In 2017, the average Social Security disability benefit (SSDI) was $1,171.00 per month. The maximum disability benefit a beneficiary can receive is $2,687. The amount you receive in disability benefits is based on how much you paid in Social Security taxes. If you have a favorable decision in your Supplemental Security Income case, your maximum benefit is approximately $735.00 per month. However, the Social Security Administration will likely deduct a certain percentage of your benefits if you are living in another person’s household or have assets of value.
