You’ve got maybe fifteen minutes between meetings to pick a health plan that’s going to follow you for the next twelve months. That’s the reality of open enrollment for most people, and it’s exactly why so many just click “keep my current plan” out of pure fatigue.
This year, that shortcut costs more than it used to. ACA marketplace insurers have proposed a median premium increase of about 15% for 2027, according to KFF’s analysis of rate filings across all 50 states, the second year in a row of double digit hikes. If you’re on an employer plan, your HR team is looking at similar numbers behind the scenes. Either way, the plan that made sense for you in 2026 might not be the best fit for 2027.
Why Open Enrollment 2027 Feels Different
Enhanced ACA premium tax credits expired in 2026, and KFF found that average monthly premium payments (what people actually pay after subsidies) jumped 58% that year, from about $113 to $178 a month. Insurers are now pricing 2027 plans against rising hospital, drug, and labor costs, part of why the median proposed increase sits near 15%, with approved rates still landing higher or lower state by state.
Dates matter too. Healthcare.gov open enrollment for 2027 coverage runs November 1 through December 15, 2026, shorter than the January 15 deadline from prior years. Miss it and you’re locked out unless you qualify for a special enrollment period. Employer open enrollment usually lands earlier, between September and November, so check your company’s calendar separately.
Start With Total Cost, Not the Premium
The number on the enrollment screen is just the monthly premium. It’s not what the plan will actually cost you over a year. The real math looks more like this:
Total cost = (premium x 12) + expected deductible spending + likely copays or coinsurance, capped by the plan’s out-of-pocket maximum.
A plan with a low premium and a $7,000 deductible can end up pricier than a plan with a higher premium and a $2,000 deductible, especially if you know you’ll see a doctor more than once or twice this year. Pull your claims history from last year if you can. It’s the best predictor of what next year will cost you, and it pairs well with a broader mid-year money moves check rather than treating insurance as its own isolated decision.
HDHP vs PPO: What Actually Fits Your Year
There’s no universally “better” option here. It depends on how much care you expect to use and whether you want to pair coverage with a Health Savings Account.
| HDHP (HSA-eligible) | PPO | |
|---|---|---|
| Monthly premium | Usually lower | Usually higher |
| Deductible | Higher, you pay more before coverage kicks in | Lower, coverage starts sooner |
| HSA eligible | Yes | No |
| Best fit | Light medical use, want to save pre-tax for future costs | Frequent doctor visits, ongoing prescriptions, want predictable copays |
| Network flexibility | Varies by plan | Often broader out-of-network coverage |
A quick rule of thumb: if you expect only a checkup or two, an HDHP paired with an HSA can leave you ahead even with a higher deductible, since the premium savings and tax-advantaged contributions often outweigh the risk. If you or a family member manage a chronic condition or see specialists regularly, a PPO’s lower deductible tends to win despite the higher monthly cost. Run both scenarios with your actual numbers, since the “right” answer changes household to household.
HSA vs FSA: The Difference That Costs People Money
These two get confused constantly, and mixing them up can cost you real money.
An HSA (Health Savings Account) only comes with an HDHP. Money rolls over year to year and it’s yours even if you switch jobs. For 2027 the IRS has set contribution limits at $4,500 for self-only coverage and $9,000 for family coverage, up from $4,400 and $8,750 in 2026, plus another $1,000 if you’re 55 or older.
An FSA (Flexible Spending Account) can pair with any plan type, but it’s largely “use it or lose it.” For 2026, the IRS capped health FSA contributions at $3,400, and most plans cap carryover at $680 into the next year, if a carryover is offered at all. Contribute too much in a light medical year and you can forfeit the difference.
These elections also change what comes out of your paycheck pre-tax, so if your income or family situation shifted this year, pair this decision with a look at how to adjust your tax withholding.
Check the Drug List and the Doctor Network Before You Compare Price
A cheap plan that doesn’t cover your prescription, or drops your regular doctor out of network, isn’t actually cheap. Before you compare premiums side by side:
- Pull the plan’s drug formulary and confirm your prescriptions are on it, and at what tier (tier 1 copays look nothing like tier 4 coinsurance).
- Search the plan’s provider directory for your doctors. Directories go stale, so a quick call to confirm they’re still in-network beats trusting the online list alone.
- Ask about out-of-network costs specifically. Some plans quietly shift a big share of cost to you the moment you step outside their network, which works a lot like the hidden charges covered in the FTC’s rules on junk fees, just buried in a benefits document instead of a receipt.
The Default Nobody Should Pick: Auto-Renewal
Doing nothing during open enrollment usually means you get auto-enrolled in a similar plan, often at a higher premium and sometimes with a different (and untested) network or formulary behind the scenes. Given this year’s rate hikes, auto-renewal is probably the most expensive choice available to you. It may still turn out fine, but you won’t know unless you actually compare.
A Worksheet You Can Actually Use
- Pull last year’s claims summary from your insurer’s portal or app.
- List every prescription and provider you used, and check each against the new plan’s formulary and network.
- Estimate a light, average, and heavy year of medical use, then run the total cost formula above for each scenario under every plan you’re weighing.
- Pick HDHP+HSA or PPO based on the scenario most likely for your household, not the one you hope for.
- If you’re eligible for a subsidy, rerun your numbers on healthcare.gov, since subsidy amounts shift with income and household size.
- Set a calendar reminder. For ACA plans, that’s December 15, 2026 for coverage starting January 1, 2027.
If medical costs still feel unmanageable once the new plan year starts, remember you can often negotiate medical bills after the fact, even with insurance in place.
Practical Takeaways
- Compare total cost, not the sticker price on the premium.
- HDHP+HSA tends to favor light medical use; PPO tends to favor frequent, predictable care.
- FSA money is largely use-it-or-lose-it; HSA money isn’t.
- Confirm your drugs and doctors are covered before you compare prices, not after you enroll.
- Mark your deadline. Auto-renewal is the most expensive plan by default this year.

Frequently Asked Questions
When does open enrollment start for 2027 coverage?
For ACA marketplace plans, healthcare.gov open enrollment for 2027 coverage runs from November 1 through December 15, 2026, a shorter window than in past years. Some state-run marketplaces may extend slightly further, but not past December 31, 2026. Employer open enrollment dates vary by company, typically between September and November.
What’s the real difference between an HDHP and a PPO?
An HDHP usually has a lower monthly premium but a higher deductible, and it’s the only plan type that qualifies you to contribute to an HSA. A PPO usually costs more per month but starts covering care sooner and often gives you more flexibility to see out-of-network providers.
Should I choose an HSA or an FSA?
It depends on which health plan you pick, since HSAs only pair with HDHPs. If you’re eligible for both, HSAs tend to be more flexible because unused funds roll over indefinitely and the account stays with you even if you change jobs. FSAs are mostly use-it-or-lose-it, so they fit better with predictable, recurring expenses.
Why are health insurance premiums going up so much for 2027?
KFF’s analysis of insurer rate filings found a median proposed increase of about 15% for 2027 ACA marketplace plans, the second straight year of double digit hikes. Insurers point to rising hospital, physician, and prescription drug costs, plus labor cost pressure. Proposed rates still need state regulator approval and can change before plans go live.
What happens if I don’t do anything during open enrollment?
In most cases you get automatically re-enrolled in a similar plan, often at a higher premium and sometimes with a different network or drug formulary than you’re used to. Given this year’s rate increases, comparing plans instead of relying on auto-renewal can matter more than usual.
