Step 1 of 2What Are AIME and PIA?

PIA (Primary Insurance Amount) is your resulting base monthly SSDI check calculated using statutory bend-point tiers.

Other Factors That Affect Your SSDI Payment
While your Primary Insurance Amount (PIA) establishes your baseline monthly check, your actual take-home payment can be adjusted by several factors:
No Age Early Filing Reduction
Unlike Social Security retirement benefits, SSDI payments are never reduced for early age. You receive 100% of your PIA regardless of your age when you become disabled.
Auxiliary Family Add-ons (+50%)
Eligible minor children and qualifying spouses can receive up to 50% of your PIA, subject to the statutory SSDI Family Maximum cap.
Workers' Compensation Offset
Combined public disability or workers' compensation payments cannot exceed 80% of your pre-disability average current earnings. Excess is offset.
Government Pension Offset (GPO/WEP)
Work in non-covered state/local government jobs where Social Security taxes were not withheld may reduce benefits under WEP/GPO rules.
