Social Security Questions? Ask a Social Security Expert
Hi from Just Answer. I'm PDtax, and can assist.
SSDI benefits are typically larger payouts, but much more difficult to earn. SSDI is paid as if you retired, and you drew a full social security benefit. SSI is low income support, and is $733 or so for a single person in 2015.
Most social security payouts at full retirement age are nearly twice the $733 SSI benefit, so you would be doing much better drawing a disability pension.
Thanks for asking at Just Answer. Positive feedback is appreciated. I'm PDtax.
