Most people spend decades planning for retirement, but almost nobody plans for what happens inside the first year. There are spreadsheets for the savings target, conversations about when to stop working, maybe even a celebratory trip on the calendar. And then the day arrives, and it turns out that retiring well is a completely different skill from saving well.
The first year is unlike any other. Old routines disappear almost overnight. Money starts flowing in a different direction. Decisions that feel minor in the moment can quietly echo for decades. Experts say the first year of retirement may stand apart from all the others. It can trigger mistakes that snowball, or set the stage for a fulfilling second act. The patterns you establish right now, financially and emotionally, are the ones you’ll be living with for a very long time.
What follows are five of the most consequential mistakes new retirees make, not because they’re careless, but because nobody warned them. If you’re newly retired, close to retiring, or helping someone who is, these are worth reading carefully.
1. Skipping a Spending Plan for the New Reality
Retirement does something quietly disorienting to your finances. You go from depositing money to drawing it down, and without a specific plan for the new reality, that shift can become expensive fast.
A key mindset change in retirement involves moving from earning to figuring out how to draw down from the different account buckets accumulated over a working life, each of which carries different asset characteristics and tax implications. That sounds straightforward, but it catches a lot of people off guard. The habits that served you during your earning years – spend freely because the next paycheck is coming – no longer apply when every dollar you spend is a dollar that can’t grow.
The early years of retirement are often called the “go-go years,” when retirees are most likely to spend on travel, recreation, and bucket-list experiences. According to the 2024 Consumer Expenditure Survey from the Bureau of Labor Statistics, average annual spending for adults aged 65 to 74 runs $65,149. By age 75, that figure drops by nearly 20% to $53,031. Getting too comfortable with that early level of spending can jeopardize savings meant to last for decades.
Common mistakes retirees make when withdrawing funds include not having a diversified portfolio that can withstand market downturns, spending too much so that the portfolio declines or runs out, and failing to plan for required minimum distributions (RMDs). The practical fix is straightforward: track your actual monthly spending for the first three to six months of retirement before making any large financial commitments. Use those real numbers, not pre-retirement estimates, to build a sustainable withdrawal plan.
2. Claiming Social Security Too Early
Few decisions in retirement are as permanent, or as frequently rushed, as when you claim Social Security. The temptation to start collecting at 62 is understandable. You’ve earned it, and the money is right there. But the math on early claiming is genuinely punishing.
Claiming Social Security at 62 reduces your monthly benefit by as much as 30% compared to what you’d receive at full retirement age. Your full retirement age is when you’re eligible to receive 100% of your benefit. Waiting beyond full retirement age increases your benefit by about 8% per year until age 70, and delaying to 70 can increase your monthly payments by up to 24% compared to claiming at full retirement age.
Someone born in 1963 who starts benefits at 62 in 2025 will get as little as 70% of what they’d have received at 67. That reduction is permanent. To put a real number on it, the average Social Security check at age 62 is $1,341.61, which is 37.6% less than the $2,148.12 the average 70-year-old receives.
There’s also the question of long-term totals. If you live long enough, the cumulative benefits from a later, higher-starting claim will eventually surpass the sum of reduced payments you could have drawn earlier. That catch-up moment is called the break-even age. For many people, that break-even point arrives in their late 70s or early 80s, well within a normal life expectancy. The biggest mistake people make isn’t necessarily filing too early or too late. It’s making the decision in a vacuum, without accounting for health, other income sources, a spouse’s benefit, or expected longevity.
3. Keeping the Same Investment Strategy You Used to Build Wealth
The approach that built your nest egg was designed for growth. That made sense when you had 20 or 30 years of contributions ahead of you. But staying in that same posture once you start drawing down is one of the more dangerous things a new retiree can do.
When you retire, your investment strategies will likely change as you shift from accumulation to decumulation. Accumulation means growing assets over time. Decumulation means converting those assets into income while making sure they last. The risks involved are fundamentally different. What makes the early years so critical is something called sequence-of-returns risk. Research from Morningstar found that retirees who encountered poor market conditions in their first five years and failed to scale back spending were far more likely to run out of money than those who made it through the early years with gains.
