Metal tiers are not quality ratings. A platinum plan is not better care than a bronze plan, and it does not cover more conditions. Every marketplace plan covers the same ten essential health benefits and the same free preventive services. The tier tells you one thing: how the bill gets split between you and the insurer.
The single most valuable thing on this page is further down, in the silver section, and it is worth several thousand dollars a year to the people it applies to. This guide covers the United States ACA marketplace; for the wider picture of how it fits alongside other coverage, see our health and life insurance guide.
The Four Tiers
| Tier | Plan pays, on average | You pay, on average | Suits |
|---|---|---|---|
| Bronze | 60% | 40% | Low expected use; you want protection against a disaster, not help with routine costs |
| Silver | 70% | 30% | Anyone under 250% FPL — see below. Otherwise a middle option |
| Gold | 80% | 20% | Regular prescriptions, predictable ongoing care |
| Platinum | 90% | 10% | Heavy, certain use. Not sold everywhere |
These percentages describe actuarial value — the share of costs a plan covers across a large standard population, as HealthCare.gov sets out in its plan category rules. They are not a promise about your year. A bronze plan does not pay 60% of each of your bills; it pays nothing until your deductible is met, then a great deal after it.
Insurers have some latitude around each target, so a plan labelled bronze may sit slightly above or below 60%. Marketplace silver plans are held to the tightest range, because premium tax credits are pegged to them.
⭐ If Your Income Is Under 250% FPL, Buy Silver
This is the part that costs people the most money when they get it wrong.
Cost-sharing reductions are available only on silver plans. Not bronze, not gold, not platinum. If your household income is between 100% and 250% of the federal poverty level and you buy a bronze plan because the premium looked cheaper, you have forfeited them entirely.
CSRs work by quietly upgrading the silver plan you bought. Depending on income, a silver plan’s actuarial value rises to:
- 73% — for incomes toward the upper end of the range
- 87% — for middle incomes in the range
- 94% — for the lowest incomes in the range
A 94% silver plan is more generous than a platinum plan, and you pay a silver premium for it. Deductibles and out-of-pocket maximums drop substantially at the same time — a point healthinsurance.org makes in its breakdown of metal plans.
You do not apply for this separately. It attaches automatically when you enrol in a silver plan and your income qualifies. The only way to lose it is to buy a different tier.
If your income sits below 100% FPL, the marketplace may not be your route at all — in expansion states you would likely qualify for Medicaid instead, which costs nothing and has no open enrollment period.
Why the Cheapest Premium Is Not the Cheapest Plan
The second thing worth understanding is how the subsidy actually works, because it changes what “cheaper” means.
Your premium tax credit is a fixed dollar amount, calculated against the benchmark silver plan in your area. It does not change based on which tier you buy. Take that same fixed credit to a bronze plan and you pay less per month — sometimes nothing. Take it to gold and you pay more.
So the real question is not “which tier is cheapest” but “where should I spend a fixed subsidy”. And the answer depends on how much care you expect to need, because a bronze plan with a $0 premium can still cost you thousands the first time you actually use it.
One important change: the enhanced premium tax credits that ran from 2021 through 2025 expired on 31 December 2025. The subsidy cliff above 400% FPL is back, meaning households above that threshold generally pay full price. That is also why catastrophic plan eligibility was widened for people over 30 — the group that lost help is precisely the group that new route was opened for.
Out-of-Pocket Maximums, and the 2027 Jump
The out-of-pocket maximum is the number that caps your exposure in a genuinely bad year. It matters more than the deductible for anyone managing a condition.
| 2026 | 2027 | |
|---|---|---|
| Individual ceiling | $10,600 | $12,000 |
| Family ceiling | $21,200 | $24,000 |
| Some bronze plans may reach | — | Up to $15,600 |
That is a significant increase, and the bronze exception is new: a 2026 rule change allows certain bronze plans to carry out-of-pocket limits up to 130% of the standard ceiling, provided the insurer also offers a bronze plan within the normal limit. If you are shopping bronze for 2027, check the specific out-of-pocket maximum rather than assuming it matches the federal cap.
Plans can always set lower limits than the ceiling, and gold, platinum and CSR silver plans commonly do. Note also that CMS changed the actuarial value calculator for 2027, which shifts cost-sharing at the platinum and 94% silver levels — another reason to read the specific plan documents rather than trusting the tier label alone.
Bronze Plans and HSAs
As of 2026, all individual-market bronze and catastrophic plans qualify as HSA-compatible high-deductible health plans. Previously most did not.
