The average SSDI payment in 2024 is around $1,550 per month, but your payment will likely differ

Social Security calculates your SSDI payment based on your own earnings record, not on a fixed amount everyone receives. The Primary Insurance Amount (PIA) — the formula Social Security uses — takes your highest 35 years of earnings, adjusts them for inflation, and converts them into a monthly benefit. Someone who worked at minimum wage for 20 years will receive far less than someone who earned six figures. Someone who never worked will receive nothing.

The $1,550 figure is a national average. It masks real variation: some people receive $600 per month, others receive $3,800. Your payment depends entirely on what you earned before you became disabled. If you stopped working at 25 and are now 45, Social Security counts 10 years of actual earnings and 25 years of zeros. That pulls your average down.

You cannot see your exact payment amount until Social Security approves your claim. You can estimate it using the Social Security Administration's online calculator, which pulls your actual earnings record. But the estimate is only as good as the earnings data Social Security has on file — and that data is sometimes wrong.

Key Takeaways

  • Your SSDI payment is based on your lifetime earnings record, so two people with the same disability can receive very different amounts.
  • The national average of around $1,550 per month includes people who earned nothing and people who earned six figures, so it tells you little about what you will receive.
  • You can estimate your payment using the Social Security Administration's online calculator before you file a claim.
  • Your payment amount does not change based on how severe your disability is or how much money you have in savings.
  • If you worked for a government employer that did not pay Social Security taxes, the Windfall Elimination Provision may reduce your payment.

How Social Security calculates your payment amount

Social Security takes your 35 highest-earning years, adjusts each year's earnings for inflation using a national wage index, and then averages them across 420 months (35 years × 12 months). That average is your Average Indexed Monthly Earnings (AIME). The AIME then goes into a formula — called the bend points formula — that converts it into your Primary Insurance Amount.

The bend points formula is progressive. It replaces a higher percentage of low earnings than high earnings. If your AIME is $800, you might receive 90 percent of that. If your AIME is $5,000, you might receive 32 percent of that. The exact percentages and the dollar thresholds where they change are called bend points, and they adjust each year for wage growth.

The result is your Primary Insurance Amount — the amount you receive at your full retirement age if you were to claim retirement benefits. For SSDI, Social Security uses that same amount, regardless of your age. A 25-year-old and a 65-year-old with identical earnings records receive identical SSDI payments.

Why your payment might be lower than the average

If you have fewer than 35 years of work history, Social Security counts the missing years as zeros. Someone who worked 20 years and then became disabled has 15 years of zeros in the calculation, which lowers the AIME and therefore the payment. The more years you were out of the workforce before disability, the lower your payment will be.

If you earned below the national average wage in the years you did work, your AIME will be lower. Someone who worked part-time or in a low-wage job for 35 years will have a lower AIME than someone who worked full-time in a higher-wage job.

If you worked for a government employer — a state, county, or city agency — that did not pay into Social Security, the Windfall Elimination Provision (WEP) may reduce your SSDI payment. The WEP assumes that government pensions already replace some of your income, so it lowers the bend points formula. Not all government workers are affected; the rules depend on when you were hired and what type of work you did. If you think WEP applies to you, ask Social Security to calculate your payment both with and without it.

What happens to your payment if you work while receiving SSDI

SSDI has a work incentive called the Trial Work Period. For nine months (not necessarily consecutive), you can earn any amount and keep your full SSDI payment. After the Trial Work Period ends, Social Security applies the Substantial Gainful Activity (SGA) test: if you earn more than $1,550 per month in 2024 (the threshold varies by year), Social Security will assume you are no longer disabled and will stop your benefits.

The SGA threshold is a bright line, not a judgment call. If you earn $1,551, you fail the test. If you earn $1,549, you pass. The amount you receive in SSDI does not affect the SGA calculation — only your work earnings matter.

After your Trial Work Period ends, you also have a Grace Period — usually nine months — during which you can earn above SGA and keep your benefits. After the Grace Period, if you are still earning above SGA, your benefits will stop. You can request reinstatement within five years if your earnings drop back below SGA.

