Social Security Benefit Estimator
When you claim Social Security changes your monthly benefit by a lot — claiming at 62 instead of your full retirement age can permanently cut your benefit by around 30%, while delaying to 70 can boost it by roughly the same amount in the other direction. This calculator uses the real 2026 benefit formula (the same bend-point structure the Social Security Administration uses) to estimate your monthly benefit at different claiming ages, so you can see the trade-off in real numbers.
This is a proxy for your official “AIME” (Average Indexed Monthly Earnings) — your 35 highest-earning years, wage-indexed. If you don’t know your exact AIME, estimate your career-average monthly income here.
How the Real Benefit Formula Works
Social Security’s Primary Insurance Amount (PIA) formula is deliberately progressive: for workers becoming eligible in 2026, it pays 90% of your first $1,286 in average monthly earnings, 32% of earnings between $1,286 and $7,749, and just 15% of anything above that. This structure replaces a much larger share of income for lower earners than higher earners — someone earning $2,000/month on average gets a far higher percentage of that back in benefits than someone earning $10,000/month, even though the higher earner’s dollar benefit is larger.
Why Claiming Age Matters So Much
Claiming before your Full Retirement Age (67 for anyone born 1960 or later) permanently reduces your benefit — 5/9 of 1% for each of the first 36 months early, then 5/12 of 1% for any additional months, adding up to roughly a 30% cut at age 62. Delaying past FRA works in your favor: each month you wait adds 2/3 of 1% (8% per year), up to age 70, when the credits stop. There’s no single “right” age — it depends on health, other income, and how long you expect to live — but the dollar gap between claiming at 62 versus 70 is large enough that it’s worth running the numbers before deciding.
A Few Practical Notes
The real AIME calculation uses your actual 35 highest wage-indexed earning years from your SSA earnings record — this calculator instead asks for a simple career-average monthly earnings estimate as a practical stand-in, which is a simplification most public calculators also use since few people know their exact AIME offhand. This estimator also assumes a Full Retirement Age of 67, correct for anyone born in 1960 or later; those born earlier have a slightly lower FRA.
