The monthly payment amount depends on your earnings history, not your condition

Social Security Disability Insurance (SSDI) pays a monthly benefit based on how much you earned before you became unable to work—not on the severity of your condition or how much money you need. The Social Security Administration calculates your benefit using your average earnings over your working years. Two people with the same diagnosis can receive very different amounts.

In 2024, the average SSDI payment is around $1,550 per month, but individual payments range from roughly $700 to over $3,800 monthly. Your actual amount depends entirely on your Primary Insurance Amount (PIA), which Social Security computes from your wage record. If you earned more during your working years, your benefit will be higher. If you had lower earnings or gaps in work history, your benefit will be lower.

Key Takeaways

  • Your SSDI payment is based on your own earnings history, calculated as a percentage of what you would have earned at full retirement age if you had not become disabled.
  • The Social Security Administration sends you a detailed benefit calculation called a "benefit statement" that shows your estimated monthly amount before you file.
  • Family members—spouse, ex-spouse, or children under 19 (or 22 if in school)—may receive their own payments based on your earnings record, which does not reduce your benefit.
  • SSDI payments are adjusted each year for cost-of-living increases, which in 2024 was 3.2 percent.
  • You can request a detailed earnings record from Social Security to verify the income they used to calculate your benefit.

How Social Security calculates your monthly benefit

Social Security looks at your highest 35 years of earnings (or fewer if you have not worked that long) and adjusts them for inflation to current dollars. They then calculate your Average Indexed Monthly Earnings (AIME)—essentially your average monthly income across those years. Your PIA is then determined by explore a formula to your AIME. The formula is progressive: it replaces a higher percentage of lower earnings and a lower percentage of higher earnings.

For example, if your AIME is $2,000, Social Security applies percentages to different portions of that amount. The first portion receives roughly 90 percent replacement, the next portion receives roughly 32 percent, and amounts above that receive roughly 15 percent. This means lower-earning workers receive a higher percentage of their pre-disability income replaced, while higher-earning workers receive a lower percentage but a larger dollar amount.

You can see your estimated benefit before you file by creating a my Social Security account at ssa.gov. The account shows your earnings record and displays your estimated SSDI benefit amount based on your current age and work history. This estimate updates each year when Social Security posts your new earnings.

What happens to your benefit if you have family members

If you are approved for SSDI, your spouse, ex-spouse, or unmarried children may also receive payments based on your earnings record. A spouse can receive up to 50 percent of your PIA at full retirement age, or a reduced amount if they claim before that age. Children under 19 (or 22 if enrolled full-time in high school) can each receive up to 75 percent of your PIA.

There is a family maximum—the total amount all family members combined can receive is typically 150 to 180 percent of your PIA. If the family maximum is reached, each family member's payment is reduced proportionally, but your own benefit never changes. For example, if your PIA is $1,500 and your family maximum is $2,700, and your spouse and two children all claim, the total paid to all four of you combined cannot exceed $2,700.

Cost-of-living adjustments and how your benefit changes over time

Each January, Social Security increases all SSDI payments by a percentage tied to inflation, called a Cost-of-Living Adjustment (COLA). In 2024, the COLA was 3.2 percent. In 2023, it was 8.7 percent. The adjustment amount varies year to year based on the Consumer Price Index.

Your benefit also changes if you return to work. If you earn above the Substantial Gainful Activity (SGA) level—$1,550 per month in 2024—Social Security may determine you are no longer disabled and stop your benefits. However, SSDI includes work incentives that allow you to test your ability to work without when ready losing benefits. The Trial Work Period lets you work and earn any amount for nine months without affecting your benefit. After that, you enter the Extended Period of may be able to access, during which your benefit continues if your earnings fall below SGA, even if you had months above it.

How your benefit compares to Supplemental Security Income (SSI)

SSDI and Supplemental Security Income (SSI) are different programs with different payment rules. SSDI is based on your work history and pays the same amount regardless of how much money or property you own. SSI is a needs-based program for people with low income and limited resources, and the payment amount is reduced if you have other income or assets above certain limits.

In 2024, the maximum SSI payment is $943 per month for an individual (amounts vary by state). SSDI payments average higher but vary widely based on earnings history. Some people receive both SSDI and SSI—this is called "concurrent receipt"—if their SSDI benefit is very low. In that case, SSI tops up the SSDI payment to the SSI maximum.

Taxes on your SSDI benefit

SSDI benefits are not automatically taxed, but they can become taxable if your total income exceeds certain thresholds. If you have other income—wages, self-employment income, interest, dividends, or taxable pensions—combined with your SSDI, you may owe federal income tax on a portion of your benefits.

The threshold depends on your filing status. For a single filer, if your combined income (SSDI plus half your SSDI plus other income) exceeds $25,000, up to 50 percent of your benefits become taxable. If it exceeds $34,000, up to 85 percent become taxable. For married filers, the thresholds are $32,000 and $44,000. These thresholds have not changed since 1984, so they affect more beneficiaries over time as incomes rise.

How to find out your specific benefit amount

The most accurate way to learn your benefit amount is to create a my Social Security account at ssa.gov. You will need your Social Security number, email address, and a way to verify your identity (a phone number, state ID, or passport). Once logged in, you can view your earnings record, see your estimated SSDI benefit, and check for any errors in the income Social Security has recorded.

If you do not use online accounts, you can call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and ask for a benefit estimate. You can also visit your local Social Security office in person. Bring your Social Security card and a photo ID. Staff can print your earnings record and explain how your benefit was calculated.

Frequently Asked Questions

Can I find out my benefit amount before I file for SSDI?

Yes. Create a my Social Security account at ssa.gov to see your estimated benefit based on your current earnings record. You can also call 1-800-772-1213 and ask Social Security to mail you a benefit estimate statement. The estimate shows what you would receive if you were approved today.

Will my benefit go down if other family members claim on my record?

No. Your benefit amount never changes based on how many family members claim. However, if the family maximum is reached, each family member's individual payment is reduced proportionally. Your own payment stays the same.

What if Social Security made a mistake on my earnings record?

Request a detailed earnings record from Social Security and review it for errors. If you find a mistake, contact Social Security with proof of your actual earnings (W-2s, tax returns, or pay stubs). Social Security can correct the record, which may increase your benefit if earnings were underreported.

Does my SSDI benefit increase if my condition gets worse?

No. Your monthly payment is based on your earnings history, not the severity of your condition. Once you are approved for SSDI, your benefit amount stays the same unless you return to work, the law changes, or you receive a cost-of-living adjustment each January.

Can I receive SSDI and still work?

Yes, through work incentives. During your nine-month Trial Work Period, you can earn any amount and keep your full benefit. After that, if you earn below the SGA level ($1,550 in 2024), your benefit continues. If you earn above SGA, your benefit may stop, but you can use the Extended Period of may be able to access to test work without losing coverage.
