It depends on which program and what you consider a lot. There are three main disibility programs: SSI, SSDI as the dependant of a retired worker, and SSDI as a disabled worker. Everyone is eligible for SSI but pays the least (maximum $733 / month federal, some states add a small amount). Someone on SSI whose parent has enough qualifying working quarters can switch to SSDI at 1/2 of the benefit the retiree would be eligible for at full retirement age. This currently tops out at around $1400 / month. Finally, if you yourself have worked enough qualifying quarters (6-20 depending on age) and become disabled you may be eligible for primary SSDI. These top out at around $2600 / month, but average much less. An additional benefit of SSDI, is that after two years a recipient becomes eligible for Medicare.
