Many people assume that Social Security disability benefits are based on how severe their medical condition is, but the amount you receive is actually determined by your work and earnings history.
Social Security Disability Insurance (SSDI) benefits are based on your lifetime earnings that were subject to Social Security taxes. The Social Security Administration (SSA) reviews your work history and calculates your average earnings over time, adjusting for inflation. This figure is used to determine your Average Indexed Monthly Earnings (AIME), which forms the foundation of your benefit amount.
Once your AIME is calculated, the SSA applies a formula to determine your Primary Insurance Amount (PIA). The PIA is the base monthly benefit you would receive if your disability claim is approved.
It is important to understand that SSDI benefits are not based on household income or financial need. Instead, they reflect what you have paid into the system through payroll taxes over your working years.
Additional factors can affect the amount you actually receive. For example, certain public disability benefits or workers’ compensation payments may reduce your monthly SSDI amount. Cost of living adjustments may also increase your benefits over time.
And of course, this only applies to SSDI benefits. Supplemental Security Income (SSI) benefits are capped at $994 for individuals in 2026.
Because SSI is a need-based program and payments are not based on work history, there are quite a few additional rules for the program, and these benefits are often substantially less than the monthly maximum.
