AIME $6,000 → PIA $2,665.80. The exact SSA math, not a black box.
Most Social Security calculators are black boxes — this one runs the statute. Enter your AIME (your SSA statement shows it) and watch the 2026 bend-point formula produce your exact Primary Insurance Amount: 90% of the first $1,286, 32% up to $7,749, 15% above, rounded down to the dime. Then see what claiming at 62 versus 70 does to the same earnings record — a 77% difference.
Anyone within a decade of claiming uses it to see the statute itself: AIME through the 2026 bend points ($1,286/$7,749), rounded down to the dime, then the exact −30% to +24% swing between claiming at 62 and 70 — the number the SSA estimator shows without the formula.
Three steps. SSA indexes your 35 highest-earning years and averages them into AIME (missing years count as zero). Then the bend-point formula: for those turning 62 in 2026, PIA = 90% of the first $1,286 of AIME + 32% of AIME between $1,286 and $7,749 + 15% above $7,749, rounded down to the nearest dime. Example: AIME $6,000 → $1,157.40 + $1,508.40 = PIA $2,665.80. Finally your claiming age adjusts it: at 62 you get $1,866 (−30%), at 70 you get $3,305.59 (+24%).
$1,286 and $7,749 for workers first eligible in 2026 (the year you turn 62) — up from $1,226 and $7,391 for 2025 eligibility. They are set by your year of first eligibility and locked for life; later COLAs adjust the benefit itself instead. The 2026 maximum possible PIA is $4,216.90 (AIME $14,358 — a full career at the taxable maximum, which is $184,500 of earnings in 2026).
The formula is progressive by design: the 90% first band means an AIME of $2,000 gets 69.3% of income replaced, while AIME $8,000 replaces only 40.8%. High earners still get larger checks in dollars, but a smaller share of what they paid in. This is also why the 15% top band exists — and why proposals to fix the trust fund often target that band's bend point rather than the 90% band that shields low earners.
