7 Expensive Money Errors to Avoid in Your First Year of Retirement

Digilifetrends Updated 2026-10-27 3 min read

Many workers spend years contributing to a 401(k) or similar retirement plan, but leaving the job does not mean the planning is over. Making sure your savings last through retirement requires time, discipline, and careful decisions about how to use your money.

These are some of the most common mistakes people make during their first year after retirement begins.

Spending too freely and taking out too much at the start

The moment retirement begins can feel liberating, but one of the costliest mistakes is going overboard early on. Some retirees draw too heavily from their 401(k) to fund travel, home improvements, or a new car. Taking out too much too soon can reduce long-term growth and strain your portfolio for years. A better approach is to map out withdrawals carefully. Many financial professionals point to the 4% rule as a guide.

Facing a tax bill that is larger than expected

Another common error is underestimating taxes. During working years, taxes are usually withheld automatically, which makes them easier to predict. In retirement, however, large withdrawals or missing a required minimum distribution deadline can create problems. The required minimum distribution age is now 73, not 72. A tax professional can help retirees avoid missed deadlines and other mistakes that may increase future tax obligations.

Miscalculating healthcare costs or missing Medicare enrollment

Many people assume healthcare spending will fall in retirement because Medicare becomes available. Yet a recent Fidelity report found that retirees spend an average of $185,500 out of pocket on healthcare. Those expenses can be unpredictable, so setting aside dedicated money for medical needs can help. It is also important not to miss Medicare enrollment, since failing to sign up on time can lead to penalties. Setting reminders for key enrollment deadlines can prevent costly oversights.

Failing to keep cash available for a market downturn

Without a cash cushion, retirees may end up relying on credit cards or tapping retirement accounts during a market slump. Keeping cash on hand can help cover unexpected costs, whether it is an emergency room visit or a major home repair. If withdrawing from retirement savings is the only option, there is a risk of taking out too much at the wrong time. In the first year of retirement, a market downturn can create sequence-of-returns risk, where early withdrawals can hurt portfolio performance for decades.

Not learning how the different retirement accounts work

Some retirees do not take enough time to understand the differences among retirement accounts. For instance, many people use the early years of retirement, when income is lower, to complete a Roth conversion. Whether that makes sense depends on an individual’s financial picture and retirement income. Without a clear understanding of traditional and Roth accounts, a retiree could miss an important conversion opportunity early in retirement.

Moving or buying a vacation home before settling into retirement

Retirement is a major life transition, and it can take time to adjust from a paycheck to a fixed income. Some people make major financial decisions, such as relocating or purchasing a vacation home, before they have really settled into their new routine. Using the first year to see what retirement is actually like can help before making a big move or taking on a large new asset.

Not being emotionally ready for retirement

Financial readiness is important, but emotional readiness matters too. Retirement is a major new chapter, similar to other big life changes such as marriage or starting college, and it often requires an adjustment period. Working with a financial advisor can help with withdrawal planning, the timing of required minimum distributions, and decisions about larger purchases, making the first year of retirement easier to manage.

Bottom line

When people are younger, financial mistakes may feel easier to recover from because there is more time to correct them. But the first year of retirement is especially important, both financially and personally. Building a plan early, keeping close track of spending, and seeking advice when needed can help retirees avoid costly missteps.
