The first twelve months of retirement feel like a reward. Decades of saving, planning, and waiting have finally paid off. But this is also, quietly, one of the most financially fragile periods of a person’s life. Decisions made in year one often lock in patterns, deplete buffers, or trigger irreversible consequences that compound over the decades that follow.
Financial advisors who work closely with newly retired clients tend to notice the same patterns repeating. Not dramatic blunders, usually, but quieter miscalculations that feel harmless in the moment and become very costly later. Here are the nine mistakes they see most often – and why recovery is so difficult once they take hold.
1. Claiming Social Security Too Early Without a Real Plan

Applying for Social Security at 62 is allowed, but the benefit received will be up to 30% less than it would be at full retirement age as defined by the Social Security Administration. That’s a permanent reduction, not a temporary one. Assuming a full benefit of $1,783 per month at full retirement age, claiming at 62 instead would drop that figure by roughly 30% to $1,248 – a loss of about $6,420 per year.
Delaying the application until age 70 results in a benefit that is about 32% higher than it would be at full retirement age. Most people who claim early do so because the money feels useful right now, without fully calculating how much they’re giving up over a 20 or 30-year retirement. The math almost always favors patience for those in reasonably good health.
2. Ignoring Sequence of Returns Risk in Year One

Sequence of returns risk is the danger that poor investment returns early in retirement, combined with ongoing withdrawals, will significantly reduce a portfolio’s value and limit its ability to recover. Early losses are especially damaging because withdrawals during a downturn lock in those losses, leaving less capital to recover when markets rebound.
Research by Wade Pfau, Ph.D., CFA, a professor of retirement income at The American College of Financial Services, has directly quantified the impact: the compounded return in the first ten years of retirement accounts for about 77% of the final retirement outcome. In a modeled scenario, a portfolio hit by a 15% decline in the first two years was fully depleted after 17 years, while an identical portfolio that experienced the same decline later still held over $100,000 after two decades. The first year isn’t just the beginning – it can define everything that follows.
3. Overspending Early Because "It's Finally Time"

Retirement has phases, and the early years tend to be expensive ones. Retirees are healthy, energetic, and finally have the time to pursue things they’ve been putting off – travel, hobbies, home projects, helping the grandkids. None of that is wrong. The problem is that early retirement spending can set a pace that simply isn’t sustainable for a 25 or 30-year retirement.
Retirement savings can look like a large number, but retirees must keep in mind that the money will have to last a very long time. Avoiding the temptation to spend large chunks of the nest egg early in retirement is essential. Advisors consistently see clients who spent freely in their 60s without fully accounting for what their 70s and 80s would cost, particularly as healthcare needs increase and income sources become less flexible.
4. Failing to Build a Written, Stress-Tested Income Plan

It’s common for people approaching retirement to have a general sense of their plan without ever committing it to paper. They may have a rough idea of when they want to retire, what they expect to spend, and what they assume Social Security will cover – but without a written plan, these assumptions are rarely stress-tested and they’re often wrong.
According to the Social Security Administration, most financial advisors recommend having 80% of pre-retirement income to live comfortably in retirement. Social Security, by design, replaces only around 40% of pre-retirement income for an average earner, meaning the gap must come from personal savings, investments, and other income sources. Saving without a defined retirement age, income goal, or spending estimate can lead to significant gaps in your planning.
5. Drastically Underestimating Healthcare Costs

According to the 2026 Milliman Retiree Health Cost Index, the average healthy 65-year-old couple retiring this year is projected to spend up to $637,000 on healthcare expenses over the course of their remaining lifetimes, driven by higher Medigap and Medicare Part B premiums along with projected growth in long-term healthcare inflation. That figure routinely shocks new retirees who assumed Medicare would cover most of the bill.
Health-related cost inflation is projected to rise by 5.8% over the long term, more than double the 2.8% Social Security cost-of-living adjustment for 2026. The first few years of retirement are often the cheapest from a healthcare perspective, and a healthy 65-year-old might spend $5,000 to $7,000 annually on premiums, deductibles, and out-of-pocket costs – which initially feels manageable. The challenge is that healthcare spending does not stay at that level, climbing at a rate that outpaces both general inflation and most retirees’ income growth.
6. Withdrawing From Accounts in the Wrong Order

Failing to consider the tax impact of retirement withdrawals is a common mistake. Different types of accounts – like Roth IRAs, traditional IRAs, and 401(k)s – are taxed differently. Strategic withdrawals and understanding how taxes affect your income can help you preserve more of your savings. Getting the sequence wrong in year one can trigger a higher tax bracket that affects future years and reduces lifetime income.
Households that save without much thought to diversifying retirement assets across different types of financial accounts face real challenges, even when they’ve amassed an adequate nest egg. Many retirees have everything concentrated in tax-deferred accounts, leaving them with no tax-free income option and no flexibility when the IRS comes calling. The first year of withdrawals often sets the pattern – for better or worse – for the years that follow.
7. Reacting Emotionally to Market Volatility

Some of the best single days in market performance come shortly after some of the worst. Investors who sell during a downturn lock in their losses and can miss the recovery that follows. For someone already in retirement, the instinct to protect what they’ve built by moving to safety can feel completely rational in the moment – but the data suggests otherwise.
The retirement red zone refers to the five years before and after retirement, the period when a major market downturn can do the most lasting damage, because there is less time to recover and assets may be drawn down simultaneously. A practical strategy to guard against this is maintaining 12 to 24 months of living expenses in cash or cash equivalents within the overall portfolio, which allows retirees to cover expenses during a market downturn without being forced to sell investments at a loss.

Parents in their first years of retirement sometimes drain savings, co-sign loans, or keep funding grown kids’ lifestyles, reasoning that they can catch up later. The problem is that children have decades to recover from a financial setback, while retirees do not. You can borrow for almost anything – except retirement.
The critical principle is that you cannot effectively provide for others in retirement if you have not first secured your own financial foundation – there is a reason airline safety instructions tell you to put on your own oxygen mask before helping others. Unless you are certain you have the money to spare, avoid giving large monetary gifts or loans after retirement. Generosity is admirable, but it needs to be planned and budgeted rather than reactive.
9. Carrying Too Much or Too Little Investment Risk

When saving for retirement, investors could afford to invest more aggressively because time was on their side to recoup any losses. As retirement begins, the calculus changes – assets are now needed for day-to-day expenses, which may cost more due to inflation, and the luxury of time no longer exists. Yet many retirees and pre-retirees believe their portfolios are more conservative than they actually are.
Carrying too much stock risk right before and after retirement, or alternatively fleeing entirely to cash and missing growth, are both portfolio mistakes with lasting consequences. Adopting a more conservative investment strategy as you get older is generally advisable, with equity holdings ideally decreasing over time – the aim being to reduce risk, which becomes increasingly important as there may be no luxury of awaiting a market bounce-back following a downturn. Getting this balance wrong in year one often means either too much exposure to a bad market or too little growth to sustain a 30-year retirement.
The first year of retirement is genuinely exciting. It should be. The challenge is that excitement and urgency don’t mix well with financial discipline. Most of the mistakes on this list aren’t reckless – they’re human. They come from optimism, generosity, anxiety, and a natural desire to finally enjoy what you’ve worked for. Knowing where the traps are doesn’t take the joy out of retirement. It keeps the joy sustainable.
