Best Family Health Insurance: Plans, Costs and Options

Medically reviewed by Jawad Arshad, MD, FACEP. Last reviewed: October 16, 2026.

Disclosure: This guide also mentions membership-based coverage. Membership-based coverage is not insurance, is not regulated as insurance, and does not count as ACA minimum essential coverage.

The best family health insurance is not one plan. It is the cheapest option that covers your whole household and your doctors, and the answer changes with your income, your employer and your state.

This guide compares the four real choices for a family, shows the 2027 subsidy cutoff with a worked example, and explains where membership-based coverage fits.

Key facts (2026):

• Employer family coverage averaged $26,993 a year in 2025, and workers paid $6,850 of it on average, about 26% (KFF, 2025 Employer Health Benefits Survey).
• Marketplace subsidies stop above 400% of the federal poverty level, which is $132,000 for a family of four for 2027 coverage (healthinsurance.org, September 2026).
• Subsidy-eligible enrollees pay between 2.15% and 10.22% of household income for the benchmark plan in 2027 (healthinsurance.org, September 2026).
• The median proposed 2027 marketplace premium increase is about 15% before subsidies (KFF, August 2026, as reported by healthinsurance.org).
• CHIP covers children in families that earn too much for Medicaid, and a family's total CHIP cost cannot exceed 5% of family income for the year (HealthCare.gov, 2026).

What is the best family health insurance?

The best family health insurance is an employer plan when your share of the premium is low, a marketplace plan when your income earns a tax credit, and CHIP or Medicaid when your children qualify. Membership-based coverage is a fourth option for some healthy families, but it is not insurance.

How much does family health insurance cost per month?

Family health insurance through an employer cost an average of $26,993 a year in 2025, or about $2,249 a month. Workers paid $6,850 of that on average, about $571 a month, and the employer paid the rest (KFF, 2025 Employer Health Benefits Survey).

Marketplace families pay the whole premium, less any tax credit. KFF reported that the median proposed 2027 increase is about 15% before subsidies, and the subsidy often absorbs much of it for subsidized buyers while unsubsidized buyers pay the full increase (KFF, August 2026, as reported by healthinsurance.org).

What is the 2027 subsidy cliff for a family of four?

The 2027 subsidy cliff for a family of four is $132,000 of household income. Above 400% of the federal poverty level, the premium tax credit is zero, and the family pays the full benchmark premium (healthinsurance.org, September 2026).

Enhanced subsidies expired after 2025. About 87% of 2026 marketplace enrollees qualified for subsidies, down from 92% in 2025 (healthinsurance.org, September 2026). For 2027, subsidy-eligible households pay between 2.15% and 10.22% of income for the benchmark plan.

Worked example: a family of four near the cliff

Assume a hypothetical benchmark plan that costs $26,400 a year for the family, or $2,200 a month. That number is made up for this example, so use your own quote.

Table: Family of four, one dollar of income can matter (hypothetical benchmark)

A $2,000 raise in this example costs the family about $13,012 in lost credit. Households near $132,000 have real options, including asking a tax professional whether anything legally lowers countable income, and some families compare membership-based coverage. Ask a licensed professional to run your exact income. Summit Health Benefits also explains the special enrollment period if your income or household changes mid-year.

Can my kids get CHIP if we earn too much for Medicaid?

Yes. CHIP, the Children's Health Insurance Program, covers children in families that earn too much for Medicaid, and each state sets its own rules (HealthCare.gov, 2026). Children can get CHIP even when the parents do not qualify for Medicaid.

HealthCare.gov says routine well-child doctor and dental visits are free under CHIP, other services may carry copayments, some states charge monthly premiums, and a family's total cost cannot exceed 5% of family income for the year. You can apply any time of year, and coverage can start immediately if you qualify (HealthCare.gov, 2026). If your children qualify for CHIP, you do not need to buy a separate plan for them, and the parents can still compare a marketplace plan.

How do I find affordable healthshare options for families?

Affordable healthshare options for families are membership-based programs where members share eligible medical costs, usually with a set out-of-pocket amount per need. They are not insurance, so they do not follow ACA rules and are not guaranteed to pay.

Summit Health Benefits offers a plan called Health Membership for Individuals and Families. Its page describes a membership for everyday care, with HealthShare for eligible major medical needs, a $2,500 out-of-pocket cap per need, and no annual or lifetime limit on eligible expenses. It lists network discounts of up to 80% on brand and specialty drugs, up to 50% on procedures and surgeries, up to 35% on specialist visits, up to 60% on lab tests and up to 75% on imaging (Summit Health Benefits, 2026). The page does not list a price, so ask for the current monthly cost before you compare. Membership is not insurance.

When is open enrollment for 2027 family coverage?

Open enrollment for 2027 marketplace coverage starts November 1, 2026 in most states and runs through January 15, 2027 in most states, with earlier or later end dates in a few (healthinsurance.org, 2026). Check your own exchange, because HealthCare.gov dates were not listed separately.

Per healthinsurance.org, Idaho runs October 15 to December 15, 2026, Massachusetts runs October 23, 2026 to January 23, 2027, Virginia ends January 29, 2027, and California, the District of Columbia, New Jersey, New York and Rhode Island end January 31, 2027. Plan start dates depend on when you pick a plan, so confirm your exchange's rule for a January 1 start before you wait.

Lock in your plan before the deadline: compare your options with a licensed professional first, then enroll on your exchange. Summit Health Benefits' open enrollment dates guide tracks the changes.

How do I compare family health insurance quotes?

Compare total yearly cost, not just the monthly premium. Add 12 months of premium to the deductible and out-of-pocket maximum you would realistically hit, then check that your doctors and prescriptions are covered.

Copy this checklist:

1. List every household member, ages, and every doctor and prescription.
2. Get your employer's family share for the year and any waiting period.
3. Get a marketplace quote for your zip code, with your estimated 2027 income.
4. Check whether any child qualifies for CHIP.
5. Add premium, deductible and out-of-pocket maximum for each option.
6. If you are near $132,000, ask a licensed professional to model the cliff.

For a quote you can act on, speak with a licensed professional through Summit Health Benefits.
