Use the USA Social Security Retirement Calculator below to compare your estimated monthly and annual benefits at different claiming ages from 62 through 70.
How to Use the Social Security Retirement Calculator
You only need a few details to get started.
- Select your year of birth. This helps determine your Full Retirement Age (FRA).
- Enter your estimated monthly benefit at Full Retirement Age. For a better estimate, use the amount shown in your Social Security record.
- Choose the age you plan to claim Social Security. You can compare claiming ages from 62 through 70.
- Click “Calculate My Social Security Benefit.” The calculator will show your estimated monthly and annual retirement benefit.
You will also see how claiming earlier or later could change your estimated payment.
For a personalized benefit estimate based on your actual earnings record, you can check your my Social Security account. The SSA specifically recommends its personal account for viewing future retirement estimates at different claiming ages.
What Your Results Mean
Your calculator results provide several useful estimates.
Estimated Monthly Benefit shows approximately how much Social Security retirement income you could receive each month at your selected claiming age.
Estimated Annual Benefit converts the monthly estimate into an approximate yearly amount.
Full Retirement Age shows the age at which you become eligible for your unreduced retirement benefit based on your birth year.
Claiming Adjustment shows how starting benefits before or after Full Retirement Age changes the estimate.
The comparison table lets you see estimated benefits at different ages, making it easier to compare claiming Social Security at 62, Full Retirement Age, 70, or another age in between.
How Are Social Security Retirement Benefits Calculated?
Social Security retirement benefits are based primarily on your lifetime covered earnings and the age at which you start receiving benefits.
The Social Security Administration uses your highest 35 years of indexed earnings when calculating your retirement benefit. If you have fewer than 35 years of earnings, years without earnings can be counted as zeros, which may reduce your benefit.
The official calculation is more complex than simply multiplying your salary by a percentage. Earnings are indexed, an Average Indexed Monthly Earnings (AIME) amount is calculated, and that figure is used to determine your base retirement benefit.
Our calculator is designed differently: it starts with the Full Retirement Age benefit estimate you enter and helps you understand how your claiming age may change that amount.
What Is a Full Retirement Age?
Full Retirement Age (FRA) is the age when you become eligible for your full, unreduced Social Security retirement benefit. It depends on your year of birth.
| Year of Birth | Full Retirement Age |
| 1937 or earlier | 65 |
| 1938 | 65 and 2 months |
| 1939 | 65 and 4 months |
| 1940 | 65 and 6 months |
| 1941 | 65 and 8 months |
| 1942 | 65 and 10 months |
| 1943–1954 | 66 |
| 1955 | 66 and 2 months |
| 1956 | 66 and 4 months |
| 1957 | 66 and 6 months |
| 1958 | 66 and 8 months |
| 1959 | 66 and 10 months |
| 1960 or later | 67 |
The gradual increase in Full Retirement Age resulted from changes enacted in 1983. For people born in 1960 or later, FRA is 67.
How Does Claiming Age Affect Social Security Benefits?
You can generally start Social Security retirement benefits between age 62 and age 70. Starting earlier usually means receiving a smaller monthly benefit, while delaying benefits beyond Full Retirement Age can increase the monthly payment up to age 70.
Claiming Social Security at Age 62
Age 62 is generally the earliest age at which you can start Social Security retirement benefits.
However, claiming before your Full Retirement Age reduces your monthly benefit. The reduction can be significant when your FRA is 67 and you begin receiving benefits at 62.
This is why comparing age 62 with later claiming ages can be useful before making a retirement decision.
Claiming at Full Retirement Age
At your Full Retirement Age, you are eligible for 100% of your calculated Full Retirement Age retirement benefit.
Your FRA may fall between ages 65 and 67 depending on your birth year. For anyone born in 1960 or later, it is age 67.
Delaying Social Security Until Age 70
Your monthly retirement benefit can increase when you delay claiming beyond Full Retirement Age.
