TL;DR
In 2025, SSI's federal maximum is $967 a month for an individual. SSDI has no single cap. It's built from your lifetime earnings and averaged about $1,580 a month in early 2025. SSI is need-based and income-tested. SSDI is an earned insurance benefit. Most people with a work history get more from SSDI, but some collect both.
What is the basic difference in how SSI and SSDI amounts are set?
Both programs come from the Social Security Administration. They calculate your monthly check in completely different ways.
SSI, Supplemental Security Income, is a welfare-style program. The federal government sets a flat maximum each year called the Federal Benefit Rate (FBR). For 2025 that rate is $967 for an individual and $1,450 for an eligible couple [1]. Have any income? Your check drops (with some exclusions). Have too much income or too many resources, and you get nothing.
SSDI, Social Security Disability Insurance, works like a retirement benefit you collect early because of disability. SSA calculates your Average Indexed Monthly Earnings (AIME) from your entire covered earnings history, then runs a formula called the Primary Insurance Amount (PIA) to produce your monthly check. Two people with the same diagnosis can receive wildly different SSDI amounts based only on what they earned before they got sick [2].
Here's the practical result. A 25-year-old with almost no work history might qualify only for SSI at $967 or less. A 55-year-old engineer with 30 years of solid earnings might collect $2,400 from SSDI. Same disability. Completely different check.
What are the exact SSI and SSDI payment amounts in 2025?
Here are the real 2025 numbers, after the 2.5% cost-of-living adjustment (COLA) that took effect January 1, 2025 [1].
| Program | Who | Monthly Amount |
|---|---|---|
| SSI (federal only) | Individual | $967 |
| SSI (federal only) | Eligible couple | $1,450 |
| SSI (federal only) | Essential person | $484 |
| SSDI | Average new beneficiary (early 2025) | ~$1,580 |
| SSDI | Maximum possible (2025) | $4,018 |
| SSDI | Disabled widow(er) average | ~$1,100 to $1,400 |
The SSDI average of roughly $1,580 comes from SSA's own monthly statistical snapshots [3]. The $4,018 maximum applies only to someone who earned at or above the Social Security wage base for 35 years or more, which is rare.
State supplements can push SSI above the federal figure. California, New York, and several other states add their own money on top. California's combined maximum for an individual living independently ran over $1,100 a month in 2025 [4]. Alaska and some other states add smaller amounts. Roughly a dozen states add nothing.
So when someone asks how much SSI pays, the honest answer is: at least $967 federally, possibly more depending on your state.
How does SSA calculate your SSDI payment amount?
The SSDI formula has three steps. Once you see them, you understand why two people with similar disabilities can get very different checks.
Step 1: SSA pulls your earnings record, adjusts each year's wages for wage inflation, then averages your highest 35 years. That gives you your AIME, Average Indexed Monthly Earnings.
Step 2: SSA runs the PIA bend-point formula. For 2025 it's 90% of the first $1,226 of AIME, plus 32% of AIME between $1,226 and $7,391, plus 15% of any AIME above $7,391 [2]. The structure replaces a bigger share of a low earner's wages and a smaller share of a high earner's.
Step 3: The result is your PIA, which becomes your monthly SSDI benefit (rounded down to the nearest dime).
Run the numbers on an AIME of $3,000: 90% x $1,226 = $1,103.40, plus 32% x ($3,000 minus $1,226) = $567.68. Total PIA is about $1,671 a month before any Medicare premium comes out.
Standard SSDI has no reduction for claiming "early." The early-claiming math only shows up in a different way for disabled widow(er)'s benefits.
Create an account at ssa.gov/myaccount and pull your Social Security Statement [5]. Do this before anything else. That estimate uses your actual earnings record, which beats any calculator you'll find online.
How does income reduce your SSI payment?
SSI has an income-counting formula that trips almost everyone up at first. SSA's own rules make it less harsh than it looks.
SSA ignores the first $20 of most income per month (the general exclusion). Then it ignores the first $65 of earned income (wages). After those exclusions, SSA cuts $1 from your SSI for every $2 you earn from work. Unearned income (a pension, a gift, another disability check) gets a straight $1-for-$1 reduction after the $20 exclusion [6].
Get $400 a month in unearned income? Subtract $20, leaving $380 countable. Your SSI drops from $967 to $587.
Earn $500 in wages? Subtract the $65 earned exclusion, leaving $435, then divide by 2 for $217.50 countable. SSI drops to $749.50.
