How coverage works
What the metal levels really buy
Bronze, silver, gold, and platinum describe one thing: how much of the bill the plan carries. Everything people assume they mean beyond that is wrong.
Actuarial value, plainly
The metal level is a measure called actuarial value: across a standard population, what share of total covered medical costs does the plan pay? Bronze pays around 60% and you carry 40%. Platinum pays around 90% and you carry 10%.
It is a statement about a population, not about you. In a year with no claims your platinum plan pays nothing and your bronze plan pays nothing, and you paid a great deal more for the platinum. In a year with a hospital admission the ranking reverses sharply.
| Metal | Plan pays | You pay | Premium | Suits |
|---|---|---|---|---|
| Bronze | ~60% | ~40% | Lowest | Low expected use, healthy cash reserve |
| Silver | ~70% | ~30% | Moderate | Anyone under 250% of poverty, without exception |
| Gold | ~80% | ~20% | High | Regular care, ongoing prescriptions |
| Platinum | ~90% | ~10% | Highest | Heavy predictable use; not sold everywhere |
What happened in 2026
Premiums rose sharply and people traded down. The silver share of the market fell from 57% to 43%, a record low, while bronze rose from 30% to 40% and bronze enrollment grew from 7.3 million to 9.2 million people.
Some of that was rational: households above 250% of poverty gain nothing from silver and were right to chase a lower premium. But cost-sharing reduction eligibility did not change at all in 2026, which means a substantial number of the people who moved to bronze walked away from a benefit they still qualified for. Average deductibles rose 37% that year, from $2,759 to $3,786, and the shift to bronze is a large part of why.
How the credit interacts with the choice
Your premium tax credit is calculated against the benchmark, which is the second-lowest silver plan in your area. The credit does not change when you pick a different metal level.
- Buy a plan cheaper than the benchmark and you keep the whole credit, so your premium falls. Some bronze plans end up at zero premium this way.
- Buy gold or platinum and you pay the difference above the benchmark yourself.
- You can never increase your credit by buying a more expensive plan.
One consequence worth knowing: because of how silver plans are priced to fund cost-sharing reductions, gold plans are occasionally cheaper than silver for people who do not qualify for those reductions. It is worth checking rather than assuming the order runs cheapest to dearest.
How to choose, in three questions
1. Are you under 250% of the federal poverty level?
Then buy silver. The rest of this section does not apply to you.
2. Could you actually pay the out-of-pocket maximum?
If a $12,000 year would be survivable but painful, a middling plan is usually the right answer. If it would be catastrophic, buy up. If you have a genuine reserve and no ongoing care, bronze is defensible.
3. What do you actually use?
Add up last year: visits, prescriptions, specialists, therapy, imaging. If you take a regular medication or see a specialist quarterly, the higher premium usually returns itself. If you saw a doctor twice, it usually does not.
Common questions
What do the metal levels actually mean?
They describe actuarial value: the share of total covered medical costs the plan pays across a standard population. Bronze pays about 60%, silver about 70%, gold about 80%, platinum about 90%. They say nothing about the quality of care, the network, or which doctors are included.
Is bronze the cheapest option?
It has the lowest premium. Whether it is the cheapest depends on what care you use. Bronze plans carry high deductibles, so if you qualify for cost-sharing reductions and buy bronze instead of silver, you are usually worse off across the year even though the monthly figure looks better.
Why is silver special?
Because cost-sharing reductions only attach to silver plans. If your income is between 100% and 250% of the federal poverty level, a silver plan is upgraded to 73%, 87%, or 94% actuarial value at no extra premium. At the top tier a silver plan behaves better than most platinum plans.
Does a higher metal level mean better doctors?
No. Metal level describes cost sharing only. Network, drug formulary, and referral rules are set separately by the plan, and a bronze plan and a gold plan from the same insurer frequently share the identical network.
