A disability benefit calculator estimates monthly Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) payments. SSDI is based on your work history and average earnings, while SSI is a needs-based program with a flat maximum amount.
Formule
SSDI Benefit = PIA (Primary Insurance Amount) based on AIME (Average Indexed Monthly Earnings)
- AIME
- Average Indexed Monthly Earnings ($/month) — Average of highest 35 years of earnings, indexed for inflation
- PIA
- Primary Insurance Amount ($/month) — Monthly benefit amount calculated from AIME using bend points
- FBR
- Federal Benefit Rate ($/month) — Maximum SSI payment ($943 in 2024)

- 2Apply the PIA formula with bend points to get the monthly benefit
- 3For SSI: Start with the federal benefit rate ($943/month in 2024) and subtract countable income
- 4Consider state supplements that may increase the SSI payment

Questions fréquentes
Can I receive both SSDI and SSI?
Yes, this is called concurrent benefits. If your SSDI amount is low, SSI can supplement it up to the SSI maximum, and you may qualify for Medicaid.
How long does disability approval take?
Initial decisions take 3–6 months. If denied, reconsideration takes another 3–6 months. A hearing before an ALJ can take 12–18 months. Many claims are approved at the hearing level.
