How Much and Why ACA Marketplace Premiums Are Going Up in 2027 Print Email Copy Link Add KFF on GoogleNote: This brief was originally published on July 8 and updated on August 3, 2026 to include proposed 2027 rates from all 50 states and the District of Columbia.
ACA Marketplaces insurers are proposing a median premium increase of 15% in 2027, according to KFF’s updated analysis of 276 insurers with publicly available filings across all 50 states and the District of Columbia.
Last year’s median nationwide proposed rate change was 18%, and the median finalized rate change was 20%.
While this proposed rate change is lower than last year, it represents the second-highest requested rate change since 2018, as premium growth had been relatively flat in this market for several years.
Based on detailed filings from 16 states and DC, rising healthcare prices—as in prior years—remain the primary driver of 2027 premium increases.
