How Much Is Health Insurance for an 18-Year-Old?

The average cost of health insurance can vary based on various factors, often reflecting circumstances such as your age, health, location and more. The type of plan you get also plays a role in rates.

When getting health insurance for the first time, different aspects of the plan can also affect the costs. For instance, health insurance plans can have varying deductibles, the amount the policyholder must pay out-of-pocket before the insurance policy covers certain expenses. Plans also offer different maximum out-of-pocket (MOOP) costs, the maximum a policyholder would have to pay for covered services in a given year.

Both the deductible and the MOOP can affect your monthly premium. Typically, the higher the deductible, the lower your monthly costs and vice versa. Since 18-year-olds have fewer medical needs, it is common for them to opt for higher deductibles.

Review the table to understand the average costs for different types of plans, with the lowest-priced options offering a higher deductible or MOOP.

Expanded Bronze
















The Bronze tier is typically the lowest and most affordable in most states, but some areas may have a Catastrophic tier for healthy 18-year-olds that meet eligibility requirements. Aside from being able to cover emergencies and preventative medicine, Catastrophic plans are also cheaper than Bronze plans but often have a higher deductible.

On average, a Catastrophic plan costs $208 per month with an $8,550 MOOP or deductible.


Understanding Health Insurance Costs vs. Healthcare Expenses

Getting the lowest coverage plan is not for everyone. While some plans may be more affordable in terms of monthly premiums, it’s important to review a health insurance policy’s annual cost vs. the expected cost of treatment.

For instance, getting a plan with a monthly premium of $1,000 is not ideal for a healthy 18-year-old as they are unlikely to need medical care that reaches those costs. If the price of potential treatment out-of-pocket is lower than the annual premium, which in this example is $12,000, then it may be better to opt for a lower-cost plan.

Conversely, an 18-year-old who frequently needs to visit the doctor or get prescriptions may benefit from a plan with a higher premium and lower deductible to get coverage sooner. It is important to weigh the costs and benefits of a health insurance plan before enrolling to make the best decision for your needs.

If you are part of your parent’s health insurance, know that coverage will not last forever. Generally, all states allow children or young adults to stay on their parent's plan until age 26. However, some states have extended the age limit beyond 26.

Types of Health Insurance for 18-Year-Olds

There are various types of health insurance plans for 18-year-olds, all of which have varying premiums, networks and benefits. Plan types include Health Maintenance Organization (HMO), Preferred Provider Organization (PPO), Point-of-Service (POS) and Exclusive Provider Organization (EPO).

These plans differ primarily in the following ways:

  • HMOs are the most common type of plan due to having low overall costs. However, they also tend to have the most restrictions in terms of networks.
  • PPO plans tend to have the most extensive networks and flexibility in accessing providers. They also generally come with a higher price tag.
  • An EPO is similar to a PPO, except it does not provide out-of-network coverage. An EPO's network size is generally similar to an HMO, minus coverage outside the network.
  • POS plan features vary widely from carrier to carrier. For example, they can sometimes require referrals and exclude out-of-network coverage and their premiums are usually higher than an HMO and lower than a PPO.

Parent’s Plan

If a parent has health insurance through an employer, their children are likely also covered. Parents can keep their children on their plan until age 26, but this limit can vary from state to state.

Employer Plan

Health insurance plans offered by employers are generally the best option for those 18 or older. In general, these plans are less expensive than individual policies and provide greater coverage.


Eligible 18-year-olds can get health insurance through Medicaid. However, Medicaid requires that applicants have a certain income level, as they only serve low-income individuals and families.


The marketplace offers a variety of plans, including those that cover prescription drugs, mental health services and preventive care.

Directly Through Providers

Medical insurance for 18-year-olds is offered by various providers. Short-term options are available and can be a good way to get started while you shop around for a plan that fits your needs.

In the past, individuals could be penalized for not having qualifying health insurance coverage and have to pay a fee. However, as of January 1, 2019, this is no longer the case. Despite this, it's essential to have some form of health insurance to help with medical care. Even a high deductible or Catastrophic plan can be better than getting stuck with enormous medical bills.

Best Health Insurance for an 18-Year-Old

When it comes to the best health insurance for 18-year-olds, there is no universal best choice. The best health insurance for an 18-year-old depends on various factors such as their profile, provider and plan type. Generally, however, most healthy 18-year-olds can opt for a low premium, high-deductible or MOOP policy, such as a Bronze tier HMO.

Below are a few examples of the best types of health insurance for 18-year-olds based on their situation.

    Unhealthy or Chronic Illness

    For individuals with chronic illnesses or who generally suffer from bad health, a plan with a higher premium and lower deductible may be best. HMO plans are suitable for individuals comfortable with a limited network, while a PPO plan may be best for those who need specialist care and often need out-of-network coverage.

Health insurance is usually an annual commitment that you can change during annual enrollment periods. It’s smart to compare plans yearly to ensure you're still getting the best deal for your needs.
