5. Scenario Complexity — Choose from: Basic / Standard, Typical, Advanced / Complex

Based on your inputs, the calculator provides:

• Estimated Monthly Benefit — Dollar amount based on current market rates

• SSA disability determination statistics (approval rates by age, condition, and stage of appeal)
• SSA annual statistical supplement for average SSDI benefit amounts by age and gender

Key Assumptions:

• SSDI benefits are based on your earnings record — higher lifetime earnings result in higher benefits (max approximately $3,822/month in 2026)

Several factors influence your ssdi benefits estimator estimate:

Average Indexed Monthly Earnings ($)

A key variable in determining your ssdi benefits estimator estimate.

Years Worked

A key variable in determining your ssdi benefits estimator estimate.

How long ago did disability begin?

Ranges from "About 6 months ago" to "2+ years ago." Choosing 2+ years ago can cost 4.0x more than About 6 months ago.

Current Age

A key variable in determining your ssdi benefits estimator estimate.

Scenario Complexity

Ranges from "Basic / Standard" to "Advanced / Complex." Choosing Advanced / Complex can cost 1.5x more than Basic / Standard.

Jurisdiction

Settlement values and damage caps vary by state and county. Some jurisdictions impose caps on non-economic damages that significantly affect outcomes.

Case Complexity

Disputed liability, multiple parties, or severe injuries increase both potential settlement value and timeline. Attorney representation significantly affects recovery amounts.

After you run the calculator, your results include interactive sections that help you make informed decisions:

Damages Breakdown

Review each component of your estimated settlement or award separately — medical expenses, lost wages, and non-economic damages each appear as their own line item. This transparency helps you understand how each factor contributes to the total estimate and gives you realistic expectations for settlement discussions.

Visual Chart

The chart provides a visual summary of your results, making it straightforward to compare components at a glance. This is helpful when sharing estimates with a spouse, business partner, or advisor — the visual format communicates the key story faster than numbers alone.
