What income is used when ssa calculates benefits for individuals that are collecting worker’s compensation? I had a salary of $103,000 with locality it was $120,000 . The 3 years prior to my in the job injury I made 138,000, 143,000. & 144,000. My SS statement stated $2600 benefit per month. My actual award letter stated $947. Don’t get me wrong I am grateful for the benefit, however, I would like to run through the numbers myself. When I went through the numbers with worker’s compensation I received a sizable back payment as the computation was done incorrectly.
