The Supplemental Security Income (SSI) Calculator estimates monthly cash assistance payments for aged, blind, or disabled individuals and couples with very limited income and resources. SSI is a needs-based program funded by general tax revenues (not Social Security payroll taxes) and administered by the Social Security Administration. The federal benefit rate (FBR) for 2024 is $943 per month for an eligible individual and $1,415 per month for an eligible couple, with many states providing an additional supplement that can add hundreds of dollars to the monthly payment. SSI was established by the Social Security Amendments of 1972 and began paying benefits in January 1974, replacing a patchwork of state-administered programs for the aged, blind, and disabled. The program serves as the income floor for America's most vulnerable populations, providing cash assistance to approximately 7.5 million recipients. To qualify, an individual must be aged 65 or older, blind, or disabled (using the same medical criteria as SSDI for disability), and must have countable resources below $2,000 for individuals or $3,000 for couples. The resource limits have not been updated since 1989 and have been widely criticized as inadequate. Who uses this calculator? Social services caseworkers determining initial and ongoing eligibility, disability advocates helping clients navigate the application process, elder law attorneys planning for clients with limited means, financial planners advising families with disabled members about special needs trusts and ABLE accounts, and the beneficiaries themselves trying to understand how changes in income will affect their payment all rely on SSI benefit calculation. The income counting rules are among the most complex in any federal program, making a calculator essential for accurate estimates. The SSI calculation matters because every dollar of countable income directly reduces the SSI payment, creating a system where work, gifts, and even in-kind support can affect the monthly check. The program's income disregards ($20 general exclusion and $65 earned income exclusion, plus a 50 percent reduction in remaining earned income) create incentives for limited work but penalize income above modest levels. Understanding these mechanics is critical for beneficiaries who want to work part-time without losing their benefits and for families who want to provide financial support without inadvertently reducing their loved one's SSI payment.
SSI Payment = Federal Benefit Rate (FBR) - Countable Income. Countable Unearned Income = Gross Unearned Income - $20 general income exclusion. Countable Earned Income = (Gross Earned Income - $65 earned income exclusion) x 0.50 - any remaining $20 general exclusion if not fully used. If both earned and unearned income exist: $20 exclusion applied to unearned first, then $65 exclusion to earned, then 50% of remaining earned income. Worked example: Individual FBR = $943. Unearned income = $300/mo (SSDI), Earned income = $800/mo (part-time job). Countable unearned = $300 - $20 = $280. Countable earned = ($800 - $65) x 0.50 = $367.50. Total countable income = $280 + $367.50 = $647.50. SSI payment = $943 - $647.50 = $295.50/month.
- 1Determine categorical eligibility. The applicant must fall into one of three categories: aged (65 or older), blind (visual acuity of 20/200 or less in the better eye with correction, or a visual field limitation of 20 degrees or less), or disabled (unable to engage in substantial gainful activity due to a medically determinable physical or mental impairment expected to last at least 12 months or result in death). The disability criteria are the same as for SSDI, but SSI has no work credit requirement.
- 2Verify that countable resources are below the limit. For 2024, the resource limit is $2,000 for an individual and $3,000 for a couple. Countable resources include bank accounts, cash, stocks, bonds, and real property other than the primary residence. Excluded resources include the home and surrounding land, one vehicle (regardless of value), household goods, life insurance with face value under $1,500, burial funds up to $1,500, and property essential for self-support. ABLE accounts and certain trusts are also excluded.
- 3Calculate unearned income and apply the $20 general income exclusion. Unearned income includes Social Security benefits (including SSDI), pensions, annuities, interest, dividends, gifts, in-kind support and maintenance (food or shelter provided by others), and most other income not received from employment. The first $20 of unearned income per month is excluded. If the person has no unearned income, the $20 exclusion can be applied to earned income instead.
- 4Calculate earned income and apply the $65 earned income exclusion plus the 50 percent disregard. Earned income includes wages, self-employment income, and income from sheltered workshops. After subtracting the $65 exclusion and any unused portion of the $20 general exclusion, only half of the remaining earned income is counted. This creates a meaningful incentive to work because the beneficiary keeps more than half of each earned dollar. Additional work-related exclusions, such as impairment-related work expenses (IRWE) for disabled individuals, can further reduce countable income.
- 5Subtract total countable income from the Federal Benefit Rate to determine the SSI payment. If countable income equals or exceeds the FBR, the person is ineligible for SSI that month. If countable income is zero (or less than the exclusions), the person receives the full FBR. The payment is recalculated each month based on actual income, which means the SSI amount can fluctuate from month to month as the beneficiary's income changes.
