Disability benefits calculator: how much can you get in 2025?

Last updated 2026-07-09

How does Social Security actually calculate your disability benefit?

SSA ignores your medical bills, your debts, and how sick you feel. For SSDI, the number comes entirely from your earnings history. For SSI, it comes from your income and assets right now. Two programs, two different math problems. Mixing them up is the fastest way to misread what you might get.

For SSDI, SSA pulls your complete earnings record from IRS data going back to your first year of covered work. Older wages get inflated to today's dollars using national average wage indexing. Then SSA averages your highest 35 years. Work fewer than 35 years and zeros fill the empty slots, dragging the average down. That average is your Average Indexed Monthly Earnings (AIME). ^[1]

For SSI, there is no earnings formula at all. The federal benefit rate is a fixed number Congress sets each year. In 2025 that rate is $967 a month for an individual and $1,450 for a couple. Your actual payment equals that rate minus any countable income you already have. ^[2]

Which program applies to you is the whole foundation. If you have enough work credits (generally 40 total, with 20 earned in the last 10 years), SSDI is your path. If you do not, SSI is the fallback, as long as your resources stay below $2,000 for an individual.

What is the SSDI benefit formula step by step?

SSA turns your AIME into a Primary Insurance Amount (PIA) using a bent-line formula built on two bend points. The bend points shift a little each year. For 2025 the formula runs like this ^[1]:

• 90% of the first $1,226 of AIME
• 32% of AIME between $1,226 and $7,391
• 15% of AIME above $7,391

Add those three pieces and round down to the nearest dime. That is your monthly SSDI payment before any offsets.

Here is a worked example. Say your AIME is $3,000.

Tier	Calculation	Result
First $1,226 at 90%	$1,226 × 0.90	$1,103.40
$3,000 minus $1,226 = $1,774 at 32%	$1,774 × 0.32	$567.68
Nothing above $7,391	none	$0
PIA total		$1,671.08

That rounds down to $1,671.00. It is your raw monthly benefit before Medicare premiums or any reduction. The formula tilts hard toward lower earners. Someone with an AIME of $1,000 replaces about 90% of prior earnings. Someone with an AIME of $9,000 replaces closer to 33%.

One number worth knowing: SSA publishes the exact bend points for every year in its Program Operations Manual System (POMS). ^[1] The 2025 values above come from that source. Estimating a future benefit? Use the current year's bend points as a reasonable stand-in.

You can pull your own estimated SSDI amount right now. Log into my Social Security at ssa.gov and read your Social Security Statement. SSA refreshes it every year and shows a disability estimate built from your real earnings record. That is the most accurate starting point you have. ^[3]

What is the average and maximum SSDI payment in 2025?

The average SSDI payment for a disabled worker in early 2025 was about $1,580 a month, per SSA data. ^[4] That figure covers the full population of current recipients, including people who qualified years ago on older earnings records.

The maximum possible SSDI payment in 2025 is $4,018 a month. ^[4] Hitting that ceiling takes a very high earnings history sustained across decades, so most people land well below it.

See the social security disability benefits pay chart for how payments spread across income ranges.

These numbers get a cost-of-living adjustment (COLA) each year. The 2025 COLA was 2.5%, applied automatically to every benefit starting with the January 2025 payment. ^[4] SSA announces the COLA each October, so that announcement tells you next January's payment.

Family benefits can add to the household total. A spouse, a child under 18, or a child who became disabled before age 22 may each receive up to 50% of your PIA on your record. The total family benefit is capped, usually between 150% and 180% of your PIA, under SSA's family maximum formula. ^[1]

How do you estimate your SSI payment amount?

SSI math is simpler than SSDI but not obvious. Start with the 2025 federal benefit rate: $967 for an individual, $1,450 for a couple. ^[2] Then subtract your countable income.

Not all income counts. SSA excludes the first $20 of almost any monthly income, the first $65 of earned income, and then half of whatever earned income is left. That earned income exclusion is the one that matters most if you do part-time work.

Here is the math on $400 a month in wages:

Step	Amount
Total earned income	$400
Subtract $65 earned income exclusion	$335
Subtract half of remainder	$167.50
Countable earned income	$167.50
Federal benefit rate	$967
Minus countable income	$167.50
Estimated SSI payment	$799.50

Got unearned income too (say a small pension)? SSA takes the $20 general exclusion off that first, then subtracts the rest dollar for dollar from your benefit.