The resource limit is separate. SSI cuts off completely if you hold more than $2,000 in countable resources as an individual or $3,000 as a couple [6]. That limit hasn't moved since 1989 and has no inflation adjustment. It's why so many people lose eligibility without meaning to.
SSDI has no income test after approval, as long as you stay under Substantial Gainful Activity limits while working. For anyone with savings or a little part-time income, that's one of SSDI's real advantages over SSI.
What were SSI and SSDI amounts in prior years, including 2017?
People searching "ssdi vs ssi amount 2017" usually want to see how benefits have grown or to check a past figure. Here's the history.
| Year | SSI Individual FBR | SSDI Average Benefit | COLA Applied |
|---|---|---|---|
| 2017 | $735 | ~$1,171 | 0.3% |
| 2018 | $750 | ~$1,197 | 2.0% |
| 2019 | $771 | ~$1,234 | 2.8% |
| 2020 | $783 | ~$1,258 | 1.6% |
| 2021 | $794 | ~$1,277 | 1.3% |
| 2022 | $841 | ~$1,358 | 5.9% |
| 2023 | $914 | ~$1,483 | 8.7% |
| 2024 | $943 | ~$1,537 | 3.2% |
| 2025 | $967 | ~$1,580 | 2.5% |
Sources: SSA COLA history page and SSA statistical snapshots [1][3][10]. The SSDI averages are approximate because they shift monthly as people enter and leave the rolls.
The 2023 COLA of 8.7% was the largest in 40 years, pushed up by post-pandemic inflation [10]. If you've been on SSI since 2017, your check grew from $735 to $967, a 31.6% jump over eight years. That sounds like a lot in raw dollars. In real purchasing power it's roughly flat, given the inflation of 2021 through 2023.
For SSI amounts going back to 1975, SSA publishes an annual Statistical Supplement that anyone can read [7].
Can you get both SSI and SSDI at the same time?
Yes. It's called concurrent benefits. It happens when you qualify for SSDI but your SSDI check is small enough that you also fall under SSI's income and resource limits.
The common version: someone with a thin work history gets approved for SSDI, but the monthly benefit is only $600. The SSI FBR is $967. After SSA counts the SSDI as unearned income (minus the $20 exclusion), that person has $580 in countable income, so SSI covers the gap: $967 minus $580 is $387 in SSI. Total monthly income: $987 [6].
Concurrent beneficiaries usually get Medicaid through SSI (often right at SSI approval) and Medicare through SSDI (after a 24-month waiting period). For people with high medical costs, that dual coverage matters a lot.
About 17% of disability beneficiaries are concurrent, per SSA data [3]. If you're applying and your expected SSDI is below the SSI FBR, file for both. SSA is supposed to screen for SSI automatically, but people slip through. Ask for both by name.
For the differences beyond the dollar amounts, see our article on SSDI vs SSI: What's the Difference and Which Do You Qualify For?.
How do state SSI supplements change your monthly amount?
The federal SSI payment is the floor, not the ceiling. Many states stack their own money on top.
States that run their own supplements set their own amounts. California's State Supplementary Payment (SSP) has long been the highest in the country. New York, Pennsylvania, Massachusetts, and others add meaningful amounts too. Some states pay a supplement only for certain living arrangements, like board-and-care facilities, rather than for everyone.
Other states let SSA hand out the supplement on their behalf, which keeps the paperwork simpler. A handful of states, including Texas, Arizona, and Mississippi, add nothing at all [4].
Here's the practical advice. If your state has a supplement, your actual SSI check runs higher than the federal $967. Call your local SSA office or your state's social services agency and ask for the exact combined amount for your situation. Living arrangement changes the math. Whether you pay your own rent and food, live with family, or stay in a care facility all affect the supplement and sometimes the federal portion too.
Does receiving SSDI affect how much SSI you can get?
Yes. SSA counts your SSDI payment as unearned income when it figures your SSI. Every dollar of SSDI above $20 cuts your SSI dollar-for-dollar.
Here's the math laid out plainly:
- Your SSDI: $700/month
- Minus $20 general income exclusion: $680 countable
- SSI FBR: $967
- SSI payment: $967 minus $680 = $287
- Total income: $987
Once your SSDI hits $987 (the FBR plus the $20 exclusion), your SSI drops to zero. At that point SSDI fully covers what SSI would have.
