CHIP vs ACA plan
CHIP (Children's Health Insurance) and ACA Marketplace Plan solve the same problem in different ways. CHIP covers children in families with incomes above Medicaid limits but still needing affordable coverage. Benefits are comprehensive for kids and premiums are low or zero depending on the state. Parents should check both Medicaid and CHIP when a child needs coverage. By contrast, ACA Marketplace plans are comprehensive major-medical insurance that must cover the ten essential health benefits, cannot deny you or charge more for pre-existing conditions, and are the only option eligible for income-based premium tax credits. Depending on income and household size, subsidies can dramatically lower the premium — many enrollees qualify for plans at little or no monthly cost — which makes the Marketplace the default starting point for most people buying their own coverage. Below we compare them on cost, coverage, eligibility, and who each one fits best — with sources you can check.

| Typical monthly cost | Often $0-$50/mo per child (state-dependent) | Approx. $0-$600/mo after subsidies (a large share of enrollees pay under $100/mo) |
