Most household budgets have a blind spot, and it isn't groceries or the electric bill — you feel those every week. It's the health insurance premium: a big, fixed number that most people set once, auto-renew, and never revisit until it's already been withdrawn. That worked when the Marketplace was cheap. It stopped working the moment the enhanced premium tax credits expired at the end of 2025. Out-of-pocket premiums for people who buy their own coverage jumped 58% on average in 2026, and insurers have now filed for another median increase of about 15% for 2027. The good news is that the size of your 2027 bill is not fixed yet — it depends heavily on choices you make during the open-enrollment window that opens November 1. This is a practical playbook for making those choices count, and for putting the new number into your budget before it surprises you in January.
First, the numbers you're actually up against
Across 276 insurers in all 50 states and Washington, D.C., the median proposed rate increase for individual-market plans in 2027 is about 15%. The proposals range from a 1% cut to a 54% increase, but the middle of the pack is unambiguous: 63% of insurers asked for increases between 10% and 25%. That comes on top of a brutal 2026, when finalized rate increases ran a median of roughly 20% and the expiration of the enhanced tax credits pushed the average enrollee's out-of-pocket premium up 58%.
Insurers point to two drivers. The underlying cost of medical care is running about 10% for 2027, up from an 8%-a-year historical norm, and the risk pool is deteriorating as healthier people drop coverage they can no longer afford — an effect actuaries are pricing in at roughly 4% to 8% on its own. In plain terms: prices rise, some healthy people leave, and their exit pushes prices up further for everyone who stays.
Make it concrete. Take a 40-year-old in Indianapolis earning $65,000 a year. In 2025, with enhanced credits, the monthly payment for a benchmark plan was about $316. In 2026 it jumped to $477. For 2027 it's projected at $546. That's an extra $158 a month — nearly $1,900 a year — for the same person buying the same tier of coverage, a 41% climb in 24 months.
Why this hits some households far harder than others
Here's the part that decides whether you feel a bruise or a body blow: subsidies. About 87% of Marketplace enrollees received a premium subsidy in 2026, and because subsidies are pegged to the cost of a benchmark plan, they rise as premiums rise. If you qualify, a chunk of that 15% increase is absorbed for you automatically — which is exactly why re-shopping matters, since the benchmark plan your subsidy is tied to can change from year to year.
The households getting hit hardest are the ones just over the line. The old 'subsidy cliff' is back in full force for 2027: earn even one dollar above 400% of the federal poverty level and your premium tax credit drops to zero. The damage is already visible — sign-ups among people earning 400% to 500% of poverty fell 44% from 2025 to 2026, a drop of more than 321,000 people who largely decided the unsubsidized price wasn't worth it.
Your 2027 open-enrollment playbook
- Do NOT auto-renew. This is the single most expensive default in personal finance right now. More than 20 states are seeing insurers exit for 2027, and hundreds of thousands of enrollees face plan terminations or re-mapping to a costlier default. Log in, compare every plan available in your ZIP code, and re-pick deliberately — even if you loved last year's plan.
- Mark the calendar. Open enrollment opens November 1, 2026. In most states you must enroll by mid-December for coverage that starts January 1, so treat early-to-mid November as your action window, not late December.
- Update your income estimate carefully. Your subsidy is based on your projected 2027 income. Estimate it as accurately as you can — lowball it and you'll owe money back at tax time; overshoot past 400% of poverty and you can lose the subsidy entirely.
- If you're near the cliff, work the MAGI, not just the premium. Pre-tax contributions to a traditional 401(k), a traditional IRA, or an HSA lower the modified adjusted gross income the subsidy is measured against. For a household hovering just above 400% of poverty, shifting a few thousand dollars into those accounts can pull you back under the line and unlock thousands in credits.
- Price the HSA-eligible route. If you're mostly healthy, a high-deductible plan paired with a Health Savings Account can beat a pricier low-deductible plan on total cost. The 2027 HSA contribution limits rose to $4,500 for individual coverage and $9,000 for family coverage, and those dollars are triple-tax-advantaged — deductible going in, growing tax-free, and untaxed coming out for medical costs.
- Check for a state-specific lifeline. States are patching the gap unevenly. Rhode Island set aside $19 million for state-funded subsidies, Virginia launched a Premium Savings program, and Oregon moved to its own Explore Health platform. What's available depends entirely on where you live, so check your state exchange, not just HealthCare.gov.
Watch the deductible and the out-of-pocket max, not just the premium
A lower monthly premium can be a false economy if it comes with a deductible you'll actually hit. For 2027, the maximum allowable out-of-pocket cap rose to $12,000 for an individual, up from $10,600 in 2026 — meaning a worst-case medical year can now cost you $1,400 more before insurance covers everything. When you compare plans, add the annual premium to a realistic estimate of your out-of-pocket spending, then compare those totals. The cheapest sticker price and the cheapest actual year are frequently not the same plan.
This is also where your budget math has to change. A premium is a fixed monthly cost you can plan for; the deductible is a variable cost you should be reserving for. If you pick a high-deductible plan to save on premiums, the responsible move is to route the savings into an HSA or an emergency buffer so a February hospital visit doesn't become a credit-card balance.
Fold the new number into your budget now
The subsidy cliff is a dollar cliff, not a gentle slope: one dollar of extra income above 400% of the federal poverty level can erase your entire premium tax credit and cost you thousands. Before you finalize enrollment, run your projected 2027 income against that threshold — and if you're just over it, ask whether a pre-tax 401(k), traditional IRA, or HSA contribution can bring your MAGI back under the line. It's one of the few places where saving more money literally saves you more money twice.
Health insurance is the rare budget line where doing nothing is a decision — and in 2027 it's an expensive one. Premiums are rising a median 15% on top of last year's 58% jump in out-of-pocket costs, insurers are leaving more than 20 states, and the plan you were auto-renewed into may not even exist next year. But the flip side is real leverage: because subsidies move with the benchmark and depend on your income, the window between November 1 and mid-December is when you actually set your 2027 cost. Re-shop instead of renewing, estimate your income with the subsidy cliff in mind, price the HSA route, and compare plans on total cost — premium plus likely out-of-pocket — not the monthly sticker alone. Then take whatever number you land on and put it in your budget as a fixed line today, so the January statement is something you planned for instead of something that knocks the rest of your month sideways. Run your new premium through a monthly budget to see exactly what it displaces before you commit.
