What it is: Created by the Affordable Care Act, the health insurance exchange is an online marketplace where consumers will be able to compare health plans offered by private insurance companies, figure out whether they're eligible for government health programs and determine whether they qualify for federal financial help to buy coverage.

Whom it's for: For the most part, the exchange will serve people who don't get affordable coverage through their jobs, not on a government plan like Medicare, Medicaid, VA or Tricare, individual or family coverage like the self-employed and students not currently on their parents health plans. Nearly 900,000 Georgians are expected to shop on the exchange.

This tool illustrates health insurance premiums and subsidies for people purchasing insurance on their own in new health insurance exchanges (or "Marketplaces") created by the Affordable Care Act (ACA). Beginning in October 2013, middle-income people under age 65, who are not eligible for coverage through their employer, Medicaid, or Medicare, can apply for tax credit subsidies available through state-based exchanges.

Georgia did not expand Medicaid, so some people may still be eligible for Medicaid, some will be eligible for subsidized coverage through Marketplaces, and others will not be eligible for subsidies.

With this calculator, you can enter different income levels, ages, and family sizes to get an estimate of your eligibility for subsidies and how much you could spend on health insurance. As premiums and eligibility requirements may vary, contact your state's Medicaid office or exchange with enrollment questions.
