The average SSDI payment in 2024 is around $1,550 per month, and the average SSI payment is around $943 per month, but your actual check depends on your work history, age, and which program you receive.

Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) are two separate programs with different payment structures. SSDI is based on what you paid into Social Security through payroll taxes — the more you earned and the longer you worked, the higher your payment. SSI is a needs-based program with a federal maximum of $943 per month in 2024, though some states add extra money on top.

These are national averages. Your actual payment could be higher or lower depending on your specific situation. The Social Security Administration (SSA) calculates each payment individually based on your earnings record, age when you started receiving benefits, and whether you have dependents who also receive payments on your account.

Key Takeaways

  • SSDI payments are based on your lifetime earnings record, so someone who worked steadily at higher wages will receive more than someone with gaps in employment or lower earnings.
  • SSI payments are capped at a federal maximum, but some states supplement this amount, so your total SSI check varies by where you live.
  • If you have a spouse or children who may have access to as dependents on your account, they may receive their own payments, which does not reduce your check.
  • Your payment amount is set when your claim is approved and increases once per year based on the cost-of-living adjustment (COLA), which the SSA announces in October for the following year.

How SSDI payment amounts are calculated

The SSA uses a formula based on your Primary Insurance Amount (PIA), which is derived from your 35 highest-earning years. If you have fewer than 35 years of earnings, zeros are counted for the missing years, which lowers your average. The SSA adjusts these historical earnings to account for wage growth over time, then calculates your monthly benefit.

If you started receiving SSDI before your full retirement age, your payment is reduced by a percentage. For example, if you were approved at age 55, your payment would be lower than if you had waited until age 60 or 62. The exact reduction depends on how many months before your full retirement age you began receiving benefits.

Your payment also increases if you have dependents — a spouse age 62 or older, or children under 19 (or 19 if still in high school) — who are may have access to to benefits on your record. Each dependent receives up to 50 percent of your PIA, though family benefits are capped at 150 to 180 percent of your PIA depending on your situation.

How SSI payment amounts are set

SSI uses a flat federal maximum rather than an earnings-based formula. In 2024, the federal maximum is $943 per month for an individual and $1,415 for a couple. However, your actual SSI payment is reduced dollar-for-dollar by other income you receive — wages, pensions, unemployment benefits, or other sources. If you have countable income above the limit, you may receive a reduced payment or no payment at all.

Nineteen states and Washington, D.C. add their own state supplement to the federal SSI amount. These supplements range from a few dollars per month to over $100, depending on the state. If you move to a different state, your SSI payment may change. You can find your state's current supplement amount on the SSA website or by calling your local Social Security office.

SSI also counts your assets — money in the bank, vehicles, property — toward a resource limit of $2,000 for an individual or $3,000 for a couple. If your resources exceed this limit, you are not paid that month, though the limit does not include your home, one vehicle, or certain other excluded items.

Cost-of-living adjustments and annual increases

Both SSDI and SSI payments increase once per year through a cost-of-living adjustment (COLA). The SSA calculates the COLA based on inflation data from the Consumer Price Index and announces the new percentage in October, effective the following January. In recent years, COLA increases have ranged from 0 percent to over 8 percent, depending on inflation.

The COLA applies automatically to all beneficiaries — you do not need to request it or do anything to receive it. Your new payment amount appears in your January check. If you are receiving both SSDI and SSI, both payments increase by the same percentage.

Factors that change your payment amount

Your SSDI payment can increase if you return to work and earn more in a year than you did in previous years, because the SSA recalculates your PIA using your updated earnings record. However, if you are still within the first 12 months of your approval, you may be in a trial work period where you can earn up to a certain amount without losing benefits.

Your payment can decrease if you reach full retirement age and choose to continue receiving SSDI, because your benefit converts to a retirement benefit at that point. The amount usually stays the same, but the program name changes and the rules around work and earnings change.

For SSI, your payment decreases if your countable income increases or if your resources exceed the limit. It also decreases if you move in with someone else who provides food or shelter, because the SSA counts this as "in-kind support and maintenance" and reduces your payment by up to one-third of the federal maximum.

What to expect when you receive your first check

Your first SSDI or SSI payment arrives one to two months after your claim is approved. The SSA sends the payment by direct deposit to your bank account or, if you do not have a bank account, to a debit card issued by the SSA. You can set up or change your direct deposit information through your my Social Security account online or by calling the SSA.

Your payment stub, called a benefit verification letter, shows your monthly amount, any deductions (such as taxes withheld or overpayments being repaid), and your year-to-date total. You can view this letter in your my Social Security account or request a paper copy by mail.

Frequently Asked Questions

Why is my SSDI payment lower than the average?

Your payment is based on your specific earnings record, not the national average. If you had lower wages, gaps in employment, or started receiving benefits before full retirement age, your payment will be lower than the average. You can view your earnings record in your my Social Security account to see how the SSA calculated your amount.

Can I get more money if I wait to start receiving SSDI?

Yes. If you wait until full retirement age or later to start receiving SSDI, your payment will be higher than if you start earlier. However, you must meet the medical criteria for disability at the time you file — you cannot straightforward wait for a higher payment without an active disability.

Does my spouse's income affect my SSI payment?

Yes. For SSI, the SSA counts your spouse's income and resources as available to you, even if they do not give you the money. This is called "deeming." For SSDI, your spouse's income does not affect your payment, but if your spouse also receives benefits, their payment is calculated separately.

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

For SSDI, you have a trial work period where you can earn up to a certain amount without losing benefits. After that, your benefits stop if your earnings exceed the substantial gainful activity limit, which is $1,550 per month in 2024 (higher for blind beneficiaries). For SSI, your payment is reduced dollar-for-dollar by wages above $65 per month, plus half of remaining earnings.

Will my payment increase next year?

Yes, assuming there is a COLA increase announced in October. The increase applies automatically to your January payment. You can check the SSA website in October to see what percentage increase has been announced for the following year.
