What is Social Security
Social Security is a federal program that provides retirement income, disability benefits, and survivor benefits to eligible workers and their families — funded through payroll taxes during working years and claimed starting as early as age 62.
Social Security is a federal government program administered by the Social Security Administration (SSA) that provides financial benefits to eligible workers and their families. It functions primarily as a retirement income program but also covers disability and survivor benefits. Workers earn credits by paying into the system via payroll taxes (FICA) throughout their careers, and receive monthly payments when they retire, become disabled, or die (with benefits going to eligible dependents).
Social Security is the largest source of income for most American retirees. About 67 million Americans receive benefits each month.
How Social Security Credits Work
To qualify for Social Security, you must earn 40 credits (equivalent to 10 years of work). In 2025, you earn one credit for each $1,810 in covered earnings, up to four credits per year.
Payroll taxes fund the program:
- Employees pay 6.2% of wages (up to the taxable wage base, $176,100 in 2025)
- Employers pay a matching 6.2%
- Self-employed individuals pay both sides (12.4%), though they can deduct half
Full Retirement Age (FRA)
Your Full Retirement Age (FRA) is the age at which you receive 100% of your calculated benefit:
| Birth Year | Full Retirement Age |
|---|---|
| 1943–1954 | 66 |
| 1955–1959 | 66 and 2–10 months |
| 1960 and later | 67 |
When to Claim: The Big Decision
You can claim Social Security as early as age 62 or as late as age 70. The timing has a major permanent impact on your monthly benefit:
- Claim at 62: Benefit is reduced by up to 30% from your FRA amount
- Claim at FRA (67): You receive 100% of your calculated benefit
- Delay past FRA: Benefit grows 8% per year up to age 70
Someone with an FRA benefit of $2,000/month would receive:
- ~$1,400/month at 62 (30% reduction)
- $2,000/month at 67
- $2,480/month at 70 (24% increase)
Over a long retirement, delaying can be worth hundreds of thousands of dollars — but the math depends heavily on life expectancy and other income sources.
How Your Benefit Is Calculated
The SSA calculates your benefit based on your 35 highest-earning years (adjusted for inflation). The formula replaces a higher percentage of lower-income workers' earnings than higher-income workers — meaning Social Security is more important to lower earners both absolutely and as a percentage of pre-retirement income.

Spousal and Survivor Benefits
- Spousal benefit: A spouse who didn't work (or had lower earnings) can claim up to 50% of the working spouse's FRA benefit — whichever is higher, their own or the spousal amount
- Survivor benefit: When a spouse dies, the surviving spouse can receive the deceased's full benefit amount — making the higher earner's decision on when to claim particularly important for couples
Social Security and Taxes
Up to 85% of Social Security benefits can be subject to federal income tax if your "combined income" (AGI + nontaxable interest + half of Social Security) exceeds:
- $25,000 for single filers
- $32,000 for married filing jointly
Most states do not tax Social Security benefits, though 11 states do (with varying exemptions).
Social Security and Retirement Planning
Despite concerns about the program's long-term finances, Social Security provides a foundation most retirees rely on. Key planning considerations:
- Maximize your earning record: 35 years of earnings are used in the calculation; zero-earning years drag the average down
- Coordinate with a spouse: Couples have multiple claiming strategies available
- Don't claim early by default: Many people claim at 62 simply because they can — delaying even a few years can significantly boost lifetime income if you're in good health
- Understand the inflation protection: Social Security benefits include annual cost-of-living adjustments (COLA) — a valuable feature that most other income sources lack
