Your payment is based on your own earnings record, not on how disabled you are
Social Security Disability Insurance (SSDI) pays you a monthly amount that depends almost entirely on how much you earned before you stopped working. The Social Security Administration does not pay more to people who are severely disabled or less to people who are mildly disabled. Two people with identical disabilities can receive very different payments if their work histories differ.
Your payment comes from a calculation Social Security calls your Primary Insurance Amount (PIA). This number is based on your average earnings over your working years, adjusted for inflation. Social Security looks at your 35 highest-earning years (or fewer if you have not worked that long), drops the lowest earnings, and converts what remains into a monthly benefit.
The exact formula changes each year because it is tied to national wage growth. This means the payment amount for the same earnings history will be slightly different depending on what year you were born and what year you start receiving benefits.
Key Takeaways
- Your SSDI payment is calculated from your own work history and earnings, not from the severity of your disability or your current financial need.
- Social Security uses your 35 highest-earning years to calculate your benefit, adjusted for inflation at the time you turn 60 or become disabled.
- The national average SSDI payment varies by year, but you can see your own estimated amount by creating a my Social Security account online.
- If you worked very few years or earned very little, your payment will be lower than someone with a longer or higher-earning work history.
- Family members may also receive payments based on your earnings record, which can reduce the total amount available to you.
How Social Security calculates your specific amount
Social Security begins by looking at your Average Indexed Monthly Earnings (AIME). This is your average monthly income over your 35 highest-earning years, adjusted so that older earnings are brought up to reflect what they would be worth in today's dollars. If you have worked fewer than 35 years, Social Security counts the missing years as zero, which lowers your average.
Once Social Security knows your AIME, it applies a formula called a bend point formula. This formula takes your AIME and converts it into your Primary Insurance Amount. The formula is progressive, meaning it replaces a higher percentage of earnings for people who earned less. Someone who earned $20,000 a year will see a larger percentage of that income replaced than someone who earned $100,000 a year.
The bend points themselves change every year based on national wage growth. This is why two people born in different years, with identical earnings histories, will receive different benefit amounts. The year you were born determines which bend point formula applies to you.
What the national average payment tells you (and what it does not)
Social Security publishes an average SSDI payment each month. As of 2024, the average payment is in the range of $1,200 to $1,400 per month, though this number changes as new beneficiaries are added and others pass away. This average is useful only as a rough reference point.
The average does not tell you what you will receive because it includes people with vastly different work histories. Someone who worked 40 years at high wages will receive far more than someone who worked 10 years at minimum wage. The average is pulled down by people who worked very little and pulled up by people who worked their entire adult lives at good pay.
Your own payment could be significantly higher or lower than the average. The only way to know your actual estimated amount is to check your own record.
How to find your estimated payment amount
You can see Social Security's estimate of your benefit by creating a my Social Security account at ssa.gov. This account shows you your earnings record as Social Security has it on file, which is the foundation of any benefit calculation. You can also see an estimate of what you would receive at different ages if you were to become disabled today.
The estimate assumes you stop working when ready. If you continue working and earning, your benefit may increase because Social Security will use your new, higher earnings in place of lower years from earlier in your career. The estimate also assumes you have met the work requirements for SSDI, which you can verify in the same account.
If you do not have internet access or prefer to speak with someone, 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.
Why your payment might be lower than you expect
If you have not worked for 35 years, your benefit will be lower than someone who has. Social Security counts missing years as zero earnings. Someone who worked only 20 years will have 15 years of zeros factored into their average, which significantly reduces the final amount.
If you earned very little during your working years, your benefit will reflect that. SSDI does not supplement low earners to bring them up to a minimum standard of living. A person who worked part-time or at minimum wage for many years will receive a smaller payment than someone who worked full-time at higher wages.
If you have a family, your payment may be reduced if other family members are also receiving benefits on your record. Social Security has a family maximum—a cap on the total amount that can be paid to you and your family members combined. If the family maximum is reached, your payment is reduced proportionally so that the total stays within the limit.
How family members affect your payment
If you are receiving SSDI, your spouse (at any age if they are caring for a child under 16, or at age 62 or older), your children under 19 (or 19 if still in high school), and your adult children who became disabled before age 22 may also receive payments based on your earnings record.
Each family member typically receives 50% of your Primary Insurance Amount, though the exact percentage varies. However, the total paid to your entire family cannot exceed the family maximum, which is usually between 150% and 180% of your own benefit amount. If adding family members would exceed this maximum, each person's payment (including yours) is reduced proportionally.
This means that if you have a large family, you may receive less than your full Primary Insurance Amount so that the total stays within the family maximum. You can see whether a family maximum applies to you in your my Social Security account.
What happens to your payment over time
Your SSDI payment is adjusted each year for Cost of Living Adjustments (COLA). These adjustments are based on inflation as measured by the Consumer Price Index. In years when inflation is high, your payment increases more. In years when inflation is low or negative, your payment may stay the same or decrease slightly.
Your payment can also change if you return to work and earn above the Substantial Gainful Activity (SGA) level. If your earnings exceed this threshold (which varies by year but is typically around $1,550 per month), Social Security may determine that 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 all your benefits.
If you continue to receive SSDI and do not work above the SGA level, your payment will only change due to annual COLA adjustments or changes to your family situation (such as a family member turning 19 and no longer being may be able to access).
Frequently Asked Questions
Can I increase my SSDI payment by working more before I explore?
Yes, if you continue working and earning before you become disabled, those new earnings may replace lower-earning years in your record. However, you must stop working (or drop below the SGA level) to be found disabled. The benefit of higher recent earnings is offset by the fact that you must have a medical condition that prevents you from working.
What if I did not work for very long before I became disabled?
Your payment will be lower because Social Security counts the missing years as zero. However, you may still meet the work requirements for SSDI even with a short work history, depending on your age. Younger workers need fewer years of work history than older workers. Check your my Social Security account to see whether you have met the requirements.
Does my SSDI payment change if I get married or divorced?
Your own payment does not change, but your spouse may become may be able to access to receive a payment based on your record if you marry, or may lose may be able to access if you divorce. A family maximum may also explore, which could affect how much each family member receives. Contact Social Security if your family situation changes.
Is there a maximum SSDI payment?
There is no absolute maximum for an individual's SSDI payment, but there is a family maximum that caps the total amount paid to you and your family members combined. This maximum is usually 150% to 180% of your Primary Insurance Amount and varies by case.
What if Social Security has the wrong earnings in my record?
You can review your earnings record in your my Social Security account and report errors. If you find a mistake, you can request a correction by submitting documents like old tax returns or W-2 forms. Correcting errors before you explore for benefits ensures your payment is calculated correctly.
