ACA (Obamacare) Health Insurance Subsidy Calculator 2026

Calculate your estimated premium tax credit and health insurance costs under the Affordable Care Act — the marketplace coverage most people know as Obamacare.

The 2026 ACA cliff sits at 400% of the Federal Poverty Level — $84,600 for a household of two. Cross it by $1 and you lose the entire premium tax credit, typically $12,000-$25,000 per year for early retirees. OBBBA restored the cliff and eliminated the repayment cap. The calculator below shows your exact subsidy and how close you are to the cliff.

How This Works
Enter your household information to estimate your ACA subsidy (Premium Tax Credit). The calculator uses 2026 Federal Poverty Level guidelines and the ACA subsidy structure with the 400% FPL cliff. Your subsidy is based on the second-lowest-cost Silver plan (benchmark plan) in your area.

For detailed technical documentation on ACA subsidy calculations, income thresholds, and cliff optimization strategies, see the QuantCalc Methodology page.

ACA cliff threshold (400% FPL) is federal, but the dollar damage of crossing it depends on state tax. Top-tax states (worst stack-up) and no-state-tax states (cleanest math):

Each state page has the federal-state-ACA stack-up worked out with a state-specific Roth conversion example, plus the state's 30-year Monte Carlo retirement success rate (from our 51-state research).
