Your payment amount depends on your earnings history and the age you start collecting

Social Security calculates your payment based on how much you earned during your working years and when you claim. The Social Security Administration (SSA) looks at your 35 highest-earning years, adjusts them for inflation, and uses that average to set your Primary Insurance Amount (PIA) — the base payment you receive at your full retirement age. If you claim before full retirement age, your payment is reduced. If you delay past full retirement age, it increases by about 8 percent per year until age 70.

The exact formula SSA uses applies bend points — dollar thresholds that determine what percentage of your average earnings becomes your benefit. These bend points change each year based on national wage growth. A person who earned $30,000 per year will see a different percentage of those earnings converted to a benefit than someone who earned $120,000 per year.

Key Takeaways

  • Your payment is based on your 35 highest-earning years, adjusted for inflation, not your total lifetime earnings.
  • Claiming at 62 reduces your payment permanently; claiming at 70 increases it permanently compared to claiming at your full retirement age.
  • Your full retirement age depends on your birth year and ranges from 66 to 67 for people born after 1954.
  • Spousal and survivor benefits are calculated separately and may be available even if you have no work history of your own.
  • You can view your estimated payment on your Social Security account at ssa.gov before you claim.

How the 35-year earnings record works

SSA counts your earnings from age 21 forward, but only includes your 35 highest-earning years in the calculation. If you worked fewer than 35 years, SSA counts zeros for the missing years, which lowers your average. This is why someone who took time out of the workforce — for caregiving, illness, or unemployment — may have a lower benefit than someone with 35 consecutive years of earnings.

Years with zero earnings are included in the average only if you have fewer than 35 working years. Once you have 35 years on record, additional work can only increase your benefit if that year's earnings are higher than one of your lowest 35 years. For example, if your 35th-lowest year was $25,000 and you earn $40,000 in a new year, that new year replaces the $25,000 year and raises your average.

SSA adjusts all your historical earnings for inflation using a national wage index. This means your 1990 earnings are not compared dollar-for-dollar to your 2020 earnings; instead, they are adjusted so the comparison is fair. Only your most recent year or two of earnings are not adjusted for inflation.

Full retirement age and how it affects your payment

Your full retirement age is the age at which you can receive 100 percent of your calculated benefit. This age depends on your birth year. People born in 1943–1954 have a full retirement age of 66. People born in 1955 have a full retirement age of 66 and 2 months, and this increases by 2 months for each birth year until 1960, when it reaches 67. Anyone born in 1960 or later has a full retirement age of 67.

If you claim before full retirement age, your payment is reduced permanently. Claiming at 62 — the earliest age you can claim — results in a reduction of about 30 percent if your full retirement age is 67. The reduction is smaller if your full retirement age is 66, but it is still permanent. This reduced amount becomes your new baseline for the rest of your life, including any cost-of-living adjustments.

If you delay claiming past full retirement age, your payment increases by about 8 percent per year until age 70. After 70, there is no additional increase for waiting longer. The decision of when to claim involves comparing how much you will receive over your lifetime, which depends partly on how long you live — information no one can know in advance.

Spousal and survivor benefits use a different calculation

If you are married, divorced, or widowed, you may be may have access to to a benefit based on your spouse's or ex-spouse's earnings record, even if you did not work. A spousal benefit is typically up to 50 percent of the worker's Primary Insurance Amount, though the exact amount depends on your age when you claim and your full retirement age.

A survivor benefit — paid to a widow, widower, or child after a worker dies — is calculated from the worker's PIA but divided among all may be able to access family members. If a worker's PIA is $2,000 per month and three family members are may have access to to survivor benefits, each does not automatically receive $2,000; instead, the total family benefit (usually 75 to 180 percent of the worker's PIA) is split among them.

Divorced spouses can claim on an ex-spouse's record if the marriage lasted at least 10 years, you are at least 62, and you are not currently married. The ex-spouse does not have to have claimed yet, though you must wait until they are at least 62 before you can claim on their record.

Government pension offset and windfall elimination provision

Two rules can reduce your Social Security benefit if you also receive a pension from work not covered by Social Security — typically government employment. The Government Pension Offset (GPO) reduces spousal or survivor benefits by two-thirds of your non-covered pension. The Windfall Elimination Provision (WEP) reduces your own Social Security benefit if you have a non-covered pension.

These rules apply only if your government job did not withhold Social Security taxes. Most government employees hired after 1983 do pay Social Security taxes and are not affected. If you worked for a state or local government, a school district, or a foreign government and did not pay Social Security taxes on that job, check whether WEP or GPO applies to you before you claim.

Cost-of-living adjustments happen once per year

Each January, Social Security increases all benefits by a percentage set by the Cost-of-Living Adjustment (COLA). This adjustment is based on inflation measured by the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). In years with no inflation or deflation, there is no COLA increase.

The COLA applies to your entire benefit amount — your base payment plus any increases from delayed claiming or spousal adjustments. It does not change the formula used to calculate your benefit; it simply multiplies your current payment by the adjustment percentage. The COLA is announced in October and takes effect in January.

How to see your estimated payment before you claim

You can create a my Social Security account at ssa.gov to view your earnings record and see an estimate of your benefit at different claiming ages. The estimate assumes you will continue working at your current pace until you claim. If you plan to retire earlier or later, or if your earnings are expected to change, the estimate may not be accurate.

You can also request a detailed benefit statement by mail if you do not have an online account. SSA will mail you a statement showing your earnings history, your full retirement age, and estimates at ages 62, full retirement age, and 70. This statement is free and takes about two weeks to arrive.

If you find an error in your earnings record — a missing year, an incorrect amount, or earnings credited to the wrong person — report it to SSA as soon as you notice it. You have a limited time to correct errors, and mistakes can significantly affect your benefit amount.

Frequently Asked Questions

Does working after I start collecting Social Security reduce my payment?

If you are below full retirement age, SSA withholds $1 in benefits for every $2 you earn above an annual limit (the limit changes yearly). In the year you reach full retirement age, the withholding is $1 for every $3 earned, but only for earnings before the month you reach full retirement age. Once you reach full retirement age, you can earn any amount without reduction.

Can I increase my Social Security payment after I start collecting?

If you claimed before full retirement age, you cannot increase your payment by waiting longer. However, if you are still working and earning more than your lowest 35 years, your benefit may increase automatically each year as higher-earning years replace lower ones. You do not need to do anything; SSA recalculates automatically.

What if I have very few working years?

You need at least 40 credits to receive your own Social Security benefit; this typically requires about 10 years of work. If you have fewer than 10 years, you cannot claim on your own record, but you may still be may have access to to a spousal or survivor benefit if you are married or widowed.

Does my marital status affect my payment amount?

Your own benefit is based only on your earnings history, not your marital status. However, you may be may have access to to an additional spousal benefit if you are married, or a survivor benefit if your spouse dies. These are separate from your own benefit and have their own rules and calculations.

How far back does Social Security look at my earnings?

Social Security looks at all your earnings from age 21 onward, but uses only your 35 highest-earning years. Earnings before age 21 are not counted. If you worked before age 21, those years do not count toward your 35-year average or your 40-credit requirement.
