Metal Tiers

Metal tiers are the four plan categories on the ACA Marketplace — Bronze, Silver, Gold, and Platinum. The tier tells you how costs are split between you and your insurance company on average across a large group of enrollees. It does not reflect how much your individual care will cost.

Each tier is defined by its actuarial value: the percentage of average health care costs the plan covers. You cover the rest through deductibles, copays, and coinsurance.

Compares the four ACA Marketplace metal tiers — Bronze, Silver, Gold, and Platinum — by the percentage of average health care costs the plan covers versus what you pay, and which type of consumer each tier is best suited for. Silver plans are the only tier eligible for Cost-Sharing Reductions (CSR).
Metal Tier Plan covers (avg) You pay (avg) Best for
Bronze 60% 40% Healthy, low-usage; wants lowest monthly premium
Silver CSR eligible 70% 30% CSR-eligible families; moderate care use
Gold 80% 20% Regular care users; no CSR eligibility
Platinum 90% 10% High care users; predictable costs are the priority
Percentages reflect actuarial value — the average across a large group of people, not a guarantee of your individual split. CSR (Cost-Sharing Reduction) is only available on Silver plans for households between 100%–250% FPL.

A higher metal tier means lower out-of-pocket costs when you use care, but a higher monthly premium. The right tier depends on how much care you expect to use and whether you qualify for Cost-Sharing Reductions (CSR) — which are only available on Silver plans.

Catastrophic plans exist as a fifth category for people under 30 or those with a hardship exemption, but they are not part of the metal tier system.

Frequently Asked Questions

Does a higher metal tier mean better coverage?

Not necessarily. A higher tier means lower out-of-pocket costs when you use care, but a higher monthly premium. If you qualify for CSR on a Silver plan, Silver often outperforms Gold on total annual cost despite having a lower actuarial value. The best tier depends on your expected care use, income, and subsidy eligibility.

Do all metal tiers cover the same services?

Across all metal tiers, ACA plans must cover the same 10 Essential Health Benefits — including preventive care, emergency services, prescription drugs, and mental health care. What changes between tiers is not what’s covered, but how much you pay when you use covered services.
