At last check, Americans think they need $1.26 million to live comfortably in retirement. If you are among the millions who are getting closer to retirement but don’t think you have enough money saved, don’t despair. There are ways to shore up extra cash; one powerful way is to work longer.

That doesn’t mean you have to keep working for an extra five years or decade. But even six months or a year can have a meaningful impact on your retirement nest egg.

“Retirement is a twenty-year horizon, and essentially what you are doing is prioritizing your future by working six months longer,” says Nick Nefouse, global head of retirement solutions and head of LifePath at BlackRock.

“Six months longer means you are saving for six more months, deferring Social Security for six months and deferring drawing capital for six months.”

The same triple benefit applies to nine months or twelve months and beyond. Time allows you to amass more money for when you do retire.

When it comes to spending money in retirement, income typically comes from several sources, including Social Security benefits, pensions, a 401(k), IRA or other tax-advantaged retirement accounts. You can also tap investment accounts and any income from part-time jobs like consulting gigs. The timing of your retirement will impact all of those buckets differently.

Take Social Security. While you can begin collecting benefits at 62, the longer you wait, the bigger your monthly check will be.

If you begin collecting at 62 (the earliest age possible), your benefit is reduced by 30%.
If you collect at your Full Retirement Age or FRA (typically around 67, depending on when you were born), you will receive your full benefits.
If you collect at 70, you receive a 30.7% increase in your benefits compared to FRA.

If you are on the cusp of hitting your FRA (meaning you are around age 66 in most cases), delaying for six months, nine months or a year will result in a 30% boost in your benefits.

If you are of FRA and delay retiring for even six months, it can mean bigger payments when you begin collecting. That’s because your Social Security benefits are calculated based on your 35 highest-earnings years, adjusted for inflation. If you are at your peak earnings and hold off, that’s more months calculated into your earnings.

“Any timeframe — if it's six months, nine months, a year — you continue to work, not only is it additional time to save for retirement, but it could help put off taking Social Security,” says Sharon Carson, executive director of J.P. Morgan Asset Management.

“If you don’t have 35 years of earnings or you have some early years you weren’t paid very well, then [delaying] will help. A lot of people make more at the end of their career than in the beginning.”

How working longer can impact your retirement savings

To say the stock markets have been volatile in 2025 is an understatement. From days of 1,000-point-plus declines to days of 3,000-point-plus increases, the stock markets and retirement savings accounts have been all over the place in recent months.

If you are staring despondently at losses in your account, working even six months longer can give you the time to recoup your losses, and then some. But if you retire when your portfolio is experiencing negative returns, it can have a big impact on the amount of money you can withdraw annually and how long it will last.

“The longer you are invested, the more the volatility will be smoothed out,” says Nefouse.

How working longer can impact your happiness

Rewind a few decades, and retirement was a hard stop. You selected a date to retire, and after that, you began collecting Social Security, a pension and withdrawals from your retirement savings account.

These days, people tend to take a phased approach to retirement. They may slow down and stop working sixty hours a week, but that doesn’t mean the paycheck ends entirely.

You could stop working overtime, reduce your hours, move to part-time work, consult or freelance. While you may not be working as much, you’re still bringing in income, which prevents you from drawing down on your savings.

“If you have the ability, working longer is both financially good and mentally good,” says Nefouse.

How much can you save working six months, nine months and a year longer

Still not convinced? Here’s how much you save by working longer assuming:

You are 67, have $500,000 in your 401(K) returning 5% annually, earn $150,000 per year, contribute 10% of your income to your 401(k) and if you retired today would receive $2,400 in monthly Social Security benefits.

Waiting six more months
401(k) would increase by $22,613
Social Security would increase by $576 per year

Waiting nine more months
401(k) would increase by $34,003
Social Security would increase by $1,728 per year

Waiting 12 more months
401(k) would increase by $45,450
Social Security would increase by $2,304

Is waiting right for you?

Whether you work a few months or retire as planned depends on your finances and mental and physical health. Carson says to ask yourself a series of questions to see if you are ready.

Do you have a plan that makes you feel financially secure? If yes, then are you ready psychologically? Do you have a plan for what you’ll do in retirement? If you do, then retiring is a no-brainer.

But if you answer no, ask yourself what you can do to adjust your lifestyle to make you feel more secure.

If working a few more months or a year is the answer, go for it; you’re nest egg will thank you.
