The maximum monthly payment for Social Security Disability Insurance (SSDI) for this year is $2,788, but few beneficiaries will actually receive this amount. The average monthly check will likely be lower. In 2017 the average SSDI check was $1,171.
For those who qualify for Supplemental Security Income (SSI) payments the maximum amounts for 2018 are $750 per month for an eligible individual and $1,125 for an eligible individual with an eligible spouse.
