A rating of 100% disability means the service-connected mental or physical impairment renders it impossible for the average person to remain substantially and gainfully employed.
This does not mean that someone who meets the qualifications for 100% VA disability cannot work at all. Veterans may still do odd jobs and very low pay work, which is referred to as marginal employment.
Nonetheless, a 100% disability rating entitles a veteran to the maximum monthly compensation available. As of December 1, 2021, the monthly benefit for a 100% rating is $3,332.06. The VA will provide a larger amount to disabled veterans with dependents.
