# How much will my SSDI check be? Last updated Jul 19, 2026 Reviewed by Jason Burns, Editorial Steward — https://ssdidirectanswers.com/steward Published by SSDI Direct Answers · Licensed under Citation License 1.0 — https://ssdidirectanswers.com/license Your SSDI amount is based on your own lifetime average earnings in Social Security-covered work — SSA indexes your earnings history to compute your Average Indexed Monthly Earnings (AIME) and applies a weighted formula to get your Primary Insurance Amount (PIA) — not on how severe your disability is or on household need. ## What the government has said, on the record > "However, benefits are based on average earnings in employment covered by Social Security over a working lifetime (35 years for retired workers). In determining average earnings for Social Security benefit purposes, years with no covered earnings are counted as years of zero earnings, as if the person had not worked at all in these years." — **David A. Rust**, Deputy Commissioner for Retirement and Disability Policy, Social Security Administration, [Statement, hearing before the House Committee on Ways and Means, Subcommittee on Social Security](https://www.ssa.gov/legislation/testimony_011608.html), January 16, 2008. *Editor's note: The parenthetical (35 years for retired workers) reflects the retirement computation; disability computations use fewer years depending on age at onset. The ~$1,580 average benefit figure in the answer is an approximate early-2025 figure and changes annually with the COLA.* Your SSDI amount is based on your own lifetime average earnings in Social Security-covered work — SSA indexes your earnings history to compute your Average Indexed Monthly Earnings (AIME) and applies a weighted formula to get your Primary Insurance Amount (PIA) — not on how severe your disability is or on household need. For context, the average monthly benefit for a disabled worker was roughly $1,580 in early 2025 (historical/approximate figure that rises each year). Benefit checks change annually with the cost-of-living adjustment, and the AIME/PIA formula bend points are updated for each new cohort every year.
