Average health insurance cost by tier

Health insurance plans are separated into tiers based on the proportion of health care costs the insurance plan is expected to cover.

Silver plans fall around the middle, with moderate deductibles, copays and coinsurance. Catastrophic and Bronze plans offer the smallest amount of coverage, while Platinum plans offer the greatest.

The average rates paid for health insurance plans generally are inversely related to the amount of coverage they provide, with Platinum plans being the most expensive and Catastrophic and Bronze plans often being the cheapest. The following table shows the average rates a 40-year-old would pay for individual health insurance based on the tier. Older people would see their rates increase according to the age scale set by federal and state guidelines.

Average health insurance rates by plan type

Another distinction that can change the rates you pay is the type of network the plan uses.

Depending on whether the plan is a health maintenance organization (HMO), preferred provider organization (PPO), exclusive provider organization (EPO) or point of service (POS), access to health care providers will be managed in different ways.

HMOs tend to be the most restrictive about which doctors you can see and what you need to do to see them. This usually means that the insurers save on your cost of care and provide lower premiums.

Cost of private health insurance

Private health insurance is also called individual health insurance, or Affordable Care Act coverage. Thus, the costs provided on this page apply to the same type of coverage, regardless of the name. If you're not enrolling in a government-backed plan like Medicare or Medicaid, you’re buying private health insurance.

Nationally, the average monthly cost of private health insurance is $584 for a 40-year-old on a Silver plan.

The average cost of private health insurance varies based on several factors, including how you buy your plan. When you buy private health insurance through a state or federal exchange, you could be eligible for subsidies to help with monthly plan payments and other insurance costs.

You can also buy private health insurance directly from an insurance company through an agent or broker. These plans are sometimes called "off-exchange" policies and include Affordable Care Act plans. Off-exchange plans don’t qualify for cost-saving subsidies. Before you buy, it's a good idea to compare on- and off-exchange plans to see which option will save you money.

Factors that impact health insurance rates

For a particular health insurance plan, the cost of coverage is determined by certain factors set by law. States can limit the degree to which these factors impact your rates. For instance, some states like California and New York don't allow the cost of health insurance to differ based on tobacco use.

  • Age: The health care cost per person covered by a policy is set according to their age, with rates increasing as the individual gets older. Children through age 14 will cost a flat rate to add to a health plan, but premiums typically increase annually beginning at age 15.
  • Where you live: Health insurance companies determine the set of policies offered and the cost of coverage based on the state and county in which you live. A resident of Miami-Dade County in southern Florida, for instance, may pay lower rates for the same policy than a resident of Jackson County in the Florida panhandle.
  • Smoking/tobacco use: If you smoke, you could pay up to 50% higher rates for health insurance, though the state determines the maximum increase.
  • Number of people insured: The total cost of a health plan is set according to the number of people covered. For example, a family of three, with two adults and a child, would pay a much higher monthly health insurance premium than an individual.

As noted earlier, your tier and plan type also impact health insurance premiums.
