Introduction

This Social Security Retirement Age Calculator shows you two things: your Full Retirement Age (FRA) and how much your monthly check changes based on when you claim.

Your FRA depends on the year you were born. For people born in 1960 or later, it is 67. For people born from 1943 to 1959, it falls between 66 and 66 years and 10 months. At your FRA, you get 100% of your benefit.

You can start Social Security as early as age 62, but your check will be smaller for life. If you wait past your FRA, your check grows by 2/3 of 1% each month, which is 8% per year. That growth stops at age 70.

Pick your birth year and month, choose the age you plan to claim, and add your FRA benefit amount from your Social Security Statement at ssa.gov. The calculator returns your adjusted monthly benefit, the math behind it, a table of every claiming age from 62 to 70, and a chart so you can compare your choices side by side.

How to use our Social Security Retirement Age Calculator

Enter your birth date, the age you plan to claim Social Security, and your estimated benefit at Full Retirement Age. The calculator shows your Full Retirement Age, how much your benefit goes up or down, and your adjusted monthly payment.

What year were you born? Pick your birth year from the list. This sets your Full Retirement Age, which is 66 for people born in 1954 or earlier and 67 for people born in 1960 or later.

What month were you born? Choose your birth month. This tells you the exact month and year you reach Full Retirement Age.

At what age do you plan to claim benefits? Pick the years and months. You can start as early as age 62. Waiting past your Full Retirement Age adds credits, but they stop at age 70.

Your estimated monthly benefit at Full Retirement Age. Type the dollar amount from your Social Security Statement at ssa.gov. You can leave this blank if you only want to see percentages.

Fine-tune your claiming age. Drag the slider to change your claiming age one month at a time. Use the arrow keys to move by a month, or Page Up and Page Down to move by a year.

Social Security Retirement Age: What It Means

Social Security pays a monthly check when you retire. The size of that check depends a lot on when you start it. You can start as early as age 62, or wait as late as age 70. The longer you wait, the bigger each monthly check gets, and that change lasts for life.

Full Retirement Age (FRA)

Your Full Retirement Age is the age when you get 100% of the benefit you earned. It is set by the year you were born. People born in 1960 or later have an FRA of 67. People born in 1954 or earlier have an FRA of 66. Birth years in between land somewhere between those two ages.

Claiming Early Cuts Your Check

If you start before your FRA, Social Security lowers your monthly payment. The cut is based on how many months early you start:

  • The first 36 early months cut your benefit by 5/9 of 1% each month (about 0.556% per month).
  • Every month beyond those 36 cuts it by 5/12 of 1% each month (about 0.417% per month).

For someone with an FRA of 67, starting at 62 means a 30% cut that never goes away.

Waiting Past FRA Grows Your Check

If you wait past your FRA, you earn delayed retirement credits. Each month you wait adds 2/3 of 1%, which comes to 8% for a full year. These credits stop at age 70, so there is no reason to wait longer than that. Someone with an FRA of 67 who waits until 70 gets 124% of their full benefit.

How to Pick Your Age

There is no single right answer. Starting early gives you money sooner but smaller checks. Waiting gives you fewer years of checks but larger ones. Think about your health, your job, your savings, and whether a spouse will one day claim a survivor benefit based on your record. If you live a long life, waiting usually pays more in total. If you need income now or have health problems, claiming early can make sense.

Other Things to Know

  • Working while claiming early: If you start before FRA and keep working, the earnings test may hold back part of your check. That money is added back later once you reach FRA.
  • Medicare is separate: Medicare starts at 65 no matter what your FRA is.
  • Your real amount: Your benefit is based on your 35 highest earning years. Check your Social Security Statement at ssa.gov for your own numbers.
  • Cost-of-living raises: Benefits get yearly raises for inflation, whether you have started them or not.

Frequently asked questions

How many years do you have to work to get Social Security retirement benefits?

You need 40 work credits, which is about 10 years of work. You can earn up to 4 credits a year, and you get a credit for a set amount of covered wages.

