How to Choose Health Insurance
Verified Oct 19, 2026Choosing health insurance comes down to five checks: where you're buying (employer or Marketplace), what the plan category means, what it costs in total (not just the premium), whether your doctors and drugs are covered, and when you can enroll. Get those five right and the choice mostly makes itself.
This guide walks through each check in order, using HealthCare.gov's official guidance and KFF's cost data. No plan recommendations — just the decision process.

Step 1: Know where you're shopping
Most people choose between employer coverage and the Health Insurance Marketplace. If your employer offers coverage, check it first — employer plans typically come with the employer paying most of the premium (workers pay 16% of single premiums on average, per KFF).
One rule matters here: if you're offered job-based coverage that provides minimum value (designed to pay at least 60% of medical costs for a standard population, including substantial hospital and physician coverage) and is affordable, you're not eligible for a premium tax credit through the Marketplace. For 2026, coverage counts as affordable if your share of self-only coverage doesn't exceed 9.96% of household income — that figure comes from IRS Revenue Procedure 2025-25 as cited by benefits analysts (EY, Gallagher, Hylant); the IRS bulletin page itself wasn't directly retrievable, so treat it as corroborated rather than primary-verified.
Step 2: Decode the metal categories
On the Marketplace, plans come in metal categories that describe cost-sharing — not quality: Bronze plans pay about 60% of costs on average, Silver about 70%, Gold about 80%, and Platinum about 90%. HealthCare.gov is explicit: the categories have nothing to do with the quality of care.
Two details matter enormously. First, Silver plans with cost-sharing reductions effectively pay 73–94% for eligible enrollees — often the best value on the Marketplace. Second, the extra savings (cost-sharing reductions and the strongest premium tax credits) only apply to Silver plans — pick Bronze and you leave them on the table.
Step 3: Compare total yearly cost, not just the premium
HealthCare.gov's core advice: think about your total spending on health care, not just the premium when picking a plan category. A Bronze plan's low premium can be dwarfed by its deductible in a year you actually need care; a Gold plan's higher premium can be the cheaper choice for someone with ongoing treatment.
Do the arithmetic for two scenarios: a healthy year (premiums + a couple of copays) and a high-care year (premiums + full deductible + coinsurance up to the out-of-pocket max). The plan that wins both scenarios is rarely the one with the lowest premium alone.
Step 4: Check the network before you fall in love with the premium
HMO and EPO plans generally don't cover routine out-of-network care — if your doctors aren't in-network, you pay full price. Before enrolling, verify that your primary care doctor, specialists, and preferred hospital are in the plan's network.
This check kills more bad choices than any other. A cheap premium on a plan your doctor doesn't take isn't cheap — it's a different, more expensive plan wearing a disguise.
Step 5: Check the drug formulary
If you take prescription drugs regularly, check the plan's formulary (covered-drug list) and which tier your drugs sit on — copays and coverage vary by tier within a plan. A plan that's perfect on every other dimension can still be wrong if your $300-a-month medication isn't covered.
This is standard plan-shopping practice worth making explicit: formularies differ plan to plan, and the difference lands directly in your wallet every month.
Step 6: Mind the calendar
Federal Marketplace open enrollment runs November 1 to January 15 each year. Enroll by December 15 for coverage starting January 1; enroll December 16 through January 15 for coverage starting February 1.
Outside open enrollment, you can only enroll with a qualifying life event (marriage, birth, job loss, move — a Special Enrollment Period) or through Medicaid/CHIP, which enroll year-round. Miss the window without a qualifying event and you're waiting for next November.
Common mistakes to avoid
The same errors show up every enrollment season:
- Shopping on premium alone. Total yearly cost — premium plus deductible plus cost-sharing — is the real price.
- Assuming metal means quality. Bronze through Platinum describe cost-sharing splits, nothing more.
- Skipping the network check. Especially with HMO/EPO plans, out-of-network means uncovered.
- Ignoring the formulary. Drug tiers vary within a plan and between plans.
- Forgetting preventive care is free in-network. Screenings and checkups cost you nothing — use them.
- Missing the enrollment window. November 1 to January 15, with the December 15 cutoff for January 1 coverage.
Key costs, at a glance
| What | Figure | Source |
|---|---|---|
| Average annual premium, single coverage (benchmark) | $9,325/year | KFF — 2025 Employer Health Benefits Survey as of 2025 (released Oct 2025) |
| Average annual premium, family coverage (benchmark) | $26,993/year | KFF — 2025 Employer Health Benefits Survey as of 2025 (released Oct 2025) |
Averages mask wide state-by-state variation. Your premium depends on your profile, location, and coverage choices.
Who it's best for — and who can skip it
You may not need it if
- People with only one plan option — the decision is already made
- Medicare/Medicaid shoppers — different programs, different rules
How to compare
- Check employer coverage first — minimum value and affordability decide Marketplace subsidy eligibility
- Treat metal categories as cost-sharing splits, not quality grades
- Run total-cost math for a healthy year and a high-care year
- Verify your doctors, hospital, and drugs are covered before enrolling
- Remember Silver unlocks cost-sharing reductions; other metals don't
- Hit the enrollment window: Nov 1–Jan 15, Dec 15 cutoff for Jan 1 start
Your next step
Gather your options' four numbers — premium, deductible, out-of-pocket max, and your doctors' network status — then run the two-scenario total-cost math from Step 3. If a high-deductible option survives the math, the HDHP and HSA guide covers the 2026 limits; if the vocabulary trips you up, start with deductibles, copays, and coinsurance explained.
How to Choose Health Insurance FAQs
Can I get Marketplace subsidies if my job offers health insurance?
Not if the job-based coverage provides minimum value and is affordable. Minimum value means the plan is designed to pay at least 60% of medical costs for a standard population with substantial hospital and physician coverage. If both tests are met, you're not eligible for a premium tax credit.
What do the metal categories actually measure?
The share of average costs the plan pays: Bronze ~60%, Silver ~70%, Gold ~80%, Platinum ~90%. They say nothing about quality of care. Silver is special because cost-sharing reductions — which can raise the plan's share to 73–94% — only apply to Silver plans.
When can I enroll in a Marketplace plan?
Federal open enrollment runs November 1 to January 15. Enroll by December 15 for coverage starting January 1; enroll December 16–January 15 for February 1 coverage. Outside that window you need a qualifying life event (Special Enrollment Period); Medicaid and CHIP enroll year-round.
What if I miss open enrollment?
You'll generally wait until the next open enrollment unless you have a qualifying life event — like losing job-based coverage, getting married, having a baby, or moving. Those trigger a Special Enrollment Period. Medicaid/CHIP remain available year-round if you qualify.
Are preventive services really free?
When in-network, yes. Most plans — including all Marketplace plans — must cover a set of preventive services like screenings and immunizations at no cost to you: no copay, no coinsurance, even before you've met your deductible.
Should I pick Bronze or Silver on the Marketplace?
It depends on subsidies and expected care. Silver unlocks cost-sharing reductions and the strongest premium tax credits, which often makes it the best value — especially for eligible lower-income shoppers. Bronze usually wins only if you're ineligible for extra savings and expect minimal care. Run the total-cost math both ways.
