The 5 Retirement Mistakes I See People Make Over and Over
Many people believe that retirement is all about how much money they’ve managed to save.
Saving is important. Still, most of my clients have spent 30 years steadily contributing to retirement accounts, yet they face choices that can quietly reduce what they’ve built.
The good news is that most retirement mistakes can be avoided once you know what to watch out for.
If you plan to retire in 5 to 10 years and most of your savings are in a pre-tax 401(k) or IRA, these are the issues to focus on. This is where I often see people leave the most money on the table, since the balances are big enough for these decisions to really matter, and there’s still time to act.
Imagine this scenario
Think of a couple in their early 60s who have done the hard work. They’ve both had steady careers, paid off their house, and most of their savings are in his 401(k) and her IRA. On paper, everything looks set.
But then the questions begin. Should they start Social Security at 62 or wait? What happens to their accounts between their last paycheck and when withdrawals are required? Their investments haven’t been updated since their 40s. They can’t remember what their beneficiary forms say. And no one has checked the cost of health coverage before Medicare starts.
None of these issues feel urgent, which is why people often put them off. These decisions don’t demand attention right away, but the cost of ignoring them can show up years down the road.
Mistake 1: Claiming Social Security at 62 just because you can
Many people turn 62 and think, ‘I’ve worked my whole life, so it’s time to start collecting.’ That feeling is understandable.
But this is where problems can start. People often take Social Security as soon as it’s available, without comparing it to other options. Someone might file at 62 without checking what their benefit would be at full retirement age or at 70.
Filing early can mean locking in a lower monthly benefit for life. If you’re married, there’s another factor to consider. When one spouse passes away, the survivor usually keeps the higher of the two benefits, not both. So, the higher earner’s claiming age affects not just their own check, but also the minimum benefit for whoever lives longer.
This doesn’t mean everyone should wait until 70. It just means you shouldn’t make the decision without understanding the tradeoffs.
Before you file, get your actual benefit estimates for age 62, full retirement age, and 70 from ssa.gov. Compare those numbers to your expected expenses and other income sources.
Mistake 2: Doing nothing in the years between retiring and age 75
This is the point I want you to really consider, because it’s the time when someone with a large pre-tax balance has the most flexibility.
Picture someone who retires at 65. The paycheck stops. They delay Social Security. Required minimum distributions haven’t started yet, and if you were born in 1960 or later, those begin at 75.
For many people, these years are actually the lowest-income period of their adult lives.
This is where mistakes happen. People often assume these middle years don’t need much attention and just go on autopilot. They don’t check future tax brackets, estimate how big their distributions will get, or consider if Roth conversions make sense while their tax rate is low.
Then age 75 comes. Distributions start on an account that’s been growing for years. Social Security may already be coming in. The tax situation now looks very different from what it did at 66.
You might spend your lowest-tax years without taking advantage of them, only to face a bigger tax bill later that could have been reduced.
Plan out your income for each year from retirement to age 75. Where will your money come from each year? What will your tax bracket be? How big will your distributions get if you leave the balance untouched?
Most people spend decades planning how to save, but very little time planning how to withdraw. For someone with a large pre-tax balance, that lack of planning can be costly.
Mistake 3: Keeping the same investment strategy you had 20 years ago
The strategy that helped you save money may not be the best one for retirement. At 40, you had decades before you needed those funds. That’s no longer the case.
This can go wrong in two different ways.
Some people never review their investment mix. For example, someone at 63, planning to retire soon, might have their 401(k) invested just like it was at 40. Others do the opposite. When retirement gets close, they get nervous and move everything to cash.
Both situations need a closer look. You might be taking on more risk than you realize, which can hurt if the market drops while you’re withdrawing money. Or you might be too conservative, and your money could lose buying power over a retirement that lasts 30 years.
Check your investment mix at least once a year and ask yourself three questions: When will I need each part of this money? How much of my income will come from these accounts? Has my comfort with risk changed as retirement gets closer?
Retirement planning isn’t just about growing your money. It’s about making sure your investments match your current stage of life.
Mistake 4: Forgetting that beneficiary forms often matter more than your will
This mistake is easy to make because everything seems fine until it’s too late.
Each of your retirement accounts and life insurance policies has a beneficiary form. This form tells the company who gets the money, and in many cases, it overrides your will.
Here’s where things can go wrong. People fill out the form once and never check it again. Life changes: marriages, divorces, kids growing up, grandchildren being born, or rolling a 401(k) into an IRA where the new account has no beneficiary listed.
Imagine someone who divorced, remarried, and updated their will. But their IRA beneficiary form still lists the former spouse. The will says one thing, but the account says another, and the account usually takes priority.
Assets can end up with someone you didn’t intend, leaving your family confused and facing extra costs at a difficult time, all because of something a quick review could have fixed. Then open each one and read what the beneficiary line actually says right now. Not what you remember choosing. What it says today. Check your contingent beneficiaries while you’re in there.
Mistake 5: Retiring without a plan for health care costs
Many people think Medicare will cover most of their health costs, but it usually doesn’t cover as much as they expect.
This is where problems start. People don’t check what Medicare actually covers until after they retire, so they don’t know where the gaps are.
Medicare usually doesn’t cover routine dental care, vision exams, or hearing aids. It also doesn’t pay for long-term care, like help with daily activities at home or in a facility.
If you plan to retire before 65, you’ll need to pay for your own health insurance until Medicare begins. This can be one of the biggest expenses in early retirement, and it often determines whether your planned retirement date is realistic.
One unexpected health event can create a big expense you didn’t plan for, and it will come straight out of the savings you spent decades building.
Before you retire, review what each part of Medicare covers. Think about whether a supplemental policy, like Medigap, is right for you. Also, consider how you’d handle long-term care needs, whether through insurance or savings, before you actually need it.
When we meet with someone going through this process, the hardest part usually isn’t the math. It’s how many basic questions still don’t have clear answers.
- Have you pulled your actual Social Security estimates, or are you working from a rough idea?
- If the higher earner claims early, what does that do to the survivor’s income later?
- What does your tax bracket look like in each year between your retirement date and 75?
- How large do your required distributions get if that balance keeps growing untouched?
- When did you last read the beneficiary line on each of your accounts?
- If you retire before 65, what will health coverage cost you until Medicare starts?
If these questions are tough to answer, that’s completely normal. Most people don’t know these answers right away.
What these retirement mistakes have in common
There’s a pattern in all five mistakes. None of them are about predicting the market or picking the perfect investment. Each one is a decision that often gets overlooked, not a market you have to outsmart.
That’s actually good news, because you can still do something about overlooked decisions.
This is the kind of work we help with. We begin by looking at what you’ll actually spend and where your income will come from. We plan out the years between your retirement date and age 75 to make the most of your lower tax brackets. We also look at how your claiming decisions, withdrawals, and tax planning all fit together, instead of treating them separately. For tax details, we work with your CPA, and for anything legal, we coordinate with your attorney.
Feeling confident about retirement comes from having clarity, not just hope.