But 10 years only makes you eligible. Your payment is based on your 35 highest earning years. If you worked fewer than 35 years, Social Security fills the empty years with zeros, which pulls your check down.

Is the full retirement age going up to 68 or 70?

No. Under current law, the full retirement age stops at 67 for everyone born in 1960 or later. It does not keep rising.

Congress has discussed raising it, but no law has passed. Age 62 is still the earliest you can claim, and age 70 is still the last age that adds delayed credits.

How much can you earn while collecting Social Security before your check is cut?

If you claim before your full retirement age and keep working, the earnings test applies. Social Security holds back $1 for every $2 you earn above the yearly limit (about $23,400 in 2025; the limit rises each year).

In the year you reach FRA, the limit is much higher and the hold-back is only $1 for every $3 above it. Once you reach FRA, the test goes away and you can earn any amount.

The money is not lost. After FRA, your check is recalculated and raised to give it back over time.

Are Social Security retirement benefits taxed?

Sometimes. It depends on your combined income: your other income plus half of your Social Security.

  • Single: up to 50% of your benefit can be taxed above $25,000, and up to 85% above $34,000.
  • Married filing jointly: the lines are $32,000 and $44,000.

These limits are not adjusted for inflation, so more retirees pay tax over time. Some states also tax benefits, but most do not.

What is the highest Social Security benefit you can get?

In 2025, the most a person could get at full retirement age was about $4,018 a month. Claiming at 62 capped out near $2,831, and waiting until 70 could reach about $5,108 a month. These caps rise a little each year.

To hit the top amount you must earn at or above the Social Security wage cap for 35 years, which very few workers do.

At what age does waiting to claim Social Security pay off?

The break-even point is usually somewhere in your late 70s to early 80s. Before that, the person who claimed early has collected more total dollars. After that, the person who waited pulls ahead and stays ahead for life.

So if you expect a long life, waiting usually wins. If you have health problems or need the income now, claiming early can make more sense.

Can I change my mind after I start Social Security?

Yes, in two ways.

  • Withdraw your claim: within 12 months of starting, you can cancel it by filing Form SSA-521. You must pay back every dollar you received. You can only do this once in your life.
  • Suspend your benefit: once you reach full retirement age, you can pause payments. Each month paused earns delayed credits until age 70, which raises your future check.

Does working after age 62 increase my Social Security benefit?

It can. Your benefit is figured from your 35 highest earning years, adjusted for wage growth. If a new year of pay beats one of those 35 years, it replaces the low year and your benefit goes up.

Social Security checks this every year automatically, even after you start collecting. If your new earnings are low compared to your past years, nothing changes.

Do cost-of-living raises still apply if I claim Social Security early?

Yes. The yearly cost-of-living adjustment (COLA) applies to everyone getting benefits, no matter when they claimed.

You even earn COLAs starting the year you turn 62, before you claim. Claiming early lowers the base amount, so the same percentage raise gives you fewer dollars, but you never miss the raises.

Why does my birth month matter for Social Security?

Because your full retirement age is counted in months, not just years. A person born in January reaches FRA in a different month than someone born in November of the same year, so their early or late months differ.

Two odd rules to know: Social Security treats you as reaching an age the day before your birthday, and if you were born on January 1, your FRA is set using the previous birth year.

How does my claiming age affect my spouse's survivor benefit?

A lot. When one spouse dies, the survivor can step up to the higher of the two benefits. So if the higher earner claims early, that smaller amount can follow the survivor for life.

If the higher earner waits past full retirement age, the delayed credits carry over to the survivor benefit too. That is why the higher earner in a couple often waits longer to claim.

Can I get Social Security at 62 and Medicare at the same time?

No. Medicare starts at 65 for almost everyone, no matter when you claim Social Security or what your full retirement age is.

If you claim Social Security before 65, you will need other health coverage until 65. If you are already getting benefits at 65, you are usually enrolled in Medicare Parts A and B automatically, and the Part B premium comes out of your monthly check.
