There are a few different ways to go about obtaining health insurance when you don't have a job. The most common way is through the marketplace, which is set up by the Affordable Care Act. You can also get health insurance through Medicaid or Medicare. If you're under 26, you may be able to stay on your parents' health insurance plan.
The cost of health insurance will vary depending on your location, age, income and family size. However, if you qualify for subsidies, the cost of your premiums will be reduced. In some cases, you may even qualify for free or low-cost coverage through Medicaid.
