How are SSDI benefits calculated?

Monthly Social Security Disability Insurance (SSDI) payment amounts are calculated based on your salary before you become disabled and the number of years you worked while paying Social Security taxes.

If you’re wondering how much your SSDI payment would be if a long-term injury or illness prevented you from working, the best place to start is your annual Social Security statement:

  • Go to the “Your Estimated Benefits” section.
  • Look for the rows labeled “Disability,” “Family,” and “Survivors.”
  • The information in the third column is the amount you were eligible for at the time your statement was prepared.
  • If you need a copy of your Social Security statement or need help obtaining one, call (877)261‑1947 for assistance.
