Servicemembers past and present are used to decrypting all manner of acronyms, but when it comes to Social Security benefits, some may find themselves out of their element.

That includes two programs which may provide additional income for the disabled or for those age 65 and older (or both): SSDI and SSI.

The Basics: SSDI

What: Social Security Disability Insurance

Who: Available to those who meet the Social Security Administration’s definition of “disabled” (check your status via this questionnaire) and have made qualifying contributions to the Social Security trust fund through earnings contributions via the Federal Insurance Contributions Act (FICA). Age is not a factor.

When: Benefits being in the sixth full month of disability.

How Much: Amount varies by work history. Average 2023 monthly benefit was $1,352.32.

The Basics: SSI

What: Supplemental Security Income

Who: As with SSDI, those deemed disabled can qualify for this program. It’s also open to those age 65 and over, regardless of disability. However, eligible applicants have limited or no income or resources.

When: Benefits begin the first full month after the date of the claim. SSI recipients also become immediately eligible for Medicare in most states.

How Much: Amount varies by income. Average 2023 monthly benefit was $676.60.
