ACA insurers are pitching a median rate increase of 15% for 2027, the second year in a row of double-digit premium hikes, according to a July 8 Peterson-KFF Health System Tracker analysis that was updated Aug. 3, offering an early look at the scale of the ACA premium increase 2027 enrollees may face.
How This ACA Premium Increase 2027 Analysis Was Conducted
The tracker reviewed 276 insurers in marketplaces across the country with publicly filed rates. The tracker’s analysis considered an insurer’s premium increase as the enrollment-weighted average rate change across its offerings in a state. While rates will be finalized in late summer, these filings provide a glimpse of the year ahead.
What’s Driving Rising Medical Costs Behind This Increase
Insurers cited steeper healthcare costs as informing rates. Looking at a subset of insurers, the median medical trend was 10% for 2027. Insurers mentioned inflation, labor supply issues, claims severity, GLP-1s, provider consolidation and No Surprises Act disputes as drivers.
Federal Policy Shifts Behind This ACA Premium Increase 2027
Federal policy shifts were also factors. Insurers more specifically attributed rising rates to the expiration of enhanced premium tax credits and greater morbidity in risk pools. As the expiration prompted an enrollment dip, healthier enrollees were more likely to let go of coverage. After subsidies, premium payments increased 58% on average in 2026.
The Role of Regulatory Changes and HR 1
Along with the expiration, regulatory changes and HR 1 played a role, insurers said. This combination of subsidy expiration and broader regulatory shifts suggests insurers are pricing in multiple compounding pressures simultaneously rather than a single isolated policy change.
The Range of Proposed Rate Changes Within This ACA Premium Increase 2027 Data
Overall, suggested premium changes for 2027 ranged from -1% to 54%, with most between 10% and 25%. Only one insurer proposed a decrease. This wide range, spanning from a slight decrease to more than a 50% increase, illustrates how unevenly the underlying cost and policy pressures are affecting individual insurers depending on their specific markets and risk pools.
Insurers Requesting the Steepest Increases
Fifty-one of the 276 insurers requested premium increases surpassing 25%, representing roughly one in five insurers in the analysis proposing hikes well above the overall median.
How This ACA Premium Increase 2027 Compares to Last Year
For 2026, the median nationwide proposed rate change was 18%. The median finalized rate change was 20%. Notably, finalized rates for 2026 ended up higher than what was initially proposed, suggesting insurers may again see their final 2027 rates increase beyond this current 15% median proposal once the review and approval process concludes in late summer.
Why the Gap Between Proposed and Finalized Rates Matters
Given that 2026’s finalized median rate change of 20% exceeded its own proposed median of 18%, enrollees and industry observers should treat this 15% figure for 2027 as a preliminary benchmark rather than a firm prediction, since historical precedent suggests the final number could climb higher.
What This ACA Premium Increase 2027 Means for Enrollees
With insurers citing a combination of rising medical costs, the expiration of enhanced premium tax credits, and regulatory changes as drivers, this second consecutive year of double-digit proposed increases suggests marketplace enrollees should prepare for continued affordability pressure heading into 2027. Given that 51 insurers have already proposed increases exceeding 25%, the practical impact of this ACA premium increase 2027 will likely vary significantly by state and specific insurer, making it important for enrollees to review their own plan’s finalized rate once available rather than relying solely on the national median.
What to Watch Going Forward
As rates move toward finalization in late summer, industry observers will likely watch whether the pattern from 2026, where finalized rates ended up higher than initially proposed, repeats itself for 2027. Given the combination of factors insurers have cited, rising medical trend, subsidy expiration, and regulatory changes tied to HR 1, this ACA premium increase 2027 may continue drawing scrutiny from policymakers and consumer advocates as the finalization process unfolds over the coming weeks.
