Social Security generally defines substantial earnings as a certain dollar amount. In 2017, generally $1,170.00 earnings per month is substantial for non-blind workers and $1,930.00 is substantial work for the blind. These amounts refer to your gross earnings if you are an employee and your net profit if you are self-employed.
If you receive $1,100 per month in SSDI payments, you would only receive $1,300 per month from the FERS program due to the amount you are collecting from the SSA. This would still total $2,400 per month. You would just be getting a portion of that $2,400 from FERS and a portion from SSDI. After the first 12 months of your disability you will receive 40 percent of your 3-year-average high salary minus 60 percent of whatever you receive in SSDI benefits.
