Wage-indexed average of your highest 35 years.
⚠️ Estimate only. Uses 2026 PIA bend points ($1,226 / $7,391) and 35-year averaging. For your real benefit, log into ssa.gov/myaccount. Spousal, survivor and disability benefits not modelled. Not financial advice.

How Social Security Calculates Your Benefit

The Social Security Administration uses a three-step formula. First, it indexes your earnings each year for wage growth and averages your highest 35 years to get your Average Indexed Monthly Earnings (AIME). Second, it applies a progressive "bend point" formula to AIME to compute your Primary Insurance Amount (PIA):

  • 90% of the first $1,226 of AIME
  • 32% of AIME between $1,226 and $7,391
  • 15% of AIME above $7,391

Third, it adjusts PIA based on the age you actually claim — reduced for early claiming, increased for delayed claiming.

The Wage Base — Why High Earnings Stop Counting

Each year SSA sets a contribution and benefit base (the "wage base") — the annual maximum on earnings subject to the 6.2% FICA Social Security tax. For 2025 it's $176,100; the figure adjusts each January per the national wage index. Three things follow:

  • Earnings above the wage base are not taxed for Social Security.
  • Earnings above the wage base do not count toward your AIME and therefore do not increase your retirement benefit.
  • The maximum possible PIA at FRA in 2026 is roughly $4,194/month — reached by anyone who consistently earns at or above the wage base for 35 years.

If you enter average earnings above the wage base, this calculator automatically caps them and shows a warning explaining what was ignored.

Full Retirement Age (FRA)

FRA depends on your birth year. For people born in 1960 or later, FRA is 67. The SSA calls this "100% of PIA." Anyone born 1943–1954 has FRA 66; in between is 66 plus 2–10 months.

Early vs Delayed Claiming

  • Age 62 (earliest): ~70–75% of PIA — permanent reduction
  • Full Retirement Age: 100% of PIA
  • Age 70 (latest worth waiting for): 124–132% of PIA via Delayed Retirement Credits (8%/year past FRA)

Claiming at 70 instead of 62 typically results in a monthly benefit roughly 76% larger, for life. The "break-even" age (where total cumulative benefits cross over) is around 78 vs 62, and around 82 vs 67.

Strategy for Married Couples

The classic move is to have the higher earner delay to 70 (locks in the maximum survivor benefit, which the lower-earning spouse keeps for life if widowed) and the lower earner claim earlier for cash flow. This combination usually produces the highest total household lifetime benefit unless one spouse has a serious health condition.

Working While Claiming Before FRA

If you claim before FRA and keep working, the SSA withholds $1 of benefits for every $2 earned over $22,320 (2025 figure, adjusts annually). The withheld amount is recovered after FRA in higher monthly cheques — it's not lost — but the cash-flow hit can be significant.

⚠️
Important Note: This calculator is for US Social Security only. Spousal, survivor, ex-spouse, child, and disability benefits use different rules. Up to 85% of benefits can be federally taxable depending on your "combined income." For a binding strategy consult a CFP or use ssa.gov's official Quick Calculator with your actual earnings record.
