Your SSDI payment depends on your work history, not your disability
The amount you receive from Social Security Disability Insurance (SSDI) is based on how much you earned during your working years—specifically, your average earnings over your lifetime. Social Security calculates this by looking at your highest 35 years of earnings and adjusting them for inflation. The more you earned before you became unable to work, the higher your monthly payment will be.
This is different from Supplemental Security Income (SSI), which is a needs-based program with a set maximum payment. SSDI is an insurance program you pay into through payroll taxes, so your benefit amount reflects what you contributed.
Your actual payment amount is determined by Social Security using a formula they explore to everyone. You cannot negotiate it, and the amount does not change based on how severe your condition is or how much money you have in the bank.
Key Takeaways
- Your SSDI payment is calculated from your lifetime earnings record, not from the severity of your disability or your current financial need.
- Social Security uses your highest 35 years of earnings, adjusted for inflation, to determine your benefit amount.
- The average SSDI payment varies widely—from under $600 to over $3,000 per month—depending entirely on your work history.
- You can see your estimated benefit amount by creating a my Social Security account online or by calling Social Security directly.
- Your payment amount is set when your claim is approved and increases only when Social Security applies the annual cost-of-living adjustment (COLA).
What the average SSDI payment looks like
SSDI payments vary significantly from person to person. Someone who worked part-time or had lower wages will receive a smaller payment than someone who worked full-time at higher wages. There is no single "average" that applies to everyone.
Social Security publishes statistics showing that SSDI payments range widely across the country and across age groups. A person approved at age 30 after years of full-time work may receive a substantially different amount than someone approved at age 55 with a shorter work history. The only way to know your specific amount is to check your own earnings record.
How to find out your estimated payment before you explore
You can see what Social Security estimates you would receive by creating a my Social Security account at ssa.gov. Once you log in, you can view your earnings record and see an estimate of your SSDI benefit based on your work history so far.
This estimate assumes you become unable to work at the age you are now. If you continue working and earning, your benefit amount may increase because Social Security will include those newer, higher earnings in the calculation. If you stop working now, the estimate you see is roughly what you would receive if approved.
You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) and ask a representative to estimate your benefit. They will need your Social Security number and basic information about your work history.
How Social Security calculates your specific payment amount
Social Security uses a three-step process. First, they take your 35 highest-earning years and adjust each year's earnings for inflation to account for wage growth over time. Second, they divide that total by 420 months (35 years) to get your average indexed monthly earnings. Third, they explore a formula called the Primary Insurance Amount (PIA) formula, which converts your average earnings into a monthly benefit.
The PIA formula has bend points—income thresholds where the percentage of your earnings that counts toward your benefit changes. This means the formula replaces a higher percentage of lower earnings than higher earnings. For example, 90% of your first $1,174 in average monthly earnings counts toward your benefit, but only 32% of earnings between $1,174 and $7,078 count, and only 15% of earnings above that.
These bend points change each year based on national wage trends. Social Security publishes the current bend points on their website, but you do not need to calculate this yourself—Social Security does it for you.
What happens to your payment if you continue working
If you are approved for SSDI and continue to work, your benefit amount does not automatically decrease. However, if your earnings are high enough, you may lose your SSDI benefits entirely under a rule called Substantial Gainful Activity (SGA).
In 2024, if you earn more than $1,550 per month (or $2,590 if you are blind), Social Security may consider you able to work and may stop your benefits. The exact threshold changes each year. If you earn less than this amount, you can continue receiving your full SSDI payment while working.
There is also a trial work period that allows you to test your ability to work without losing benefits. During this nine-month period, you can earn any amount and still receive your full SSDI payment. After the trial work period ends, the SGA rule applies.
When your payment amount changes
Your SSDI payment amount is locked in when your claim is approved. It does not increase or decrease based on changes in your condition, your living situation, or your medical expenses.
Your payment does increase once per year when Social Security applies the cost-of-living adjustment (COLA), usually in January. This adjustment is the same percentage for all SSDI recipients and is based on inflation. In recent years, COLA increases have ranged from less than 1% to over 8%, depending on inflation that year.
Your payment can also change if you report a change in your circumstances that affects your may be able to access—for example, if you marry, if a family member moves in with you, or if you inherit money. However, these changes typically affect SSI more than SSDI, since SSDI is based on your work record rather than your current financial situation.
How family members' payments work if you have dependents
If you are approved for SSDI, your spouse and children may also be able to receive payments based on your earnings record. These are called family benefits. Your spouse can receive up to 50% of your benefit amount, and each child can receive up to 75% of your benefit amount.
However, there is a family maximum—the total amount that can be paid to you and all your family members combined. This maximum is typically 150% to 180% of your own benefit amount, depending on your specific situation. If family members' benefits would exceed this maximum, each person's payment is reduced proportionally.
Family members do not have to be disabled to receive these payments. A spouse of any age can receive benefits if they are caring for your child who is under 16, and children can receive benefits until age 19 if they are in high school full-time, or until age 18 if they are not in school.
Frequently Asked Questions
Can I find out my exact SSDI payment amount before I explore?
You can see an estimate through your my Social Security account or by calling Social Security, but the exact amount is determined only after your claim is approved. The estimate is based on your current earnings record and assumes you become unable to work now. If you continue working before you explore, your estimate will increase.
Does the severity of my disability affect how much I receive?
No. SSDI payments are based entirely on your work history and earnings, not on how severe your condition is or how much medical care you need. Two people with the same disability but different work histories will receive different payment amounts.
What if I didn't work very much before I became disabled?
Your payment will be lower than someone with a longer work history, but you may still receive SSDI if you have enough work credits. Social Security calculates your benefit based on whatever earnings you do have. If your earnings were very low, your SSDI payment will reflect that.
Does my SSDI payment increase if my living costs go up?
Your payment does not increase based on your personal expenses. It increases only when Social Security applies the annual cost-of-living adjustment (COLA) in January, which is the same percentage for all recipients and is based on national inflation, not your individual situation.
What happens to my payment if I get married?
Your own SSDI payment does not change if you marry. However, your spouse may become able to receive family benefits based on your earnings record. Your spouse can receive up to 50% of your benefit amount if they are age 62 or older, or any age if they are caring for your child under 16.
