Your SSDI payment is based on your own earnings history, not on need or disability type

The Social Security Administration calculates your Social Security Disability Insurance (SSDI) payment using the same formula it uses for retirement benefits. The amount depends entirely on how much you earned during your working years—specifically, your average earnings over your 35 highest-earning years. Two people with the same disability can receive very different monthly payments because they had different careers.

The SSA does not adjust your payment based on how severe your disability is, whether you have dependents, or how much money you need to live. A person who worked full-time for 40 years will receive more than someone who worked part-time for 20 years, even if both are unable to work now.

Your payment is recalculated once per year in October, when the SSA applies the annual cost-of-living adjustment (COLA). This adjustment changes every year based on inflation. In recent years, COLA increases have ranged from less than 1 percent to over 8 percent, but this varies and is not may provide.

Key Takeaways

  • Your SSDI payment amount is based on your lifetime earnings record, not on how disabled you are or how much money you need.
  • The SSA uses your 35 highest-earning years to calculate your Primary Insurance Amount (PIA), which is your base monthly payment.
  • Family members may receive payments on your record if they are your spouse, ex-spouse, or unmarried child under 19 (or 19 if still in high school), but this does not reduce your payment.
  • Your payment increases each October when the SSA applies a cost-of-living adjustment, though the percentage varies year to year.
  • You can see your estimated payment before you file by creating a my Social Security account and viewing your earnings record.

How the SSA calculates your Primary Insurance Amount

The SSA starts with your Average Indexed Monthly Earnings (AIME). This is your average monthly income over your 35 highest-earning years, adjusted for inflation. If you worked fewer than 35 years, the SSA counts the missing years as zero, which lowers your average.

Once the SSA has your AIME, it applies a formula called a bend point formula. This formula takes your AIME and converts it into your Primary Insurance Amount (PIA)—your monthly payment before any reductions. The bend points change each year and are different for people born in different years. The formula is progressive, meaning it replaces a higher percentage of earnings for people who earned less during their working years.

For example, if your AIME is $2,000, the SSA might replace 90 percent of the first $1,174, then 32 percent of earnings between $1,174 and $7,078, then 15 percent of anything above that. The exact bend points depend on your birth year and the current year. You cannot look up your own bend points easily, but the SSA publishes them annually on its website.

What reduces your SSDI payment

Several circumstances can lower your monthly payment. If you were born before 1954 and you also receive a government pension—such as from a job where you did not pay Social Security taxes—the SSA may reduce your SSDI payment under the Government Pension Offset (GPO). This reduction can be substantial and is one of the most common reasons a beneficiary's payment is lower than expected.

If you continue to work while receiving SSDI, your payment will not be reduced, but you must report your earnings. Once your earnings exceed the Substantial Gainful Activity (SGA) threshold—which is $1,550 per month in 2024, though this amount changes annually—the SSA may determine that you are no longer disabled and stop your benefits. The SGA threshold is the same regardless of your disability type.

If you were convicted of a crime and imprisoned for more than 30 days, your SSDI payment stops while you are in prison. It resumes the month after your release.

When family members can receive payments on your record

If you are receiving SSDI, your spouse, ex-spouse, and unmarried children may also receive payments based on your earnings record. These payments do not come out of your payment—the SSA adds them to the total it pays your household. Each family member typically receives up to 50 percent of your Primary Insurance Amount, though the exact percentage depends on their relationship to you and their age.

Your spouse can receive a payment at any age if they are caring for your child who is under 16 (or 19 if the child is in high school). Your ex-spouse can receive a payment if you were married for at least 10 years, you are both at least 62 years old, and you are not currently married. Your unmarried children can receive payments until they turn 18, or 19 if they are still in high school full-time, or at any age if they became disabled before age 22.

There is a family maximum—a cap on the total amount the SSA will pay to your entire family on your record. This maximum is usually 150 to 180 percent of your Primary Insurance Amount. If family payments would exceed this maximum, each family member's payment is reduced proportionally.

