Obamacare (ACA) Rate Estimator
Use this calculator to estimate your potential monthly health insurance premium after subsidies (Premium Tax Credits) under the Affordable Care Act (ACA), also known as Obamacare. This tool provides an estimate based on your household income, size, and the age of the oldest member, along with a hypothetical benchmark plan cost. Actual rates and subsidies can vary based on your specific location (state and zip code), chosen plan, and other factors.
Understanding Obamacare (ACA) and Subsidies
The Affordable Care Act (ACA), often called Obamacare, is a landmark health reform law enacted in 2010. Its primary goals include making affordable health insurance available to more people, expanding the Medicaid program, and supporting innovative medical care delivery methods.
How Subsidies (Premium Tax Credits) Work
One of the most significant features of the ACA is the provision of financial assistance, known as Premium Tax Credits (PTCs) or subsidies, to help eligible individuals and families afford health insurance purchased through the Health Insurance Marketplace (also known as the exchange). These subsidies reduce the amount you have to pay each month for your health insurance premium.
The amount of your subsidy is primarily determined by:
- Household Income: Your Modified Adjusted Gross Income (MAGI) compared to the Federal Poverty Level (FPL).
- Household Size: The number of people in your tax household.
- Cost of the Benchmark Plan: This is the second-lowest cost Silver plan available in your area. Subsidies are calculated to ensure that the benchmark plan is affordable based on your income.
- Age: Older individuals generally face higher premiums, and subsidies adjust to account for this.
- Location: Premiums vary significantly by state and even by zip code due to differences in healthcare costs and competition among insurers.
The Federal Poverty Level (FPL)
The Federal Poverty Level (FPL) is a set of income thresholds used by the federal government to determine eligibility for various federal programs and benefits, including ACA subsidies. Your household income is compared to the FPL for your household size to determine your eligibility and the amount of financial assistance you qualify for. Generally, the lower your income relative to the FPL, the larger your subsidy will be.
Under the Inflation Reduction Act (IRA) of 2022, enhanced subsidies were extended, ensuring that no one pays more than 8.5% of their household income for the benchmark Silver plan, regardless of how high their income is above 400% FPL. This effectively eliminated the "subsidy cliff."
Important Considerations
- Estimates Only: This calculator provides an estimate. Your actual premium and subsidy will be determined by the Health Insurance Marketplace when you apply.
- Benchmark Plan: Subsidies are tied to the cost of the second-lowest cost Silver plan in your area. You can use your subsidy to purchase any metal-level plan (Bronze, Silver, Gold, Platinum), but if you choose a plan more expensive than the benchmark, you'll pay the difference. If you choose a cheaper plan, you'll pay less.
- Cost-Sharing Reductions (CSRs): If your income is between 100% and 250% of the FPL, you may also qualify for Cost-Sharing Reductions (CSRs) on Silver plans. CSRs lower your deductibles, copayments, and out-of-pocket maximums. This calculator does not estimate CSRs.
- Medicaid/CHIP: If your income is below 138% of the FPL in states that have expanded Medicaid, you may be eligible for Medicaid. This calculator focuses on Marketplace subsidies.
- Annual Updates: FPL numbers, benchmark plan costs, and contribution percentages are updated annually.