If you are healthy, above the CSR income range, and choosing bronze, pairing it with a health savings account is the strongest version of that strategy — contributions reduce taxable income, unspent money rolls forward, and you build a fund against the deductible you are exposed to. This is particularly worth modelling if you are self-employed and buying your own coverage, since the premiums may also be deductible.
What the Tier Does Not Tell You
Two plans at the same metal level can differ enormously on things the label says nothing about.
- The network. Whether your doctor and your hospital are in it. This is the most common source of surprise bills and the tier is silent on it.
- The drug formulary. Whether your specific medication is covered, and on which cost tier.
- Plan type — HMO, EPO or PPO — which governs referrals and out-of-network access. Our guide to how Anthem structures its HMO, EPO and PPO plans walks through what the differences mean in practice, and the same logic applies to Aetna’s HMO and PPO options.
- How the deductible is structured, including whether some services are covered before you meet it.
Platinum is also simply unavailable in many counties, and where it exists the premium gap over gold is often steep enough that only genuinely heavy users come out ahead. If dental, vision or hearing are what you are missing, those are usually bought separately as ancillary coverage rather than solved by moving up a tier.
When You Can Enrol
Open enrollment for 2027 coverage opens on 1 November 2026. The closing date is genuinely unsettled, and you should treat any single date you read — including here — as needing confirmation.
CMS finalised a rule in 2025 shortening the window to close on 15 December for states using HealthCare.gov, with state-run marketplaces required to finish by 31 December. Parts of that rule were stayed by a court, and reporting through mid-2026 indicates the federal marketplace is operating to 15 January 2027 in most states. Sources published within weeks of each other give different end dates.
Confirm the closing date on HealthCare.gov or your state marketplace before you rely on it, and if the earlier date applies where you live, missing it means waiting a year. Enrolling by 15 December has always been the safe move regardless, since it secures a 1 January start.
Outside open enrollment you need a special enrollment period, triggered by a qualifying life event — losing job-based coverage, marriage, a birth, moving state, or turning 26 and coming off a parent’s plan. You generally have 60 days. If the trigger was leaving a job, weigh a marketplace plan against continuing your old plan through COBRA, which keeps your network but usually costs considerably more. And if you are approaching 65, the marketplace stops being the right question — see our guide to Medicare enrollment and its permanent late penalties.
Frequently Asked Questions
No. All ACA marketplace plans cover the same ten essential health benefits and the same free preventive services regardless of tier. The metal level describes only how costs are split between you and the insurer. Quality of care depends on your doctors and hospital, which is a function of the plan’s network, not its tier.
If your household income is between 100% and 250% of the federal poverty level, choose silver — cost-sharing reductions are available only on silver plans and can raise the plan’s value to 94%, better than platinum, at a silver premium. Above that income range it depends on expected use: bronze if you rarely need care and want to pair it with an HSA, gold if you have regular prescriptions or predictable ongoing costs.
The share of total healthcare costs a plan covers for a large standard population — 60% for bronze, 70% silver, 80% gold, 90% platinum. It is a population average, not a prediction about your year. A bronze plan does not pay 60% of every bill; it pays nothing until the deductible is met and a great deal afterwards.
No. Cost-sharing reductions attach only to silver plans. This is the most expensive mistake in marketplace shopping: someone eligible for CSRs who buys bronze because the premium looked lower gives up a benefit that can be worth several thousand dollars a year. You do not apply for CSRs separately — they attach automatically when you enrol in silver and your income qualifies.
No. The premium tax credit is a fixed dollar amount calculated against the benchmark silver plan in your area, and it stays the same whichever tier you buy. Applying it to a bronze plan lowers your monthly cost, sometimes to nothing; applying it to gold raises it. The real question is where to spend a fixed subsidy, not which tier is cheapest.
$12,000 for an individual and $24,000 for a family, up from $10,600 and $21,200 in 2026. A 2026 rule change also allows certain bronze plans to carry out-of-pocket limits as high as $15,600, provided the insurer also offers a bronze plan within the standard ceiling — so check the specific figure on any bronze plan rather than assuming it matches the federal cap.
It opens on 1 November 2026. The closing date is genuinely unsettled: CMS finalised a rule shortening the window to 15 December for HealthCare.gov states, parts of that rule were stayed by a court, and reporting through mid-2026 indicates most states are operating to 15 January 2027. Confirm the date on HealthCare.gov or your state marketplace. Enrolling by 15 December is the safe move either way, since it secures a 1 January start.