- 6Add any applicable state supplement. Many states provide additional payments on top of the federal SSI amount. State supplements vary widely: California adds over $160 per month, New York adds approximately $87, while some states provide no supplement at all. In some states, the supplement is administered by SSA alongside the federal payment; in others, the state administers it separately. The state supplement is added after the federal calculation and may have its own income counting rules.
- 7Review ongoing eligibility requirements. SSI recipients must report changes in income, resources, living arrangements, and marital status to SSA within 10 days. Failure to report changes can result in overpayments that SSA will seek to recover, creating financial hardship. The redetermination process, where SSA reviews eligibility annually or when changes are reported, uses the same calculation to adjust the monthly payment. Understanding how changes affect the payment helps beneficiaries avoid surprises and potential overpayment debts.
With zero income, the individual receives the full federal benefit rate of $943 per month. Resources of $800 are well below the $2,000 limit. This represents the baseline SSI payment for a person with no other income source. In states with supplements, the total payment would be higher. For example, in California the total would be approximately $1,110 per month including the state supplement.
Countable unearned income = $450 - $20 = $430. SSI payment = $943 - $430 = $513. Combined with SSDI, total monthly income is $450 + $513 = $963. This is a concurrent benefits scenario where the person qualifies for both SSDI (based on work history) and SSI (because the SSDI amount is below the FBR). The SSI effectively tops up the total income to near the FBR plus the $20 exclusion.
With no unearned income, the $20 general exclusion applies to earned income. Countable earned = ($1,200 - $20 - $65) x 0.50 = $1,115 x 0.50 = $557.50. SSI = $943 - $557.50 = $385.50. Total monthly income = $1,200 + $385.50 = $1,585.50. The worker keeps all $1,200 of earnings plus $385.50 in SSI, demonstrating that the 50 percent disregard makes working financially beneficial even though the SSI payment decreases.
Couple FBR = $1,415. Countable unearned = $200 - $20 = $180. Countable earned = ($600 - $65) x 0.50 = $267.50. Total countable = $180 + $267.50 = $447.50. SSI = $1,415 - $447.50 = $967.50. Resources of $2,800 are below the couple's $3,000 limit. Combined monthly income = $200 + $600 + $967.50 = $1,767.50 for the couple.
Social services caseworkers at state and county agencies use the SSI calculator daily to determine initial eligibility and ongoing payment amounts for applicants and recipients. The income counting rules for SSI are among the most complex in any federal program, with dozens of exclusions, disregards, and special rules for different income types. A calculator that correctly applies the $20 general exclusion, $65 earned income exclusion, 50 percent disregard, and ISM valuation rules prevents errors that could result in incorrect payments and subsequent overpayment recoveries that harm vulnerable beneficiaries.
Elder law and disability attorneys use SSI calculations when establishing special needs trusts and ABLE accounts for clients. A properly structured special needs trust allows a disabled individual to benefit from inherited or donated funds without those funds counting as resources for SSI purposes. The attorney must calculate how trust distributions for non-food, non-shelter expenses will not affect the SSI payment, while distributions for food or shelter will be counted as ISM. The SSI calculator helps attorneys model different trust distribution strategies to maximize the client's total resources while preserving SSI eligibility.
Parents of adults with developmental disabilities use the SSI calculator to understand how financial gifts, informal support, and housing arrangements affect their child's benefit. A parent who allows their disabled adult child to live at home rent-free is providing ISM that reduces the SSI payment by up to one-third of the FBR. By charging a nominal rent that the child pays from their SSI, the parent can potentially reduce the ISM impact. The calculator helps families navigate these complex rules to maximize their loved one's total income while still providing support.
Policy researchers and advocacy organizations use SSI benefit calculations to illustrate the program's inadequacy and advocate for reform. The federal benefit rate of $943 per month ($11,316 per year) is below the federal poverty level for an individual ($15,060 in 2024), meaning that SSI by design provides income below the poverty line. The $2,000 resource limit, unchanged since 1989, would be approximately $5,000 if adjusted for inflation. Researchers use the calculator to model the impact of proposed changes such as increasing the FBR to the poverty level, raising the resource limit, or updating the earned income disregards.
When an SSI recipient lives in another person's household and receives food and
When an SSI recipient lives in another person's household and receives food and shelter from the householder, the SSI payment is reduced by one-third of the FBR (the Value of One-Third Reduction, or VTR). In 2024, this reduces the individual payment from $943 to approximately $629. This reduction applies automatically based on living arrangement and is one of the most significant factors affecting SSI payment amounts. Recipients who pay their pro-rata share of household expenses can avoid the VTR, but they must document their payments carefully.
