Why Did My ACA Health Insurance Premium Go Up in 2026?
If your renewal notice looks nothing like last year’s bill, you’re not alone — and it’s not a mistake. Two separate things happened at once for 2026: your plan’s list price went up, and for a lot of households, the subsidy that used to cover part of it shrank or disappeared. Here’s the short version of what changed and what to actually do about it.
The Short Answer
Two things stacked on top of each other this year:
- The sticker price of Marketplace plans rose sharply on its own — a weighted national average increase of roughly 26%, driven by rising hospital costs, GLP-1 drug utilization, and general medical trend.
- The enhanced premium tax credits that made Marketplace plans cheap since 2021 expired at the end of 2025 and Congress didn’t renew them, so subsidy calculations reverted to the older, less generous pre-2021 formula for 2026 coverage.
Combined, the average premium payment after subsidies rose from roughly $113 to $178 a month nationally — a 58% increase in what enrollees actually pay out of pocket, even though the underlying plan price only rose about 26%. The gap between those two numbers is the subsidy change, not just inflation in medical costs.
Three Reasons Your Specific Premium Jumped
1. Your subsidy shrank because of the expired enhancements
From 2021 through 2025, a temporary law capped everyone’s expected contribution at 8.5% of income and removed the old income ceiling on subsidies entirely. That law expired on schedule at the end of 2025. For 2026, subsidies are calculated using the original, less generous formula — which means smaller tax credits at every income level, and none at all above 400% of the federal poverty line.
2. The plan itself got more expensive, regardless of subsidies
Independent of the subsidy change, insurers raised their base rates by a weighted national average of about 26% for 2026 — driven by higher hospital and drug costs (GLP-1 medications in particular), and general medical inflation. This part of the increase would have happened even if the enhanced subsidies had been renewed.
3. Your household’s income or age bracket shifted
Even a modest raise, a new side income, or simply turning a year older can move your subsidy calculation. Premiums are age-rated (older enrollees pay more for the same plan), and subsidy amounts are recalculated every year against your current estimated income — so a renewal notice can reflect real changes in your own numbers, not just marketwide trends.
Don’t guess — check your actual number. Enter your income, age, and household size to see exactly what your 2026 subsidy and premium should be.
Run the subsidy calculator →What to Do About It
- Re-run your subsidy estimate. Don’t assume last year’s number still applies — the formula itself changed, not just the prices. The subsidy calculator gives you a current estimate for your exact household.
- Check if you’re near the subsidy cliff. If your income sits close to 400% of the federal poverty level, a small change in your Modified Adjusted Gross Income (like an extra 401(k) or HSA contribution) can restore your entire subsidy. See the full cliff breakdown for the exact income thresholds by household size.
- Actively re-shop instead of auto-renewing. Auto-renewal often re-enrolls you in a similar plan at its new price — it doesn’t automatically find you the cheapest option for 2026. Our plan comparison guide walks through checking other metal tiers and insurers before you accept a renewal.

Frequently Asked Questions
Is this increase a mistake or a billing error?
For most enrollees, no — it reflects a real, nationwide change in both plan pricing and subsidy rules for 2026. It’s still worth double-checking your renewal notice against a fresh subsidy estimate, since your specific number depends on your income, age, and plan.
Will my premium keep going up every year now?
Base premiums typically rise year over year regardless of subsidy policy, but the especially large jump in 2026 was driven specifically by the expiration of the enhanced subsidies on top of normal medical cost trend — not a permanent new rate of increase.
Can I switch plans mid-year if my new premium is too high?
Generally you’re limited to Open Enrollment or a qualifying life event to change plans, but you can always re-shop among available plans during your state’s enrollment window. Check our coverage terms glossary for how special enrollment periods work if your situation has changed.
Does everyone’s premium go up by the same amount?
No — the impact varies enormously by state, insurer, age, and especially by whether your income sits above or below 400% of the federal poverty level. Households right at that line see by far the largest swings.
The bottom line: your premium likely went up for two separate reasons at once — a real price increase on the plan itself, and a smaller (or vanished) subsidy now that the pandemic-era enhancements have expired. Re-running your actual numbers, rather than assuming your renewal notice is final, is the single most useful thing you can do before your next payment.
