The core SSDI benefit is a monthly cash payment. The amount is based on your average lifetime earnings covered by Social Security, not on how severe your disability is or on your other income or assets. The estimated average monthly SSDI payment for a disabled worker in 2026 is $1,630, according to the SSA’s 2026 cost-of-living adjustment fact sheet. You can see your own estimate by creating a my Social Security account at ssa.gov. Payments generally continue as long as you remain disabled, and at full retirement age they convert to retirement benefits in the same amount.
SSDI can also include back pay for the time your claim was pending. The program has a five-month waiting period, and benefits are generally paid starting with the sixth full month of disability. If SSA approves a claim after you have been waiting, you may receive back pay for eligible months, including up to 12 months before your application date.
You generally become eligible for Medicare after receiving SSDI for 24 months, no matter your age. SSA also adjusts SSDI benefits each year for the cost of living, and the increase for 2026 was 2.8%.
Some family members, such as a spouse, minor children, or an adult child disabled before age 22, may qualify for payments based on your record. Total family payments are subject to a family maximum.
