Social Security Benefit Estimator (rough)

Rough estimate of monthly Social Security retirement benefit based on AIME → PIA → claiming-age adjustment. For precise figure use ssa.gov "my Social Security".

Inputs

Roughly your highest-35-years average monthly wages (indexed for inflation). 2024 US median ~$4,800; high earners $10k+. Cap = $176,100/yr (2025 SS wage base) = ~$14,675/mo top.

62 = earliest; 67 = Full Retirement Age (born 1960+); 70 = max delayed-retirement credit.

Determines Full Retirement Age (FRA): 1943-1954 = 66; 1955-1959 = 66 + 2mo per year; 1960+ = 67.

How to use this calculator

  • Find AIME from ssa.gov "my Social Security" account → "Estimated Benefits" → "View earnings record" (your actual indexed figure).
  • Or estimate AIME yourself: highest 35 years of earnings, inflation-indexed, divided by 420 months.
  • Enter birth year so FRA is computed correctly.
  • Try several claim ages (62 / 67 / 70) to see the trade-off.

About this calculator

A rough estimate — for the precise figure log into ssa.gov "my Social Security" with your actual earnings record. Social Security retirement benefit = Primary Insurance Amount (PIA) × claim-age adjustment factor. PIA is computed from AIME (Average Indexed Monthly Earnings — your highest 35 inflation-indexed years averaged into a monthly figure) using the SSA "bend points" formula: 90% of the first $1,226, plus 32% of the next $6,165 (up to $7,391), plus 15% of anything above. The bend points are recalculated annually for inflation; the values here are 2025 vintage and shift slightly each year. Claiming before Full Retirement Age (FRA) reduces benefits by 5/9 of 1% per month for the first 36 months early, then 5/12 of 1% per month for any earlier months — claiming at 62 vs 67 (5 years early, all in the first 36 mo + 24 mo beyond) gives ~30% lower benefits, permanently. Claiming after FRA earns an 8% per year Delayed Retirement Credit up to age 70 — claiming at 70 vs 67 boosts benefits by 24%. The math is the same percentage applied to a smaller starting amount.

Frequently asked

What is "Full Retirement Age" (FRA)?+
The age at which you receive 100% of your PIA. Per the Social Security Amendments of 1983: 66 for those born 1943-1954; 66 + 2 months per birth-year for 1955-1959; 67 for everyone born 1960+. There's no further scheduled increase, though Congress periodically debates raising it.
Should I claim at 62?+
Permanent ~30% reduction vs FRA. Only makes sense if (a) you genuinely need the income, (b) you expect a shorter-than-average lifespan, or (c) you have a spouse who can claim spousal benefit (the math gets complex). Most analyses (SSA Office of Retirement Policy 2023) favor claiming at 67-70 for typical life expectancy.
Should I delay to 70?+
Each year past FRA adds 8% (32% total if FRA is 67 and you wait 3 more years). Mathematically: break-even age ~82-83 — i.e., if you live past 83, delaying wins; if not, claiming earlier wins. Average US life expectancy at 67 is 84-85, so delay is the default rational choice for healthy retirees.
Why is my estimate different from SSA's?+
Two reasons: (1) this tool uses 2025 bend points, but SSA recomputes them each year for new claimants; (2) AIME requires your actual indexed earnings, which only SSA has. This estimate is typically within 5% of the SSA figure for normal earners.
Does this include spousal / survivor benefits?+
No — those are separate calculations. A spouse can claim up to 50% of the higher earner's PIA at THEIR FRA, regardless of own earnings. Surviving spouse can claim up to 100% of the deceased's PIA at THEIR FRA. Use SSA's "Spousal Benefit" tool for these.
