Your payment amount depends on your work history and earnings record, not on how disabled you are

The Social Security Administration calculates your SSDI payment based on your Primary Insurance Amount (PIA), which comes from how much you earned and paid into Social Security before you became unable to work. Two people with the same condition can receive very different amounts. Someone who worked for 30 years at higher wages will receive more than someone who worked fewer years or at lower wages.

Your payment is not based on your medical condition, your living expenses, or how much you need. It is based entirely on your past earnings record. The SSA uses a formula that takes your highest 35 years of earnings, adjusts them for inflation, and calculates an average. That average becomes your PIA.

The average SSDI payment in 2024 is around $1,550 per month, but this varies widely. Some people receive $600 per month; others receive $3,800 or more. The only way to know your specific amount is to request a benefit estimate from Social Security or to check your account on ssa.gov.

Key Takeaways

  • Your SSDI payment is calculated from your earnings record before you became disabled, not from your medical condition or current needs.
  • You can see an estimate of your payment by creating a my Social Security account at ssa.gov or by calling Social Security at 1-800-772-1213.
  • Your payment amount does not change based on how severe your disability is or whether you live alone or with family.
  • If you worked for fewer years or at lower wages, your payment will be lower than the national average, even if you are approved for SSDI.
  • Once you start receiving SSDI, your payment amount is adjusted each year for cost-of-living increases, but the base amount stays tied to your earnings history.

How Social Security calculates your Primary Insurance Amount

The SSA uses a three-step process. First, they take your 35 highest-earning years (adjusted for inflation to current dollars). If you worked fewer than 35 years, they count zeros for the missing years, which lowers your average. Second, they calculate your Average Indexed Monthly Earnings (AIME) by dividing your total adjusted earnings by 420 months. Third, they explore a bend point formula to your AIME to arrive at your PIA.

The bend point formula is progressive: it replaces a higher percentage of your earnings if you earned less, and a lower percentage if you earned more. In 2024, the formula is roughly 90 percent of the first $1,174 of your AIME, plus 32 percent of earnings between $1,174 and $7,078, plus 15 percent of earnings above $7,078. These bend points change each year.

This means someone who earned $20,000 per year for 35 years will receive a higher percentage of their average earnings than someone who earned $80,000 per year. But in absolute dollars, the higher earner still receives more.

What affects your payment amount

Your work history is the main factor. If you took time out of the workforce to raise children, attend school, or care for a family member, those years count as zeros in the calculation. If you worked part-time or at minimum wage, your average earnings are lower. If you worked only 20 years instead of 35, the missing 15 years are zeros.

Your age when you start receiving SSDI does not change your PIA, but it does affect your payment if you also receive Social Security retirement benefits later. If you are approved for SSDI before full retirement age and continue working, your payment may be reduced if you earn above a certain threshold (in 2024, $23,400 per year). Once you reach full retirement age, there is no earnings limit.

Family members may also receive payments based on your record. If you have a spouse age 62 or older, or a spouse of any age caring for your child under 16, they may receive up to 50 percent of your PIA. Each of your unmarried children under 19 (or 19 if still in high school) may receive up to 50 percent of your PIA. However, the total paid to your entire family cannot exceed 150 to 180 percent of your PIA.

How to find out your specific payment amount

The fastest way is to create a my Social Security account at ssa.gov. Once you log in, you can view your earnings record and see an estimate of your benefits. This estimate is based on your actual earnings history and is updated each year. You do not need to be approved for SSDI to see this estimate.

If you do not have an online account, you can call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and ask for a benefit estimate. You will need your Social Security number and date of birth. The representative can tell you what your PIA would be based on your current earnings record.

You can also request a detailed Social Security Statement by mail, though this takes longer. Go to ssa.gov and select "Request a replacement Social Security Statement." The statement shows your earnings history year by year and includes an estimate of your SSDI benefit.

What happens to your payment after you are approved

Once you are approved for SSDI, your payment amount is set based on your PIA at the time of approval. Each January, Social Security adjusts all SSDI payments by the Cost-of-Living Adjustment (COLA), which is tied to inflation. In 2024, the COLA was 3.2 percent. In 2023, it was 8.7 percent. The COLA varies year to year and is announced in October for the following year.

Your payment does not increase if your condition worsens or if your living situation changes. It does not decrease if you improve or if you move to a less expensive area. The only reasons your payment changes are the annual COLA, a change in your family composition (if family members start or stop receiving benefits on your record), or a change in your work earnings if you are still working.

If you return to work and earn above the threshold, your payment may be reduced or suspended. If you earn below the threshold, you continue to receive your full SSDI payment. Once you reach full retirement age, your SSDI converts to Social Security retirement benefits at the same amount.

Payment amounts for people with limited work history

If you have not worked much or worked only recently, your SSDI payment will be lower than the national average. Someone who worked only 10 years will have 25 years of zeros in the calculation, which significantly reduces the average. Someone who worked at minimum wage throughout their career will have a lower average than someone who earned more.

There is no minimum SSDI payment amount, but there is a minimum for people age 62 and older who have never worked enough to earn their own benefit. These people may receive a deemed filing benefit based on a spouse's or parent's record, with a floor of about $50 per month. However, this applies only in specific family situations and does not explore to most SSDI recipients.

If your work history is very limited, you may want to check whether you could receive Supplemental Security Income (SSI) instead. SSI is a needs-based program with different rules and does not require a work history. You can receive both SSDI and SSI if your SSDI payment is below a certain threshold, though the rules are complex.

How your payment compares to other information programs

SSDI is typically higher than SSI, which is a needs-based program with a maximum federal payment of $943 per month in 2024 (though some states add more). SSDI is also higher than unemployment insurance, which varies by state but averages around $400 to $500 per week. However, SSDI is usually lower than what you would earn if you were working full-time.

SSDI is also different from workers' compensation, which is paid by your employer's insurance and is based on your injury or illness at work. Workers' compensation and SSDI can sometimes be received together, though there are offset rules that may reduce one or both.

Frequently Asked Questions

Can I see my SSDI payment amount before I am approved?

Yes. You can create a my Social Security account at ssa.gov and view your benefit estimate based on your earnings record. This estimate shows what you would receive if you were approved today. The actual amount may differ slightly once you are approved, depending on when your approval date is set.

Will my payment increase if my condition gets worse?

No. Your SSDI payment is based on your earnings history, not on the severity of your condition. The only increases are the annual cost-of-living adjustments in January. If your condition changes, it does not affect your payment amount.

What if I worked in another country before moving to the United States?

Social Security generally counts only earnings from U.S. employment. However, some countries have agreements with the United States that allow Social Security to count work history from those countries. You can ask Social Security whether your foreign work history counts by calling 1-800-772-1213.

Can my spouse or children receive money from my SSDI?

Yes. Your spouse age 62 or older, or any age if caring for your child under 16, can receive up to 50 percent of your PIA. Each unmarried child under 19 (or 19 if in high school) can receive up to 50 percent of your PIA. The total family payment cannot exceed 150 to 180 percent of your PIA.

Does my SSDI payment change if I move to a different state?

No. SSDI is a federal program, so your payment is the same regardless of where you live. However, some states add money to SSI payments, so if you receive both SSDI and SSI, a move might affect your SSI amount.
