What Your Social Security Benefit Will Be
Your Social Security benefit is based on your earnings record — specifically, the 35 years in which you earned the most money. The Social Security Administration (SSA) calculates this by taking your highest 35 years of wages, adjusting them for inflation, and then running them through a formula that produces your Primary Insurance Amount (PIA). This PIA is what you would receive per month if you start benefits at your full retirement age.
The exact dollar amount depends on three things: how much you earned over your working life, when you were born (which determines your full retirement age), and when you decide to start taking benefits. You cannot calculate this by hand with any accuracy — the formula is complex and the inflation adjustments change yearly. But you can see the SSA's estimate of your benefit, and you can understand how the timing decision affects what you actually receive.
Key Takeaways
- The SSA bases your benefit on your 35 highest-earning years, adjusted for inflation, then applies a formula that produces your Primary Insurance Amount.
- Your full retirement age ranges from 66 to 67 depending on your birth year, and this is the age at which you receive your full calculated benefit.
- You can claim as early as 62, but your monthly payment will be permanently reduced — typically 25 to 30 percent lower than your full retirement age amount.
- You can delay claiming past your full retirement age until 70 and receive an 8 percent annual increase for each year you wait, up to a maximum 24 to 32 percent boost.
- The SSA provides a free estimate of your benefit on your my Social Security account, which you can create at ssa.gov.
How the SSA Calculates Your Earnings Record
The SSA keeps a record of every year you worked and paid Social Security taxes. When you turn 60, the agency begins tracking your record for benefit calculation purposes. The formula uses your 35 highest-earning years — if you worked fewer than 35 years, the missing years count as zero, which lowers your average.
Before the SSA applies its benefit formula, it adjusts your historical earnings for inflation using a method called wage indexing. This means a dollar you earned in 1990 is not compared directly to a dollar you earned in 2020. Instead, the SSA scales your older earnings upward so they reflect the wage levels of the year you turn 60. This adjustment is why your benefit reflects your lifetime earning power, not just your recent paychecks.
You can see your own earnings record by logging into your my Social Security account at ssa.gov. The record shows what the SSA has on file for each year you worked. If you spot an error — a missing year, a year with too-low earnings, or a year that should not be there — you can contact the SSA to correct it. Errors are not uncommon, especially if you changed jobs, were self-employed, or had a name change.
Your Full Retirement Age and Your Primary Insurance Amount
Your full retirement age depends on the year you were born. If you were born between 1943 and 1954, your full retirement age is 66. If you were born between 1955 and 1960, it falls between 66 and 67. If you were born in 1960 or later, your full retirement age is 67. This is the age at which the SSA considers you may have access to to your full calculated benefit with no reduction.
The Primary Insurance Amount (PIA) is the monthly payment you would receive if you claim at your full retirement age. This is the number the SSA uses as the starting point for all other benefit calculations. If you claim earlier, your monthly payment is reduced. If you claim later, your monthly payment is increased. Your PIA itself does not change — only the percentage of it that you receive each month changes based on when you claim.
The SSA does not publish the exact formula it uses to calculate your PIA, but it is progressive: it replaces a higher percentage of lower lifetime earnings than it does of higher earnings. This means two people with very different career earnings will have benefits that are closer together than their earnings were. The formula also changes yearly to account for wage growth in the economy.
How Claiming Age Changes Your Monthly Payment
The age at which you claim Social Security has the largest effect on your monthly benefit. You can claim as early as 62, but each year you claim before your full retirement age, your monthly payment is reduced by a percentage set by law. If your full retirement age is 67 and you claim at 62, your benefit is roughly 30 percent lower than your PIA. If you claim at 65, it is roughly 13 percent lower. These percentages are fixed by law and do not change.
If you delay claiming past your full retirement age, your benefit increases by 8 percent for each year you wait, up to age 70. This means if your full retirement age is 67 and you wait until 70, your monthly benefit is roughly 24 percent higher than your PIA. If your full retirement age is 66 and you wait until 70, your benefit is roughly 32 percent higher. After age 70, your benefit no longer increases, so there is no financial reason to delay past that point.
