What full retirement age means and how it affects your benefits

Full retirement age is the age at which Social Security calculates your benefit as 100% of what you earned. If you were born in 1943 or later, your full retirement age is not 65 — it has been gradually pushed back to 66, 67, or somewhere in between, depending on your birth year. This change was written into law in 1983 and has been rolling out ever since.

You can still claim Social Security as early as 62, but your monthly payment will be permanently smaller — roughly 30% less if you claim at 62 instead of waiting until full retirement age. If you wait past full retirement age, your payment grows by about 8% per year until age 70. The age you choose to claim is one of the biggest financial decisions you will make as a retiree, because it affects every check you receive for the rest of your life.

The reason Congress changed the law was simple: people were living longer, and the program's finances were strained. By pushing full retirement age forward, the government reduced what it had to pay out each year without cutting benefits for people already retired.

Key Takeaways

  • Full retirement age has been gradually increasing since 1983 and now ranges from 66 to 67 depending on your birth year.
  • Claiming at 62 reduces your monthly benefit by roughly 30%, and that reduction is permanent for your entire life.
  • Waiting until 70 increases your monthly benefit by about 8% per year compared to full retirement age.
  • You can find your specific full retirement age on your Social Security statement or by using the Social Security Administration's online calculator.
  • The age change affects when you become may be able to access for Medicare and when you must start taking required withdrawals from retirement accounts.

Birth year and full retirement age: the schedule

The Social Security Administration increased full retirement age in two-month increments over a 22-year period. If you were born between 1943 and 1954, your full retirement age is 66. If you were born between 1955 and 1960, it falls somewhere between 66 and 67 — the exact month depends on your birth month. If you were born in 1960 or later, your full retirement age is 67.

The law does not go any higher than 67. Even if you are very young now, 67 is the maximum full retirement age the current law sets. Congress would have to pass new legislation to push it higher.

You can look up your exact full retirement age on your Social Security statement, which you can view online at ssa.gov if you have created an account. The statement also shows an estimate of what your benefit would be at different ages — 62, full retirement age, and 70. This estimate is based on your actual earnings record, so it is more accurate than any general number you will read.

Why claiming age matters more than you might think

The difference between claiming at 62 and waiting until 70 is not just a few hundred dollars a month — it compounds over decades. If your full retirement age benefit would be $2,000 per month, claiming at 62 might give you $1,400, while waiting until 70 might give you $2,480. Over a 20-year retirement, that is a difference of nearly $260,000 in total payments.

The trade-off is that you receive nothing while you wait. If you claim at 62, you start collecting immediately. If you wait until 70, you are betting you will live long enough to break even. For most people, the break-even point is somewhere in the mid-80s. If you live past that, waiting pays off. If you do not, claiming early was the better choice.

Health, family history, and how much you have saved outside Social Security all matter. Someone in excellent health with substantial retirement savings might benefit from waiting. Someone with serious health problems or limited savings might benefit from claiming early. There is no single right answer — it depends on your situation.

How the age change connects to Medicare may be able to access

Medicare may be able to access is separate from Social Security, but the two are often confused. You become may be able to access for Medicare at 65, regardless of your Social Security full retirement age. You can claim Social Security at 62 and still wait until 65 to enroll in Medicare, or you can claim Social Security at 70 and enroll in Medicare at 65.

If you do not enroll in Medicare when you first become may be able to access at 65, you may face a permanent penalty on your premiums — unless you have employer coverage or meet other exceptions. This penalty is separate from your Social Security decision and applies whether you claim Social Security early or late.

The key point: do not assume that your full retirement age for Social Security is the same as your Medicare enrollment age. They are two different programs with two different ages.

Full retirement age and required minimum withdrawals from retirement accounts

The age at which you must start taking money out of traditional IRAs and 401(k)s is called the required minimum distribution age, or RMD age. As of 2023, that age is 73 for most people — it was raised from 72 by the SECURE 2.0 Act. This age is also separate from your Social Security full retirement age.

You can claim Social Security at 62 and delay your RMDs until 73. Or you can wait until 70 to claim Social Security and still have to start RMDs at 73. The three ages — early claiming (62), full retirement age (66 or 67), and RMD age (73) — are independent of each other. Understanding which age applies to which decision prevents costly mistakes.

What changed in 1983 and why it matters now

Before 1983, full retirement age was 65 for everyone. The 1983 amendments to the Social Security Act gradually moved it forward because the program's trust fund was running low. Fewer workers were paying in relative to the number of retirees collecting, and people were living longer than they had in the 1930s when the program started.

By raising the full retirement age, Congress reduced the program's long-term costs without cutting benefits for people already retired or close to retirement. It was a compromise: younger workers would work longer before receiving their full benefit, but the program would remain solvent.

That compromise is now 40 years old, and the program faces similar pressures again. The trust fund is projected to be depleted sometime in the 2030s if Congress does not act. Whether full retirement age will be raised again depends on what Congress decides, but no change has been made yet.

How to find your full retirement age and plan accordingly

The fastest way to find your full retirement age is to create an account at ssa.gov and view your Social Security statement. The statement shows your full retirement age, your estimated benefit at different claiming ages, and your complete earnings record. You can also call Social Security at 1-800-772-1213 to ask, though wait times are often long.

Once you know your full retirement age, you can think through the trade-offs. If you are still working, claiming before full retirement age may reduce your benefit if you earn above a certain threshold — Social Security will withhold $1 for every $2 you earn above the limit. If you are retired and have no other income, that limit does not apply. These details matter for your specific situation.

Many people find it helpful to run the numbers at different claiming ages using the Social Security Administration's online calculator or by asking a financial advisor to model it out. The goal is not to find the "right" age — it is to understand what you are trading off and make a choice you can live with.

Frequently Asked Questions

Can I change my mind after I claim Social Security?

You can withdraw your claim within 12 months of claiming and repay what you received, which resets your account as if you never claimed. After 12 months, you cannot undo it. You can suspend your benefits at full retirement age and let them grow until 70, but you must have already claimed to do this. The rules are strict, so ask Social Security directly before making any changes.

Does my full retirement age affect when I can work without losing benefits?

Yes. If you claim before full retirement age and earn income, Social Security withholds $1 for every $2 you earn above a yearly limit (the limit changes each year). Once you reach full retirement age, there is no earnings limit. This is one reason some people wait to claim — it removes the earnings penalty.

What if I was born on January 1st — which year's rules apply to me?

Social Security treats people born on January 1st as if they were born on December 31st of the previous year. So if you were born on January 1, 1955, Social Security considers you born in 1954. Check your Social Security statement to confirm which cohort you fall into.

Is my spouse's full retirement age different from mine?

Yes. Each person has their own full retirement age based on their own birth year. If you and your spouse were born in different years, you may have different full retirement ages. Spousal benefits and survivor benefits have their own rules and ages, which are separate from your own full retirement age.

Will Congress raise full retirement age again?

That is a policy decision Congress has not yet made. The Social Security trust fund faces long-term financing challenges, and raising full retirement age is one option policymakers have discussed. No change has been enacted, and any change would likely be phased in gradually over many years, just as the 1983 change was.
