SSDI is a federal insurance program, not a welfare program

SSDI stands for Social Security Disability Insurance. It is a program run by the Social Security Administration that pays monthly cash benefits to people who have worked and paid Social Security taxes, but can no longer work because of a medical condition expected to last at least 12 months or result in death.

The key word is "insurance." You or someone on your behalf paid into this program through payroll taxes while working. SSDI is not means-tested, which means your income or savings do not disqualify you. What matters is your work history and your medical condition.

SSDI is separate from Supplemental Security Income (SSI), which is a needs-based program for people with low income and few resources. The two programs have different rules, different payment amounts, and different work incentives. This guide focuses on SSDI.

Key Takeaways

  • SSDI pays monthly benefits to people who have worked, paid Social Security taxes, and now cannot work due to a medical condition lasting at least 12 months.
  • You must have earned enough work credits — typically 40 total, with at least 20 earned in the 10 years before you became disabled — to receive SSDI.
  • The Social Security Administration decides whether your condition meets their definition of disability, which is stricter than most people's everyday use of the word.
  • SSDI benefits are based on your own earnings record, not on how much money you need or how severe your condition feels to you.
  • Family members may also receive benefits based on your work record if you are approved, even if they have never worked.

How work credits determine whether you can receive SSDI

To receive SSDI, you must have earned enough work credits by paying Social Security taxes. You earn one work credit for every $1,550 of wages or self-employment income you report (this dollar amount changes each year). You can earn a maximum of four work credits per year.

Most people need 40 work credits total to receive SSDI. However, if you became disabled before age 24, you may need fewer credits. If you became disabled between ages 24 and 31, you generally need credits for half the years between age 21 and the year you became disabled.

You also must have earned at least 20 of your 40 credits in the 10 years when ready before you became disabled. This is called the "recency requirement." It exists because SSDI is meant to replace income from recent work, not to pay benefits based on a job you held 20 years ago.

You can check your work credit record by creating an account on ssa.gov and viewing your Social Security Statement. This statement shows how many credits you have earned and in which years.

What "disability" means under SSDI rules

The Social Security Administration has a specific definition of disability that is narrower than how most people use the word. You must have a medical condition that prevents you from doing any substantial work, and that condition must be expected to last at least 12 months or result in death.

"Substantial work" means earning more than a certain monthly amount. In 2024, that amount is $1,550 per month (this changes yearly). If you are earning more than this amount, Social Security will not consider you disabled, regardless of your medical condition.

Social Security does not award SSDI based on how much pain you are in, how much your condition limits you in daily life, or how much you want to stop working. They award it based on whether your condition prevents you from doing any work that exists in the national economy, taking into account your age, education, and work experience.

This is why many people are denied SSDI on their first process, even when they have a serious medical condition. The program's definition of disability is a legal one, not a medical one.

How SSDI benefit amounts are calculated

Your SSDI benefit amount is based on your own earnings record — specifically, on your average earnings over your working years. Social Security calculates this by looking at your highest 35 years of earnings, adjusting them for inflation, and then explore a formula to arrive at your Primary Insurance Amount (PIA).

The formula is designed so that people who earned less during their working years receive a higher percentage of their average earnings as a benefit. Someone who earned $20,000 per year will receive a higher percentage of that income than someone who earned $100,000 per year. However, the person who earned more will still receive a higher dollar amount.

In 2024, the average SSDI benefit is around $1,550 per month, but this varies widely. Your actual benefit depends entirely on what you earned. You can see an estimate of your future SSDI benefit on your Social Security Statement at ssa.gov.

Family members who can receive benefits on your record

When you are approved for SSDI, certain family members may also receive benefits based on your work record. These family members do not need to have worked themselves. They receive what is called a "family benefit."

Your spouse can receive a benefit if they are age 62 or older, or if they are caring for your child who is under age 16. Your ex-spouse can receive a benefit under the same rules if your marriage lasted at least 10 years. Your children can receive a benefit if they are under age 18, or under age 19 if they are still in high school, or any age if they became disabled before age 22.

There is a family maximum benefit — the total amount that can be paid to you and all family members combined. This maximum is usually 150 to 180 percent of your Primary Insurance Amount. If family benefits would exceed this maximum, each family member's benefit is reduced proportionally.

How SSDI differs from SSI and workers' compensation

SSDI and SSI are often confused because both are run by Social Security and both pay benefits to people with disabilities. The main difference is that SSDI is based on your work history and is not means-tested, while SSI is based on financial need and has strict income and resource limits.

Workers' compensation is a different program entirely. It covers injuries or illnesses that happen at work or because of work. SSDI covers any medical condition that prevents you from working, whether or not it is work-related. You can receive both SSDI and workers' compensation, though your SSDI benefit may be reduced if you also receive workers' compensation.

Some people receive both SSDI and SSI. This happens when someone has a work history but their SSDI benefit is very low — so low that they also meet the income limits for SSI. The two benefits are coordinated so you do not receive more than the SSI maximum.

What happens to SSDI when you reach full retirement age

When you reach your full retirement age (which depends on your birth year and ranges from 66 to 67), your SSDI benefit automatically converts to a retirement benefit. The amount does not change — you receive the same monthly payment. The only difference is the name of the program and the rules that explore to how much you can earn while receiving benefits.

At full retirement age, you can earn any amount and still receive your full benefit. Before full retirement age, your benefit is reduced if you earn more than $23,400 per year (this amount changes yearly). This is why some people choose to wait until full retirement age to claim, even if they became disabled earlier.

Family members' benefits also convert to retirement or survivor benefits at the appropriate time, but the amounts remain the same.

Frequently Asked Questions

Can I receive SSDI if I have never worked?

No. SSDI requires a work history and work credits. If you have never worked or have very few work credits, you may be able to receive SSI instead, which is a needs-based program. SSI has no work history requirement, but it has strict income and resource limits.

Does SSDI cover mental health conditions?

Yes. Mental health conditions including depression, anxiety, bipolar disorder, and schizophrenia can may have access to for SSDI if they prevent you from doing any substantial work. Social Security evaluates mental health conditions the same way it evaluates physical conditions — based on whether they prevent you from working, not based on diagnosis alone.

What is the difference between SSDI and disability insurance through my employer?

Employer disability insurance (sometimes called long-term disability or LTD) is a private insurance benefit offered by some employers. SSDI is a federal program. They have different definitions of disability, different benefit amounts, and different rules. You can receive both if you have employer coverage and also meet SSDI's requirements.

How much does SSDI cost, and who pays for it?

SSDI is funded through payroll taxes. Your employer and you each pay 6.2 percent of your wages into the Social Security trust fund. Self-employed people pay 12.4 percent. There is no separate process fee or cost to explore for SSDI.

Can I work while receiving SSDI?

SSDI has work incentives that allow you to test your ability to work without when ready losing your benefits. You can earn up to $1,550 per month (in 2024) without affecting your benefit. Above that amount, your benefit is reduced. After nine months of work above the substantial earnings level, your case is reviewed to determine if you are still disabled.
