Social Security Calculator

How This Estimate Is Calculated

The Social Security Administration bases your benefit on your Average Indexed Monthly Earnings (AIME) — roughly your highest 35 years of wage-indexed earnings, averaged and divided by 12. This calculator approximates AIME using the average annual income and number of working years you enter. From AIME, a Primary Insurance Amount (PIA) is calculated using the 2024 bend-point formula: 90% of the first $1,174 of AIME, 32% of AIME between $1,174 and $7,078, and 15% of AIME above that. This PIA is your benefit at Full Retirement Age (FRA). If you have fewer than 35 years of earnings, the shortfall is treated as zero-income years, which lowers your average — a common reason real benefits come in lower than expected.

Why Claiming Age Changes Your Check So Much

Claiming before your FRA permanently reduces your benefit — as much as 30% lower if you claim at 62 instead of an FRA of 67. Delaying past FRA increases it by roughly 8% per year up to age 70, the maximum claiming age. This calculator applies those standard reduction and credit rates so you can see the tradeoff between claiming early for more years of smaller checks versus waiting for a larger, longer-term payout. There's no single right answer — it depends heavily on health, other income, and how long you expect to need the benefit.

Plan Around This Number, Don't Rely on It Alone

Because this is a simplified estimate (the real SSA formula uses your actual year-by-year wage history indexed for national wage growth), treat this figure as a planning baseline rather than an exact prediction — your official Social Security statement at ssa.gov will always be more precise. To see how this benefit fits into your broader retirement income picture alongside savings and investments, try the retirement calculator or the 401(k) calculator.
