How Do Social Security Benefits Work?
In plain English
Social Security retirement benefits provide monthly income based on your 35 highest-earning years, adjusted for inflation. Your benefit is calculated as a percentage of your Average Indexed Monthly Earnings (AIME) using a progressive formula. The amount you receive depends on when you claim relative to your full retirement age, ranging from 70% (at 62) to 124% (at 70) of your full benefit.
How Are Social Security Benefits Calculated?
The SSA takes your 35 highest-earning years, adjusts them for wage inflation, and averages them to get your AIME. It then applies a progressive benefit formula to calculate your Primary Insurance Amount (PIA) — the benefit you receive at full retirement age. The formula replaces a higher percentage of lower earnings, making Social Security more generous relative to income for lower earners. Checking your SSA statement online shows your projected benefit.
What Factors Can Increase or Decrease Your Benefit?
Working more years increases your benefit by replacing zero-income years in your 35-year average. Earning more raises your AIME. Delaying claiming past FRA increases benefits 8% per year. Conversely, claiming early permanently reduces your benefit, and the Windfall Elimination Provision (WEP) reduces benefits for those with government pensions from non-Social Security-covered jobs. The Government Pension Offset (GPO) affects spousal and survivor benefits.
Are There Benefits for Spouses, Survivors, and Dependents?
Yes. Spouses can receive up to 50% of the other spouse's FRA benefit even with their own limited work history. Survivors can receive up to 100% of a deceased spouse's benefit. Dependent children can receive benefits based on a parent's record. Divorced spouses who were married at least 10 years may also claim benefits on a former spouse's record without reducing that spouse's benefit.
Frequently asked questions
Can I collect Social Security while still working?
Yes, but if you claim before FRA and earn above the annual exempt amount ($22,320 in 2026), your benefit is temporarily reduced by $1 for every $2 above the limit. Once you reach FRA, you can earn any amount without benefit reduction. Benefits withheld early are credited back as a higher monthly payment after FRA.
How do I know what my Social Security benefit will be?
Create an account at ssa.gov/myaccount to view your earnings history and estimated benefits at age 62, FRA, and 70. Review it annually to ensure your earnings are recorded correctly. Any errors can permanently reduce your benefit if not corrected.
