The United States has no single legal retirement age for most workers. What it does have is a set of program rules that reward waiting and penalize claiming early, and those rules land on four familiar numbers. Here is what each one really means — and where each guess comes from.
Part of the confusion is that "retirement age" describes three different things at once: the age you can start collecting Social Security, the age you qualify for Medicare, and the age you can claim your full, unreduced benefit. They are not the same number, and they have never been the same number. Add in the fact that most people stop working before they claim, and the picture gets blurrier still.
Recent surveys have put the average self-reported retirement age in the low 60s, while the average age at which people start Social Security sits a few years later. In other words: the age people retire and the age people claim are usually two different decisions, made months or years apart.
The four ages people mean
Each guess below is a real rule, not a myth. The mistake is treating any one of them as the whole answer. Read them as a set: 62 is the earliest door, 65 is the health insurance door, 67 is the full-benefit door, and 70 is the maximum door.
62 — the first age you can claim Social Security
Age 62 is the earliest age most people can start retirement benefits, and it is the number many workers picture when they hear "retirement age." It is real, but it is also the most expensive option in the system: claiming at 62 permanently reduces your monthly benefit, and the size of that reduction depends on your full retirement age.
If your full retirement age is 67, claiming at 62 cuts your monthly benefit by about 30%. If it is 66, the cut is roughly 25%. That lower amount generally follows you for life, including into the survivor benefit your spouse may later receive. There is also the earnings test: if you claim before full retirement age and keep working above the annual limit, part of your benefit can be temporarily withheld.
- First eligible
- Age 62
- Benefit change
- Up to 30% lower
- Best fit
- Health or job loss forces early income
65 — the Medicare milestone, not the Social Security one
Age 65 is the traditional answer for a reason that has nothing to do with paychecks: it is when most Americans become eligible for Medicare. Your initial enrollment window is seven months wide — the three months before your birthday month, the birthday month itself, and the three months after. Miss it without other qualifying coverage and you may owe a late-enrollment penalty on Part B premiums for as long as you have Part B.
What 65 does not do is make you eligible for full Social Security. For anyone born in 1943 or later, full retirement age is 66 or older. So a worker claiming at 65 usually takes a permanent reduction of roughly 13% to 14% per year of early claiming, depending on birth year.
Plenty of people still retire at 65 for a practical reason: employer health coverage typically ends when the job does. If that is your trigger, plan the insurance transition before you plan the claiming date.

- 7 months
- Social Security
- Usually reduced
67 — full retirement age for anyone born in 1960 or later
If there is a "correct" answer in the Social Security rulebook, this is it. Full retirement age — the age at which you receive 100% of the benefit calculated from your earnings record — is 67 for everyone born in 1960 or later. It slides from 66 to 67 for people born between 1955 and 1959, in two-month steps per birth year.
Claiming at 67 means no early-claiming reduction and no need to worry about the earnings test. It is also the point from which delayed retirement credits begin: for each full year you wait beyond full retirement age, your benefit grows by about 8%, up to age 70.
For many households, 67 is the neutral benchmark — the number to compare every other plan against. Retiring from work at 67 and claiming at 67 are, of course, two separate choices, and doing both at once is neither required nor discouraged.
- Full benefit at
- Age 67
- Born in
- 1960 or later
- Credits after
- About 8% a year
70 — the largest monthly check the system allows
Delayed retirement credits stop at 70, which makes it the last useful date in the claiming calendar. Someone with a full retirement age of 67 who waits until 70 receives about 124% of their full benefit, adjusted for cost-of-living increases along the way. Nothing improves after 70, so waiting longer only costs you money.
Age 70 also gets attention because it works like longevity insurance: the benefit is inflation-adjusted and lasts as long as you live. That is why many planners point the higher earner in a married couple toward 70 while the lower earner may claim earlier — it can protect the survivor benefit.
The catch is that delaying requires other money to live on between your last paycheck and your first benefit. Without savings, a pension, or continued work income, waiting is not a strategy — it is a wish.

- Age 70
- Benefit level
- About 124% of full

How the four ages compare
The table below assumes a full retirement age of 67, which applies to anyone born in 1960 or later. Percentages describe the Social Security benefit only; they say nothing about Medicare premiums or taxes.
| Claiming age | Benefit vs. full | What it is really about | Main trade-off |
|---|---|---|---|
| 62 | About 70% | Earliest cash flow | Permanent reduction plus earnings-test withholding if you keep working |
| 65 | About 86–87% | Medicare eligibility | Insurance begins, but the benefit is still reduced for life |
| 67 | 100% | Full retirement age | No reduction, no earnings test, no delayed credits |
| 70 | About 124% | Maximum monthly amount | Largest check, but you must fund the waiting years yourself |
So which one is the real retirement age?
All four are real; none of them is complete. The honest answer is that the real retirement age in America is the age your income, savings, health coverage, and family situation can actually support — then adjusted for the rules above so you are not leaving money on the table by accident.
- If you need income now, 62 is available, but treat the reduction as a permanent cost rather than a rounding error.
- If health coverage is the deciding factor, 65 is your planning anchor and Social Security timing is a separate decision.
- If you want the benchmark, 67 is where the full formula applies for people born in 1960 or later.
- If longevity runs in your family, 70 maximizes the inflation-adjusted income that cannot be outlived.
Two other dates belong in the same conversation. Required minimum distributions from most traditional retirement accounts generally begin at 73 for people born between 1951 and 1959, and at 75 for those born in 1960 or later. And Medicare enrollment at 65 is separate from work: you can be working full time and still need to sign up on time.

Frequently asked questions
No. The United States does not set a single legal retirement age for most workers. Federal programs use their own milestones instead: reduced Social Security claims from 62, full benefits at a full retirement age of 66 or 67 depending on birth year, maximum benefits at 70, and Medicare eligibility generally at 65.
Not usually. Age 65 is primarily a Medicare milestone. Full retirement age is 66 or 67 for anyone born in 1943 or later, and 67 for anyone born in 1960 or later, so claiming at 65 generally means a permanently reduced monthly benefit.
Yes. If you are under full retirement age and earn above the annual earnings limit, part of your benefit may be temporarily withheld. Withheld money is not forfeited — your benefit is recalculated once you reach full retirement age.
Age 70 produces the largest monthly benefit because delayed retirement credits stop there, but it is not automatically best for everyone. The right age depends on health, cash needs, work plans, marital status, and how your benefits are taxed. Break-even points matter: for many people, waiting to 70 pays off only if they live well into their early-to-mid eighties.
Indirectly. Required minimum distributions are tied to birth year, not to your retirement date: generally age 73 for people born from 1951 through 1959, and age 75 for those born in 1960 or later. Retiring earlier does not delay them, and retiring later does not push them back.
