The Medicaid Eligibility Calculator determines whether an individual or family qualifies for Medicaid health coverage based on Modified Adjusted Gross Income (MAGI) thresholds that vary by state, household size, and eligibility category. Medicaid is a joint federal-state program that provides health coverage to approximately 90 million Americans, making it the largest source of health insurance in the United States. Under the Affordable Care Act (ACA), states that expanded Medicaid cover most adults with income up to 138 percent of the Federal Poverty Level (FPL), while non-expansion states use more restrictive eligibility criteria that often leave a coverage gap for adults without dependent children. Medicaid was established in 1965 as Title XIX of the Social Security Act alongside Medicare. Unlike Medicare, which is entirely federal, Medicaid is administered by individual states according to federal requirements, with each state operating its own program with its own name (such as Medi-Cal in California, MassHealth in Massachusetts, and BadgerCare in Wisconsin). The federal government matches state Medicaid spending at rates ranging from 50 percent to 77 percent based on each state's per capita income, and provides a 90 percent match for the expansion population. This federal-state partnership means that eligibility rules, covered benefits, and provider reimbursement rates vary significantly across states. Who uses this calculator? Individuals and families applying for health coverage, hospital financial counselors determining patients' likely insurance status, community health workers conducting outreach enrollment, health insurance navigators during Open Enrollment, and policy analysts evaluating coverage expansion proposals all rely on Medicaid eligibility determination. The calculator is particularly important in states that have not expanded Medicaid, where eligibility rules are complex and many low-income adults fall into a coverage gap. Medicaid eligibility determination matters because it is the gateway to comprehensive health coverage for the nation's lowest-income populations. Medicaid covers doctor visits, hospital stays, prescription drugs, mental health services, long-term care, and many other benefits with little or no cost-sharing. For children, Medicaid and the related Children's Health Insurance Program (CHIP) cover dental, vision, hearing, and developmental services through the Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) benefit. Accurate eligibility determination ensures that those who qualify receive coverage and that those who do not are directed to appropriate alternatives such as marketplace subsidies.
MAGI-based eligibility: Eligible if MAGI <= Income Threshold for Category and State. Key federal minimums (2024 FPL basis): Expansion states adults: 138% FPL. Children ages 0-1: typically 185-215% FPL. Children ages 1-5: typically 133-200% FPL. Children ages 6-18: typically 133-200% FPL. Pregnant women: 138-200%+ FPL. Parents (non-expansion): varies by state, often below 50% FPL. FPL for 2024 (contiguous 48 states): 1 person = $15,060; 2 people = $20,440; 3 people = $25,820; 4 people = $31,200. Add $5,380 per additional person. Worked example: Family of 4 in an expansion state, household MAGI = $40,000. 138% FPL for family of 4 = $31,200 x 1.38 = $43,056. Since $40,000 < $43,056, the adults qualify for Medicaid. Note: the 138% threshold includes a 5% income disregard, so the effective statutory threshold is 133% FPL.
- 1Determine the applicant's household size for MAGI purposes. The MAGI household includes the tax filer, their spouse if filing jointly, and all tax dependents. This may differ from the number of people living in the home. For example, an adult child living at home who files their own taxes is not part of their parents' MAGI household. Pregnant women count as two (the woman plus the unborn child) in some states. Household size directly affects the applicable FPL threshold.
- 2Calculate the household's Modified Adjusted Gross Income. MAGI starts with Adjusted Gross Income (AGI) from the tax return and adds back three items: tax-exempt interest income, excluded foreign earned income, and non-taxable Social Security benefits. Unlike the old Medicaid income rules, MAGI does not count assets and does not allow most income deductions or disregards (with the exception of the 5 percent FPL disregard built into the 138 percent threshold). This simplified income test was introduced by the ACA for most eligibility categories.
- 3Identify the appropriate eligibility category. Medicaid has different income thresholds for different groups: adults (in expansion states), parents and caretaker relatives, pregnant women, children (with age-based categories), aged individuals (65+), blind individuals, and disabled individuals. Each category may have a different income threshold, and some categories use non-MAGI rules (such as the aged, blind, and disabled categories, which may still consider assets). The calculator must match the applicant to the correct category.
- 4Compare the MAGI to the applicable income threshold for the state and category. In expansion states, most adults qualify at 138 percent FPL. In non-expansion states, parents may qualify at thresholds ranging from 17 percent FPL (Texas) to over 100 percent FPL, while childless adults generally do not qualify at any income level. Children and pregnant women typically have higher thresholds in all states. If income exceeds Medicaid thresholds but is below 400 percent FPL, the applicant may qualify for marketplace premium subsidies instead.
- 5Apply the 5 percent FPL income disregard for MAGI-based categories. The ACA included a 5 percent FPL disregard that is built into the commonly cited 138 percent threshold. The statutory income limit is actually 133 percent FPL, but the 5 percent disregard effectively raises it to 138 percent. This disregard applies to all MAGI-based categories, not just the adult expansion group. Understanding this distinction matters when reading statutory language versus practical income limits.
