When shopping for health insurance on the Affordable Care Act (ACA) Marketplace, you’ll notice that plans are sorted into four categories: Bronze, Silver, Gold, and Platinum. These are known as the “metal tiers.” While the names may suggest differences in quality, the real distinction lies in how costs are shared between you and the insurance company.
Understanding how the metal tiers work—and how they affect your out-of-pocket costs—is crucial to choosing a plan that fits your health needs and budget. In this guide, we’ll break down each metal level, explain who each tier is best for, and clear up some common misconceptions.
What Are the ACA Metal Tiers?
The ACA metal tiers categorize health plans based on actuarial value (AV)—a measure of how much of your healthcare costs the plan is expected to cover over the course of a year.
Here’s a general breakdown:
| Metal Tier | Insurance Pays | You Pay (on average) |
|---|---|---|
| Bronze | 60% | 40% |
| Silver | 70% | 30% |
| Gold | 80% | 20% |
| Platinum | 90% | 10% |
These percentages are averages. For any individual person, actual expenses may vary depending on how much medical care they use.
Bronze Plans: Low Premiums, High Deductibles
Best for: Healthy individuals who rarely need care and want to protect themselves from worst-case scenarios.
Lowest monthly premiums
Highest deductibles and out-of-pocket costs
Often includes high coinsurance rates (you pay a percentage of services)
Preventive services are still covered at 100%, as required by law
Bronze plans are a good choice if you’re in relatively good health, don’t take many prescriptions, and can afford to pay more out of pocket if you need unexpected care. They’re often popular among younger adults and gig workers looking for affordable catastrophic protection.
Silver Plans: The Sweet Spot—Especially for Low-Income Enrollees
Best for: People with moderate healthcare needs or those eligible for cost-sharing reductions (CSRs).
Moderate premiums and moderate out-of-pocket costs
Only Silver plans qualify for CSRs, which significantly reduce deductibles, copays, and max out-of-pocket limits
A good balance between monthly cost and coverage
If your income is between 100% and 250% of the federal poverty level, and you qualify for ACA subsidies, a Silver plan with CSRs can offer Gold or Platinum-level coverage at a lower price.
For this reason, many lower-income households will get the most value from choosing a Silver plan over Bronze, even if premiums are slightly higher.
Gold Plans: Higher Premiums, Lower Costs When You Need Care
Best for: People who expect to use healthcare services regularly—such as managing chronic conditions or ongoing treatments.
Higher monthly premiums than Bronze or Silver
Lower deductibles and copays
Covers more of your costs up front
Helps avoid surprise expenses if you need frequent care or costly prescriptions
If you don’t qualify for cost-sharing reductions but anticipate needing a lot of care throughout the year, a Gold plan can be more cost-effective overall. You’ll pay more each month but less at the doctor’s office or pharmacy.
Platinum Plans: Highest Premiums, Minimal Out-of-Pocket Costs
Best for: People with chronic illnesses, complex healthcare needs, or those who want predictable costs.
Highest monthly premiums
Very low deductibles and copays
Often only offered in certain regions or to small groups
Least common tier on most Marketplaces
Platinum plans work well for those who know they will reach their out-of-pocket maximum every year and prefer to manage predictable monthly costs over uncertain high expenses.
A Quick Word on Catastrophic Plans
Though not part of the metal tiers, the ACA also offers Catastrophic plans to people under 30 or those who qualify for a hardship exemption.
Very low premiums, very high deductibles
Cover essential health benefits and preventive care
Ideal for emergency protection only
These plans do not qualify for premium subsidies or cost-sharing reductions and are not usually a better deal than a Bronze plan—especially for those eligible for financial assistance.
How Subsidies Work with Metal Tiers
One of the most important features of ACA coverage is the premium tax credit, which lowers the cost of your monthly premium based on your income.
Premium subsidies apply to all metal tiers (except Catastrophic)
Cost-sharing reductions apply only to Silver plans
For example, if a Silver plan has a $7,000 deductible without CSRs, a person with income near the federal poverty level might see that deductible reduced to $500—without changing the premium.
This makes subsidized Silver plans some of the most valuable health insurance options available for low-to-moderate income families.

Metal Tier Doesn’t Equal Quality
A common myth is that a Gold or Platinum plan is “better” than a Bronze plan in terms of healthcare quality. That’s not true.
All ACA-compliant plans must cover the 10 Essential Health Benefits
All plans offer free preventive services
Plans must meet network adequacy and provider standards
The tiers only reflect how you and the plan split the costs, not whether the care is better or more comprehensive.
How to Choose the Right Tier
Here are a few key questions to ask:
Do I qualify for subsidies or CSRs?
Do I expect to visit the doctor or specialist frequently?
Am I managing a chronic condition?
Can I afford high upfront premiums to save later?
Do I need prescription drug coverage and how much do my meds cost?
If you’re healthy and rarely need care → Bronze might work
If you qualify for CSRs → Always consider Silver
If you have regular medical expenses → Gold or Platinum may save you money over the year
Compare plans carefully during Open Enrollment (Nov 1–Jan 15 in most states), or during a Special Enrollment Period if you qualify due to a life event like job loss or marriage.
Bottom Line
The ACA metal tiers help simplify a complex decision: how much are you willing to pay now versus later? While the names Bronze through Platinum suggest a hierarchy, the “best” plan depends entirely on your income, health needs, and comfort with cost-sharing.
Whether you’re shopping for the first time or reevaluating your options, understanding the metal tiers gives you the power to make informed, cost-effective decisions.
