From earnings to AIME
SSA generally indexes covered earnings and uses the highest 35 years. Those indexed earnings are averaged over 420 months to produce average indexed monthly earnings, or AIME. Missing years can count as zeros.
The PIA formula
For a worker first eligible in 2026, the primary insurance amount uses three portions of AIME: 90% up to the first bend point, 32% between the bend points, and 15% above the second bend point. The 2026 bend points are $1,286 and $7,749. These amounts are year-specific and can change.
A simple example
If AIME is $2,000, the first portion is 90% of $1,286 and the next portion is 32% of the remaining $714. The resulting PIA is a starting calculation before claiming-age adjustments, COLAs, or family rules.
What changes the check?
Claiming before full retirement age can reduce a retirement benefit; delayed retirement credits can increase it after full retirement age up to age 70. Your earnings record, birth year, work history, and family situation matter. Use your my Social Security estimate rather than a generic calculator.
FAQ
Does everyone use the same bend points?
No. Bend points are tied to eligibility year and are updated under SSA rules.
Is AIME the final monthly check?
No. AIME feeds the PIA formula. Claiming age, COLAs, taxes, Medicare premiums, and family rules may affect the amount you receive.
Where can I verify my estimate?
Review your earnings record and estimate at SSA.gov/myaccount.

Bottom line: Social Security calculations follow a documented path from indexed earnings to AIME to PIA. Verify the inputs and current rules before making a claiming decision.