Many states add a State Supplemental Payment (SSP) on top of federal SSI. California, New York, and Massachusetts pay the largest supplements. California's combined SSI/SSP rate for an individual living independently in 2025 runs over $1,100. ^[5] Your state agency administers the supplement, so contact your local SSA office for the current figure where you live.

Resources also matter for SSI. You cannot receive it with more than $2,000 in countable assets ($3,000 for a couple). ^[2] The home you live in, one car, and certain retirement accounts do not count. If you are close to that line, sort out what counts as a resource before you file. It can change everything.

Does your work history affect how much SSDI you get?

Yes, directly. Every year you worked and paid FICA taxes moved your eventual SSDI number up or down. Years with zero or very low earnings pull down your 35-year average.

Gaps are common in disability cases. Plenty of people applying for SSDI are in their 40s or 50s with years of low income from episodic illness, caregiving, or part-time work. Those gaps hurt. Someone who worked steadily at $50,000 for 30 years will have a higher PIA than someone with the same total earnings spread across 35 irregular years, because the second person fills fewer zero-year slots.

To see your full earnings record, go to ssa.gov and create a my Social Security account. ^[3] Check every year. Errors show up more often than people expect, especially with self-employment income or jobs where an employer botched the W-2 filing. Spot a mistake and you can request a correction with your W-2s or tax returns as proof. Fixing a $10,000 error in your record can add real money to every monthly check.

Insured status matters too. To qualify for SSDI at all, you generally need 20 work credits from the last 10 years (40 credits total). In 2025 you earn one credit per $1,810 in earnings, up to four a year. ^[6] If you stopped working years ago because of your condition, check whether you are still insured. SSA calls this your Date Last Insured (DLI). You must be disabled on or before that date to qualify.

Are there offsets or reductions that lower your SSDI payment?

Several things can knock your SSDI check below the raw PIA.

The workers' compensation offset is the biggest one. Collect workers' comp or certain public disability benefits and SSA reduces your SSDI so the combined total stays under 80% of your pre-disability earnings. ^[7] The offset fades once your workers' comp ends.

Government Pension Offset (GPO) hit people who got a pension from a job not covered by Social Security, like some state and local government positions. On a spousal or survivor SSDI benefit, GPO could cut it by two-thirds of the government pension. ^[8]

The Windfall Elimination Provision (WEP) reduced your own SSDI or retirement benefit if you also drew a pension from non-covered work. Here is the recent change that matters: the Social Security Fairness Act, signed in January 2025, eliminated GPO and WEP entirely for affected workers. ^[8] If WEP or GPO reduced your benefit in the past, SSA is processing retroactive payments to make you whole.

Medicare Part B premiums come straight out of your SSDI payment. The standard Part B premium in 2025 is $185.00 a month. ^[9] If you are newly on Medicare after your 24-month SSDI waiting period, that amount leaves your check before you ever see it.

Taxes on SSDI are possible but not automatic. If your combined income tops $25,000 (individual) or $32,000 (married filing jointly), up to 85% of your benefit can be taxable. ^[10] See are disability benefits taxable for the full breakdown.

How accurate are online disability benefit calculators?

Honest answer: fine for a ballpark, unreliable for precision. Most third-party calculators take your stated annual income and a rough guess about your work history. They cannot see your actual Social Security earnings record, so they estimate the AIME instead of computing it.

The only truly accurate calculator is the one SSA runs, because it uses your real earnings record. SSA gives you two ways in. The Social Security Statement inside your my Social Security account shows a disability benefit estimate. ^[3] SSA's online calculators at ssa.gov also let you model different scenarios, though the detailed tool (AnyPIA) needs a software download and is built more for professionals.

Third-party calculators on financial sites help you understand the formula and roughly where you might land. Do not treat their output as your actual payment. If the number drives a financial decision, get it from my Social Security or call SSA at 1-800-772-1213.

Want to organize your claim before calling SSA or filing? DisabilityFiled runs a guided intake that collects the exact information SSA asks for and produces a structured claim summary you can use in your application. It is not a substitute for the SSA calculator, but it cuts the odds you overlook a field that changes your benefit.

For the bigger picture on your disability benefits options, including the split between SSDI and SSI, read the program overviews before you chase a number. It saves real confusion later.

How does disability pay compare to what you earned before?

SSDI never replaces your full salary. The bent-line formula pays a higher replacement rate to lower earners on purpose. At an AIME of $1,000 (roughly $12,000 a year), the replacement rate sits near 90%. At an AIME of $8,000 ($96,000 a year), it drops to around 35% to 40%.

