About this calculator
The result is your estimated annual benefit (12 × the monthly amount). It follows the Social Security Administration's benefit formula with 2026 figures. Average Indexed Monthly Earnings (AIME) = your average annual earnings over your 35 highest years (capped at the 2026 taxable maximum of $184,500) ÷ 12; if you worked fewer than 35 years, the missing years count as zeros, so AIME is scaled by years ÷ 35. The Primary Insurance Amount (PIA, your benefit at full retirement age) = 90% of AIME up to $1,286 + 32% of AIME from $1,286 to $7,749 + 15% of AIME above $7,749 (the 2026 bend points), capped at $4,152, the 2026 maximum at full retirement age. Full retirement age is 67 for anyone born in 1960 or later. Claiming early cuts the benefit by 5/9 of 1% per month for the first 36 months and 5/12 of 1% per month beyond that (62 → 70% of PIA, 65 → 86.67%); delaying past 67 adds 2/3 of 1% per month (8% a year) up to 70 (124%). Enter earnings already adjusted for wage growth (your SSA statement shows indexed earnings); using raw past salaries understates the benefit. Not modeled: spousal and survivor benefits, the earnings test if you work while claiming early, cost-of-living increases after 2026, and taxes on benefits.
How to use
Suppose you earn an average of $70,000/year (wage-indexed), have worked 30 years, and plan to retire at 67. Step 1 — AIME: $70,000 ÷ 12 × 30/35 = $5,000. Step 2 — PIA: 90% × $1,286 + 32% × ($5,000 − $1,286) = $2,345.88/month. Step 3 — At 67: $2,345.88 × 12 = $28,150.56/year. If you retired at 62 instead (70%): $19,705.39/year (~$1,642/month). Delaying to 70 (124%): $34,906.69/year (~$2,909/month).
Frequently asked questions
How does retiring early at 62 affect my Social Security benefits?
Claiming Social Security at 62 permanently reduces your monthly benefit to 70% of what you would receive at your full retirement age (67 for those born in 1960 or later). This reduction exists because you will collect payments over a longer period. Over a short retirement horizon the total may be similar, but if you live past your mid-80s, delaying typically results in greater lifetime benefits. You should weigh your health, other income sources, and break-even age before deciding.
Why do fewer than 35 years of work reduce my Social Security benefit?
The Social Security Administration calculates your benefit using your 35 highest-earning years. If you worked fewer than 35 years, zero-income years are included in the average, which lowers your Average Indexed Monthly Earnings (AIME). Each missing year acts as a drag on the calculation. Working even a few additional years — especially at a higher salary — can meaningfully boost your projected benefit.
What is the maximum Social Security benefit I can receive in retirement?
The Social Security taxable earnings cap sets a ceiling on credited earnings — $184,500 in 2026. No matter how much you earn above this threshold, the excess does not increase your benefit. To receive the maximum you would need earnings at or above the cap in all 35 of your highest-earning years. For 2026 the maximum monthly benefit is $4,152 at full retirement age (about $49,800 a year), and higher if you delay claiming to 70.
