Your Social Security payment is based on your highest 35 years of earnings, adjusted for inflation, and reduced if you claim before your full retirement age

Social Security does not pay the same amount to everyone. The Social Security Administration (SSA) calculates your benefit by looking at your work history — specifically your highest 35 years of earnings — and adjusting those earnings for inflation to account for wage growth over time. The result is called your Primary Insurance Amount (PIA), and it becomes your full retirement age benefit. If you claim at a different age, your payment goes up or down from that baseline.

The actual dollar amount you receive depends on when you were born, when you claim, and how much you earned during your working years. Someone who earned significantly more will receive a higher benefit than someone who earned less, but the formula is progressive — it replaces a larger percentage of lower earners' income than higher earners' income. If you did not work for 35 years, the SSA counts the missing years as zero, which lowers your average.

Key Takeaways

  • Your benefit is calculated from your highest 35 years of earnings, adjusted for inflation, so gaps in work history lower your payment.
  • Claiming before your full retirement age permanently reduces your monthly payment; claiming after increases it by roughly 8 percent per year.
  • The SSA uses a progressive formula that replaces a higher percentage of lower earners' income than higher earners' income.
  • You can view your estimated benefit on your Social Security account at ssa.gov, which updates each year as you earn more.
  • Your spouse and children may receive benefits based on your record, but those payments do not increase your own benefit.

How the SSA calculates your Primary Insurance Amount

The SSA starts by taking your earnings record for each year you worked and adjusting those amounts to account for wage growth. This adjustment is called wage indexing. Without it, a dollar earned in 1985 would count the same as a dollar earned in 2024, which would not reflect the real value of your work. The SSA indexes your earnings up to age 60, then uses your actual earnings after that.

Next, the SSA identifies your highest 35 years of indexed earnings and calculates your average monthly earnings — called your Average Indexed Monthly Earnings (AIME). If you worked fewer than 35 years, the missing years count as zero, which reduces your average. Once the SSA has your AIME, it applies a formula called the bend points formula. This formula takes a larger percentage of your first dollars of earnings, a smaller percentage of your middle earnings, and an even smaller percentage of your highest earnings. This is why the system replaces a higher percentage of income for lower earners.

The bend points themselves change each year based on national wage trends. For 2024, the bend points are different from 2023, which were different from 2022. The SSA publishes these annually, and they affect how much of each earnings tier gets counted toward your benefit. Your PIA is the result of applying these bend points to your AIME.

What happens if you claim early, at full retirement age, or late

Your full retirement age depends on your birth year. For people born in 1943 through 1954, full retirement age is 66. For those born in 1955, it is 66 and two months. For those born in 1960 or later, it is 67. Your PIA is the amount you receive if you claim at your full retirement age.

If you claim before your full retirement age, your benefit is permanently reduced. The reduction is roughly 6.67 percent per year for the first three years you claim early, and 5 percent per year for each year before that. For example, if your full retirement age is 67 and you claim at 62, you are claiming five years early, so your benefit is reduced by approximately 30 percent for life. This reduction never goes away, even after you reach your full retirement age.

If you delay claiming past your full retirement age, your benefit increases by roughly 8 percent per year until age 70. After 70, there is no additional increase for waiting longer. Someone born in 1960 with a PIA of $2,000 at age 67 would receive roughly $2,640 per month if they waited until age 70, but only $1,400 if they claimed at 62. These adjustments are called early claiming reductions and delayed retirement credits.

How work history affects your payment amount

Every year you work and earn income, the SSA adds that year to your record. If the new year's earnings are higher than one of your previous 35 years, the SSA replaces the lower year with the new one, and your benefit increases. This is why people who continue working past full retirement age often see their benefits go up — the SSA recalculates using your new, higher earnings.

Conversely, if you have years with no earnings or very low earnings, those years count as zero in your 35-year average. Someone who took time out of the workforce for caregiving, unemployment, or other reasons will have lower benefits than someone with 35 years of continuous work at the same wage level. The SSA does not exclude these years; it includes them as zero.

