Your SSDI payment amount is based entirely on your work history—your lifetime earnings before your disability began—not on the severity of your condition or your current income. Social Security Disability Insurance (SSDI) is a federal program that replaces a portion of your wages if you can no longer work due to a medical condition. In 2026, the average monthly SSDI benefit is $1,630, but your individual amount could be higher or lower depending on your earnings record.

To help you skip the math, this page includes an interactive SSDI calculator: Just enter your birth year and average recent income, and you'll get an instant estimate of your potential monthly benefit. Read on to understand how Social Security calculates that number—including the weighted formula it uses, what average payments look like across income levels and states, and what factors could reduce or change your monthly disability check.

What Is the Average Disability Payment in 2026?

How much is SSDI per month? The average SSDI payment in 2026 for an individual is $1,630, but almost two-thirds of SSDI recipients receive less than that. And only 10% of SSDI recipients receive a disability check for $2,000 per month or more.

Most SSDI recipients received between $1,000 and $1,500 per month in December 2025, as you can see from the Social Security disability benefits pay chart above. But keep in mind that, if you're receiving disability payments from other sources, your payment may be reduced (as discussed below).

If you have a family, your household SSDI income might be higher. (Minor children can get benefits, as can spouses who are taking care of minor children or who have reached retirement age.) The 2026 average Social Security check per month for an SSDI recipient who has a spouse and children is $2,937.

Estimate Your Monthly SSDI Payment: Social Security Disability Calculator

Our Social Security disability calculator estimates your disability benefit for 2026 after you enter the year you were born and your average earnings over the last ten years. The disability calculator applies the same formulas that the Social Security Administration (SSA) uses to estimate your monthly disability benefit.

Our Social Security disability calculator will give you a good estimate of your benefits, but the exact amount you'll receive depends on the following:

• your average income over your entire lifetime (up to 35 years if you've worked that long)
• whether you paid self-employment taxes if you owned your own business or freelanced
• whether you worked in any jobs that didn't pay into the Social Security system (such as state or local government jobs), and
• whether you took any years off work for child-rearing or long-term illness.

The SSDI calculator assumes you've had gradual increases in earnings over your lifetime, so if your income has fluctuated, the calculator may give you a less accurate estimate. For the exact SSDI amount you’d get if you were awarded benefits this year, you can check your Social Security Statement. Your statement also shows what your Social Security retirement benefit would be at ages 62, 67, and 70. You can also check your entire covered earnings history on your Social Security Statement.

Find your statement online at www.ssa.gov/myaccount. (If you're 60 or older, Social Security will send you a printed statement once a year if you don't set up an online account.) Setting up an account requires you to have an account with LOGIN.GOV or ID.me, two services that require ID verification and facial recognition, which requires a camera.

If you’d rather not go through the verification process, you can use Social Security’s benefits calculator without logging in, but it requires you to enter your past earnings for up to 35 years.

You can also call your local Social Security office, and a field representative will be able to give you an exact estimate of what your benefits would be.

How Does Social Security Calculate Your SSDI Benefits?

Social Security uses a complex weighted formula based on lifetime earnings to calculate benefits for each person.

Doing the math yourself to calculate your own benefit amount is difficult, but here's how the formula works. It can help to know how disability is calculated, if you don’t mind a few figures.

How Social Security’s Bend Point Formula Works

Based on Social Security's bend-point calculations for 2026, the maximum SSDI benefit for an individual with very high earnings works out to about $4,150 per month.

Social Security Disability Benefit for Age 55: Examples

Because benefit amounts depend on lifetime earnings, there's a large range in how much Social Security pays. For instance, let's look at age 55, the most common age at which disabilities start. For 55-year-olds who have worked their entire lives, Social Security typically pays $1,200 to $3,500 per month.

The benefits pay chart here shows you the ranges based on income at age 55.

Can Other Income Reduce Your SSDI Payment?

Most types of income do not reduce your SSDI payment. Income from work, private long-term disability (LTD) insurance, Supplemental Security Income (SSI), and VA benefits all leave your SSDI amount untouched. The exception is government-regulated disability benefits such as workers' compensation or temporary state disability benefits, which can reduce your monthly SSDI check.

Here's how that works: If the amount you receive in SSDI plus the amount from government-regulated disability benefits is more than 80% of the amount you earned before you became disabled, the SSDI or other benefits will be reduced.

The following types of government benefits could also lower your SSDI payment:

• workers' comp payments
• state short-term disability payments
• civil service disability benefits, and
• state or local government retirement benefits based on disability.

Can the Amount of Your SSDI Check Change Over Time?

Most years, your monthly SSDI payment will go up, thanks to Social Security's annual cost-of-living adjustment (COLA). You can find the annual COLA here.

Once you're eligible for Medicare benefits (two years after you become entitled to SSDI benefits), the cost of Medicare Part B will be taken directly out of your Social Security check. Most people will pay a premium of $202.90 for Part B in 2026, but the amount can be quite a bit higher for those with high household income. (Fact Sheet: 2026 Medicare Costs.)

If you have low income, a Medicare Savings Program can pay your Part B premium.

Otherwise, your SSDI check won't change, unless you start collecting workers' comp or one of the government benefits mentioned above.

How Much in Social Security Back Pay Can You Get?

How much you'll receive in Social Security disability back payments depends on your SSDI monthly amount. And how many months of back payments you get is determined by your application date and your established date of onset (when your disability started). For instance, if you were disabled for nine months before you were approved for benefits, you'll get four months of back pay (you have to subtract the five-month waiting period).

If you previously applied for disability benefits but didn't get them that time, your back pay might go back even further—to your original application date. Learn more about how SSDI back pay is calculated.

Average SSDI Payment by State for 2026

In most states, the average disability payment hovers around $1,550, but in a handful of states, some of them in the Midwest and northern New England, the average disability amounts dip below $1,500. This reflects the fact that SSDI payments are based on lifetime earnings, so states with historically lower wages produce lower SSDI benefits. In a few East Coast states, where wages are high (including Delaware and New Jersey), average monthly payment amounts top $1,700.

The chart below shows the average monthly SSDI payment in each state for people who can no longer work (benefit amounts for widows and adult children tend to be lower and are not included).

How to Apply for Disability Benefits

Knowing how SSDI benefits are calculated—based on your work history and earnings—helps you know what to expect if you're unable to work and are considering applying for SSDI. If you're ready, you can get help with your application by reading our article on filing an application for disability benefits. You can file online through the SSA website or in person at your local Social Security office.

Before you begin, gather the documents you'll need, including your work history for the past five years, detailed medical records from all treating physicians, information about any medical tests you've undergone, and a list of medications and dosages. Don't hesitate to apply if you can't work, because the time required to receive a decision on a disability claim can be lengthy, and your medical condition could worsen by then.

If you think you'll need help with the application, think about talking to a Social Security disability lawyer. A disability lawyer can tell you how strong your case is, help you gather the right medical documents and opinions, and handle communications with the SSA. Learn more about how Social Security disability lawyers handle claims.

If you've already been denied—and about two-thirds of initial SSDI applications are—an experienced disability attorney can help you through the appeals process. You'll only owe attorneys' fees if you win your case, and they’re capped at 25% of your back pay (no more than $9,200). Find out what to do if you’re denied benefits.
