How to Compare Health Insurance Plans: Premiums, Deductibles, Networks, and Coverage

A plan that costs $130 less per month saves $1,560 in premiums over a year. That sounds like an easy choice—until a hospital stay, a costly prescription, or an out-of-network specialist wipes out the savings. The cheapest premium tells you what it costs to keep coverage. It doesn’t tell you what it costs to use it.

A useful comparison has two parts: what you’re likely to spend in an ordinary year, and what you could afford to spend in a bad one. Then check whether the plan gives you practical access to the doctors, hospitals, and medications you need. A low estimated cost is little comfort if the specialist you rely on isn’t in the network.

Compare yearly costs, not monthly premiums

Start with the premium you would actually pay, after any employer contribution or Marketplace premium tax credit. Multiply it by 12 for a full year of coverage. Then estimate what you would pay for care under each plan. HealthCare.gov’s total yearly cost framework combines premiums with expected spending on deductibles, copayments, and coinsurance; its Marketplace comparison tool can show estimates for low, medium, or high use of care. An estimate is a way to compare plans, not a promise of what your bills will be.

Use the same expectations for every plan. List your regular prescriptions, routine appointments, therapy, specialist visits, and any tests or procedures you reasonably expect. Last year’s claims can help, but adjust for known changes: a planned surgery, a new medication, or a child who will need ongoing care.

Here’s why the premium alone can mislead. These figures are hypothetical and assume all care is covered and in-network.

Plan A saves $1,560 in premiums. If you use little care, it may cost less overall. If covered in-network care pushes you to the out-of-pocket maximum, Plan B costs $2,440 less for the year. Neither outcome tells you exactly what will happen; together, they show the trade-off you’re making.

The last row is a planning figure, not an absolute ceiling on every health expense. It does not account for services the plan doesn’t cover or certain out-of-network charges. Compare both the likely-year estimate and this higher-cost scenario against your savings and cash flow.

Read the deductible alongside copays and coinsurance

The deductible is the amount you pay for covered services subject to it before the plan starts sharing those costs. Once you meet it, you may still owe a fixed copay or a percentage called coinsurance. A $2,000 deductible, for example, does not mean all later care is free. Some services have copays before the deductible; some plans have a separate prescription drug deductible; and family plans often have both individual and family deductibles. Check the deductible rules for each plan rather than treating the number on the comparison screen as your entire expected bill.

For each service you expect to use, ask two questions: “Does the deductible apply?” and “What do I pay afterward?” A $35 primary care copay that applies before the deductible can be valuable to someone with frequent visits. For an expensive procedure, the specialist, facility, imaging, and anesthesia charges may each be handled differently.

Don’t add the deductible to every copay and then add the out-of-pocket maximum on top. Payments that qualify for the maximum are part of that limit, not an extra charge beyond it. What matters is how quickly your spending would build under each plan’s rules.

Treat the out-of-pocket maximum as a risk measure—with limits

For covered in-network benefits, the out-of-pocket maximum limits the deductible, copays, and coinsurance you pay during the plan year. Once you reach it, the plan pays 100% of the cost of covered in-network benefits for the rest of that period. The limit does not include premiums, noncovered services, out-of-network care, or charges above a plan’s allowed amount.

This number deserves attention even if you’re healthy. You can’t predict an injury or serious illness from last year’s spending. Ask whether you could pay several thousand dollars early in the year, before an insurer has processed every claim. Two plans with similar estimated annual costs may feel very different if one exposes you to a much larger bill before cost sharing improves.

For family coverage, compare the individual and family limits separately. If one person has substantial needs, the individual limit may matter most. If several people use care, the family limit becomes more important. Read the plan documents for how each applies.

Check the exact provider network

A familiar insurer name doesn’t guarantee a familiar doctor is covered. Insurers can offer multiple networks, and a physician’s participation in one plan does not establish participation in another. Check the directory for the exact plan, then confirm important providers with both the insurer and the provider’s office. HealthCare.gov recommends checking the plan directory and asking about specific doctors before relying on them for care.

Start with people and places that would be hard to replace: your primary care doctor, specialists, therapist, preferred hospital, and nearby lab or imaging center. Ask the office whether it accepts the exact network and whether it is taking new patients. For a planned procedure, confirm the facility as well as the physician.

Plan labels offer a starting point, not a substitute for this check. A PPO generally allows out-of-network care at additional cost; an HMO generally limits coverage outside its network except in emergencies; an EPO generally covers care only in-network except in emergencies; and a POS plan uses referrals to see specialists. The network rules for HMOs, PPOs, EPOs, and POS plans still leave important details for each plan’s documents.

Federal surprise-billing protections cover many emergencies and certain out-of-network services received at in-network facilities. They do not make every planned out-of-network visit an in-network visit. Check access before enrolling rather than relying on a billing protection to solve a network mismatch.

Compare coverage for the care you’ll actually use

Plans may cover the same broad type of care while charging very different amounts for a particular drug, service, or setting. Get each plan’s Summary of Benefits and Coverage, or SBC. This standardized document lets you compare deductibles, limits, common services, and coverage examples side by side. You can request an SBC for individual or job-based plans when shopping.

Use it to flag questions, then consult the full plan documents or ask the insurer for details. Pay particular attention to services you expect to use, including outpatient surgery, mental health care, physical therapy, maternity care, or durable medical equipment. Check whether a service requires prior authorization, has visit limits, or costs more at a hospital outpatient department than at another covered site.

For medications, look beyond “prescription drugs covered.” Check each drug’s name and dosage on the plan’s formulary, its cost-sharing tier, whether the drug deductible applies, and whether your pharmacy is in-network. A covered drug may still cost more than you expect. You can check a plan’s covered medications and pharmacy network through the insurer.

Also separate medical coverage from other kinds of help. Most health insurance does not pay for long-term custodial care, such as ongoing help with bathing or dressing. If that is a concern for your family, comparing in-home and residential care costs is a separate planning task. Before an international trip, check what your health plan covers abroad; if the protection is thin, a separate comparison of travel medical limits and exclusions may be useful. Travel medical coverage addresses a different risk from routine health insurance.

Apply savings before choosing a plan

If you’re shopping through the Marketplace, compare plans using your estimated premium tax credit—not the full, unsubsidized premium. Also check whether you qualify for cost-sharing reductions. These lower deductibles, copays, coinsurance, and out-of-pocket maximums, but you must choose a Silver Marketplace plan to receive them. A discounted Silver plan can therefore be worth comparing even when another metal level shows a tempting premium.

For job-based coverage, use your share of the premium after the employer contribution. If you’re weighing a job-based offer against Marketplace coverage, don’t assume you’ll qualify for Marketplace savings: an offer that meets affordability and minimum-value rules can affect eligibility. Check that question before building a comparison around a discounted Marketplace price.

Make the choice with three checks

Narrow the field to plans that cover your essential care and have usable provider networks. Then, for each remaining plan:

1. Calculate 12 months of your premium plus a realistic estimate of in-network care and prescriptions.
2. Calculate 12 months of your premium plus the applicable in-network out-of-pocket maximum, and ask whether you could manage that expense.
3. Resolve any uncertainty about a key doctor, drug, procedure, or authorization requirement before enrolling.

If one plan costs less in your likely year and offers access to the care you need, the decision may be straightforward. If the cheaper plan carries much greater financial risk, decide deliberately whether the premium savings are worth it. The strongest choice is one you can use—not simply one you can afford to enroll in.
