Health insurers offering Affordable Care Act (ACA) Marketplace plans have proposed a median premium increase of 15% for 2027, based on rate filings analyzed by KFF. The analysis reviewed filings from 276 insurers across all 50 states and Washington, D.C.
The proposed increase does not mean every consumer will pay 15% more, as final premiums will depend on insurer approvals, plan selection, location, and available financial assistance.
ACA Marketplace Premiums Could Increase Again in 2027
The proposed 15% median increase would mark the second consecutive year of double-digit premium growth in the ACA Marketplace.
According to KFF, insurers proposed an 18% median increase for 2026, while the final approved increase was 20%. If the 2027 proposals remain close to current filings, typical ACA Marketplace premiums would have increased by more than one-third over a two-year period.
The proposed changes vary significantly between insurers, with some requesting smaller increases while others seeking much higher adjustments.
How Large Are the Proposed Rate Increases?
Most insurers are requesting increases between 10% and 25% for 2027.
KFF found that:
- Around 63% of proposed rate changes fall within the 10% to 25% range.
- The largest group of insurers proposed increases between 10% and 15%.
- 51 insurers requested premium increases of 25% or more.
- Proposed changes range from a small decrease to increases above 50%.
These filings are still under review, and final 2027 ACA Marketplace rates will be decided after state regulators complete the approval process.
Why Are ACA Premiums Rising in 2027?
The biggest factor behind higher premiums is the increasing cost of healthcare services.
Insurers reported that medical care and prescription drug costs continue to rise, increasing the amount they pay for claims. KFF noted that insurers’ filings showed a median increase of about 10% in underlying medical and pharmacy costs.
Higher hospital expenses, physician services, and medication costs all contribute to higher insurance premiums.
Increased Healthcare Use and Higher Claims Costs
Some insurers also pointed to higher healthcare utilization as a reason for premium increases.
More frequent medical visits, increased use of specialty care, outpatient procedures, and higher-cost treatments can increase overall claims spending. When insurers pay more in claims, those costs are often reflected in future premiums.
Growing Demand for GLP-1 Medications
The rising use of GLP-1 medications has also become a factor affecting healthcare costs.
As demand increases for weight management and diabetes-related treatments, insurers are considering the impact of these medications on future healthcare spending.
Policy and Economic Changes
Insurers also cited broader economic factors and healthcare policy changes as contributors to rising premiums.
Factors mentioned in filings include inflation-related cost pressures, changes in federal policies, and adjustments affecting ACA Marketplace coverage.
Will Everyone Pay 15% More for ACA Insurance?
No. The 15% figure represents the median proposed increase across insurers, not an exact increase for every person.
A consumer’s final premium change can depend on:
- Location and state regulations
- Insurance company and selected plan
- Age and household details
- Changes in available subsidies
- Final approved rates
Some people may see smaller increases, while others could face higher changes depending on their circumstances.
When Will 2027 ACA Premium Rates Be Final?
The current rate filings are preliminary. State regulators will review insurer proposals before final premiums are approved.
Final ACA Marketplace rates are expected later in 2026 before the 2027 enrollment period begins.
Until approvals are complete, consumers should consider these numbers as early estimates rather than final prices.
The Bottom Line
ACA Marketplace insurers are proposing a median 15% premium increase for 2027, marking another year of significant rate growth.
The main reasons behind the increase include higher medical costs, rising prescription spending, increased healthcare utilization, and broader economic pressures.
However, the final impact on consumers will vary because approved rates, plan choices, and financial assistance programs will determine what individuals actually pay.