SSI recipients in Medicaid-funded institutional care (nursing homes,
SSI recipients in Medicaid-funded institutional care (nursing homes, psychiatric hospitals) for a full calendar month receive a drastically reduced SSI payment of only $30 per month. This personal needs allowance is intended to cover small personal expenses while the institution provides room and board. The $30 amount has not been increased since 1988. When the resident is discharged, the full SSI payment resumes. For residents who enter and leave institutions frequently, the payment amount changes each month based on how many days were spent in the institution.
Deemed income rules apply when an SSI-eligible child lives with parents or an
Deemed income rules apply when an SSI-eligible child lives with parents or an SSI-eligible non-citizen lives with a sponsor. A portion of the parent's or sponsor's income and resources is deemed available to the SSI applicant, which can reduce or eliminate SSI eligibility. For children living with parents, the deeming calculation allocates parental income above certain thresholds (the FBR for non-SSI parents plus an allocation for each non-SSI child) to the child. This means a child with a severe disability might be ineligible for SSI simply because their parents have moderate income, even though the parents are struggling with disability-related expenses.

Can I receive both SSI and SSDI at the same time?
Yes, this is called concurrent benefits. If your SSDI benefit is below the SSI federal benefit rate, SSI can supplement the difference. For example, if your SSDI is $600 per month, SSI would add enough to bring your total near the FBR: SSDI of $600 becomes unearned income for SSI purposes, countable unearned = $600 - $20 = $580, and SSI = $943 - $580 = $363. Your total income would be $600 + $363 = $963. Concurrent beneficiaries also benefit from automatic Medicaid eligibility through SSI even if their SSDI amount does not yet qualify them for Medicare.
Why has the $2,000 resource limit not been increased since 1989?
The resource limit has not been adjusted for inflation or increased by Congress despite numerous legislative proposals. If adjusted for inflation from 1989, the limit would be approximately $5,000 in 2024 dollars. Advocacy organizations have pushed for increases, and the SSI Savings Penalty Elimination Act has been introduced to raise the limit to $10,000 for individuals and $20,000 for couples. The lack of adjustment means SSI beneficiaries are effectively prohibited from saving for emergencies, which perpetuates financial instability. The introduction of ABLE accounts in 2014 provided some relief by allowing savings up to $100,000 without affecting SSI eligibility.
Does my home count as a resource for SSI?
No. Your primary residence is excluded from the resource count regardless of its value, as long as you live in it. The surrounding land is also excluded. However, if you own a second property (such as a vacation home or rental property), it is counted as a resource at its current market value minus any outstanding mortgage. If you sell your home, the proceeds become a countable resource, but you may have a limited time to use the proceeds to purchase a new home without losing eligibility.
What is an ABLE account and how does it help SSI recipients?
An ABLE (Achieving a Better Life Experience) account is a tax-advantaged savings account available to individuals who became disabled before age 26 (increased to age 46 starting in 2026). The first $100,000 in an ABLE account is excluded from SSI resource counting. Contributions up to the annual gift tax exclusion ($18,000 in 2024) can be made by anyone. Distributions for qualified disability expenses (housing, education, health, transportation, and more) are tax-free and do not count as income for SSI. ABLE accounts allow disabled individuals to save meaningful amounts without losing SSI eligibility.
How does SSI affect Medicaid eligibility?
In most states (known as Section 1634 states), SSI eligibility automatically confers Medicaid eligibility with no separate application required. In a few states (known as 209(b) states), the state uses more restrictive Medicaid criteria than SSI, so SSI recipients must apply separately. In other states (known as SSI criteria states), the state uses SSI criteria but administers Medicaid separately. The Medicaid link is one of the most valuable aspects of SSI because it provides comprehensive health coverage including long-term care that would otherwise be unavailable to low-income disabled individuals.
전문가 팁
If you receive SSI and want to work, take full advantage of the earned income disregards. For every $2 you earn above the exclusions, your SSI payment decreases by only $1, meaning your total income always increases when you work. Additionally, ask SSA about Plan to Achieve Self-Support (PASS) plans, which allow you to set aside income and resources for a specific work goal without those amounts counting against your SSI. Also investigate impairment-related work expenses (IRWE), which can exclude disability-related costs from your earned income, further reducing the impact of work on your SSI payment.

When SSI was created in 1974, it replaced three separate state-administered programs: Old Age Assistance, Aid to the Blind, and Aid to the Permanently and Totally Disabled. The consolidation into a single federal program with uniform eligibility criteria was considered a major modernization. However, many states were already paying benefits higher than the new federal rate, which is why optional state supplements were created. The original 1974 FBR was $140 per month for an individual, which would be approximately $870 in 2024 dollars, slightly less than the actual 2024 FBR of $943.
