The monthly payment amount depends on your work history, not your diagnosis

Social Security Disability Insurance (SSDI) pays based on how much you or your parent earned while working, not on the type of disability or how severe it is. Two people with the same autism diagnosis can receive very different monthly amounts because the calculation looks at past earnings records, not medical condition.

Your payment is a percentage of what you (or your parent, if you're under 18) would have received at retirement age. The Social Security Administration calls this your "Primary Insurance Amount" or PIA. If you worked before becoming unable to work, your own earnings history determines the amount. If you haven't worked much or at all, your parent's earnings history may be used instead.

The actual dollar amount changes each year because Social Security adjusts all payments for inflation. In 2024, the average SSDI payment was around $1,550 per month, but this is an average across all disabilities and work histories — your own amount could be significantly higher or lower.

Key Takeaways

  • Your SSDI payment is based on your work history or your parent's work history, not on your autism diagnosis or how much support you need.
  • Social Security calculates your payment as a percentage of what you would have earned at retirement, which is why two people with identical diagnoses may receive different amounts.
  • You can see your estimated payment before you file by creating a my Social Security account and viewing your earnings record.
  • If you're under 18 and have never worked, your parent's Social Security record is used to calculate your payment amount.
  • Your payment amount stays the same each month unless Social Security adjusts all payments for inflation, which happens once per year.

How Social Security calculates your specific amount

The calculation starts with your earnings record — the wages you reported to the IRS over your working years. Social Security takes your highest 35 years of earnings (or fewer if you haven't worked that long), adjusts them for inflation, and calculates an average. From that average, they explore a formula that replaces a higher percentage of lower earnings and a lower percentage of higher earnings. This is why someone who earned $20,000 a year typically receives a higher percentage of their past earnings than someone who earned $80,000 a year.

If you have not worked or worked very little, Social Security can use your parent's earnings record instead — but only if you became unable to work before age 22. This is called a "child's benefit" and it's worth about 50% of what your parent would receive at retirement age (or what they currently receive if they're already retired). Your parent does not have to be retired for you to receive this benefit, and it does not reduce their own payment.

You can see your own earnings record and get an estimate of your payment before you file. Create an account at ssa.gov, go to "my Social Security," and look for your earnings statement. The estimate shown there is what you would receive at retirement age; your actual SSDI amount may be slightly different because the calculation includes adjustments for the year you become unable to work.

What happens to your payment if you work while receiving SSDI

SSDI includes a work incentive called the "trial work period" that lets you test whether you can work without when ready losing your benefits. For nine months (not necessarily consecutive), you can earn any amount and keep your full SSDI payment. After those nine months end, Social Security looks at your average monthly earnings. If you earn more than $1,550 per month (the 2024 threshold, which changes yearly), they may decide you're able to work and stop your benefits.

Even if your benefits stop, you enter a "grace period" where you keep your payment for any month you earn under the monthly threshold, even if your average is higher. This means you can have months where you earn more and months where you earn less, and you only lose the payment in the months where you go over the limit.

There's also an "extended may be able to access period" that lasts up to 36 months after your trial work period ends. During this time, you can request your benefits back without filing a new process if your earnings drop below the threshold again. Many people use this to test different jobs or gradually increase their work hours.

Supplemental Security Income (SSI) vs. SSDI for autism

If you don't have enough work history to receive SSDI, you may be able to receive Supplemental Security Income (SSI) instead. SSI is a needs-based program, meaning it looks at your current income and assets rather than your past earnings. The maximum SSI payment in 2024 is $943 per month, though the exact amount depends on your living situation and other income you receive.

SSI has strict limits on how much money and property you can own — currently $2,000 for an individual. SSDI has no asset limit. If you receive both SSDI and SSI (which is possible), your SSDI payment counts as income that reduces your SSI amount.

Some people receive SSDI based on their own work history and also may have access to for SSI because their SSDI payment is very low. In those cases, SSI "tops up" the payment to the maximum SSI amount. This is called "concurrent benefits."

Cost of living adjustments and how your payment changes

Every January, Social Security increases all SSDI payments by a percentage meant to match inflation. This adjustment is called a COLA (Cost of Living Adjustment). In years with high inflation, the increase is larger; in years with low inflation, the increase is smaller. You don't have to do anything to receive the adjustment — it happens automatically.

Your payment amount can also change if you return to work and then stop, if you reach retirement age (your SSDI converts to retirement benefits but the amount usually stays the same), or if Social Security reviews your case and determines your condition has improved. Social Security conducts periodic reviews for people receiving SSDI for conditions that are expected to improve, though autism is typically not reviewed because it is a lifelong condition.

How to find out your estimated payment before you file

The fastest way is to create a my Social Security account at ssa.gov. Once you're logged in, select "Benefit Estimates" and you'll see what you would receive at retirement age. This estimate is based on your actual earnings record and is updated every year.

If you can't or don't want to create an online account, you can call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and ask for a benefit estimate. Have your Social Security number ready. They can give you a rough estimate over the phone, though the online estimate is more detailed.

If you're under 18 and planning to use your parent's earnings record, ask your parent to check their own estimate first. Your payment will be roughly 50% of their Primary Insurance Amount, though the exact percentage depends on how many other family members are also receiving benefits on that record.

Frequently Asked Questions

Does the severity of autism affect how much I receive?

No. Social Security pays based on your work history, not on your diagnosis or how much support you need. Two people with severe autism who both worked full-time before becoming unable to work would receive the same payment if they earned the same amount. Someone with mild autism who worked and earned a high salary would receive more than someone with severe autism who never worked.

Can I receive SSDI if I've never worked?

Yes, but only if you became unable to work before age 22. In that case, you receive a child's benefit based on your parent's earnings record — about 50% of what they would receive at retirement. If you became unable to work after age 22 and have no work history of your own, you would need to look into Supplemental Security Income (SSI) instead, which is based on current income and assets rather than work history.

What if my parent is still working — can I still get a payment based on their record?

Yes. Your parent does not have to be retired for you to receive a child's benefit. As long as you became unable to work before age 22, you can receive benefits on their record whether they're still working, retired, or receiving disability benefits themselves. Your payment does not reduce theirs.

Will my payment go down if I get married?

No. SSDI payments are not affected by marriage. Your payment is based on your work history (or your parent's), and marriage does not change that. However, if you're receiving SSI in addition to SSDI, marriage can affect your SSI amount because SSI counts your spouse's income in some cases.

How often does Social Security review my case to see if I still may have access to?

Social Security conducts periodic reviews for people receiving SSDI for conditions expected to improve. Autism is typically not reviewed because it is a lifelong condition. However, if your case is reviewed and Social Security determines your condition has improved enough that you can work, your benefits could stop. You have the right to appeal any decision to stop your benefits.