The table below shows how your monthly benefit changes based on when you claim, using a hypothetical PIA of $2,000 and a full retirement age of 67:
| Claim Age | Percentage of PIA | Monthly Payment |
|---|---|---|
| 62 | 70% | $1,400 |
| 65 | 86.7% | $1,734 |
| 67 (Full Retirement Age) | 100% | $2,000 |
| 70 | 124% | $2,480 |
Where to Find Your Benefit Estimate
The SSA provides a free estimate of your benefit through your my Social Security account. To create an account, go to ssa.gov and click "Create an account" under the my Social Security section. You will need to verify your identity using information from your Social Security card, driver's license or state ID, and tax records. The process takes a few minutes and is done entirely online.
Once you are logged in, you can see your earnings record and a benefit estimate. The estimate shows what you would receive if you claim at 62, at your full retirement age, and at 70. It also shows estimates for your spouse and children if you have them, since they may be may have access to to benefits on your record. The estimate is based on the SSA's records as of the date you view it, so if you have worked since your last login, the estimate may be slightly out of date.
If you do not want to create an online account, you can request a benefit estimate by mail. Call the SSA at 1-800-772-1213 and ask for form SSA-7050-F, or read it from ssa.gov. Mail the completed form to your local Social Security office. The SSA will mail you an estimate within two weeks.
Factors That Reduce or Increase Your Benefit
Several life events can change the benefit amount you receive. If you work while receiving Social Security before your full retirement age, your benefit is reduced by $1 for every $2 you earn above an annual limit. For 2024, that limit is $23,400, but it changes yearly. Once you reach your full retirement age, there is no earnings limit — you can work and receive your full benefit.
If you are married, you may be may have access to to a spousal benefit based on your spouse's earnings record. A spousal benefit is typically up to 50 percent of your spouse's PIA, but only if you claim at your full retirement age. If you claim earlier, the spousal benefit is reduced along with your own benefit. If your spouse has not yet claimed, you may still be able to claim a spousal benefit if you are at least 62 and have been married for at least two years.
If you are divorced, you may be may have access to to a benefit based on your ex-spouse's earnings record if you were married for at least 10 years, are at least 62, and are not currently married. This benefit does not reduce your ex-spouse's benefit and does not require their permission or knowledge. The amount is calculated the same way as a spousal benefit.
Understanding Cost-of-Living Adjustments
Once you start receiving Social Security, your monthly benefit is adjusted each year for inflation through a Cost-of-Living Adjustment (COLA). The COLA is based on the Consumer Price Index and is announced each October for the following year. In years when inflation is low, the COLA may be very small or even zero. In years when inflation is high, the COLA is larger.
The COLA applies to your benefit amount, not to the percentage of your PIA you receive. This means if you claimed early and received a reduced benefit, the COLA increases that reduced amount, not your full PIA. Over time, the gap between what you receive and what you would have received at full retirement age narrows, but it never closes. The reduction you accepted by claiming early is permanent.
Frequently Asked Questions
Can I see my Social Security benefit estimate without creating an online account?
Yes. Call the SSA at 1-800-772-1213 and request form SSA-7050-F, or read it from ssa.gov. Mail the completed form to your local Social Security office, and the SSA will mail you an estimate. The process takes about two weeks. Creating an online account is faster and gives you access to your estimate anytime.
What happens to my benefit if I did not work for 35 years?
The SSA counts any missing years as zero when calculating your average earnings. If you worked 30 years, the five missing years are treated as $0 earnings, which lowers your average and reduces your benefit. There is no way to remove these zero years, but you can add higher-earning years if you continue working past 35 years — the SSA will drop your lowest-earning years from the calculation.
If I claim at 62, can I change my mind and wait until 70?
You can withdraw your claim within 12 months of starting benefits and repay what you received, which restores your benefit to the higher amount you would have received at a later age. After 12 months, you cannot withdraw your claim. You can suspend your benefits at your full retirement age and let them grow until 70, but you must have already started receiving benefits to do this.
Does my benefit change if I get married or divorced after I start receiving Social Security?
Your own benefit amount does not change, but you may become may have access to to a spousal or ex-spousal benefit. A spousal benefit is based on your spouse's earnings record and is added to your own benefit. An ex-spousal benefit works the same way if you were married for at least 10 years. Contact the SSA to report a marriage or divorce and learn about you are may have access to to an additional benefit.
How do I know if the SSA has the correct earnings in my record?
Log into your my Social Security account and review your earnings record year by year. Compare it to your tax returns or W-2 forms. If you spot an error, contact the SSA right away — you generally have three years, three months, and 15 days from the end of the year in which you earned the money to correct it. Errors are more common for self-employed workers and people who changed jobs frequently.
