Open enrollment season means three plan summaries sitting open in your browser tabs, each with a grid of numbers that all look roughly the same. The instinct is to pick the lowest monthly premium and move on. That instinct is wrong about half the time, because the premium is only one of the three numbers that decide what you actually pay. Here is how to compare health insurance plans during open enrollment so the choice matches your real spending.
Total cost, not the premium
The number that matters is your total cost for the year: premiums plus what you expect to pay for care. A plan at $180 a month with a $7,000 deductible costs $2,160 guaranteed and up to $9,160 in a bad year. A plan at $340 a month with a $1,500 deductible costs $4,080 guaranteed and caps around $5,580 plus copays. If you are healthy and see a doctor twice a year, the cheap premium wins by thousands. If you are managing a condition with monthly visits and a prescription, the expensive plan usually wins back its premium and then some.
So run two scenarios for each plan you are considering: a normal year (your actual care from last year, roughly) and a bad year (a surgery or an ER visit). Add the premiums. Pick the plan with the lowest total in both scenarios, or the one that only loses in the bad year by an amount you can absorb. This takes fifteen minutes and it beats every shortcut. The deductible is what you pay before the plan pays; the out-of-pocket maximum is the ceiling that stops the bleeding, premiums not included. Those are the three numbers. Everything else on the summary page is commentary.
The metal tier shortcut
Bronze, Silver, Gold, and Platinum describe the plan's cost split, not its quality. Bronze means you pay more when you get care and less every month; Platinum is the reverse. The honest rule of thumb: healthy and low-spending, look at Bronze. Lower income and marketplace-eligible, look at Silver first, because the cost-sharing reductions that lower deductibles and copays only attach to Silver plans, and they can make a Silver plan better than Gold at a Bronze-ish price. High, predictable medical costs, look at Gold or Platinum.
Then the two checks everyone skips. Check the provider network for your actual doctors and hospital, not just "large network," because an out-of-network surgery bill ignores every number you just modeled. Check the drug formulary for your prescriptions, because the same drug can cost $10 on one plan and $200 on another. A plan with perfect numbers and the wrong formulary is the wrong plan. If you choose a high-deductible plan that meets the IRS thresholds ($1,700 individual or $3,400 family deductible for 2026), it can pair with a Health Savings Account, which lets you contribute $4,400 self-only or $8,750 family in 2026 with triple tax treatment. Our HSA explainer walks through why that account beats a regular savings account for medical money.

Frequently asked questions
When is open enrollment for health insurance?
On the federal marketplace, open enrollment runs November 1 through January 15 in most states. Some states run their own marketplaces with different dates, and employer plans usually hold their own enrollment in the fall.
What is the difference between the premium and the deductible?
The premium is what you pay every month to keep the plan, whether you see a doctor or not. The deductible is what you pay out of pocket for covered care before the plan starts paying its share.
Which metal tier is best: Bronze, Silver, Gold, or Platinum?
It depends on your expected care. Bronze usually wins for healthy people with low medical spending. Silver is the best value for lower-income buyers because cost-sharing reductions only attach to Silver plans. Gold and Platinum fit people with high, predictable medical costs.
Can you get an HSA with any health plan?
No. Only plans that meet the IRS high-deductible definition qualify: at least a $1,700 individual or $3,400 family deductible for 2026, with out-of-pocket maximums under $8,500 individual or $17,000 family.
