Your benefit is based on your earnings record, not on how much you need

Social Security calculates your monthly benefit using a formula that looks at your highest 35 years of earnings. The Social Security Administration (SSA) adjusts those earnings for inflation, adds them up, and then applies a formula that gives you a larger percentage of your early earnings and a smaller percentage of your later ones. Your age when you start collecting also changes the amount — claiming at 62 gives you less per month than claiming at 67 or 70, because the SSA expects to pay you for more years overall.

The calculation is the same whether you are claiming retirement, disability, or survivor benefits. What changes is when you become able to claim and whether your benefit can be reduced because of other income you earn. The SSA does not look at your savings, your home, or whether you are struggling financially. It looks only at what you paid into the system through payroll taxes.

Key Takeaways

  • Your benefit amount depends on your 35 highest-earning years, adjusted for inflation, not on your current need or savings.
  • Claiming at 62 gives you a smaller monthly payment than waiting until 67 or 70, because you will receive benefits for more years.
  • You can see your actual earnings record and an estimate of your future benefit by creating an account at ssa.gov.
  • If you worked outside the United States or for a government employer, different rules may reduce your benefit.
  • Your benefit amount stays the same each year except for cost-of-living adjustments, which the SSA announces each October.

The 35-year earnings history and how inflation adjusts it

The SSA looks back at your entire work history and selects your 35 highest-earning years. If you worked fewer than 35 years, the SSA counts the missing years as zero, which lowers your average. This is why people who took time out of the workforce — for caregiving, illness, or unemployment — often see a lower benefit than someone who worked continuously.

The SSA does not use your actual dollar amounts from 1985 or 1995. Instead, it adjusts each year's earnings to what they would be worth in the year you turn 60, using a national wage index. This means your early-career earnings are scaled up to account for inflation and wage growth, so a year you earned $20,000 in 1990 might be counted as $45,000 in today's terms. Only your earnings up to the Social Security wage base count — in 2024, that cap is $168,600, so earnings above that are ignored.

Once the SSA has your 35 adjusted earnings years, it divides the total by 420 (the number of months in 35 years) to get your Average Indexed Monthly Earnings, or AIME. This number is the foundation for everything that follows.

The bend points formula that determines your monthly amount

The SSA then applies a formula with two "bend points" — dollar thresholds where the percentage changes. For someone turning 62 in 2024, the formula is roughly: 90 percent of the first $1,174 of your AIME, plus 32 percent of earnings between $1,174 and $7,078, plus 15 percent of anything above $7,078. These bend points change each year based on wage growth.

This formula is why Social Security replaces a higher percentage of low-income workers' earnings than high-income workers' earnings. A person whose AIME is $1,500 gets about 82 percent of that amount as a benefit. A person whose AIME is $6,000 gets about 42 percent. The system is designed to provide a foundation of income for everyone, with a larger cushion for those who earned less.

The result of this formula is your Primary Insurance Amount, or PIA. This is the benefit you would receive if you claimed at your full retirement age — currently 67 for people born between 1943 and 1954, and gradually rising to 67 for those born in 1960 or later.

How your claiming age changes your monthly payment

If you claim before your full retirement age, your benefit is reduced by a percentage that depends on how many months early you claim. Claiming at 62 — the earliest possible age — reduces your benefit by about 30 percent compared to claiming at 67. The reduction is permanent; you do not get a higher payment later to make up for it.

If you delay claiming past your full retirement age, your benefit increases by 8 percent per year until age 70. Someone born in 1957 with a full retirement age of 67 and a PIA of $2,000 would receive about $1,400 per month at 62, $2,000 at 67, or $2,480 at 70. The SSA stops the increases at 70, so there is no financial advantage to waiting longer.

The choice of when to claim is personal and depends on your health, life expectancy, whether you are still working, and whether you need the money now. There is no single "right" age for everyone.

Reductions that apply to certain workers

If you worked for a government employer — a state, local, or federal agency — and did not pay Social Security taxes on that job, your Social Security benefit may be reduced under the Government Pension Offset or Windfall Elimination Provision. These rules are complex and depend on when you were born, when you started that government job, and whether you also have a government pension. The SSA can tell you whether either rule affects you.

If you are receiving a pension from work outside the United States, or if you are a non-citizen, additional rules may apply. The SSA website has country-specific information, or you can call 1-800-772-1213 to ask about your situation.

How to see your own earnings record and benefit estimate

You can create a free account at ssa.gov and view your actual earnings record — the year-by-year history the SSA has on file. This is the only way to know for certain whether the SSA has recorded your earnings correctly. If you spot an error, you can report it and the SSA will investigate.

The same account shows you an estimate of your future benefit at different claiming ages. This estimate is based on the assumption that your earnings will stay the same as your recent average. If you plan to work several more years, or if you expect to earn significantly more or less, the estimate will not be exact. But it gives you a realistic range to work with.

If you do not have internet access or prefer to work with someone in person, you can visit a local Social Security office or call 1-800-772-1213 to request a benefit estimate by mail.

Cost-of-living adjustments and how your benefit changes over time

Once you start receiving benefits, your monthly payment stays the same except for cost-of-living adjustments, or COLAs. Each October, the SSA announces the COLA for the following year based on inflation measured by the Consumer Price Index. In recent years, COLAs have ranged from 0 percent (in 2010 and 2011) to 8.7 percent (in 2023). The adjustment is applied to all benefits in January.

COLAs are automatic — you do not have to do anything to receive them. They apply to retirement, disability, and survivor benefits equally. The COLA is the only way your benefit amount increases after you start claiming, aside from rare situations like a correction to your earnings record.

Frequently Asked Questions

Does working longer increase my benefit?

Yes, if your recent earnings are higher than one of your lowest 35 years. The SSA drops your lowest-earning year and replaces it with your new year's earnings. Working longer also delays your claiming age, which increases your monthly payment. However, if your recent earnings are lower than your lowest year on record, working longer can actually lower your benefit.

What if I did not work 35 years?

The SSA counts missing years as zero, which lowers your average. If you worked 30 years, your benefit is calculated using 30 years of earnings and 5 years of zeros. Some people become able to claim a benefit on a spouse's or ex-spouse's record instead, which has different rules and does not require 35 years of your own work.

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

You can withdraw your application within 12 months of claiming and repay all benefits received, which resets your claiming age. After 12 months, you cannot change your age, but you can suspend benefits at your full retirement age and let them grow until 70. The rules are strict, so contact the SSA before making any changes.

How does marriage or divorce affect my benefit?

Your own benefit is based only on your earnings record and does not change because of marriage or divorce. However, you may become able to claim a benefit on a spouse's or ex-spouse's record, which is calculated differently. You must have been married at least 10 years to claim on an ex-spouse's record, and your ex does not need to have claimed yet.

Will my benefit be taxed?

If your total income is above a certain threshold, part of your Social Security benefit may be subject to federal income tax. The thresholds are $25,000 for single filers and $32,000 for married couples filing jointly. Some states also tax Social Security benefits. The SSA sends a form each January showing how much you received, which you use when filing taxes.
