US Social Security Retirement Benefits

Monthly retirement income paid by the US Social Security Administration, based on your lifetime earnings and the age at which you choose to start claiming, between 62 and 70.

Definition

Social Security retirement benefits are monthly payments made by the US Social Security Administration (SSA) to eligible retirees, funded through payroll taxes paid during their working years. Your benefit amount depends on your lifetime earnings history and the age at which you choose to begin claiming, which can range from 62 to 70.

Because the claiming-age decision has a large and permanent effect on your monthly benefit, understanding how the formula works is a core part of US retirement planning.

Formula

Your benefit is derived from your Primary Insurance Amount (PIA), calculated from your Average Indexed Monthly Earnings (AIME) using your highest 35 years of inflation-indexed earnings, applied through progressive "bend point" percentages set annually by the SSA:

PIA = 90% of AIME up to the first bend point + 32% of AIME between bend points + 15% of AIME above the second bend point

Claiming before your Full Retirement Age (FRA) reduces this PIA; claiming after FRA (up to age 70) increases it via delayed retirement credits of roughly 8% per year.

Worked Example

Suppose your PIA (the benefit at your Full Retirement Age of 67) works out to $2,200/month.

Claiming at 62 (5 years early): Reduced by approximately 30% → $1,540/month

Claiming at 67 (FRA): Full PIA → $2,200/month

Claiming at 70 (3 years delayed): Increased by approximately 24% → $2,728/month

The difference between claiming at 62 versus 70 is over $1,100/month for life. Use the Social Security calculator to estimate your own PIA and compare claiming ages based on your earnings record.

Key Things to Know

  • 35 years of earnings matter: If you worked fewer than 35 years, zeros are averaged into your AIME calculation, which can meaningfully lower your benefit — working a few extra years can sometimes replace a zero-earning year and boost your PIA.
  • Social Security complements other retirement income: Most financial plans treat Social Security as one leg of a three-legged stool alongside employer plans like a 401(k) and personal savings like a Roth IRA.
  • Spousal and survivor benefits exist: A spouse can claim up to 50% of the higher earner's PIA, and a surviving spouse can claim up to 100%, which affects optimal claiming strategy for couples.
  • The earnings test only applies before FRA: If you claim early and continue working, benefits may be temporarily withheld above an earnings threshold, but this withholding is credited back as a higher benefit once you reach FRA.
  • Social Security is not the same as an RMD: Social Security benefits are not tied to an account balance or life expectancy factor — the formula and rules are entirely separate from retirement account withdrawal requirements.

Frequently Asked Questions

You can claim as early as age 62, but your monthly benefit is permanently reduced for claiming before your Full Retirement Age (FRA), which is 66-67 depending on your birth year. Delaying past FRA, up to age 70, increases your benefit by roughly 8% per year through delayed retirement credits.
The Social Security Administration calculates your Average Indexed Monthly Earnings (AIME) from your highest 35 years of earnings, then applies a progressive bend-point formula to determine your Primary Insurance Amount (PIA) — the benefit you'd receive at Full Retirement Age. Claiming earlier or later than FRA then adjusts that PIA up or down.
Up to 85% of your Social Security benefits can be subject to federal income tax if your combined income (adjusted gross income plus nontaxable interest plus half your Social Security benefits) exceeds certain thresholds. Many states also exempt Social Security from state income tax, though rules vary.
If you claim before Full Retirement Age and continue working, the Social Security earnings test temporarily withholds $1 in benefits for every $2 you earn above an annual limit (adjusted yearly). Once you reach FRA, this withholding stops and your benefit is recalculated upward to credit back the withheld amounts.
Claiming at 62 gives you more years of payments but a permanently lower monthly amount, while waiting until 70 maximizes your monthly benefit through delayed retirement credits but means fewer total years of payments. The right choice depends on your health, other income sources, and break-even analysis — use the Social Security calculator to compare scenarios.
