Colorado residents who buy their own health insurance are bracing for another round of sticker shock in 2027, with premiums on the individual market set to rise by an average of 10%. That's on top of a punishing 22% increase that hit the same market this year, and it comes as financial-assistance recipients are expected to see their monthly costs climb by about $20 on average.
The projections come from the Colorado Division of Insurance, as reported by The Denver Post, which detailed how the 2027 increases will not land evenly across the state. Coloradans on the eastern plains can expect increases of roughly 6%, while those in the Grand Junction area face hikes closer to 16%. The disparity reflects how local market conditions and provider costs vary even within a single state's insurance pool.
Notably, the finalized 10% average is actually lower than what insurers initially wanted. Colorado insurers had requested larger premium increases before ultimately reducing those asks after the state legislature partially replaced expiring federal subsidies, according to the same Denver Post reporting. The state's rate reductions are projected to save consumers a combined $42.1 million, and Colorado's reinsurance program — which acts as a financial backstop for insurers covering customers who need unusually expensive care — is expected to shave nearly $470 million off premiums in 2027.
Why Colorado's Increase Undercuts the National Trend
Colorado's finalized 10% average increase looks relatively modest next to the national picture. Nationwide, insurers proposed a median premium increase of 15% for 2027, according to KFF, which also notes this marks the second consecutive year of double-digit premium hikes across ACA Marketplace plans. Last year's median nationwide proposed rate change was 18%, with a median finalized change of 20%, per the same KFF analysis.
Other states have seen a wide range of proposed increases heading into 2027. The Georgetown University Center on Health Insurance Reforms reported that early statewide average proposed increases ranged from 6.5% in Vermont to 22.4% in Washington. KFF also found that proposed premium changes nationally ranged from a 1% decrease to as much as a 54% increase, though most fell between 10% and 25%.
What's Driving the Costs Higher
Rising healthcare prices remain the primary driver behind the 2027 increases, KFF's analysis found, with insurers also pointing to general inflation and labor shortages. The underlying cost of medical care and prescription drugs — what insurers call the medical trend — saw a median projected increase of 10% for 2027, up from an average of 8% in each of the prior few years, according to the Peterson-KFF Health System Tracker.
Layered on top of rising medical costs is the expiration of enhanced pandemic-era subsidies at the end of 2025. Insurers frequently cited that expiration, along with a related increase in the risk pool's morbidity, as a key factor behind proposed 2027 rate hikes, per Georgetown's Center on Health Insurance Reforms. The federal government shutdown ended after a deal allowed those enhanced subsidies to lapse, and current subsidies now have a hard stop at four times the federal poverty line — about $132,000 for a family of four.
That subsidy cliff carries its own risk for the broader insurance pool. Healthier people may be more likely to drop coverage entirely when prices rise without enough financial help to offset them, leaving behind a smaller and costlier pool of remaining customers. The Peterson-KFF Health System Tracker found that the expiration of enhanced tax credits already contributed to enrollment declines in 2026, with healthier enrollees more likely to walk away from their plans. Georgetown's analysis projects the individual market could shrink by 17% to 26% this year, with implications that will continue to ripple into 2027 rates.
The Stakes for Millions of Enrollees
The numbers underscore how much is riding on these annual rate reviews. Roughly 19.2 million Americans were actively enrolled in ACA Marketplace health plans as of early 2026, according to NPR. For many of them, the difference between a proposed rate and a finalized one can mean real money each month — and Colorado regulators narrowed that gap by imposing lower 2027 rates, which are set to take effect next year.
