SSDI Calculator

This calculator estimates your Social Security Disability Insurance (SSDI) backpay based on your application date, disability onset date, and monthly SSDI benefit amount. It gives a clear picture of how much you might receive in retroactive payments.

  • Disability Onset Date: The date SSA determines your disability began, usually noted in your approval letter or medical records.
  • Monthly SSDI Benefit Amount: The amount listed in your SSA award letter or available by logging into your account on the SSA website.
