
7. Planning the Money and Nothing Else
This one rarely appears on lists like this, and it's the mistake people regret most.
Every error above is financial, and all of them are fixable with arithmetic and discipline. The one that isn't financial is arriving at a fully funded retirement with no idea what you'll do on a Tuesday. Money buys the option. It doesn't tell you what the option is for.
A retirement that works rests on five things, not one: Finance, Health, Purpose, Connections and Legacy. Most people reading an article about retirement mistakes score well on the first two and have never assessed the other three. That asymmetry doesn't show up in any projection, and it's the most common reason a well-funded retirement still feels wrong six months in.
What to do instead
Score all five honestly, then work on the weakest rather than the most comfortable. Pick your focus area and start there.
Sequence of Returns: The Risk That Actually Ends Plans
Consider retiring into a year when equities fall sharply and inflation runs hot. With no cash reserve, you're withdrawing from a declining portfolio to cover living costs, which permanently locks in those losses. The same average return, arriving in a different order, produces a completely different outcome.
That's sequence-of-returns risk, and it's why two people with identical portfolios and identical long-run returns can end up in very different places purely because of when they retired.
The defense is unglamorous. Hold one to two years of living expenses in cash or short-term Treasuries and spend from that during a drawdown, giving the equity portfolio time to recover. It costs you a little return in good years, and it keeps a bad first year from becoming a permanent impairment. Test your assumptions with the safe withdrawal rate calculator before you settle on a spending number.
Frequently Asked Questions
What is the 4% rule, and does it still hold?
It suggests withdrawing 4% of your initial portfolio, adjusted annually for inflation, over 30 years. It's a reasonable starting point. Most planners now favor a dynamic rate that responds to market performance rather than a fixed percentage held regardless of conditions.
Should I stop investing in stocks once I retire?
No. Moving entirely to cash or bonds trades market risk for inflation risk over a 20 to 30 year horizon, and inflation is the one that compounds against you. Keep enough conservative assets for near-term spending and let equities grow untouched for the later years.
Does Medicare pay for nursing homes?
Generally, no. Medicare covers medical care: hospital stays, doctor visits, short-term rehabilitation. It doesn't cover custodial care, which is help with bathing, dressing and eating, and that's the bulk of long-term care and nursing home cost.
How much should I have saved by 65?
There's no universal figure, and any number quoted without your expenses attached is noise. Work backwards from your projected annual spending, subtract Social Security and any pension, and size the portfolio to cover the remainder for 30 years.
Is it too late to fix this if I'm already retired?
Several of these stay open after you retire. Withdrawal order, the cash buffer, Roth conversions before RMDs begin, and long-term care planning are all still live. The Social Security claiming decision is the one that mostly closes behind you.
The Common Thread
Retirement needs managing and correcting as you go.
Every mistake here shares a root: an assumption standing in for data, or a default standing in for a decision. Track what you actually spend, choose your claiming age deliberately, budget healthcare like the fixed cost it is, and plan for a longer life than you expect. None of that is complicated. It's just easier to skip.