How your SSDI payment interacts with other benefits

If you are receiving SSDI, you become may be able to access for Medicare after 24 months of benefits, regardless of your age. Medicare is separate from SSDI and costs nothing to join at that point. Your SSDI payment does not change when you turn Medicare-may be able to access.

If you have a spouse or children, they may be able to receive benefits on your record — called family benefits. A spouse at full retirement age can receive up to 50 percent of your Primary Insurance Amount. Children under 19 (or 19 if still in high school) can each receive up to 75 percent. However, there is a family maximum: the total amount paid to you and all family members combined cannot exceed 150 to 180 percent of your Primary Insurance Amount. If the family maximum is reached, each family member's payment is reduced proportionally.

If you are also receiving a pension from work that was not covered by Social Security — such as a government pension — the Government Pension Offset (GPO) may reduce any spousal or survivor benefits you are may have access to to on someone else's record. The GPO does not affect your own SSDI payment.

How to estimate your payment before you file

The Social Security Administration publishes a Benefit Estimator tool on its website at ssa.gov. You create a my Social Security account, log in, and the tool shows you an estimate based on your actual earnings record. The estimate assumes you continue working at your current pace until your full retirement age, so if you are about to stop working due to disability, the estimate will be too high.

You can also request a detailed Social Security Statement from the agency, which shows your year-by-year earnings history and an estimate of your benefits at different ages. The Statement is useful for catching errors in your earnings record — if Social Security has recorded your income incorrectly, your payment will be wrong. You can correct errors by submitting W-2s or tax returns to Social Security.

The estimate is not a promise. Social Security will recalculate your payment when you file, using your actual earnings through the month you file. If you have worked since the estimate was generated, your payment may be higher. If you have not worked, it will be lower.

Payment amounts for people with limited work history

If you have never worked or worked very little, you may not be may be able to access for SSDI at all. SSDI requires that you have worked long enough and recently enough to have earned enough Social Security credits. The exact requirement depends on your age when you became disabled, but generally you need at least 20 credits earned in the 10 years before disability, and at least 40 credits total in your lifetime. One credit is earned for roughly $1,730 in wages in 2024 (the threshold changes yearly).

If you do not have enough work credits for SSDI, you may be may be able to access for Supplemental Security Income (SSI) instead. SSI is a needs-based program with no work history requirement. The maximum SSI payment in 2024 is $943 per month for an individual, though it varies by state. SSI also has strict asset limits: you can own no more than $2,000 in countable resources.

Frequently Asked Questions

Can I find out my exact SSDI payment before I file a claim?

No. Social Security will not calculate your exact payment until you file and the agency processes your claim. You can estimate it using the Benefit Estimator tool on ssa.gov, but the estimate assumes you continue working at your current pace. Once you file, Social Security will recalculate based on your actual earnings through the month you file.

Does the amount of my SSDI payment depend on how severe my disability is?

No. SSDI payments are based entirely on your earnings record. Two people with identical disabilities but different work histories will receive different payments. Social Security does not pay more for more severe disabilities.

What if I think Social Security has the wrong earnings in my record?

Request a Social Security Statement from ssa.gov or call 1-800-772-1213. The Statement shows your year-by-year earnings history. If you see errors, submit W-2s or tax returns to Social Security to correct them. Errors in your earnings record directly lower your payment.

Will my SSDI payment increase when I turn 65?

No. Your SSDI payment converts to a retirement benefit at your full retirement age, but the amount stays the same. You will receive cost-of-living adjustments (COLAs) each year, which explore to both SSDI and retirement benefits equally.

Can my family members receive benefits on my SSDI record?

Yes. Your spouse at full retirement age can receive up to 50 percent of your Primary Insurance Amount, and your unmarried children under 19 can each receive up to 75 percent. The total paid to all family members combined cannot exceed 150 to 180 percent of your Primary Insurance Amount.
