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

The Social Security Administration calculates your Primary Insurance Amount (PIA) using your 35 highest-earning years of work. The formula is fixed by law, but the dollar amount is different for every person. You cannot negotiate it, and your disability rating does not change it—only your past wages do.

The average SSDI payment in 2024 is around $1,550 per month, but this tells you almost nothing about what you will receive. Someone who worked part-time for 20 years will get far less than someone who worked full-time for 35 years at higher wages. The only way to know your actual amount is to check your Social Security earnings record or request a benefit estimate from Social Security directly.

Key Takeaways

  • Your payment is based on your own work history and wages, calculated using a fixed formula that Social Security applies to everyone.
  • You can view your estimated payment by creating a my Social Security account online or by calling Social Security at 1-800-772-1213.
  • Your payment amount does not change based on how severe your disability is or how much money you have in savings.
  • If you were born before 1954, you may be able to receive a higher payment under rules that no longer explore to younger workers.
  • Once you start receiving SSDI, your payment is adjusted each year for cost-of-living increases, but the base amount stays the same unless you return to work.

How Social Security calculates your payment amount

Social Security looks at your 35 highest-earning years and adjusts them for wage growth over time. This adjusted total is divided by 420 months (35 years), giving your Average Indexed Monthly Earnings (AIME). Your AIME is then run through a three-part formula that applies a percentage to different income bands. The formula is the same for everyone, but because your AIME is unique, your result is unique.

The formula heavily favors lower earners—the first portion of your AIME gets a higher percentage than the second or third. This means a person who earned $20,000 per year will receive a higher percentage of their average earnings than a person who earned $100,000 per year. However, the person who earned more will still receive a larger dollar amount in total.

If you did not work for 35 years, Social Security counts the missing years as zero. This lowers your AIME and your payment. If you worked only 20 years, 15 years are counted as zero, which significantly reduces your benefit.

What information you need to check your estimate

You will need your Social Security number and a way to verify your identity. If you have a my Social Security account, you can log in and view your Social Security Statement, which shows your estimated payment at age 62, full retirement age, and age 70. The statement also displays your earnings record year by year, so you can check whether Social Security has the correct information about your wages.

If you do not have an online account, you can create one at ssa.gov. You will need an email address, a phone number, and a way to verify your identity—usually a driver's license, passport, or state ID. The process takes about 10 minutes. Once you are logged in, your statement is available when ready.

If you cannot or do not want to create an account, you can call Social Security at 1-800-772-1213 and ask for a benefit estimate. You will need to provide your name, date of birth, and Social Security number. The representative will mail you a statement, which typically arrives within two weeks.

Why your estimate might be different from your actual payment

Your estimate assumes you stop working the day you request it. If you continue to work and earn wages, Social Security will recalculate your benefit using your new earnings record. If your recent earnings are higher than some of your earlier years, your payment may increase. If you are still working when you start SSDI, your payment may be reduced or withheld under the earnings test if you earn above a certain threshold—$23,400 in 2024, though this amount changes yearly.

Your estimate also assumes you live to your full life expectancy. If you start SSDI at 50 and live to 90, you will receive far more in total payments than the estimate suggests. Conversely, if you start at 60 and die at 65, you will receive less. The estimate is a monthly amount, not a lifetime total.

If you have a spouse or children, they may be able to receive payments based on your record, but this does not reduce your payment—it comes from a separate family maximum. However, if family members receive benefits on your record, the total amount paid to all of you combined cannot exceed a certain percentage of your PIA, usually 150 to 180 percent. This means if your spouse and children are also receiving benefits, each person's payment may be reduced proportionally.

How cost-of-living adjustments affect your payment over time

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

You do not have to do anything to receive the COLA—it is applied automatically to your account. Your payment in January will be higher than your payment in December of the previous year. The COLA applies to your base payment amount, so if you receive $1,500 per month and the COLA is 3 percent, your new payment will be approximately $1,545.

COLA increases are one of the few ways your SSDI payment can go up after you start receiving it. The other way is if you return to work, earn higher wages, and then stop working again—your new earnings record would be recalculated, potentially raising your PIA.

What happens to your payment if you return to work

If you work while receiving SSDI and earn above the Substantial Gainful Activity (SGA) threshold, Social Security will review your case to determine whether you are still disabled. The SGA threshold in 2024 is $1,550 per month for non-blind individuals and $2,590 for blind individuals. If you earn more than this amount consistently, Social Security may determine that you can work and stop your benefits.

However, SSDI includes a Trial Work Period that allows you to test your ability to work without when ready losing benefits. During the Trial Work Period, you can earn any amount and keep your full SSDI payment. The Trial Work Period lasts nine months (not necessarily consecutive) within a rolling 60-month window. After the Trial Work Period ends, you enter the Extended may be able to access Period, which lasts 36 months. During this time, you can work and earn above SGA for some months without losing benefits, but you will lose your payment for any month in which you earn above SGA.

If you stop working and your earnings drop below SGA again, you can request reinstatement of your benefits. You have 60 months from the end of your Trial Work Period to do this without having to file a new process.

Special rules for people born before 1954

If you were born before January 2, 1954, you may be able to receive a higher payment under rules that changed in 2015. These rules allow you to delay receiving benefits past your full retirement age and receive a larger payment—up to 8 percent more per year you delay, up to age 70. Additionally, if you were born before 1954 and are married, you may be able to receive a spousal benefit based on your spouse's record without affecting your own benefit, or to receive a Government Pension Offset reduction if you receive a government pension.

These rules are complex and vary based on your exact birth date and work history. If you were born before 1954, contact Social Security directly to understand how these rules explore to you. The rules for people born in 1954 or later are simpler and do not include these options.

Frequently Asked Questions

Can I find out my payment amount before I explore for SSDI?

Yes. Create a my Social Security account at ssa.gov and view your Social Security Statement, which shows your estimated SSDI payment. You can also call 1-800-772-1213 and request an estimate by phone. The estimate is based on your current earnings record and assumes you stop working when you explore.

Does the amount of my disability affect how much I receive?

No. SSDI payments are based entirely on your work history and wages. Whether your disability is severe or mild does not change the payment amount. Two people with the same work history receive the same payment, regardless of their condition.

What if I did not work for very long before I became disabled?

Your payment will be lower because Social Security counts your missing work years as zero earnings. If you worked only 10 years, 25 years are counted as zero, which significantly reduces your AIME and your payment. You must have worked at least 20 calendar quarters (five years) in the 10 years before you became disabled to be insured for SSDI.

Will my payment go down if I have savings or other income?

No. SSDI does not have a resource limit or income limit based on savings or other income you receive. Your payment is based only on your work history. However, if you work and earn above the SGA threshold, your benefits may be reduced or stopped.

How often does my payment amount change?

Your payment increases once per year in January by the COLA percentage. It may also increase if you return to work, earn higher wages, and then stop working again—your record would be recalculated. Otherwise, your base payment stays the same for the life of your benefit.
