About the Health Insurance Cost Calculator
This free health insurance cost calculator helps people in the United States get a quick, private estimate before they talk to a lender, insurer, employer or advisor. There is no signup, nothing is stored on our servers and every result updates instantly in your browser.
How this calculator works
The estimate starts from a base monthly premium that rises with age (roughly $9 more per month for every year above 25), then multiplies it by a state cost factor and by family size. Income-based subsidy tiers then reduce the figure for lower-income households, mirroring how ACA marketplace tax credits work in principle.
Worked example
A 35-year-old individual in an average-cost state earning $60,000 sees an estimated base premium of about $340 per month before subsidies. Change any input above to see how the result moves, which is the fastest way to understand which factor matters most for you.
Tips to get a better result
Compare bronze, silver and gold plans on total yearly cost (premium plus deductible plus out-of-pocket maximum), not only the monthly premium. Check whether your doctors are in-network and whether you qualify for a Health Savings Account.
Key factors that change your result
Age, location, plan tier (bronze to platinum) and household size set the premium. Income can qualify you for ACA subsidies. A cheaper premium usually means a higher deductible, so compare total yearly cost, not just the monthly price.
