SS Disability Benefits Calculator
Estimate your potential monthly Social Security disability benefits.
Estimated Monthly Benefit:
$0.00
This is an estimate. Actual benefits may vary. Consult with the Social Security Administration for official figures.
Understanding Social Security Disability Benefits
Social Security disability benefits are designed to provide financial assistance to individuals who are unable to work due to a medical condition that is expected to last at least one year or result in death. There are two main programs that provide these benefits:
- Social Security Disability Insurance (SSDI): For individuals who have worked and paid Social Security taxes for a sufficient amount of time.
- Supplemental Security Income (SSI): A needs-based program for individuals with limited income and resources, regardless of their work history.
This calculator provides an *estimate* of potential SSDI benefits. The actual amount you receive depends on your lifetime earnings history, the Social Security Administration's calculation of your Primary Insurance Amount (PIA), and other factors.
How is the Primary Insurance Amount (PIA) Calculated?
Your PIA is the amount you would receive if you were eligible for retirement benefits at your full retirement age. For disability benefits, the calculation is similar but considers your disability onset date. The SSA uses your 35 highest-earning years to calculate your Average Indexed Monthly Earnings (AIME). This AIME is then applied to a formula that results in your PIA.
The formula for PIA involves three "bend points" that change each year. For example, for individuals who turned 62 in 2023, the formula looked something like this:
- 90% of the first $1,115 of AIME
- 32% of AIME between $1,115 and $6,721
- 15% of AIME over $6,721
This calculator uses a simplified approximation to provide an estimate. It takes your reported average monthly earnings and years worked to derive a proxy for your AIME and then applies a generalized bend-point structure.
Factors Affecting Your Benefit Amount
- Your Earnings Record: Higher lifetime earnings generally lead to higher benefits, up to a certain limit.
- Age of Disability Onset: The earlier you become disabled, the more years your benefit might be paid out, but the calculation itself is based on your earnings history.
- Number of Years Worked: A sufficient number of years contributing to Social Security is required for SSDI eligibility.
- Other Income/Benefits: Some other benefits you may receive could affect your SSI eligibility or, in some cases, your SSDI amount (e.g., workers' compensation offset).
- Family Benefits: If you are eligible for disability benefits, certain family members may also be eligible for benefits on your record.
Using This Calculator
To get an estimate, input your average monthly earnings from your most recent full year of work, the number of years you have contributed to Social Security through payroll taxes, your birth year, and the year your disability began or is expected to begin.
Important Note: This calculator is for educational and estimation purposes only. It is not a substitute for professional advice or an official determination from the Social Security Administration (SSA). Eligibility criteria and benefit calculations can be complex. For accurate information, please contact the SSA directly or consult with a qualified legal professional specializing in Social Security law.

// Adjust for years worked. A minimum of 20 years is generally needed for SSDI,
// but this calculation is a simplified estimate.
// A very rough adjustment: if fewer than 20 years, a reduction might apply,
// or if much more, it might not increase benefit beyond a certain point for SSDI.
// For simplicity, we'll use the calculated PIA directly but acknowledge this is a simplification.
var estimatedBenefit = pia;
// Apply a very rough adjustment based on years worked to reflect contribution period.
// This is highly simplified. Actual calculations are more complex.
var yearsToFullRetirement = 67 – (birthYear + (disabilityYear – birthYear)); // Rough estimate
var effectiveYearsWorked = Math.min(yearsWorked, 35); // Cap at 35 highest earning years proxy
// Further very rough adjustment – this is highly speculative and for illustration only.
// The actual PIA calculation doesn't directly scale with years worked like this.
// This is an attempt to reflect that longer contributions generally mean a stronger record.
var adjustmentFactor = Math.min(effectiveYearsWorked / 20, 1.2); // Capped at 20% increase, very rough heuristic
estimatedBenefit = estimatedBenefit * adjustmentFactor;
// Ensure benefits don't exceed maximum possible (this limit changes yearly)
