What "National Disability Benefits" Means in the U.S. System

There is no single program called "National Disability Benefits." Instead, the federal government runs two separate programs that pay monthly cash to people with disabilities: Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI). Both are run by the Social Security Administration, but they work differently, pay different amounts, and have different rules about how much money you can have and still receive payments.

SSDI is based on your work history and the taxes you paid into Social Security while working. SSI is a needs-based program for people with low income and few assets, regardless of work history. Your monthly payment amount depends on which program you receive, your age when you became disabled, and in SSDI's case, your lifetime earnings record.

A third program, Veterans Benefits for Disability, exists separately through the Department of Veterans Affairs and pays based on service-connected disability ratings. This article focuses on SSDI and SSI, which cover the vast majority of working-age people with disabilities.

Key Takeaways

  • SSDI payments are based on your own work history and earnings, while SSI payments are based on financial need and are the same for everyone in your state (with small variations for living situation).
  • The average SSDI payment in 2024 is around $1,550 per month, but your actual payment depends on how much you earned before becoming disabled.
  • SSI pays a federal base amount of $943 per month in 2024, but most states add money on top, and some states pay significantly more.
  • You can receive both SSDI and SSI at the same time if your SSDI payment is very low, though the total is reduced by the SSI amount.
  • Your payment amount does not change based on how severe your disability is — only on your work history (SSDI) or financial need (SSI).

How SSDI Payment Amounts Are Calculated

Your SSDI payment is based on your Primary Insurance Amount (PIA), which Social Security calculates from your lifetime earnings record. The formula takes your highest 35 years of earnings, adjusts them for inflation, and then applies a bend-point formula that replaces a higher percentage of lower earnings than higher earnings. This means lower-wage workers receive a higher percentage of their pre-disability income, but the actual dollar amount still depends on how much you earned.

You can see your estimated PIA by creating an account at ssa.gov and viewing your Social Security Statement. This statement shows your earnings history year by year and estimates what you would receive at different ages. If you have not worked much, your SSDI payment will be lower. If you worked full-time at higher wages, your payment will be higher.

The maximum SSDI payment in 2024 is $3,822 per month, but fewer than 5 percent of beneficiaries receive that amount. Most people receive between $1,000 and $2,000 per month. Your payment does not increase if your disability is more severe — it only depends on your earnings history.

How SSI Payment Amounts Are Set

SSI works completely differently. The federal government sets a base payment amount, called the Federal Benefit Rate (FBR), which is $943 per month in 2024. This is the same for everyone, regardless of work history. However, most states add their own money on top of the federal amount, so your actual payment depends on which state you live in.

Some states add very little — as little as $1 or $2 per month. Other states, like California, New York, and Massachusetts, add $100 to $200 or more per month. A few states do not add anything. You can find your state's SSI rate by calling Social Security at 1-800-772-1213 or checking your state's disability agency website.

Your SSI payment also changes based on your living situation. If you live with family members who buy food and pay rent, your payment is reduced. If you live in a group home or institutional setting, your payment may be lower still. If you live alone and pay your own rent and food, you receive the full amount.

When You Can Receive Both SSDI and SSI

You can receive both programs at the same time, but this only happens when your SSDI payment is very low. Social Security calls this concurrent benefits. Here is how it works: if your SSDI payment is less than the SSI federal benefit rate ($943 in 2024), Social Security will pay you SSI to bring your total up to that amount.

For example, if you receive $600 per month in SSDI, Social Security will add $343 in SSI so your total is $943. If your state adds money to SSI, you may receive more. However, if your SSDI payment is already $943 or higher, you cannot receive SSI at all.

Concurrent benefits are common for people who had very low earnings before becoming disabled or who became disabled before they had time to build a substantial work history. If you are receiving SSDI and think your payment is unusually low, contact Social Security to ask whether you also meet the financial requirements for SSI.

How Work History Affects Your Payment

SSDI payments are tied directly to your earnings record. Social Security looks at your highest 35 years of earnings (or fewer if you have not worked that long). Years with no earnings count as zeros, which lowers your average. This is why people who took time out of the workforce — to raise children, attend school, or deal with illness — often receive lower SSDI payments than people who worked continuously.

Your payment is calculated the same way whether you became disabled at age 25 or age 55. However, if you became disabled very young, you may have fewer years of earnings to count, which typically results in a lower payment. There is no way to increase your SSDI payment once you are approved, except through the annual cost-of-living adjustment that all beneficiaries receive.

SSI does not care about work history at all. You can receive the full SSI payment even if you have never worked, as long as you meet the disability and financial requirements.

Cost-of-Living Adjustments and Payment Changes

Both SSDI and SSI payments increase each year based on the Cost-of-Living Adjustment (COLA). Social Security announces the COLA in October for the following year, and payments increase in January. In 2024, the COLA was 3.2 percent. In 2023, it was 8.7 percent. The COLA varies year to year based on inflation.

Your payment can also change if your circumstances change. If you return to work and earn above the Substantial Gainful Activity (SGA) level — $1,550 per month in 2024 — your SSDI payments will stop after a trial work period. If you are receiving SSI and your income or assets increase, your SSI payment will decrease or stop. If you move to a different state, your SSI payment may change because states set different rates.

Social Security sends you a notice whenever your payment changes. Keep these notices and compare them to your bank deposits to make sure the amount is correct.

Frequently Asked Questions

Can I find out what my SSDI payment will be before I explore?

Yes. Create a my Social Security account at ssa.gov and view your Social Security Statement. It shows your earnings history and estimates your SSDI payment at different ages. If you do not have an account, you can call Social Security at 1-800-772-1213 and ask for an estimate based on your work history.

Why is my SSDI payment lower than my friend's, even though we both have the same disability?

SSDI payments are based entirely on work history and earnings, not on disability type or severity. Your friend likely earned more money during their working years, had fewer years with zero earnings, or became disabled at an older age. Two people with identical disabilities can receive very different SSDI amounts.

What if I think my payment amount is wrong?

Request a detailed benefit calculation from Social Security by calling 1-800-772-1213 or visiting your local Social Security office. They can show you the earnings record they used and explain how your payment was calculated. If you find an error in your earnings history, you can request a correction, which may increase your payment.

Do I get more money if my disability is more severe?

No. Both SSDI and SSI payment amounts are based on work history (SSDI) or financial need (SSI), not on how severe your disability is. You must meet the disability threshold to receive benefits at all, but once approved, severity does not affect your monthly payment.

Can my SSDI payment go down after I am approved?

Your SSDI payment can decrease if you return to work and earn above the SGA level, which triggers a trial work period and eventual benefit termination. Otherwise, your SSDI payment only increases with the annual COLA. It does not decrease due to disability severity or other factors.
