Social Security disability/retirement question...

[pipi_k]

Let's say someone became disabled before the age of 50 and worked long enough to be able to qualify for SSDI.

So the person would like to turn that over into regular (early) retirement at the age of 62.

The chart listing that person's year of birth says that early retirement would reduce the person's monthly benefits by 25% if that person were still working.

My question is...if someone is getting SSDI but elects to turn disability over to early retirement at 62, does the disability benefit amount get reduced by 25%, stay the same, or would early retirement mean that whatever regular benefits he would have gotten based on work history would be reduced by 25%?

Has anyone here had any experience with that sort of thing?
