The payment amount depends on your work record, not your child's condition

Your child's SSDI payment is based on your lifetime earnings record, not on the severity of their disability. Social Security calculates what you would receive if you became disabled, and your child gets a percentage of that amount—typically 50 percent. The actual dollar amount varies widely because it depends entirely on how much you earned and for how long.

If you have not worked much, or took time out of the workforce, your child's payment will be smaller. If you worked steadily at higher wages, the payment will be larger. Social Security calls your calculated benefit amount your Primary Insurance Amount, or PIA. Your child receives half of your PIA, with some exceptions explained below.

You can see an estimate of your own benefit amount by creating an account at ssa.gov and viewing your Social Security Statement. That statement shows your estimated benefit if you became disabled today. Your child would receive roughly half that amount.

Key Takeaways

  • Your child's payment is calculated as a percentage of your work record, not their disability—usually 50 percent of your Primary Insurance Amount.
  • The actual dollar amount depends on your lifetime earnings, so you can estimate it by checking your Social Security Statement at ssa.gov.
  • A family maximum applies: all your children and spouse combined cannot receive more than 150 to 180 percent of your benefit amount, which may reduce each child's payment if multiple family members receive benefits.
  • The payment continues until your child turns 19 if they are in high school full-time, or age 18 if they are not in school, regardless of when their disability began.
  • Your child's own work history does not affect the amount they receive while under age 19 or 18, but working and earning above the limit can reduce or stop the payment.

How Social Security calculates your child's payment

Social Security uses a formula based on your average earnings over your working years. The formula is weighted to replace a higher percentage of lower earnings and a lower percentage of higher earnings. Once Social Security calculates your Primary Insurance Amount, your child receives a set percentage of it.

For a child whose parent is disabled or retired, the standard rate is 50 percent of the parent's PIA. For a child whose parent has died, the rate is 75 percent. These percentages are fixed by law and do not change based on the child's condition or needs.

The payment is rounded down to the nearest dollar. If your PIA is $1,200 per month, your child would receive $600. If your PIA is $1,201, your child still receives $600 because Social Security rounds down.

The family maximum and how it affects your child's payment

Social Security imposes a family maximum: the total amount paid to you and all your family members cannot exceed 150 to 180 percent of your Primary Insurance Amount. The exact percentage depends on your birth year and the formula Social Security applies to your record. Most family maximums fall between 150 and 180 percent.

If you are disabled and receiving $1,200 per month, and you have two children each receiving $600, the total is $2,400. If your family maximum is 175 percent of $1,200—which is $2,100—Social Security will reduce each payment proportionally so the total does not exceed $2,100. Each child might receive $450 instead of $600.

The family maximum matters most when multiple family members receive benefits: you, your spouse, and two or more children. A spouse typically receives 32.5 to 50 percent of your PIA, and each child receives 50 percent. Those payments add up quickly. You can ask Social Security to estimate your family maximum when you call or visit an office.

When your child's payment stops

Your child's SSDI payment continues only until a specific age, regardless of their disability status. If your child is in high school full-time, the payment continues until they turn 19. If they are not in school, the payment stops at age 18. Once the payment stops, it does not restart even if your child later becomes unable to work.

The payment also stops if your child's disability ends—that is, if Social Security determines they no longer meet the medical criteria for disability. Social Security conducts periodic reviews, especially for children whose conditions are expected to improve. You will receive notice before any review and can submit medical evidence to support your child's continued disability.

If you die, your child's payment continues under the survivor benefits program, not the disabled child program. The payment amount and age limits may differ slightly, but the payment itself does not stop straightforward because you have passed away.

How your child's work affects the payment

If your child works and earns above the Substantial Gainful Activity limit—which is $1,550 per month in 2024, though this amount changes yearly—Social Security may reduce or stop the payment. The limit applies to your child's own earnings, not to money they receive from you or other sources.

Below the limit, your child can work without affecting the payment. Between the limit and roughly twice the limit, Social Security deducts $1 from the payment for every $2 earned above the threshold. Above roughly twice the limit, the payment stops entirely for that month.

These rules explore only while your child is under the age limit for payment (19 if in high school, 18 otherwise). Once the payment stops due to age, work earnings no longer matter.

Cost of living adjustments and payment changes

Your child's payment increases each year if there is a Cost of Living Adjustment, or COLA. Social Security announces the COLA in October for the following year, and payments increase in January. The COLA is the same percentage for all beneficiaries and is based on inflation, not on individual circumstances.

Your child's payment can also change if your own benefit amount changes. If you return to work and earn significantly more, Social Security may recalculate your Primary Insurance Amount upward, which would increase your child's payment. If you reach full retirement age or turn 70, your benefit may increase, which increases your child's payment as well.

Changes to family circumstances—such as another child being born and receiving benefits, or a spouse starting to receive benefits—can trigger a recalculation of the family maximum, which may reduce your child's individual payment.

How to find out your child's specific payment amount

You cannot find your child's exact payment amount online. You must contact Social Security directly by calling 1-800-772-1213, visiting a local Social Security office, or creating a my Social Security account at ssa.gov and sending a message through the find inbox.

When you contact Social Security, have your Social Security number and your child's Social Security number ready. Tell the representative you want an estimate of your child's SSDI payment. They will ask about your work history and will calculate your Primary Insurance Amount, then tell you what 50 percent of that amount would be before the family maximum is applied.

If you are already receiving SSDI or have a Social Security Statement, you can use that to estimate your child's payment yourself: take your Primary Insurance Amount and divide by two. That is the starting point, though the family maximum may reduce it further if other family members also receive benefits.

Frequently Asked Questions

Does my child's disability have to be severe for them to receive the full 50 percent?

No. Social Security does not pay more or less based on severity. Your child receives 50 percent of your Primary Insurance Amount if they meet the medical definition of disability—meaning they have a condition expected to last at least 12 months or result in death, and the condition prevents substantial work. The payment amount is the same whether the disability is mild or severe.

What if I never worked or worked very little?

Your child may still receive a payment, but it will be small. Social Security calculates your Primary Insurance Amount based on your actual earnings record. If you worked only a few years or at low wages, your PIA will be low, and your child's 50 percent of that will be correspondingly low. You can check your Social Security Statement to see your estimated amount.

Can my child's payment increase if they turn 18 and are no longer in school?

No. Your child's payment does not increase at age 18. Instead, the payment stops entirely if your child is not in high school full-time. If your child is in high school, the payment continues until age 19. Once the payment stops due to age, it does not restart.

If I have multiple children on my record, will they each get 50 percent?

Each child is may have access to to 50 percent of your Primary Insurance Amount, but the family maximum may reduce that. If you have two children and the family maximum is 175 percent of your PIA, the total paid to both children combined cannot exceed that 175 percent. Social Security divides the available amount proportionally among all family members receiving benefits.

Does my child's own income or savings affect their SSDI payment?

Your child's savings and unearned income do not affect SSDI. Only work earnings above the Substantial Gainful Activity limit can reduce the payment. Gifts, inheritance, or money from you do not count as earnings and do not change the payment amount.
