Did the Affordable Care Act Make Health Care More Affordable?

The expiration of the ACA’s enhanced premium tax credits at the start of 2026, combined with rising insurer premiums, put a spotlight on health care affordability that extends beyond Marketplace enrollees. KFF’s Cynthia Cox examines the ACA’s record and the broader underlying question it raises: what’s a fair price for Americans people to pay for health care?

The ACA MarketplaceS

In Preliminary Rate Filings, ACA Marketplace Insurers Largely Propose Double-Digit Premium Increase For 2027, Following a Steep Climb This Year 

ACA Marketplace insurers are proposing a median premium increase of 14% for 2027— indicating a likely second consecutive year of double-digit increases, according to a new analysis of preliminary rate filings in 16 states and DC. If these increases hold, typical premiums for insurers participating in the ACA Marketplaces would jump by more than one-third between 2025 and 2027.

The Average Marketplace Deductible Grew by About $1,000 Per Person in 2026, With More Enrollees Shifting to Higher-Deductible Plans as Enhanced Tax Credits Expired

The average Affordable Care Act (ACA) Marketplace deductible experienced the steepest increase in history—growing by 37% or over $1,000, from $2,759 in 2025 to $3,786 in 2026 as enhanced premium tax credits expired, according to a new KFF analysis. After the enhanced tax credits ended, many Marketplace shoppers shifted toward lower-premium, higher-deductible plans.
