If you live in one of the places where the gold plan is cheaper than the silver plan, and you earn more than about $24,000, you should not buy the more expensive silver option. The gold plan will cost less, and have a lower deductible. There are also high-deductible bronze plans that will have substantially lower premiums that you may also want to consider. If you qualify for a government subsidy, those will be your best options.

If you earn too much to qualify for federal help buying insurance, you should also steer clear of the more expensive silver plans on HealthCare.gov. But there may be cheaper options in the silver category if you buy directly from an insurance company. A broker may be able to help you examine all of those options.

If you earn less than $24,000, a silver plan will still be your best choice. That’s because you qualify for additional discounts that will lower your deductible and co-payment, making a silver plan even more generous than a gold plan. Premium subsidies, which are unaffected by the president’s actions, will protect you from premium price increases.

The loading of cost increases onto silver plans also makes it hard to easily describe how much more expensive insurance will be next year, compared with this year. The consulting group Avalere Health published a report Wednesday saying that the average silver plan on HealthCare.gov would increase in price by 34 percent — by far the largest annual price increase since the Obamacare markets began.

Normally, that silver price increase is a good barometer for what’s happening with the entire health insurance market. But the Avalere report highlighted that the prices of other plan types aren’t rising as fast. Gold plans are going up, on average, by 16 percent. Bronze plans are rising, on average, by 18 percent.

Some of those increases are probably because of Trump administration actions as well. The government has cut back on advertising and outreach to help enroll healthy customers, and has signaled that it may not enforce the government mandate to obtain insurance as vigorously as the Obama administration did. In their filings with regulators, insurance companies said they were increasing premiums to address that broader policy uncertainty.

Our map draws on prices that were published online Wednesday for 2018 plans on HealthCare.gov. The website serves 39 states, and the precise prices we examined were for single customers who don’t smoke, age 40, though the trends should be the same for customers with different family sizes and ages. Information from the remaining states, which run their own marketplaces, will become available next week.