- 6Check for non-MAGI eligibility pathways if the applicant does not qualify under MAGI rules. Individuals who are aged (65+), blind, or disabled may qualify under separate Medicaid pathways that use different income and asset tests. The medically needy spend-down allows individuals with income above the Medicaid limit to qualify by incurring medical expenses that reduce their countable income to the state's medically needy level. These non-MAGI pathways are particularly important for elderly individuals needing long-term care coverage.
- 7Determine whether the state provides any additional coverage beyond federal minimums. Many states have set their Medicaid income thresholds higher than federal requirements, especially for children and pregnant women. Some states cover children up to 300 percent FPL through combined Medicaid and CHIP programs. Some states provide coverage for legal immigrants during the 5-year waiting period that federal law imposes. Others offer limited benefits for specific populations such as family planning services or breast and cervical cancer treatment.
The 138 percent FPL threshold for a single person is $15,060 x 1.38 = $20,783. With MAGI of $18,000, the applicant is well below the threshold and qualifies for full Medicaid benefits in California. As of 2024, 40 states plus DC have expanded Medicaid, covering approximately 20 million adults who would not have qualified under pre-ACA rules.
Texas has not expanded Medicaid and sets its parent income threshold at approximately 15 percent FPL. For a family of 4, 15% of $31,200 = $4,680. The parents' MAGI of $12,000 exceeds this threshold, so they do not qualify. However, their children likely qualify because children's thresholds are much higher (typically 200+ percent FPL in most states). This family falls into the coverage gap: too much income for Medicaid but too little for marketplace subsidies (which start at 100 percent FPL in non-expansion states).
All states must cover pregnant women up to at least 138 percent FPL, and most states set higher thresholds ranging from 185 to over 300 percent FPL. For a household of 2, 200 percent FPL = $40,880. With MAGI of $28,000, this woman qualifies in every state. Medicaid for pregnant women covers all prenatal care, delivery, and postpartum care for 60 days after delivery (extended to 12 months in many states under recent federal option).
Long-term care Medicaid uses non-MAGI rules that include an asset test. The asset limit is typically $2,000 for an individual (varies by state). With countable assets of $1,800 and income below the state's income cap, this individual likely qualifies. Medicaid is the primary payer for nursing home care in the United States, covering approximately 62 percent of all nursing home residents. The eligibility process for long-term care Medicaid is more complex and often involves estate planning strategies.
Hospital emergency departments and financial counselors use Medicaid eligibility screening as a critical part of the intake process. When an uninsured patient arrives at the ER, the financial counselor assesses whether the patient might qualify for Medicaid and assists with the application. Successful Medicaid enrollment retroactive to the date of application (or up to 3 months prior in most states) allows the hospital to bill Medicaid for the visit, converting uncompensated care into reimbursable care. Hospitals in expansion states have seen significant reductions in uncompensated care costs since 2014.
Community health centers and free clinics use Medicaid eligibility calculators during intake assessments to identify patients who may qualify but have not enrolled. Many eligible individuals, particularly in immigrant communities, rural areas, and populations with low health literacy, are unaware they qualify for Medicaid. Outreach workers and enrollment assistors (navigators and certified application counselors) use the calculator to screen patients during routine visits and help them complete applications on the spot, increasing coverage rates among hard-to-reach populations.
State Medicaid agencies use eligibility determination systems to process millions of applications annually. These systems automate the MAGI calculations, verify income through electronic data matching with IRS and state wage databases, and determine which eligibility category and benefit package applies. Modern eligibility systems can process straightforward MAGI-based applications in minutes, though non-MAGI cases (elderly, disabled, long-term care) often require manual review. The calculator's logic must handle hundreds of state-specific rules and exceptions.
Elder law attorneys use Medicaid eligibility planning when helping elderly clients prepare for potential long-term care needs. Nursing home costs average $9,000 to $12,000 per month, and Medicaid is the primary payer for most nursing home residents. Attorneys use the eligibility calculator to model how asset transfers, irrevocable trusts, spousal impoverishment protections, and other planning strategies affect a client's eligibility timeline. The look-back period (60 months in most states) for asset transfers adds complexity that requires careful calculation.
Pregnant women receive special treatment under Medicaid in every state.
All states must cover pregnant women with income up to at least 138 percent FPL, and most states set much higher thresholds (many at 185 to 200+ percent FPL). Medicaid coverage for pregnant women includes all prenatal care, labor and delivery, postpartum care, and treatment for conditions related to or complicated by pregnancy. Under the American Rescue Plan Act, states can now extend postpartum Medicaid coverage from 60 days to 12 months after delivery, and most states have adopted this extension.
