The 'One More Year' Retirement Delay Isn’t Paying Off Like It Used To

You've probably thought it before — one more year couldn't hurt. Another year of income, more savings, and higher Social Security benefits may feel like a safer path to set yourself up for retirement.

But that extra year doesn't always deliver what it promises. For many workers, the financial gain is smaller than expected, while the trade-offs, both financial and personal, are often overlooked.

Here's where the "one more year" idea starts to fall apart.

The appeal of working one more year

Delaying retirement can make a difference, especially for underfunded workers. NBER research shows that delaying retirement from 66 to 67 can increase annual retirement income by about 7.75%, with 83% of that gain coming from higher Social Security benefits.

For smaller portfolios, that boost adds savings while reducing early drawdowns. Psychologically, work also provides structure and social connection, which can make the transition into retirement feel less uncertain.

The financial math has limits

However, if you're in your 60s, these new savings don't have much time to compound. Adding another $20,000 or $30,000 may not significantly change your long-term outcome. At this stage, your portfolio size and withdrawal strategy matter more than incremental contributions.

In many cases, reducing future tax exposure or withdrawal risk has a bigger impact than one more year of savings. The benefit shrinks the closer you get to retirement.

It's difficult to time Social Security perfectly

Delaying Social Security increases your benefit by about 8% per year past full retirement age, but only until age 70. After that, there's no additional gain.

In practice, timing rarely works out perfectly. Health changes, job transitions, or market conditions often force earlier claims, which can reduce the expected benefit of waiting. Planning assumptions made years earlier often don't match real-life decisions at retirement.

Taxes can quietly reduce the benefit

That final working year often comes with peak earnings, which can push you into a higher tax bracket. For example, income above $103,350 for single filers or $206,700 for married couples is taxed at 24% or higher, meaning more of that extra salary is lost to taxes.

Higher income can also trigger IRMAA surcharges once MAGI crosses $109,000 (single) or $218,000 (married), increasing Medicare premiums later.

Health care costs don't change much

Fidelity estimates a 65-year-old may need about $172,500 in out-of-pocket healthcare costs during retirement. That number doesn't shift meaningfully if you retire at 63, 64, or 65. It reflects long-term medical spending rather than the exact retirement age.

Working longer doesn't materially reduce this expense. It may delay when you start paying it, but Medicare premiums, prescriptions, and ongoing care costs still accumulate over time.

The emotional side most retirees overlook

A 2025 study in Frontiers in Public Health found that delaying retirement can improve well-being, but the benefits are strongest for higher-income workers who choose to keep working, not those who feel pressured to stay. For others, results vary based on job stability and income.

When "one more year" is driven by uncertainty, it often reflects incomplete retirement planning, leading to unnecessary delays and ongoing financial anxiety.

Most workers don't retire when they plan to

Only three in four retirees feel confident about having enough money to live comfortably, according to the 2026 EBRI/Greenwald Retirement Confidence Survey. That uncertainty often drives the "one more year" decision.

But if there's a real chance that health issues or layoffs force you to retire earlier than expected, working an extra year becomes a fragile plan. Building around what you have today is often the more resilient approach.

Why early retirement years matter most

The first years of retirement are typically your healthiest and most active, and you can't reclaim them later. They're also the window before Social Security and required minimum distributions (RMDs) begin, when taxable income is often at its lowest.

With income low and no mandatory distributions yet, many retirees can execute Roth conversions at 10% or 12%. That moves assets into tax-free growth and meaningfully reduces future RMD pressure and lifetime tax exposure.

A better question to ask

Instead of asking, "Should I work one more year?" ask yourself, "What does my retirement actually cost, and can I fund it?" 

A retiree with $72,000 in expected annual spending, $2,400 in monthly Social Security, and a 4% withdrawal rate of $32,000 is in a clearer position than someone with $800,000 saved but no plan for how it translates to income.

When one more year does make sense

There are situations where delaying retirement helps. If you have a significant savings gap, need to boost Social Security, or want to reduce sequence-of-returns risk, an extra year can add stability.

But it should be a targeted decision tied to a specific goal, not a default move based on uncertainty. In many cases, a clear retirement income plan will show whether that extra year actually changes your long-term outcome.

Bottom line

Working one more year can improve your finances, but the benefit isn't as large or as universal as it once seemed. For many retirees, the marginal gain is small compared to the time they give up.

The better approach is to focus on clarity. When you understand your true retirement costs and tax exposure, you can make decisions that support your financial fitness, rather than relying on extra working years.
