What SSDI and SSI actually pay each month
Social Security Disability Insurance (SSDI) pays based on your own work history and earnings record. The amount is calculated from your average lifetime earnings before you became disabled. In 2024, the average SSDI payment is around $1,550 per month, but individual payments range from roughly $600 to over $3,800 depending on how much you earned while working.
Supplemental Security Income (SSI) is a needs-based program with a federal maximum of $943 per month in 2024 for an individual living alone. SSI does not depend on your work history—it depends on your current income and assets. If you have other income or own more than $2,000 in countable resources, your SSI payment shrinks or disappears entirely.
The actual dollar amount you receive depends on which program you are on, how much you earned (for SSDI), what state you live in (SSI varies by state), and whether you have other income. Neither program is means-tested in the way SSI is, but both have rules about how other money affects your payment.
Key Takeaways
- SSDI payments are based on your earnings history and average around $1,550 per month, but range from $600 to $3,800 depending on how much you earned before becoming disabled.
- SSI has a federal maximum of $943 per month for individuals and does not depend on work history, only on current income and assets under $2,000.
- Your state may add money to the federal SSI amount, so the total varies by where you live.
- If you work while on either program, your payment may be reduced or suspended depending on how much you earn and which work incentive rules explore to you.
- SSDI recipients become may be able to access for Medicare after 24 months of receiving benefits; SSI recipients may be on Medicaid when ready.
How SSDI calculates your monthly payment
Social Security uses a formula based on your Primary Insurance Amount (PIA), which is derived from your average indexed monthly earnings over your highest-earning 35 years. The formula is progressive—it replaces a higher percentage of lower earnings and a lower percentage of higher earnings. This means two workers with very different salaries will not have payments that are straightforward proportional to their earnings.
You can see your own earnings record and a rough estimate of your future SSDI payment by creating an account on ssa.gov and viewing your Social Security Statement. The statement shows your estimated payment at full retirement age, at 62, and at 70—but if you are on disability now, your actual payment is calculated differently and will be shown on your award letter.
Your SSDI payment does not change based on the cost of living in your state or region. It is the same whether you live in rural Mississippi or San Francisco. However, Social Security adjusts all SSDI payments annually for cost-of-living increases (COLA), which are announced each October and take effect in January.
How SSI calculates your monthly payment
SSI starts with a federal benefit rate (FBR), which is $943 per month for an individual in 2024. From that amount, Social Security subtracts any other income you have. Earned income (from work) is reduced by $65 per month and then by 50 percent of the remainder. Unearned income (such as a pension, child support, or gifts) is subtracted dollar-for-dollar after a $20 monthly exclusion.
Many states add their own supplement to the federal SSI amount. These state supplements range from a few dollars to over $200 per month, depending on the state. If you move to a different state, your SSI payment will change. You can find your state's current SSI rate on ssa.gov or by calling your local Social Security office.
SSI also has strict asset limits. You can own no more than $2,000 in countable resources as an individual (or $3,000 as a couple). Your home, one car, and certain personal items do not count toward this limit, but bank accounts, stocks, and second vehicles do. If your assets exceed the limit, you lose SSI entirely until your resources fall back below the threshold.
What happens to your payment if you work
SSDI has work incentives that allow you to earn money without losing your entire benefit. The most common is the Trial Work Period (TWP), which lets you work and earn any amount for nine months (not necessarily consecutive) without affecting your SSDI payment. After the TWP ends, you enter the Extended may be able to access Period (EEP), during which your payment is reduced if your earnings exceed the Substantial Gainful Activity (SGA) threshold—which is $1,550 per month in 2024 for non-blind individuals.
SSI is harsher. Earned income reduces your payment by 50 cents for every dollar you earn above $65 per month. If you earn $200 per month, your SSI payment drops by $67.50. If you earn enough to push your total income above the federal benefit rate, your SSI stops entirely. However, SSI also has work incentives like the Plan to Achieve Self-Support (PASS), which lets you set aside income and resources for a specific work goal without losing benefits.
Both programs have rules about in-kind support and maintenance (food or shelter provided by someone else), which can reduce your payment. If someone else pays your rent or buys your groceries, Social Security may count that as income and lower your benefit.