The Medicaid spend-down (or medically needy) pathway allows individuals with
The Medicaid spend-down (or medically needy) pathway allows individuals with income above the standard Medicaid limit to qualify by deducting incurred medical expenses from their countable income. Approximately 35 states offer this pathway. The spend-down period is typically one to six months, and the individual must incur enough medical expenses during that period to reduce their income to the state's medically needy income level. Once qualified, Medicaid covers the remaining expenses for that period. This pathway is particularly important for individuals with chronic conditions who have high recurring medical costs.
Special enrollment provisions exist for individuals transitioning between coverage types.
When a person loses Medicaid eligibility (for example, due to income increasing above the threshold), they are entitled to a 60-day Special Enrollment Period to purchase marketplace coverage. States must provide advance notice of disenrollment and a fair hearing opportunity. Additionally, individuals who applied for marketplace coverage may be automatically assessed for Medicaid eligibility if their reported income falls below the threshold, and the marketplace will transfer their application to the state Medicaid agency.

What is the difference between Medicaid and Medicare?
Medicaid is a needs-based program primarily for low-income individuals and families, jointly funded by federal and state governments and administered by states. Medicare is an age-based federal program primarily for people 65 and older (and certain disabled individuals), funded by payroll taxes and premiums. They serve different populations though there is overlap: approximately 12 million people qualify for both (dual-eligible). Medicaid covers long-term care; Medicare generally does not. Medicare has standardized benefits nationwide; Medicaid varies by state.
What is the Medicaid coverage gap?
The coverage gap exists in non-expansion states where some adults have income too high for Medicaid but too low for marketplace premium subsidies (which begin at 100 percent FPL in non-expansion states). For example, a childless adult in Texas earning $10,000 per year does not qualify for Medicaid (no expansion) and does not qualify for marketplace subsidies (income is below 100 percent FPL of $15,060). An estimated 1.9 million people fall into this gap nationwide. The gap would be closed if all remaining states expanded Medicaid.
Does Medicaid count assets?
For MAGI-based eligibility categories (most adults, children, and pregnant women since the ACA), assets are not counted. Only income matters. However, for non-MAGI categories (aged, blind, and disabled individuals, and those applying for long-term care coverage), asset tests still apply. The asset limit is typically $2,000 for individuals, though some states have higher limits or have eliminated asset tests for certain groups. The home, one vehicle, household goods, and certain other assets are generally excluded.
Can legal immigrants get Medicaid?
Legal permanent residents (green card holders) face a 5-year waiting period before they can access full Medicaid benefits under federal rules. However, many states use state-only funds to provide Medicaid or Medicaid-equivalent coverage to legal immigrants during the waiting period. Pregnant women and children who are legal immigrants are eligible for Medicaid in most states without the 5-year wait under CHIPRA. Undocumented immigrants are generally not eligible for Medicaid except for emergency medical services. Some states provide state-funded coverage regardless of immigration status.
How long does Medicaid coverage last?
Medicaid coverage continues as long as the individual remains eligible. States are required to redetermine eligibility at least every 12 months. During the COVID-19 public health emergency (2020-2023), states were prohibited from disenrolling Medicaid recipients, leading to a significant increase in enrollment. After the continuous enrollment provision ended in 2023, states began unwinding their rolls and re-verifying eligibility, resulting in millions of people being disenrolled. Individuals who lose Medicaid may be eligible for marketplace coverage with premium subsidies.
What does Medicaid cover that other insurance might not?
Medicaid covers many services that are optional or limited under private insurance. Long-term care (nursing home and home-based services) is covered by Medicaid but generally not by Medicare or most private insurance. Children on Medicaid receive comprehensive EPSDT benefits including dental, vision, hearing, and developmental services. Many state Medicaid programs also cover non-emergency medical transportation, personal care services, and home health aides. Cost-sharing (copays and premiums) is minimal or nonexistent for most Medicaid beneficiaries.
Pro Tips
If your income fluctuates throughout the year (due to seasonal work, freelancing, or variable hours), apply for Medicaid using your best estimate of annual income and update the state agency when your income changes. Medicaid eligibility is typically determined on a monthly basis, so you may qualify during low-income months even if your annual average exceeds the threshold in some states. Also, always apply for coverage rather than self-determining ineligibility, because you might qualify through a pathway you are not aware of, such as the medically needy spend-down or a special state program.
Visste du?
When Medicaid was first enacted in 1965, only 4 million people were enrolled. By 2024, total enrollment exceeded 90 million, making Medicaid the single largest health insurance program in the United States. The program now covers more than 1 in 4 Americans at some point during the year. Medicaid finances approximately 42 percent of all births in the United States, covers approximately 40 percent of children, and pays for approximately 62 percent of nursing home residents. Despite covering the most vulnerable populations, Medicaid spending per enrollee is lower than private insurance spending per enrollee.
