How much money you will receive if you qualify for disability benefits will depend on whether on whether or not your application was for SSI (Supplemental Security Income) or SSDI (Social Security Disability Insurance).
The full monthly federal benefit for an SSI recipient is fixed, subject to annual increases. In 2014, the federal base payment is $721. However, you will likely receive more or less than this amount if your state pays an extra state supplemental payment or you make any income. For more information, see our article on how much SSI pays.
In contrast, the monthly benefit for a Social Security disability recipient depends on prior earnings: how much and how long an employee worked and paid into the Social Security system. For more information, see our article on how much SSDI pays.
In neither case does the disability payment depend on how disabled you are (unlike other programs for injured or disabled persons, such as workers' compensation and veterans disability).
Back Payments of Benefits
Most disability applicants who are approved for benefits also receive some type of back payments or retroactive disability benefits. The amount of bckpay you'll get depends on whether you get SSDI or SSI and when you applied for disability. For more information, see our section on Social Security disability back payments.
