What the monthly payment amount depends on

Your monthly Social Security Disability Insurance (SSDI) payment is based on your Primary Insurance Amount (PIA), which the Social Security Administration calculates from your lifetime earnings record. The higher your average earnings before you became unable to work, the higher your monthly payment. The calculation uses your 35 highest-earning years, adjusted for inflation.

The actual dollar amount you receive each month varies widely. In 2024, the average SSDI payment is around $1,550 per month, but this is an average—some people receive $600 monthly, others receive $3,800 or more. Your specific amount depends entirely on what you earned and when you earned it, not on your medical condition or how severe your disability is.

Social Security also adjusts all payments once per year for cost-of-living increases. This means your payment amount changes in January each year if there is an adjustment. The 2024 adjustment was 3.2 percent, but this percentage varies year to year based on inflation.

  • You can see your estimated payment amount by creating a my Social Security account online or calling Social Security directly.

How Social Security calculates your payment

Social Security begins by looking at your W-2 forms and tax records going back to age 21 (or when you started working, if later). They identify your 35 highest-earning years and calculate your average monthly earnings across those years, adjusted for inflation to today's dollars. This adjusted average is called your Average Indexed Monthly Earnings (AIME).

Next, Social Security applies a formula to your AIME to arrive at your Primary Insurance Amount. The formula uses three "bend points"—dollar thresholds where the percentage of your earnings counted changes. For example, in 2024, the formula counts 90 percent of your first $1,174 in AIME, then 32 percent of earnings between $1,174 and $7,078, then 15 percent of anything above that. These bend points change each year.

The result is your PIA—the amount you would receive at your full retirement age if you were retired. Since you are on disability, you receive your full PIA with no reduction, regardless of your age. Family members may also receive payments based on your record, which can reduce the total amount available to your household.

What happens if family members receive payments on your record

When you receive SSDI, your spouse, ex-spouse, and unmarried children under 19 (or 19 if still in high school full-time) may also receive payments based on your earnings record. Each family member receives a percentage of your PIA, but there is a family maximum—a cap on the total amount Social Security will pay to your entire household.

The family maximum is typically 150 to 180 percent of your PIA, depending on your specific situation. If your PIA is $1,500 and your family maximum is 175 percent, the total paid to you and all family members combined cannot exceed $2,625 per month. If family members' individual shares would exceed this cap, each person's payment is reduced proportionally.

This means that if you have a spouse and two children all receiving payments on your record, your own payment may be reduced so the family total does not exceed the maximum. Social Security will explain the family maximum amount when they approve your claim.

Checking your estimated payment before you explore

You can see a rough estimate of your future SSDI payment without explore. Create a free my Social Security account at ssa.gov. Once you log in, select "Benefit Estimates" and you will see your estimated retirement, survivor, and disability benefit amounts based on your current earnings record.

This estimate assumes you stop working today. If you continue working and earning, your estimate will change because Social Security recalculates your average earnings each year. The estimate also assumes you have enough work credits to may have access to for SSDI—if you do not, it will not show a disability amount.

If you do not have an online account or prefer to speak with someone, call Social Security at 1-800-772-1213 (TTY 1-800-325-0778). A representative can give you a verbal estimate over the phone, though the process takes longer than using the online tool.

Payment amounts for people who worked very little

If you have very few work credits or very low lifetime earnings, your SSDI payment will be correspondingly low. There is no minimum SSDI payment amount—Social Security calculates what you are owed based on your record, even if that amount is $100 per month or less.

Some people in this situation may also be able to receive Supplemental Security Income (SSI), a separate needs-based program that provides a federal minimum payment (currently $943 per month in 2024 for an individual, though this varies by state). SSI has strict income and resource limits, and you can receive both SSDI and SSI if your SSDI payment is very low. The two programs have different rules, so you would need to explore for SSI separately if you think you might may have access to.

How work affects your payment amount

If you work while receiving SSDI, your payment does not automatically reduce. However, if your earnings exceed the Substantial Gainful Activity (SGA) level, Social Security may determine that you are no longer disabled and stop your benefits. In 2024, the SGA level is $1,550 per month for non-blind individuals and $2,590 for blind individuals.

There is also a trial work period that allows you to test your ability to work without when ready losing benefits. During the nine-month trial work period, you can earn any amount and keep your full SSDI payment. After the trial work period ends, if your earnings stay below SGA, you continue receiving your full payment. If earnings exceed SGA, your benefits stop, though you enter a grace period where you keep your payment for that month and the next month.

The relationship between work and payment is complex and depends on how much you earn and for how long. Before you start working, contact Social Security's Work Incentives Planning and information (WIPA) program—it is free and helps you understand how work will affect your specific payment.

When your payment amount changes

Your payment amount changes in three main situations. First, Social Security adjusts all payments in January for cost-of-living increases. Second, if you return to work and your earnings record improves, Social Security recalculates your PIA each year in January, which could increase your payment. Third, if you have family members receiving payments on your record and their circumstances change (for example, a child turns 19 and stops receiving), the family maximum recalculation may increase your individual payment.

You will receive a notice each December showing your new payment amount for January. If the amount changes and you do not understand why, you can call Social Security or log into your my Social Security account to see the breakdown.

Frequently Asked Questions

Can I find out my exact payment amount before Social Security approves my claim?

No—Social Security only calculates your exact payment amount after they approve your claim and verify your work history. The my Social Security estimate is based on your current record and assumes you stop working today, so it may differ from your actual approved amount. The estimate gives you a reasonable range, but the final number comes only after approval.

Why is my SSDI payment less than my friend's if we both have the same disability?

SSDI payments are based entirely on your individual earnings history, not on your medical condition. Your friend may have earned more over their lifetime, worked more years, or had higher-paying jobs. Two people with identical disabilities can receive very different payments because their work histories are different.

Does my payment increase if my disability gets worse?

No. Once Social Security approves your SSDI claim, your payment amount is locked to your Primary Insurance Amount. Your payment does not increase if your condition worsens. It only increases with the annual cost-of-living adjustment in January, or if your work history improves and Social Security recalculates your record.

What if I think Social Security made a mistake calculating my payment?

Request a detailed earnings statement from Social Security. You can do this through your my Social Security account or by calling 1-800-772-1213. Review the statement to confirm all your W-2 earnings are recorded correctly. If you find an error, Social Security can correct it and recalculate your payment. Errors are usually caught within the first year after approval.

Will my payment stop if I move to another state or country?

Moving within the United States does not affect your payment. If you move outside the U.S., your payment may stop depending on which country you move to. Some countries have agreements with Social Security that allow payments to continue; others do not. Contact Social Security before you move internationally to confirm whether your payment will continue.