Here is how replacement rates look across income levels, using 2025 bend points:

Prior Annual Earnings	Approximate AIME	Estimated PIA	Replacement Rate
$20,000	$1,667	$1,148	~69%
$40,000	$3,333	$1,712	~51%
$60,000	$5,000	$2,256	~45%
$80,000	$6,667	$2,729	~41%
$100,000	$8,333	$3,026	~36%

These are rough estimates using 2025 bend points and assume 35 years of steady earnings. Real results vary.

Veterans are a separate story. VA disability compensation runs on a rating system based on degree of impairment, not earnings. A 100% disabled veteran can receive over $3,737 a month from VA in 2025, and that benefit does not offset SSDI in most cases. You can collect both. ^[11] See 100 disabled veteran benefits for what stacks on top of that baseline.

Long-term disability (LTD) insurance from an employer usually pays 60% to 70% of pre-disability income. Most LTD policies carry an offset clause, though: they cut their payment dollar for dollar once SSDI starts. Your total income may stay about the same, but more of it shifts to SSA. ^[12]

When does your disability benefit start and what is the waiting period?

SSDI has a five-month waiting period. SSA pays nothing for the first five full calendar months after your established onset date. ^[1] If your onset date is February 15, your first payable month is August. Benefits start with the sixth month, and SSA pays one month in arrears, so the first real check usually lands in month seven.

Apply after your onset date and win approval for back benefits, and those cover from month six after onset up to the date SSA approved your claim. Here is the catch worth remembering: the maximum retroactive SSDI benefit reaches back 12 months before your application date, not your onset date. Delaying your application has a real dollar cost.

SSI has no waiting period. Once approved, benefits start the month after you apply or the month after you became eligible, whichever is later. ^[2]

Medicare for SSDI recipients begins 24 months after your first month of SSDI entitlement, not 24 months after approval. ^[9] That distinction matters for planning. The wait still applies even if SSA took two years to approve your claim.

See the social security disability benefits payment schedule for the dates SSA deposits payments each month based on your birth date.

Can you get a higher payment if you work while receiving disability?

SSDI does not reward extra earnings once you are on benefits, but it does protect you during a trial. SSA allows a Trial Work Period (TWP) of nine months (not necessarily in a row) within a rolling 60-month window, where you can work and earn any amount without losing your benefit. In 2025, any month you earn more than $1,110 counts as a TWP month. ^[6]

Once those nine months are used, SSA checks whether you are performing Substantial Gainful Activity (SGA). In 2025, SGA is $1,620 a month for non-blind individuals and $2,700 for blind individuals. ^[6] Earn consistently above SGA after the TWP and your benefits stop. Stay below it and they continue.

SSI works differently. Because it is need-based, every dollar you earn reshapes your benefit through the exclusions above. There is no cliff. It phases out gradually. SSA also runs a program called 1619(b) that lets you keep Medicaid even after your SSI cash benefit hits zero, as long as your earnings stay under your state's threshold. ^[2]

Either program, working while on benefits means reporting your earnings to SSA promptly. Unreported earnings create overpayments, and SSA will come back for that money, sometimes years later.

Thinking about applying? Read apply for social security disability first. Knowing the SGA limit before you file shapes how you describe your current work on the application.

What if your disability benefit amount is wrong after approval?

Mistakes happen. SSA may compute your PIA from an earnings record missing years of income, or apply an offset that should not apply. Step one: read your award letter closely. It lists your PIA, any offset amounts, your date of entitlement, and your Medicare start date. If a number looks off, move.

You have the right to request reconsideration of any SSA determination, the payment amount included. The deadline is 60 days from the date you receive the notice (SSA assumes you got it five days after the mailing date). ^[7] Miss it and your options narrow, though they do not vanish.

If the problem is an earnings record error, the fix goes through SSA's earnings correction process, not the appeals process. Pull your W-2s, tax returns, and pay stubs for the disputed years. Send them to your local SSA office with a written request. SSA can correct the record and recompute your benefit.

For complex offset situations or GPO/WEP disputes, a Social Security attorney or advocate earns their keep. Most work on contingency, capped by law at 25% of past-due benefits or $7,200, whichever is less. ^[7] They do not charge to fix your ongoing monthly amount, only for past-due benefits recovered. See long term disability lawyer if you are also running a private LTD claim alongside SSDI.

DisabilityFiled's guided intake captures everything relevant to your benefit computation, work history and any offsets included, so your claim summary is complete before you submit.

Frequently asked questions

How much is the average SSDI check in 2025?

The average SSDI payment for a disabled worker in 2025 is about $1,580 a month, per SSA data. The maximum possible payment is $4,018 a month. Your actual amount depends on your earnings history and the 35-year average SSA runs through its benefit formula. Most people land somewhere between those two figures.

