- While Premiums Soar Under Obamacare, Costs of Employer-Based Plans Are Stable The New York Times by Reed Abelson — In sharp contrast to the soaring health insurance premiums in many Affordable Care Act marketplaces, the cost of coverage for the vast numbers of people who get insurance through their jobs rose relatively little this year, continuing a period of remarkable stability in the employer market, according to a national survey released Tuesday. The annual premium for family coverage rose an average of 3 percent to $18,764 this year, according the Kaiser Family Foundation, a nonprofit group, which conducted the annual survey of employers. That is the sixth straight year that employer-provided policies have increased by well under 5 percent, according to the survey. Employers paid the bulk of the costs, the survey found, with workers shouldering an average of $5,714, a year for a family policy.
