Return to Videos The amount of money that you get for your SSDI is determined by the amount of money you paid into the system. If you've been working on the books and paying into the system regularly, you'll get a decent SSDI payment. There’s no telling how much they are. The average is usually between $890 and $1,100 a month. If you've paid in more, if you've been a good earner or a higher earner, it's going to be higher than that. Could be as high as $2,600 a month. It all depends on how much you pay in.
