What is SSI?

SSI (Supplemental Security Income) is a needs-based program for people with limited income and resources who are 65+, blind, or disabled. SSI payments are funded by general tax revenue, not Social Security taxes.

Use our SSI payment calculator to estimate your monthly benefit.

What is SSDI?

SSDI (Social Security Disability Insurance) is an earned benefit for workers who become disabled. You must have paid Social Security taxes for enough quarters to qualify. SSDI benefits are based on your earnings history, not financial need.

Can You Get Both SSI and SSDI?

Yes! Some people receive both SSI payments and SSDI benefits simultaneously. This is called "concurrent benefits." If your SSDI payment is low and you have limited resources, you may qualify for SSI to supplement your income.

Our SSI payment calculator can help you estimate additional SSI benefits even if you receive SSDI.