Why two people on SSDI get different amounts
Two people both approved for SSDI can receive very different monthly payments because the amount is tied to their individual earnings history. Someone who worked full-time for 40 years at a high salary will have a much higher PIA than someone who worked part-time or had lower wages. A person who took time out of the workforce to raise children will have lower average earnings and thus a lower payment.
Your SSDI payment is also affected by when you became disabled. If you became disabled at 25, your 35-year average includes years of zero earnings, which lowers your PIA. If you became disabled at 55 after a long career, your average is higher. Social Security uses your highest 35 years of earnings, so early low-earning years can be dropped if you have enough higher-earning years to replace them.
Spousal and child benefits also vary. If you are on SSDI, your spouse and children may be may have access to to benefits based on your record. A spouse's payment is typically 50 percent of your PIA (reduced if they claim before full retirement age), and each child's payment is 75 percent of your PIA. However, there is a family maximum—the total paid to you and all family members cannot exceed 150 to 180 percent of your PIA.
Cost-of-living adjustments and annual changes
Every January, Social Security increases SSDI and SSI payments by a percentage tied to inflation. This is the Cost-of-Living Adjustment (COLA). In 2024, the COLA was 3.2 percent. The exact percentage changes each year based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). Social Security announces the new COLA in October, and it takes effect in January.
SSI recipients also receive the same COLA increase, but state supplements may or may not increase. Some states automatically increase their supplement by the same percentage; others do not. Check with your state's SSI program to understand how your state handles COLA for its supplement portion.
Your SSDI payment can also change if you return to work and your earnings record is updated, if you reach full retirement age (at which point your payment may be recalculated), or if you are found to no longer be disabled during a continuing disability review (CDR). SSI payments can change if your income or assets change, if you move to a different state, or if your living situation changes.
How your payment compares to other income sources
SSDI and SSI are often the only income source for people with disabilities, but they are not designed to replace a full-time salary. The average SSDI payment of $1,550 per month is below the federal poverty line for a single person. Many SSDI recipients also receive Supplemental Security Income (SSI) if their SSDI payment is very low, though this is called "concurrent benefits" and is less common than receiving one program or the other.
If you have other income—such as a pension, workers' compensation, unemployment benefits, or family support—it may affect your SSI payment but not your SSDI payment. SSDI is not income-tested, so a pension or inheritance does not reduce your SSDI check. However, if you are on SSI, any other income will reduce your SSI payment dollar-for-dollar (after the $20 exclusion for unearned income).
Some people on SSDI also receive Veterans Benefits, workers' compensation, or a state disability payment. These do not reduce your SSDI, but they may affect your Medicare or Medicaid coverage. If you receive workers' compensation and SSDI, Social Security may reduce your SSDI payment so that the total does not exceed 80 percent of your average current earnings before you became disabled.
Frequently Asked Questions
Can I find out my exact SSDI payment before I am approved?
You can get an estimate by creating a my Social Security account on ssa.gov and viewing your Social Security Statement. However, the estimate shown is for retirement benefits, not disability. Your actual SSDI payment will be calculated and shown on your award letter once Social Security approves your claim. The amount may differ from your retirement estimate because the calculation is different.
Does my SSDI payment increase if I have dependents?
Your own SSDI payment does not increase, but your spouse and children may be may have access to to separate payments based on your record. Each family member's payment is a percentage of your Primary Insurance Amount, and the total family payment cannot exceed 150 to 180 percent of your own benefit. If you have dependents, Social Security will explain their potential benefits on your award letter.
What is the difference between my SSDI payment and my Medicare premium?
Your SSDI payment is the monthly cash benefit you receive. Your Medicare premium (Part B and Part D) is deducted from that payment. In 2024, the standard Part B premium is $174.70 per month, though it varies by income. Your actual SSDI check is your payment minus any premiums and other deductions. Social Security shows the breakdown on your benefit statement.
If I move to a different state, does my SSDI payment change?
No. SSDI payments are federal and do not vary by state. However, if you are on SSI, your payment will change because most states add a supplement to the federal amount. Moving from a state with a high supplement to one with a low or no supplement can significantly reduce your total SSI payment.
Why is my SSDI payment less than the average I read about?
The average SSDI payment of around $1,550 includes people at all earnings levels. If you had lower earnings during your working years, your payment will be below average. If you became disabled early in your career, your average earnings are lower. Your payment is based on your specific earnings history, not on the national average.