New retirees who have recently begun taking withdrawals should rebalance to help reduce volatility and support a long-term income strategy that aligns with their financial needs. One framework that financial planners often recommend is the “bucket strategy.” This approach divides savings into three pools by time horizon: a short-term bucket with enough cash to cover two to three years of expenses, a medium-term bucket of bonds with more predictable yields, and a long-term bucket weighted toward stocks. The bucket approach separates spending decisions from market swings. When stocks fall, you draw from cash rather than selling at depressed prices. When markets recover, you replenish the short-term bucket and let equities keep growing.
De-risking a portfolio can get expensive if large moves trigger taxes, so a mindful, gradual transition to a safer portfolio is usually the better approach. For most people, it makes sense to start that transition at least five years before retirement. If you haven’t done it yet, year one is not too late to start.
4. Ignoring the Psychological Side of the Transition
Financial planning for retirement gets most of the attention. Mental and emotional preparation gets almost none. That imbalance shows up quickly in the first year, when the structure that work provided – routine, social contact, purpose, identity – disappears almost simultaneously.
Many people encounter feelings of loss when they retire, particularly of their identity and purpose, which were closely tied to their careers. This shift can lead to depression, anxiety, and grief as individuals adjust to a new phase of life. Social isolation and loneliness are common, especially if retirees don’t actively seek new social connections.
The workplace, it turns out, does a lot of invisible social and psychological work. Social isolation and loneliness are key drivers of depression among older adults. People who get work-related social support are less likely to experience depression, so for these individuals, replacing the work-based network becomes an important step in avoiding isolation and maintaining quality of life in retirement. The most common manifestations of depression in retirement are the absence of a routine and the loss of identity – for many people, work has been the organizing factor in their life.
This isn’t a minor wellness concern. Loneliness can have marked consequences on health via inflammatory responses in the brain, poor sleep quality, and reduced physical activity. Researchers have also linked it to diminished immunity, increased risk of cardiovascular and neurodegenerative diseases, and higher healthcare costs. Replacing work’s social and psychological functions deserves as much attention as replacing work’s income. Engaging in social activities, volunteering, and hobbies are effective ways to boost mental well-being and reduce feelings of social isolation and boredom. Build those structures intentionally in year one, before the absence of routine sets in as a new normal.

5. Treating Year-One Decisions as Low-Stakes
Perhaps the most underestimated mistake of all is assuming that the first year of retirement is a grace period, a time to decompress and figure things out before the “real” planning begins. It isn’t. Many of the decisions made in year one are either irreversible or compound significantly over time.
In the excitement of newfound freedom and a well-stocked nest egg, it’s tempting to splurge, what some financial advisors call the “victory lap phase.” The advice that follows: pause before making any big, irreversible decisions in the first 6 to 12 months. That includes large gifts, home renovations, and claiming Social Security before thinking it through carefully.
The reason early decisions carry such weight comes down to compounding, in reverse. Morningstar’s 2026 retirement income research found that a new retiree planning a 30-year time horizon can safely withdraw 3.9% of a balanced portfolio, while extending the drawdown period to 35 years brings that rate down to 3.5%. On a $1 million portfolio, the difference between those two rates is just $1,000 in year one. But that gap compounds over decades of inflation-adjusted withdrawals and can ultimately determine whether a portfolio holds or falls short.
Tax decisions are similarly consequential from the start. Once you reach age 73, you’re required to take distributions from tax-deferred accounts, and those withdrawals are fully taxable and can push you into a higher tax bracket. Planning ahead with partial withdrawals or Roth conversions can help manage that liability and prevent large jumps in taxable income later on. The time to think about these moves is in your first year of retirement, not the year your first required distribution arrives.

What This Means for You
Retirement is long. It could span a third of your life. That means the habits you form in year one will either serve you for decades or quietly cost you. The good news is that none of the five mistakes above are catastrophic if you catch them early. A budget can be built. A Social Security decision can still be evaluated against your specific circumstances. A portfolio can be rebalanced. Social structures can be built deliberately, and irreversible decisions can simply be slowed down.
What year one really calls for is a clear-eyed reset, treating retirement as a new financial and personal chapter that requires its own planning rather than just the end of the previous one. Take the first few months to track your real spending before committing to a withdrawal rate. Sit down with a financial advisor or use the SSA’s online benefits calculator before filing for Social Security. Rebalance your portfolio to reflect income needs rather than growth targets. And give at least as much thought to your social calendar as you give to your account balances. The retirees who thrive in year two and beyond are almost always the ones who took year one seriously.
