What SSDI and SSI actually pay, how the SSA calculates your benefit, and why two people with the same condition receive different checks.
How much does disability pay under SSDI? Your earnings record decides
Your SSDI amount is calculated from your lifetime average earnings covered by Social Security — the same record that determines retirement benefits. The severity of your condition does not change the amount. You can see your own estimate by opening a my Social Security account.
SSI: a federal standard rate
SSI pays up to the federal benefit rate — $994 per month for an individual in 2026 — reduced by countable income. The current rates are published on the SSA’s SSI pages.

Because decisions take months or years, approval usually includes past-due benefits. SSDI can also pay up to 12 months of retroactive benefits before your application date if you were disabled then. Back pay is where the attorney fee comes from — never your monthly check.
Cost-of-living adjustments
Benefits rise with the annual COLA the SSA announces each fall, which also adjusts related thresholds like the SGA earnings limit.
Medicare and Medicaid ride along
After 24 months of SSDI entitlement you qualify for Medicare regardless of age; SSI recipients generally qualify for Medicaid in Tennessee. For many clients the health coverage is worth more than the check.
