What Is Social Security?
Social Security is a federal program that provides financial support to retirees, people with disabilities, and eligible family members. For most Americans, it represents a significant source of income in retirement — making it one of the most consequential financial decisions you'll ever make.
Your benefit amount is based on your earnings history — specifically, your highest 35 years of indexed earnings. The Social Security Administration (SSA) calculates your Primary Insurance Amount (PIA), which is the benefit you'd receive at your full retirement age (FRA).
What Is Full Retirement Age?
Your Full Retirement Age (FRA) depends on your birth year:
| Birth Year | Full Retirement Age |
|---|---|
| 1943–1954 | 66 |
| 1955–1959 | 66 + 2 months per year |
| 1960 and later | 67 |
You can begin claiming benefits as early as age 62 or delay as late as age 70. The age you choose has a significant impact on your monthly benefit.
Early, Full, or Delayed: How Timing Affects Your Benefit
Claiming Early (Age 62)
Claiming at 62 gives you benefits sooner, but your monthly payment is permanently reduced — by as much as 25–30% compared to your FRA benefit. This may make sense if you have health concerns, a shorter life expectancy, or pressing financial needs. However, if you live into your 80s or beyond, early claiming often means receiving significantly less over your lifetime.
Claiming at Full Retirement Age
Claiming at your FRA means you receive your full calculated benefit with no reduction. This is often a solid baseline for comparison.
Delaying Until 70
For every year you delay beyond your FRA (up to age 70), your benefit increases by approximately 8% per year. Someone with an FRA of 67 who waits until 70 could receive benefits roughly 24% higher than if they had claimed at FRA. If you're in good health and have other income sources to draw from, delaying can pay off substantially.
Spousal and Survivor Benefits
Social Security isn't just for individual workers. Important benefits for families include:
- Spousal benefits: A spouse may be eligible for up to 50% of the higher-earning spouse's FRA benefit, even with limited work history.
- Survivor benefits: If a spouse passes away, the surviving spouse can claim the deceased's full benefit amount, which is especially valuable if the higher earner delayed claiming.
- Divorced spouse benefits: If you were married for at least 10 years, you may be eligible for benefits based on your ex-spouse's record without affecting their benefits.
Taxes and Social Security
Depending on your combined income (including other retirement income and half of your Social Security benefits), a portion of your benefits may be subject to federal income tax:
- Up to 50% of benefits may be taxable if your combined income is between $25,000–$34,000 (single) or $32,000–$44,000 (married filing jointly)
- Up to 85% may be taxable if above those thresholds
Some states also tax Social Security income, so check your state's rules as well.