For example, someone born in 1960 or later has an FRA of 67. According to the SSA, delaying from 67 until 70 results in a benefit equal to 124% of the Full Retirement Age monthly amount. Benefits stop increasing because of delayed retirement once you reach age 70.
Social Security at 62 vs. 67 vs. 70
For someone with a Full Retirement Age of 67, the basic comparison looks like this:
| Claiming Age | General Effect |
| 62 | Start sooner, but receive a permanently reduced monthly benefit |
| 67 | Receive 100% of the Full Retirement Age benefit |
| 70 | Receive delayed retirement credits and a higher monthly benefit |
There is no single claiming age that is automatically best for everyone.
Your health, expected longevity, employment, other retirement income, spouse or family benefits, taxes and immediate income needs can all affect the decision.
The calculator is therefore intended to compare estimated benefit amounts, not tell you which age you should choose.
Does Working Longer Increase Your Social Security Benefit?
It can.
Social Security generally uses your highest 35 years of earnings. If you continue working and a new higher-earning year replaces a lower-earning year in your record, your eventual benefit may increase.
Conversely, stopping work with fewer than 35 years of earnings can reduce your benefit because years without earnings may be included as zeros.
This is an important limitation when using a calculator based on your existing Full Retirement Age estimate: if your future earnings change substantially, your eventual SSA benefit may also change.
Is This an Official Social Security Calculator?
No. This USA Social Security Retirement Calculator is an independent planning tool and is not affiliated with, endorsed by, or operated by the Social Security Administration or the U.S. government.
The calculator provides estimates for educational and retirement-planning purposes.
Your actual Social Security benefit depends on your official earnings record, eligibility and applicable Social Security rules.
For an official personalized estimate, use your Social Security account. You can also review the SSA’s retirement planning information.
What This Calculator Does Not Calculate
This calculator focuses specifically on Social Security retirement benefits. It does not calculate your entire U.S. retirement income.
It does not currently calculate:
- 401(k) withdrawals or investment growth
- Traditional or Roth IRA income
- Private employer defined-benefit pensions
- Federal, state or local government pensions
- Military retirement pay
- SSI or disability benefits
- Survivor benefits
- Spousal benefits
- Medicare premiums or deductions
- Federal or state taxes on retirement income
Keeping this distinction clear is important because Social Security retirement benefits are only one potential source of retirement income.
Frequently Asked Questions
What is a Social Security retirement calculator?
A Social Security retirement calculator estimates how your retirement benefit may change depending on factors such as your Full Retirement Age benefit and the age at which you start claiming. Our calculator lets you compare estimated monthly and annual benefits across different claiming ages.
What is the earliest age I can claim Social Security retirement benefits?
For most workers, Social Security retirement benefits can begin as early as age 62. Starting before Full Retirement Age generally results in a reduced monthly payment.
What is my Full Retirement Age?
Your Full Retirement Age depends on your birth year. It ranges from 65 for older generations to 67 for people born in 1960 or later.
Will my Social Security benefit increase if I wait until 70?
If you delay retirement benefits beyond your Full Retirement Age, delayed retirement credits can increase your monthly benefit. The increase stops at age 70, so delaying the start of benefits beyond 70 does not generate additional delayed retirement credits.
Does Social Security use my last 5 years of salary?
No. Social Security does not simply calculate retirement benefits from your last few working years. The SSA generally uses your highest 35 years of indexed earnings when calculating retirement benefits.
What happens if I have fewer than 35 years of work?
Years without earnings can be included as zeros when Social Security calculates your highest 35-year earnings record. Those zero years can lower your retirement benefit.
Is this calculator’s estimate guaranteed?
No. The result is an estimate, not a guarantee of future Social Security payments. Your official benefit is determined by the Social Security Administration using your complete earnings and eligibility record.
Is Social Security the same as a private pension?
No. Social Security is a federal social insurance program. A private pension is typically an employer-sponsored retirement plan. This calculator estimates Social Security retirement benefits and does not calculate private pension payments.