If you worked for a government employer and received a pension that was not funded by Social Security taxes, you may be subject to the Government Pension Offset (GPO) or the Windfall Elimination Provision (WEP). These rules can reduce your Social Security benefit. WEP affects your own benefit if you have a non-covered government pension; GPO affects spousal or survivor benefits. These are complex rules that depend on your specific situation.

Spousal and family benefits based on your record

Your spouse, ex-spouse, and children may be able to receive benefits based on your Social Security record. A spouse at full retirement age can receive up to 50 percent of your PIA; a spouse who claims early receives less. Children under 19 (or 19 if still in high school) can receive up to 50 percent of your PIA each. An ex-spouse can receive benefits on your record if you were married for at least 10 years, you are both at least 62, and you have been divorced for at least two years (or any length of time if you are both 62 or older).

The important point is that family members' benefits do not reduce your own benefit. If your spouse receives 50 percent of your PIA, you still receive 100 percent of your PIA. However, there is a family maximum — the total amount that can be paid to all family members on your record is typically 150 to 180 percent of your PIA. If the family maximum is reached, each family member's benefit is reduced proportionally.

How to find your estimated benefit amount

The SSA provides a free online account at ssa.gov where you can view your estimated benefit at different claiming ages. You will need to create a login using your email address and verify your identity. Once you are logged in, you can see your earnings record, check for errors, and view estimates for claiming at 62, your full retirement age, and 70.

These estimates are based on the assumption that you will continue earning at your current rate until you claim. If your earnings change significantly, or if you stop working, your actual benefit may differ. The SSA updates your estimate each year after you file your taxes, so checking your account annually is a good practice. If you do not have internet access or prefer to speak with someone, you can call the SSA at 1-800-772-1213 to request a benefit estimate by mail.

Cost-of-living adjustments and how they affect your payment

Once you start receiving Social Security, your benefit is adjusted annually for inflation through a Cost-of-Living Adjustment (COLA). The COLA is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) and is announced in October for the following year. In years when inflation is low, the COLA may be small or zero. In years when inflation is high, the COLA is larger.

The COLA applies to everyone receiving Social Security — retirees, disabled workers, and survivors. It does not change the formula used to calculate your benefit; it simply increases the dollar amount you receive each month. For example, if you receive $2,000 per month and the COLA is 3.2 percent, your new payment would be $2,064 per month. The COLA is applied to your benefit amount, not to your PIA, so it compounds over time.

Frequently Asked Questions

Does working longer always increase my Social Security benefit?

Working longer increases your benefit only if your new year's earnings are higher than one of your lowest 35 years on record. If you continue earning at the same level or lower, your benefit will not increase. However, if you claim early and continue working, your benefit is reduced by $1 for every $2 you earn above the annual earnings limit (which changes yearly), so working while claiming early can actually lower your total income.

What if I have gaps in my work history?

Gaps count as zero in your 35-year average, which lowers your benefit. The SSA does not exclude these years or give you credit for caregiving, military service, or other non-work periods. However, if you have fewer than 35 years of work, you may still may have access to for benefits — you need only 40 work credits, which is roughly 10 years of work, to be insured for retirement benefits.

Can I change my claiming age after I start receiving benefits?

You can withdraw your claim within 12 months of starting benefits and repay what you received, which resets your claiming age. After 12 months, you cannot withdraw. You can request a one-time increase if you delay claiming, but the rules are strict. Talk to the SSA directly about your options if you are considering a change.

How much does my spouse receive based on my record?

A spouse at full retirement age receives up to 50 percent of your PIA. A spouse who claims before full retirement age receives less — the reduction depends on how many months early they claim. A spouse caring for a child under 16 can receive 75 percent of your PIA regardless of age. These amounts do not reduce your own benefit.

Will my benefit change if I move to another country?

Social Security benefits are generally payable anywhere in the world, but some countries have restrictions. If you move, notify the SSA so they can update your address and ensure your payments continue. Some countries do not have a Social Security agreement with the United States, which can affect payment methods, so check with the SSA before you move.