One thing does not change. If you still qualify for SSI, even at $1, you usually keep your Medicaid. That Medicaid tie is often worth more to people than the small SSI check itself, especially in states that never expanded Medicaid under the ACA. A tiny SSI payment can be worth protecting for that reason alone.
For how SSDI payments get timed and deposited, see our guide on SSI SSDI debit cards and direct deposit.
Is SSDI or SSI taxable?
They're taxed very differently, and the difference can change which program is worth more to you after taxes.
SSI is never taxable. No federal income tax, no state income tax anywhere in the country [8]. Period.
SSDI can be taxed at the federal level if your combined income (SSDI plus other income) crosses certain lines. For a single filer, up to 50% of SSDI is taxable if combined income lands between $25,000 and $34,000. Up to 85% is taxable above $34,000 [8]. The IRS defines "combined income" as your adjusted gross income plus nontaxable interest plus half of your SSDI.
Most SSDI recipients with no other income pay no federal tax at all, because their income sits below the threshold. Add a working spouse, a pension, or rental income, and you could owe tax on part of your SSDI.
State rules vary. Some states tax SSDI the way the federal government does. Others exempt it entirely. A few tax Social Security retirement and disability above certain thresholds. Check your state revenue department.
For the full breakdown, read our piece on whether SSDI is taxable.
What reduces or stops your disability payments?
Several things can cut or end your check. Knowing them ahead of time saves you from nasty surprises.
For SSDI:
Earning above the Substantial Gainful Activity (SGA) threshold is the main trigger. In 2025, SGA is $1,620 a month for non-blind individuals and $2,700 for blind individuals [9]. If you earn more than SGA after your Trial Work Period ends, SSA can stop your SSDI. The Social Security Disability 5-Year Rule ties in here too. See our article on the 5-year rule for how reinstatement works.
Expedited Reinstatement lets you restart SSDI within 5 years of benefits stopping due to work, with no full new application [9].
For SSI:
Any jump in income or resources above the limits stops your check. Getting married can change your payment, because SSA may count your spouse's income and resources. Moving to a state with no supplement drops that portion. Going into a hospital or institution for more than 30 days cuts SSI to $30 a month.
For both programs:
Continuing Disability Reviews (CDRs) can end benefits if SSA decides your condition improved enough that you're no longer disabled. Most people with severe, permanent conditions pass CDRs without trouble, but you have to answer them. Ignore a CDR notice and your benefits almost always stop.
Which program pays more: SSI or SSDI?
For most people with any real work history, SSDI pays more. The average SSDI benefit in early 2025 was around $1,580, against SSI's $967 maximum [1][3]. Someone who worked a median-wage job for 20-plus years usually lands between $1,300 and $1,900 on SSDI.
But for people with little or no work history, SSDI can pay a few hundred dollars or nothing. Think of someone who became disabled young, or who spent years as an unpaid caregiver. In those cases SSI's $967 (or more with a state supplement) is the better floor.
So be honest with yourself: SSDI isn't always more. It rides entirely on your earnings record. The SSA statement tool at ssa.gov/myaccount shows your specific SSDI estimate, and that's the only reliable way to compare [5].
If you're trying to decide which program to lead with in your application, DisabilityFiled's guided intake walks through your earnings history and living situation so you understand both before you submit anything official.
One factor people overlook: SSDI brings Medicare after 24 months, while SSI brings Medicaid right away in most states. For someone with heavy prescription or specialist costs, the type of insurance can matter as much as the dollar figure.

How do you find out your specific benefit amount before applying?
Three practical ways get you a real number before you commit to an application.
First, create a my Social Security account at ssa.gov/myaccount [5]. Your Social Security Statement shows a disability estimate built from your actual earnings record, updated once a year. That's the most accurate preview you can get without filing.
Second, call SSA at 1-800-772-1213. A representative can give an unofficial SSDI estimate off your record. SSI is harder to estimate by phone, because it hinges on your living situation, income, and resources at the time you apply.
Third, use SSA's benefit calculators at ssa.gov. The Detailed Calculator and the AnyPIA program (downloadable from SSA's site) let you run different earnings scenarios. These are the same tools SSA uses internally [2].
SSI is simpler in concept: start at $967 (or your state's combined maximum), then subtract countable income the way we walked through above. If your only income will be SSI plus maybe a little work, you can estimate it yourself with decent accuracy.
Don't let a fuzzy dollar figure stop you from applying. You can withdraw an application within 12 months if you change your mind, and knowing the real number is worth the time it takes to check.
Frequently asked questions
What is the maximum SSI payment for 2025?
