Health Insurance for a Family of Four in 2027: What Does It Cost?
Health insurance for a family of four costs an average of $28,303 for job-based coverage in 2026, with the worker covering $7,471 of it, while a family buying on the ACA Marketplace in 2027 can pay anywhere from under $200 to more than $2,000 a month depending almost entirely on household income.
Premiums are rising for a second straight year, and the enhanced subsidies that softened the blow for millions of households expired at the end of 2025. This guide to health insurance for a family of four shows the real numbers for both paths, a worked example at every major income level, and the moves that can keep a family on the right side of the subsidy cliff.
How much does employer health insurance for a family of four cost?
Most families of four get coverage through a job, so that is the right starting point. KFF’s 2026 Employer Health Benefits Survey found the average annual premium for family coverage reached $28,303 in 2026, up 5% from 2025. Workers paid an average of $7,471 toward that, about $623 a month, and employers paid the remaining $20,832. The worker share rose 9%, or $621, in a single year, according to KFF’s release, so workers are absorbing more of each increase.
Two details put the number in context:
- Over five years: KFF found family premiums rose 28%, compared with 26.9% for wages and 24.4% for inflation. Family coverage has now outrun both over that stretch, and a 5% year adds about $1,310 to the total premium.
- Who is paying more: Many large employers are shifting costs to workers. KFF found 44% of large firms that raised costs increased the share of premium workers pay, and 21% raised deductibles or other cost sharing.
How much does Marketplace health insurance for a family of four cost in 2027?
It depends on where you live, your ages, and your income. The anchor number is the benchmark premium, the second-lowest-cost Silver plan in your area, which is also what subsidies are calculated against. KFF reports the national average benchmark for a 40-year-old reached $625 a month in 2026, up from $497 in 2025.
A family pays for every member, each priced by age. Using the CMS age curve, two 40-year-old parents and two children under 15 cost about 3.2 times a single 40-year-old. That is roughly $2,000 a month at the 2026 national average, and about $2,300 a month if the 2027 increase lands at the proposed median. These are illustrations, not quotes. Older parents, teenagers, or an expensive state push the number higher, and a cheap market pushes it lower.
How much are 2027 premiums going up for health insurance for a family of four?
The Peterson-KFF analysis of 2027 filings found a median proposed increase of 15% across 276 insurers in all 50 states and DC, the second straight year of double-digit hikes. The 2026 median proposed increase was 18% and the median finalized increase was 20%. Proposed changes in the filings ran from a 1% decrease to a 54% increase.
Insurers point to rising health care prices as the main driver, along with the expiration of the enhanced premium tax credits and a sicker risk pool. These are proposed rates, so final numbers can change. Our state-by-state look at 2027 rates has the details.
What does health insurance for a family of four cost after subsidies?
Premium tax credits, not sticker prices, decide what most families pay for health insurance for a family of four on the Marketplace. The enhanced subsidies that removed the income cap and limited payments to 8.5% of income have expired, so the original rules apply for 2027, including the 400% poverty-level cutoff.
IRS Revenue Procedure 2026-26 sets the share of income a household must put toward the benchmark Silver plan. The share starts at 2.15% below 133% of poverty, rises on a sliding scale, and reaches 10.22% at 300% of poverty and stays there through 400%. The tax credit covers the rest of the benchmark premium.
For 2027 coverage the Marketplace uses the 2026 poverty guideline, which is $33,000 for a family of four. Here is what that means at each income level, using the illustrative $2,300 benchmark above:
| Household income | Share of poverty level | Expected monthly cost | Approximate monthly credit |
|---|---|---|---|
| $49,500 | 150% | about $177 | about $2,120 |
| $66,000 | 200% | about $373 | about $1,924 |
| $80,000 | 242% | about $558 | about $1,739 |
| $99,000 | 300% | about $843 | about $1,454 |
| $120,000 | 364% | about $1,022 | about $1,275 |
| $132,000 | 400% | about $1,124 | about $1,173 |
The expected cost is the amount you pay for the benchmark plan. Choose a cheaper Silver or a Bronze plan and you pay less, and choose a pricier one and you pay the difference.
What is the 400% income cutoff for a family of four in 2027?
It is $132,000. Above that, a family of four gets no premium tax credit, no matter how large the premium is relative to income. There is no phase-out. A family at $131,999 may receive a credit worth about $14,000 a year in the illustration above, while a family at $132,001 pays full price. This is the subsidy cliff, and it applies in full for 2027 unless Congress changes the law before enrollment. For the full picture, see the ACA subsidy cliff.
The cliff also raises the stakes on estimating income. Repayment caps are gone for tax years after 2025, so a family that receives advance credits and ends the year over $132,000 may owe the whole credit back. Our guide to calculating your real ACA subsidy shows how to estimate income correctly.
Should a family at $80,000 buy Bronze or Silver?
Often Silver, which changes the common advice. A family of four at $80,000 is at 242% of poverty, which is under the 250% line ($82,500). Households up to 250% of poverty who choose a Silver plan can qualify for cost-sharing reductions, which lower deductibles, copays, and out-of-pocket maximums. Those extra savings only come with Silver, so a Bronze plan with a lower premium can end up costing a family more if someone needs care.
The 2027 out-of-pocket maximum is $12,000 for an individual and $24,000 for a family on standard plans, so the protection built into cost-sharing reductions can be worth thousands. Compare total expected costs, not just the monthly premium.
Is my employer’s health insurance for a family of four considered affordable?
