Social Security Terms Explained
Plain-English definitions of common terms. No jargon, no confusion — just clear explanations to help you understand your benefits.
Adjusted Gross Income(AGI)
Your Adjusted Gross Income (AGI) is your total income from all sources minus specific deductions like IRA contributions, student loan interest, and alimony payments. This number is important because many tax benefits and exemptions are based on your AGI. You can find your AGI on Line 11 of your federal Form 1040 tax return.
Example: If you earned $75,000 in wages and contributed $5,000 to a traditional IRA, your AGI would be $70,000.
Average Indexed Monthly Earnings(AIME)
The Social Security Administration calculates your Average Indexed Monthly Earnings by taking your 35 highest-earning years, adjusting earlier years for wage inflation, adding them up, and dividing by 420 (the number of months in 35 years). This number is then used to calculate your PIA (Primary Insurance Amount). If you worked fewer than 35 years, zeros are averaged in for the missing years.
Example: If your indexed earnings over 35 years totaled $2.1 million, your AIME would be $5,000 ($2.1M ÷ 420 months).
Break-Even Age
The break-even age is when the total lifetime benefits from claiming later equal what you would have received by claiming earlier. Before this age, the early claimer is ahead; after this age, the person who delayed comes out ahead. Break-even ages typically fall in the late 70s to early 80s depending on your claiming ages being compared.
Example: Comparing claiming at 62 vs. 67: if your break-even age is 78, and you live past 78, you'll receive more total money by having waited until 67.
Cost-of-Living Adjustment(COLA)
Each year, Social Security benefits are adjusted based on increases in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). This Cost-of-Living Adjustment (COLA) helps your benefits keep pace with rising prices. The adjustment is typically announced in October and takes effect in January. In years with low or no inflation, there may be little or no COLA.
Example: If your monthly benefit is $2,000 and the COLA is 2.5%, your new benefit would be $2,050 starting in January.
Delayed Retirement Credits
For each month you delay claiming Social Security past your Full Retirement Age (up to age 70), you earn Delayed Retirement Credits that permanently increase your benefit. The increase is 8% per year (or ⅔% per month) for those born in 1943 or later. These credits are valuable because they're guaranteed and permanent — your higher benefit continues for life and also provides a higher base for survivor benefits.
Example: If your FRA is 67 and your PIA is $2,000, waiting until 70 would give you $2,480/month (24% more) for life.
Early Claiming Reduction
If you claim Social Security before your Full Retirement Age, your benefit is permanently reduced. The reduction is 5/9 of 1% per month for the first 36 months early, then 5/12 of 1% for each additional month. Claiming at 62 (the earliest possible) with a FRA of 67 means a 30% permanent reduction from your PIA.
Example: If your PIA at FRA (67) would be $2,000, claiming at 62 would permanently reduce it to about $1,400/month.
Full Retirement Age(FRA)
Your Full Retirement Age is when you're entitled to receive your full Primary Insurance Amount (PIA) from Social Security. It depends on your birth year: if you were born in 1960 or later, your FRA is 67. For those born between 1943-1959, it ranges from 66 to 66 and 10 months. Claiming before FRA reduces your benefit; waiting past FRA increases it up to age 70.
Example: If you were born in 1960, your FRA is 67. You can claim as early as 62, but your benefit would be reduced by about 30%.
Government Pension Offset (Eliminated)(GPO)
The Government Pension Offset previously reduced spousal or survivor Social Security benefits for people with government pensions from non-covered work. GPO was eliminated by the Social Security Fairness Act (HR82), effective January 2024. It no longer applies to any current or future claims.
Example: Before elimination, a $3,000/month government pension would have eliminated a $1,500 spousal benefit entirely. This offset no longer applies.
Primary Insurance Amount(PIA)
Your Primary Insurance Amount is the monthly benefit you would receive if you claim Social Security at exactly your Full Retirement Age (FRA). It's calculated from your AIME using a formula with 'bend points' that gives lower earners a higher percentage of their earnings replaced. If you claim before FRA, you receive less than your PIA; if you claim after FRA, you receive more.
Example: If your PIA is $2,500, that's what you'd receive monthly by claiming at age 67 (if that's your FRA). Claiming at 62 might reduce it to about $1,750.
Spousal Benefits
A spouse can receive up to 50% of their partner's PIA if they claim at their own Full Retirement Age. You must be married (or divorced but married for at least 10 years) and your spouse must have filed for their own benefits (or you must be divorced). You'll receive the higher of your own benefit or the spousal benefit — not both.
Example: If your spouse's PIA is $3,000, you could receive up to $1,500 as a spousal benefit at your FRA — if that's more than your own benefit.
State Tax on Social Security
While most states don't tax Social Security benefits, 13 states currently do to some extent: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, North Dakota, Rhode Island, Utah, Vermont, and West Virginia. Many of these offer exemptions based on age or income level. Your actual tax depends on your total income and filing status.
Survivor Benefits
When a Social Security recipient (or eligible worker) dies, their surviving spouse can receive survivor benefits. At Full Retirement Age, a widow or widower can receive 100% of the deceased's benefit. Survivor benefits can be claimed as early as age 60 (or 50 if disabled), though claiming early means a reduced benefit. Children under 18 (or 19 if in high school) may also qualify.
Example: If your spouse received $2,800/month and passes away, you could receive that full amount as a survivor benefit at your FRA.
Windfall Elimination Provision (Eliminated)(WEP)
The Windfall Elimination Provision previously reduced Social Security benefits for people who also had pensions from work not covered by Social Security. WEP was eliminated by the Social Security Fairness Act (HR82), effective January 2024. It no longer applies to any current or future claims.
Example: Before elimination, a retired teacher with a state pension might have seen their Social Security benefit reduced by up to $400/month. This reduction no longer applies.
