What's the best age to retire? How to decide what works for you

The best age for you to retire depends on factors from your savings to your health and more.

4 min read |

Quick takeaways

There is no single “best” retirement age—the right time depends on your finances, health, goals, and what retirement success looks like for you.Age‑based milestones matter—from catch‑up contributions at 50 to Medicare at 65 and Social Security options between 62 and 70, all of which shape when retiring is financially realistic.Your daily lifestyle vision should guide your timing—consider your health, desired routines, and how you want to spend your time.

What’s the universally accepted best age to retire? The answer might surprise you: There isn’t one. 

Your best retirement age depends on multiple factors including your goals, health, finances, work history, savings ability and habits, and spending needs. When you choose to take Social Security, how you maximize investment growth, and Medicare eligibility also matter. And, your best age to retire also depends on how you define retirement success.

Even if you choose an age at which you’d like to retire, unexpected health events or economic shifts can alter your plans. So how do you start to think about your best age to retire? These planning tips can help.

Major retirement financial milestones by age

Age-based financial rules and benefits can provide a useful framework for deciding when you might want to retire. As you age, you may be able to put more away in retirement savings, for example, or enroll in federal benefit programs like Medicare.

AgeOption that may influence retirement
50You can make catch-up contributions for employer-sponsored retirement plans like 401(k)s and IRAs.
55If you leave your job or retire, you may withdraw money, penalty free, from retirement plans.
59½Penalty-free withdrawals, regardless of work status, may be made from retirement plans. You may still owe income tax on distributions.
62This is the earliest age you may collect Social Security benefits, albeit at 70% of the full benefit. That decrease in benefit level is typically permanent.
64–65Enrollment for Medicare opens at age 64, with coverage beginning at age 65. Medigap supplemental coverage, which may help with some co-pays and deductibles, is also available.
66This is full retirement age (FRA) for anyone born 1943-1959, entitling them to 100% of Social Security benefits.
67This is full retirement age (FRA) for anyone born 1960 or later, entitling them to 100% of Social Security benefits.
70The age at which you can collect the maximum Social Security amount, up to 124%.
73You must start making withdrawals—called required minimum distributions (RMDs)—from certain retirement plans.
How finances shape your retirement choices

Three big categories in your financial picture will also help you shape the best age for you to retire.

Your retirement savings and income

How much you’ve saved for retirement is one of the biggest factors in your choice of an age to retire. To understand whether you have enough, start by reviewing your fixed and variable expenses to build a monthly budget. Then, list all your retirement savings sources like 401(k)s, IRAs, and other accounts to see the full picture. (This retirement budget worksheet (PDF) can help.) One consideration: If you haven’t saved enough or would like to build a bigger cushion, think about catch-up retirement account contributions after age 50, extending that retirement age, or even working part-time.

Your retirement savings and income

Social Security is, of course, one part of retirement income. As mentioned above, you can start benefits at age 62, but your benefits increase if you wait. It’s helpful to work through the scenarios as you estimate expenses, income, and your retirement age.

Your potential healthcare costs

If you retire or leave the workforce before age 65, you do have a few options for early retiree health care, but it’s essential to include those costs in any potential budgets for your retirement. Once you hit age 65, you’re eligible for Medicare.

How health and lifestyle impact your retirement age

Retirement depends not just on your goals, but also on how you feel physically and emotionally. If your health requires more time, energy, or money, it can influence when and how you choose to retire.

In addition, people in physically demanding jobs may find it harder to work later in life, as chronic pain, mobility limitations, or fatigue can make continuing full-time work unrealistic. Emotional health matters too—stress, burnout, or caregiving responsibilities can push some to retire earlier than planned. On the other hand, work can provide joy, purpose, and social connection, which may motivate you to stay employed longer. Understanding both your physical needs and your emotional well-being can help you decide what retirement age truly supports a healthy life.

How your goals shape your retirement age choice

As you think about retirement, it’s important to picture what everyday life will look like—not just the big trips or dream goals, but the rhythms and routines that shape your well-being. Consider how you want to spend your time, who you want to spend it with, and what brings you purpose or joy. Whether that means traveling, spending more time with family, diving into new hobbies, starting a small business, or working part‑time, your vision for daily life can guide your financial decisions and help you choose a retirement age that supports the lifestyle you truly want.