How do I calculate my SSDI benefit amount?

SSA turns your Average Indexed Monthly Earnings (AIME) into a Primary Insurance Amount (PIA) using bend points. For 2025 that is 90% of the first $1,226 of AIME, 32% of AIME between $1,226 and $7,391, and 15% of anything above $7,391. Add the three amounts and round down for your monthly benefit. Your my Social Security account at ssa.gov shows the actual estimate.

What is the maximum SSI payment in 2025?

The federal SSI maximum for 2025 is $967 a month for an individual and $1,450 a month for a couple. Many states add a supplement on top. California, New York, and Massachusetts pay some of the highest combined amounts. Your actual payment equals the maximum minus your countable income, which excludes the first $20 of most income and the first $65 of earned income.

Does working affect my disability benefit amount?

For SSDI, you get a nine-month Trial Work Period where you can earn any amount without reduction. After that, earning above $1,620 a month (2025 SGA limit) can stop your benefit. For SSI, earnings reduce your benefit gradually through income exclusions. You never hit a cliff where one extra dollar wipes out everything, but SSI phases out as income rises.

How far back can SSDI pay retroactive benefits?

SSA can pay SSDI retroactively up to 12 months before your application date, as long as you were disabled during that stretch and past your five-month waiting period. It does not reach back to your actual onset date without limit. That is why filing promptly matters. A two-year delay in applying can cost you up to 12 months of back pay you were owed.

Do I get Medicare with SSDI and when does it start?

Yes, SSDI recipients automatically qualify for Medicare. It starts 24 months after your first month of SSDI entitlement, not 24 months after your approval date. That distinction can move your Medicare start date earlier if SSA approved your claim retroactively. The 2025 standard Medicare Part B premium is $185 a month, deducted from your SSDI payment.

Can I get both SSDI and SSI at the same time?

Yes, this is called concurrent benefits. It happens when your SSDI payment is low enough that your income and resources still fall below SSI limits. SSA treats your SSDI payment as unearned income for SSI, subtracts the $20 general exclusion, then pays the SSI difference. You have to meet both programs' eligibility rules at once.

How does workers' compensation affect my SSDI payment?

SSA reduces your SSDI when SSDI plus workers' compensation exceeds 80% of your average pre-disability earnings. The cut comes from the SSDI side. The offset ends when your workers' comp benefits stop, and your full SSDI PIA is restored. This is the workers' compensation offset, one of the more surprising reductions people run into after approval.

Is disability income taxable?

SSDI can be taxable. If your combined income (adjusted gross income plus nontaxable interest plus half of SSDI) tops $25,000 for individuals or $32,000 for married couples filing jointly, up to 85% of your SSDI benefit may face federal income tax. SSI is never federally taxable. State treatment of disability benefits varies widely.

Can veterans get both VA disability and SSDI?

Yes. VA disability compensation and SSDI are separate programs with separate rules. Receiving one does not reduce the other in most cases. A VA disability rating does not automatically qualify you for SSDI, and an SSDI approval does not touch your VA rating. Many veterans collect both. VA compensation runs on disability percentage; SSDI runs on your work history.

How long does it take to start receiving SSDI after applying?

Initial decisions usually take three to six months. If you are denied (about 67% of initial applications are), reconsideration adds another three to five months, and a hearing before an administrative law judge can take 12 to 24 months on top. Once approved, the five-month waiting period puts your first payable month six months after your onset date, with payment arriving about a month later.

What is Substantial Gainful Activity (SGA) in 2025?

SGA is $1,620 a month for non-blind disability applicants and recipients in 2025, and $2,700 a month for blind individuals. Earn above SGA when you apply and SSA will generally deny your claim on that basis alone, before reading your medical records. SGA applies to SSDI but not to SSI, which uses its own income-counting rules.

How do I appeal if my SSDI benefit amount seems wrong?

You have 60 days from receiving SSA's written notice to file a reconsideration request. SSA assumes you got the notice five days after mailing. If the error is in your earnings record, gather W-2s and tax returns and request a correction separately through your local SSA office. For offset or PIA disputes, an attorney experienced in Social Security can review your award letter for errors.

What happens to my disability benefit at retirement age?

When you reach full retirement age (currently 67 for those born after 1960), SSA automatically converts your SSDI benefit to a Social Security retirement benefit. The monthly amount does not change. The conversion is administrative. You do not need to apply, and your payment does not go up or down at the moment of conversion.