It depends on what your employer charges to add your family, not just what it charges you. Before the fix, the IRS judged affordability for everyone in the household using only the employee-only price. If your own coverage was cheap but adding your spouse and kids cost thousands more, your family still counted as having an affordable offer and could not get Marketplace credits. That problem was known as the family glitch. Under an IRS rule finalized in 2022, family members are now tested against the cost of family coverage. The worker is still tested on the employee-only price, so a worker with affordable self-only coverage still cannot get credits. For 2027 the test is the 10.22% figure explained in our 2027 ACA affordability threshold guide.
Here is how that plays out. At $80,000 of household income, 10.22% is $8,176 a year. The average family worker contribution of $7,471 falls below that, so the family would generally be treated as having affordable coverage and would not receive Marketplace credits. At $65,000, 10.22% is $6,643, and the same $7,471 contribution would not be affordable. Your own employer’s cost can be much higher or lower than the average, so ask HR for the exact family premium.
Can my kids qualify for CHIP or Medicaid even if I don’t?
Possibly. Many states cover children in families with incomes well above the Medicaid line through the Children’s Health Insurance Program, and the limits vary a lot by state. KFF tracks Medicaid and CHIP income limits for children by state. A family can have children on CHIP and parents on a Marketplace plan, which sometimes costs less than covering all four on one plan. Check your state’s limit before you pick a family plan.
How can a family of four keep health insurance affordable under the $132,000 cliff?
Lowering modified adjusted gross income (MAGI) is the main lever for keeping health insurance for a family of four affordable, and it can be worth a lot when a family is close. Common ways include:
- HSA contributions. The 2027 HSA limit for family coverage is $9,000, with a $1,000 catch-up at 55 and older. You need a qualifying high-deductible plan, and Bronze and catastrophic Marketplace plans have been HSA-eligible since January 1, 2026.
- Traditional retirement contributions. Pre-tax 401(k) or traditional IRA contributions lower MAGI.
- Self-employed deductions. Business expenses and certain retirement plans reduce net income.
A household at $135,000 that makes a $9,000 HSA contribution lands near $126,000, back under the line and eligible for roughly $1,200 a month in illustrated credits. MAGI is calculated on the tax return, so confirm your numbers with a tax professional.
What are the 2027 open enrollment dates?
On HealthCare.gov, open enrollment runs November 1, 2026 through January 15, 2027, and you must enroll by December 15, 2026 for coverage starting January 1. Some state-run marketplaces, including Covered California, run until January 31. Our guides to exact 2027 open enrollment dates and what is different this year have the full list.
What should a family know about claim denials?
Even a fully compliant ACA plan does not guarantee every bill gets paid. KFF found HealthCare.gov insurers denied about 19% of in-network claims in 2024, and consumers rarely appeal even though appeals can succeed. Know your plan’s appeal rights before you need them, and see how ACA claim appeals work.
What are the alternatives if health insurance for a family of four is unaffordable?
Families just over the cliff, or priced out by high premiums, have other options to understand before going without health insurance for a family of four.
Modern Health Sharing. A Health Sharing arrangement that combines community cost sharing with real advocacy support, helping members navigate the healthcare system as self-pay patients, access transparent pricing, reduce overall healthcare spending, and understand their bills, all in one coordinated approach. Health Share members are not covered by a state-regulated insurance policy, and sharing follows written Member Guidelines. For perspective, KFF found HealthCare.gov insurers denied about 19% of in-network claims in 2024, so read the guidelines of any program, insured or not. Compare in ACA vs. Health Share for individuals and how cost sharing works in a Health Share.
Direct Primary Care. A monthly membership with a primary care doctor for routine visits. It is not insurance and does not cover hospital care, so it is usually paired with another plan. See what is Direct Primary Care.
Short-term plans. Medically underwritten, limited in benefits, and not ACA-compliant, so they can decline you based on health history. Rules on length differ by state and federal policy, so confirm what is allowed where you live. See short-term medical vs. Health Share.
MEC plans. Minimum essential coverage plans are lower-cost options with thinner benefits than a full ACA plan. See what is a MEC plan.
ICHRA. If an employer offers one, it can reimburse an individual-market plan. See what is an ICHRA.
Plans cost the same on or off the Marketplace, but only Marketplace plans can receive premium tax credits, so shopping off-exchange makes sense only if you do not qualify for credits.
Frequently asked questions
What is the average cost of health insurance for a family of four in 2027? There is no single published figure. The building blocks are a $625 national average benchmark for a 40-year-old in 2026, a proposed median increase of 15% for 2027, and employer family coverage that averaged $28,303 in 2026.
What is 400% of the federal poverty level for a family of four in 2027? It is $132,000, based on the 2026 poverty guidelines used for 2027 coverage. Above that, a family receives no premium tax credit.
Is the ACA subsidy cliff back for 2027? Yes, and it changes health insurance for a family of four more than any other household size. The enhanced credits that removed the 400% cap expired at the end of 2025, so subsidies end at 400% of poverty unless Congress passes new legislation.
Why did ACA premiums go up again for 2027? For health insurance for a family of four, insurers cite rising health care prices, the expiration of the enhanced credits, and a sicker risk pool. The median proposed increase is about 15%.
What can a family do if it is just over the cliff? Lower MAGI through HSA or traditional retirement contributions, price Bronze and Silver plans, check whether the children qualify for CHIP, and compare alternatives such as short-term plans, MEC plans, and Modern Health Sharing.
