SSDI is a federal program that pays monthly cash to people who cannot work because of a disability

SSDI stands for Social Security Disability Insurance. It is a program run by the Social Security Administration that sends you money each month if you have a medical condition that prevents you from working, and if you have paid into Social Security through payroll taxes.

The key word is "insurance." You earned SSDI by working and paying Social Security taxes — it is not a welfare program. The money comes from the same fund that pays retirement benefits. When you worked, a portion of your paycheck went into this fund. If you become disabled before retirement age, SSDI lets you draw from it.

SSDI is different from other disability programs. SSI (Supplemental Security Income) is a needs-based program for people with low income and few resources, regardless of work history. Workers' Compensation covers injuries that happened on the job. Veterans' benefits are for military service-related disabilities. SSDI is specifically for people who worked, paid in, and now cannot work because of disability.

Key Takeaways

  • SSDI pays a monthly benefit to people who have a disability that prevents work and who have paid Social Security taxes through prior employment.
  • You must have a medical condition that is expected to last at least 12 months or result in death, and you must meet Social Security's definition of disability.
  • The amount you receive depends on your prior earnings record, not on how severe your condition is or how much money you have.
  • Family members — including a spouse, ex-spouse, or children — may also receive benefits based on your work record.
  • SSDI is administered by the Social Security Administration, and the process to receive it typically takes several months.

How much money you get each month

Your monthly SSDI payment is based on your Primary Insurance Amount, or PIA. This is calculated from your average earnings over your working years — specifically, your 35 highest-earning years. The Social Security Administration uses a formula that replaces a percentage of your past income.

The exact dollar amount varies widely. Someone who worked part-time or had lower wages will receive less than someone who worked full-time at higher wages. As of 2024, the average SSDI payment is around $1,550 per month, but this is just an average. Your actual payment could be significantly higher or lower.

Your payment does not change based on how disabled you are or how much money you have in savings. A person with a severe condition receives the same amount as a person with a less severe condition, as long as both meet the disability definition and have the same earnings history.

Who can receive SSDI

To receive SSDI, you must meet three requirements. First, you must have a medical condition that is expected to last at least 12 months or result in death. This includes physical conditions like cancer, heart disease, or spinal cord injury, and mental health conditions like schizophrenia or severe depression. The condition must be documented by medical evidence — test results, imaging, treatment records, or statements from your doctors.

Second, your condition must prevent you from doing substantial gainful activity. This is Social Security's term for work that earns a certain amount of money. In 2024, substantial gainful activity is generally defined as earning $1,550 per month or more (the amount changes each year). If you earn less than this, you may still be considered disabled. If you earn more, you are generally not.

Third, you must have work credits — proof that you paid Social Security taxes. The number of credits you need depends on your age when you become disabled. If you are under 24, you may need as few as 6 credits. If you are 31 or older, you typically need 40 credits, with at least 20 earned in the 10 years before you became disabled. You earn one credit for each $1,730 of wages in 2024 (this amount changes yearly).

Family members who can receive benefits on your record

When you receive SSDI, other people may also receive monthly payments based on your work record. These are called auxiliary beneficiaries. They do not need to have a disability themselves.

Your spouse can receive benefits at any age if they are caring for your child who is under 16. Your ex-spouse can receive benefits if you were married for at least 10 years, you are at least 62 years old, and you have been divorced for at least 2 years. Your unmarried children can receive benefits until age 19 if they are in high school full-time, or until age 18 if they are not in school. Children who became disabled before age 22 can receive benefits for life.

Each family member receives a separate payment, but there is a family maximum — a cap on the total amount that can be paid to your entire family. This maximum is usually between 150 and 180 percent of your Primary Insurance Amount. If family benefits would exceed this maximum, each family member's payment is reduced proportionally.

The medical evidence Social Security needs

Social Security does not take your word that you are disabled. You must provide medical evidence — documentation from doctors, hospitals, clinics, or mental health providers who have examined or treated you.

This evidence should include the results of tests, imaging, or lab work; notes from your doctors describing your symptoms and how they limit you; records of any hospitalizations or emergency room visits; and a list of medications you take and their side effects. If you see a therapist or psychiatrist, include those treatment records as well.

You do not need to pay for these records yourself. Social Security can request them directly from your providers, though this takes time. If you already have copies, sending them with your initial request speeds up the process. If you have not seen a doctor recently, Social Security may ask you to see one for a consultative examination — a one-time appointment that Social Security arranges and pays for.

How long the process takes

From the time you submit your request to the time you receive a decision typically takes 3 to 6 months. During this time, Social Security reviews your medical evidence, contacts your doctors, and determines whether you meet the disability definition.

If Social Security denies your request, you have the right to appeal. An appeal can take another 6 to 18 months, depending on the stage. At the first appeal level (reconsideration), a different Social Security employee reviews your case. If that is denied, you can request a hearing before an administrative law judge. This hearing stage is where most people who eventually win their case succeed.

While you wait for a decision, you do not receive any payments. This is why many people continue working part-time or rely on other income sources during the process. Once you are approved, your benefits can be backdated to the date you became disabled, so you may receive a lump sum for the months you waited.

What happens after you start receiving SSDI

Once approved, you receive a monthly payment by direct deposit. Social Security sends you a benefit verification letter that you can use to prove your income to landlords, lenders, or other organizations.

You must report changes to Social Security — if you start working, if your medical condition improves, if you move, or if your contact information changes. Failing to report changes can result in overpayments that you will have to repay.

If you work while receiving SSDI, there are rules about how much you can earn. During a trial work period, you can earn any amount without losing benefits. After the trial work period ends, you can earn up to a certain amount (called the substantial gainful activity level) and still receive reduced benefits. If you earn more than that, your benefits stop, but you may be able to restart them if your earnings drop again.

Frequently Asked Questions

Can I receive SSDI if I have never worked?

No. SSDI requires work credits earned through payroll taxes. If you have never worked or worked very little, you may be able to receive SSI (Supplemental Security Income) instead, which is a needs-based program. SSI has no work requirement but has strict limits on income and resources.

Does SSDI end when I turn 65?

No. When you reach full retirement age (between 66 and 67, depending on your birth year), your SSDI automatically converts to retirement benefits. The payment amount stays the same, but the program name changes. You continue receiving the same monthly amount for the rest of your life.

What if my condition gets better — do I lose my benefits?

If your condition improves enough that you can work at the substantial gainful activity level, your benefits will stop. Social Security conducts periodic reviews to check whether you still meet the disability definition. If your condition improves, you should report it. You may be able to use a trial work period to test whether you can work without when ready losing all benefits.

Can I work part-time and still receive SSDI?

Yes, during a trial work period you can earn any amount and keep your full benefit. After the trial work period, you can earn up to the substantial gainful activity amount (currently $1,550 per month) and receive reduced benefits. Earnings above that amount will reduce or eliminate your benefits.

How do I know if I have enough work credits?

You can create a "my Social Security" account at ssa.gov and view your earnings record and work credits. You can also call Social Security at 1-800-772-1213 and ask. Knowing your credit count before you explore helps you understand whether you meet the work requirement.