How to find out what you will receive before you file

The most accurate way to see your estimated SSDI payment 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 SSDI payment. This estimate is based on your actual work history and uses the current bend points and formulas.

Your earnings record shows every year you worked and how much you earned. Check it for errors—if the SSA has recorded your earnings incorrectly, your payment will be too low. You can correct errors by contacting the SSA with documentation like W-2 forms or tax returns. Corrections must usually be made within three years, three months, and 15 days of the year the earnings were reported.

If you do not have a my Social Security account, you can request a paper statement by calling the SSA at 1-800-772-1213 or visiting your local Social Security office. The paper statement takes about two weeks to arrive by mail.

Cost-of-living adjustments and how they affect your payment

Every October, the SSA announces the annual cost-of-living adjustment (COLA) and applies it to all SSDI payments starting in December. The COLA is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from July, August, and September. If inflation was high during those months, the COLA will be high. If inflation was low or prices fell, the COLA will be low or zero.

The COLA applies to your Primary Insurance Amount and to all family members' payments on your record. It does not explore to Supplemental Security Income (SSI), which is a different program with its own rules. If you receive both SSDI and SSI, your SSDI payment increases with COLA, but your SSI payment may be reduced if your SSDI increase pushes your total income above the SSI limit.

You cannot predict the COLA in advance because it depends on inflation data that has not yet been released. The SSA announces the COLA in October for the following year. Recent COLA increases have ranged from 0 percent (in 2011) to 8.7 percent (in 2023), but these are historical figures and do not predict future adjustments.

Taxes on your SSDI payment

SSDI payments are not automatically taxed, but you may owe federal income tax on your benefits if your combined income exceeds certain thresholds. Combined income means your adjusted gross income plus nontaxable interest plus half of your SSDI benefits.

If you are single and your combined income is between $25,000 and $34,000, you may owe tax on up to 50 percent of your benefits. If your combined income exceeds $34,000, you may owe tax on up to 85 percent of your benefits. If you are married filing jointly, the thresholds are $32,000 and $44,000. These thresholds have not changed since 1984 and do not adjust for inflation.

If you also receive income from work, pensions, or investments, you are more likely to owe tax on your SSDI. You can request that the SSA withhold federal income tax from your payment to avoid owing a large amount at tax time. Contact the SSA to set up withholding.

Frequently Asked Questions

Can I find out my SSDI payment amount without filing?

Yes. Create a my Social Security account at ssa.gov and view your earnings record and estimated payment. The estimate is based on your actual work history and is usually accurate within a few dollars. If you do not have an online account, call the SSA at 1-800-772-1213 to request a paper statement.

Why is my SSDI payment lower than I expected?

The most common reasons are: you worked fewer than 35 years (missing years count as zero), you earned less during your working years than you remembered, you receive a government pension that triggers the Government Pension Offset, or the SSA made an error in recording your earnings. Request a paper statement or check your my Social Security account to see your actual earnings record and verify it is correct.

Do family members' payments reduce my SSDI payment?

No. Your payment stays the same regardless of whether family members receive payments on your record. The SSA pays family members separately from your payment. However, there is a family maximum—a cap on the total amount paid to your entire family—so if family payments would exceed this maximum, each family member's payment is reduced.

What happens to my SSDI payment if I go back to work?

Your payment does not stop when ready. You can earn up to the Substantial Gainful Activity (SGA) threshold—$1,550 per month in 2024—without risking your benefits. If you earn more than this for nine months, the SSA may determine you are no longer disabled and stop your benefits. You must report all earnings to the SSA.

Will my SSDI payment increase every year?

Your payment increases each October when the SSA applies the annual cost-of-living adjustment (COLA). The COLA percentage varies year to year based on inflation. In years when inflation is very low or prices fall, the COLA can be zero or very small. Recent COLA increases have ranged from less than 1 percent to over 8 percent.
