SSI Benefit Calculator

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.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
