SSDI Benefit Estimator for Adults
Use this calculator to get an estimated idea of your potential monthly Social Security Disability Insurance (SSDI) benefit. Your actual benefit amount will be determined by the Social Security Administration (SSA) based on your complete earnings record.
Understanding Social Security Disability Insurance (SSDI)
Social Security Disability Insurance (SSDI) is a federal insurance program that provides benefits to individuals who have worked and paid Social Security taxes, and who are now unable to work due to a severe medical condition. Unlike Supplemental Security Income (SSI), which is needs-based, SSDI benefits are based on your past earnings record.
Eligibility for SSDI
To qualify for SSDI, you must meet two main criteria:
- Work Credits: You must have accumulated a sufficient number of "work credits" through your employment. Work credits are earned by paying Social Security taxes on your earnings. The number of credits needed depends on your age when you become disabled. Generally, you need 20 credits (5 years of work) in the 10 years immediately before your disability began, but younger workers may need fewer.
- Definition of Disability: The Social Security Administration (SSA) has a strict definition of disability. You must have a medical condition that prevents you from engaging in any "substantial gainful activity" (SGA) and is expected to last for at least 12 months or result in death. The SSA does not consider partial disability or short-term disability.
How SSDI Benefits Are Calculated
Your monthly SSDI benefit amount is primarily based on your lifetime average earnings covered by Social Security. The SSA uses a complex formula to determine your Primary Insurance Amount (PIA), which is the basic benefit amount before any adjustments.
The key steps in calculating your PIA are:
- Average Indexed Monthly Earnings (AIME): Your earnings from past years are "indexed" to account for changes in general wage levels over time. The SSA then calculates your AIME by averaging your highest indexed earnings over a specific number of years (known as "computation years"). The number of computation years depends on your age at disability onset.
- Bend Points: The AIME is then run through a formula that uses "bend points." These are dollar amounts that divide your AIME into segments, with different percentages applied to each segment. For 2024, the bend points for PIA are:
- 90% of the first $1,174 of AIME
- 32% of AIME between $1,174 and $7,078
- 15% of AIME over $7,078
This calculator uses a simplified approach to estimate your AIME based on your average annual earnings and then applies the 2024 bend points to calculate your estimated PIA.
Family Maximum Benefit
While this calculator focuses on your individual benefit, it's important to know that if you have eligible family members (such as a spouse caring for your child, or unmarried children under 18 or disabled), they may also be able to receive benefits based on your work record. However, there is a "family maximum" amount that can be paid on one worker's record, typically between 150% and 188% of your PIA. If the sum of individual benefits exceeds this maximum, each person's benefit will be reduced proportionally.
Limitations of This Calculator
This calculator provides an estimate only. Your actual SSDI benefit may differ for several reasons:
- Simplified AIME: The calculator uses your provided "Average Annual Earnings" as a direct proxy for indexed earnings. The SSA's actual calculation involves indexing specific annual earnings over many years, which can be complex.
- Work Credits: While the calculator asks for years worked, it provides a general guideline for insured status. The SSA determines exact work credits based on your detailed earnings record.
- No Family Maximum: This calculator does not account for the family maximum benefit.
- Other Factors: Other factors like Workers' Compensation or other public disability benefits can affect your SSDI amount.
For a precise benefit estimate, you should create an account on the SSA's website (my Social Security) to view your official earnings record and benefit estimates, or contact the SSA directly.
Applying for SSDI
You can apply for SSDI benefits online, by phone, or in person at your local Social Security office. The application process can be lengthy and requires detailed medical and work information.