The federal SSI maximum for 2025 is $967 a month for an individual and $1,450 for an eligible couple. Those figures rose from $943 and $1,415 after the 2.5% COLA on January 1, 2025. Your state may add a supplement on top of the federal amount, so the real maximum depends on where you live.
What is the average SSDI payment in 2025?
The average SSDI payment for all disabled workers ran about $1,580 a month in early 2025, based on SSA's monthly statistical data. The exact figure moves month to month as new beneficiaries arrive and others age into retirement. Your own amount depends entirely on your earnings history and is unique to your record.
Can you get both SSI and SSDI at the same time?
Yes. It's called concurrent benefits. It happens when your SSDI check is low enough that you still qualify for SSI after SSA counts the SSDI as income. About 17% of disability beneficiaries get both. Even a tiny SSI payment can be worth keeping, because it usually preserves Medicaid while SSDI brings Medicare after 24 months.
How much was SSI in 2017?
The SSI Federal Benefit Rate in 2017 was $735 a month for an individual and $1,103 for an eligible couple. The COLA that year was only 0.3%, one of the smallest in the program's history. For comparison, the 2025 individual rate of $967 reflects a 31.6% cumulative increase since 2017.
Does SSI or SSDI pay more for a family?
SSDI can pay auxiliary benefits to your spouse and dependent children. SSI cannot. A spouse under 62 caring for your minor child can get up to 50% of your PIA, and children can get up to 50% each. There's a family maximum, usually 150% to 188% of the worker's PIA. SSI has a couple rate but no dependent benefits.
Does getting married affect my SSI or SSDI payment?
For SSDI, marriage has no direct effect on your own benefit. For SSI, marriage can cut or end your check, because SSA counts part of your spouse's income and resources as available to you, a rule called deeming. The SSI couple rate is $1,450, not double the individual rate, so two SSI recipients who marry see their combined benefit drop from $1,934 to $1,450.
How long does it take to receive your first SSI or SSDI payment?
SSI can pay from the month after your application if you're approved, with no waiting period. SSDI has a mandatory five-month waiting period: your first payment covers the sixth full month of disability. So even if SSA approves you fast, you won't see an SSDI check for at least six months from your established onset date.
What is the SSDI maximum payment for 2025?
The theoretical SSDI maximum for 2025 is $4,018 a month. It applies only to someone who earned at or above the Social Security taxable wage base for 35 years or more. Most recipients get far less. The average sits around $1,580. Your personalized estimate is available through your my Social Security account at ssa.gov.
Do SSI and SSDI amounts increase each year?
Both programs get the same annual COLA, tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). SSA announces the COLA each October for the following January. Some years had a 0% COLA (2010, 2011, 2016). The largest recent one was 8.7% in 2023. The formula is automatic; neither Congress nor the President sets it directly.
Can working part-time reduce my SSI payment?
Yes, but by less than a dollar for every dollar. SSA ignores the first $65 of earned income per month, then counts half of what's left. Earn $200 from part-time work, and SSA counts $67.50, so your SSI drops by that much. Some work-related expenses for disabled individuals can be excluded too, which softens the hit further.
Why might someone with the same disability get different SSDI amounts?
SSDI comes from your personal earnings record, not your diagnosis or how severe your disability is. Two people with identical conditions can get completely different checks if one worked a high-wage job for 30 years and the other worked part-time. The disability decision (yes or no) uses the same process for everyone, but the dollar amount is purely earnings-based.
Will my SSDI convert to retirement benefits, and will the amount change?
Yes. When you reach full retirement age (currently 67 for people born in 1960 or later), SSA automatically converts your SSDI to a retirement benefit. The dollar amount stays the same. There's no reduction or bump at conversion. The change is administrative: your benefit comes from the retirement fund instead of the disability trust fund.
Is there a resource limit for SSDI like there is for SSI?
No. SSDI has no resource or asset limit. You could have a million dollars in savings and still collect SSDI if you're medically disabled and meet the work credit requirements. SSI cuts off if you hold more than $2,000 in countable resources as an individual. This gap is one of the most important practical differences between the two programs.
How do I appeal if I think my SSDI payment amount is wrong?
You can request reconsideration of your benefit amount within 60 days of your award notice. If you suspect an error in your earnings record, start by reviewing your Social Security Statement at ssa.gov/myaccount. Wrong wage entries are fixable, and correcting them can raise your PIA. Bring W-2s or tax returns as backup to any SSA office meeting.
