Most people spend decades preparing for retirement. They save. They invest. They contribute to their 401(k). They calculate how much they will need and eventually reach the point where they believe they can finally stop working.
Then retirement begins. And so does one of the most important periods in the entire retirement plan.
The first five years.
These early years can have an meaningful impact on how long your money lasts. Not necessarily because retirees suddenly make bad decisions, but because several important financial changes can happen at once.
Your paycheck stops. Withdrawals begin. Taxes change. Healthcare changes. Social Security decisions need to be made. And your investment portfolio goes from something you have spent decades contributing to, to something you may now depend on for income.
That transition deserves more attention than it often gets. Especially because it may happen sooner than you expect.
According to the Employee Benefit Research Institute’s (EBRI) 2026 Retirement Confidence Survey, workers expect to retire at a median age of 65. Retirees, however, reported a median retirement age of 62, and nearly half said they retired earlier than planned.
Three years may not sound like much. But three fewer years of saving combined with three additional years that your retirement assets may need to support you can meaningfully change a retirement plan.
The Same Market Decline Can Have A Very Different Impact
Consider two retirees with identical portfolios and identical long-term investment returns. One experiences a major market decline during the first few years of retirement. The other experiences it much later.
Their outcomes can be very different. Why? Because the first retiree may be withdrawing money while the portfolio is down.
When you’re still working, a market decline can provide an opportunity to continue buying investments at lower prices through regular 401(k) contributions.
Retirement reverses that process. You may now be selling investments to pay for living expenses.
If you’re forced to sell during a significant downturn to fund withdrawals, those assets are no longer there to fully participate when markets recover.
This is known as sequence-of-returns risk. And it is one reason the beginning of retirement can be particularly important.
Retirement Spending Doesn’t Always Start Slowly
There is another challenge. Many people assume their spending will immediately decline once they retire.
Sometimes it does. But spending doesn’t necessarily decline immediately once you retire.
You finally have time to travel. You replace the vehicle you’ve been putting off. You renovate the kitchen. You help children or grandchildren. You buy the boat you’ve talked about for 20 years.
None of those decisions are necessarily mistakes. After all, enjoying retirement is the point.
But there are also expenses that may be harder to control. Healthcare is one of them.
According to EBRI’s 2026 Retirement Confidence Survey, two in five retirees said their healthcare expenses in retirement have been higher than expected. Yet fewer than half of workers and retirees said they have calculated how much they will need for healthcare expenses in retirement.
That makes planning for the early years a balancing act. You want to enjoy the freedom you’ve worked for while understanding what today’s spending decisions may mean over a retirement that could last another 25 or 30 years.
Your Last Paycheck Doesn’t Have To Trigger Social Security
Retirement also introduces one of the biggest financial decisions many Americans will make. When to claim Social Security.
It can be tempting to view retirement and Social Security as the same decision. You retire, so you start collecting your benefit.
But they don’t necessarily need to happen at the same time.
For some retirees, using other assets to fund the early years of retirement while delaying Social Security may result in a higher monthly benefit later. For others, claiming earlier may make sense based on their circumstances.
The important point is that leaving your job shouldn’t automatically make the decision for you. Social Security should be considered as part of the broader retirement income strategy.
The Tax Window Many Retirees Overlook
The first years of retirement can also create a potential tax-planning opportunity.
While working, your taxable income may have been near its highest level. Later in retirement, required minimum distributions, Social Security and other income sources may increase taxable income again.
But there can be a period in between when taxable income temporarily declines. That window may create opportunities to strategically withdraw money from tax-deferred accounts or consider Roth conversions.
The objective isn’t simply to pay the least amount of tax this year. It is to consider how today’s decisions may affect taxes throughout retirement.
Sometimes voluntarily recognizing income during a lower-income year can help reduce potential tax pressure later.
The Portfolio That Got You There May Not Be The Portfolio You Need
One of the easiest mistakes to make is reaching retirement and simply continuing with the same investment strategy.
But the job of your portfolio has changed.
During your working years, the primary objective may have been accumulation. Now the portfolio may need to provide income as well.
That doesn’t mean abandoning growth. A retirement lasting several decades may still require meaningful exposure to assets capable of outpacing inflation.
But it does mean thinking differently about liquidity, withdrawals and risk.
How much money will you need from the portfolio over the next year? What about the next three years? What happens if the market falls significantly during that period?
Having those conversations before a downturn is much easier than making decisions in the middle of one.
Don’t Put Retirement On Autopilot
Retirement can feel like the finish line. Financially, it may be closer to the beginning of a new phase.
The decisions made during the first several years can influence taxes, Social Security income, investment withdrawals and how much flexibility you maintain later in life.
That doesn’t mean retirees should spend their first five years worrying about every dollar. Quite the opposite.
Good planning is intended to give you a framework for enjoying retirement while understanding how spending decisions may affect.
But that requires recognizing how important the transition into retirement really is.
You can spend 30 or 40 years accumulating retirement savings. Once the paycheck stops, the rules change.
Reaching retirement is one financial milestone. Successfully transitioning into it is another.
