Social Security Disability Insurance (SSDI) benefit cases receive approval from the Social Security Administration (SSA) individually. The SSDI payment amount depends upon your average indexed monthly earnings prior to becoming disabled. There are adjustments for low wage earners and family maximum levels that may change from year-to-year. Your payment may also be lowered or “offset” based on whether you receive other types of disability benefits (i.e., Workers’ Compensation). The average monthly benefit amount in 2018 was $1,197.
