KFF Video Examines What Insurers' Premium Cut Buys

Every health insurance premium dollar includes a slice that pays for insurer overhead and profit rather than medical care, and a new KFF video published September 10, 2026 breaks down how large that slice is and how it compares across private insurance and Medicare. KFF, formally the Kaiser Family Foundation, is a nonprofit organization known for independent health policy research, journalism, and polling. The video is hosted by Larry Levitt, KFF's executive vice president for health policy, and is the second installment in a three-part series on health insurance economics.

According to KFF's own description, the video compares administrative costs and profit margins across private insurance markets and Medicare, then considers what a Medicare-for-all system, meaning a government-run single-payer program, would resolve about that spending and what would likely remain unresolved. The supplied source material does not include specific dollar figures or percentages from the video itself, so this analysis focuses on the policy framework the video raises rather than restating numbers that were not provided. You can view KFF's full video analysis here.

Importantly, KFF frames this as a value question rather than an accusation of wrongdoing: the point isn't whether insurers profit, since that is expected in a regulated market, but whether policyholders receive commensurate value in benefits and service for the administrative share insurers retain.

Federal Rules Already Cap What Insurers Can Keep

Federal law already limits how much of a premium dollar insurers can retain for overhead and profit, through a regulation known as the medical loss ratio, or MLR. Under the Affordable Care Act, individual and small group marketplace plans must maintain at least an 80 percent MLR, meaning at least 80 cents of every premium dollar must go toward medical claims and quality improvement activities, with insurers required to issue rebates when they fall short. Large group plans and Medicare Advantage plans, which are private Medicare plans also called Medicare Part C, face an 85 percent MLR requirement under Centers for Medicare and Medicaid Services (CMS) rules. Medicare Advantage plans that miss that threshold for multiple consecutive years can face CMS enrollment sanctions or contract termination.

Traditional Medicare, the government-administered program covering Part A hospital and Part B medical benefits, is often cited by health policy researchers as carrying lower administrative overhead than private insurance, largely because it does not need to fund marketing, underwriting, or investor returns. However, the comparison is not perfectly apples-to-apples, since traditional Medicare's reported administrative costs are calculated differently and some functions, such as fraud prevention and program integrity, are handled by other federal agencies rather than counted directly against the program.

This is the tension KFF's series appears to be probing: a Medicare-for-all system would eliminate private insurer profit margins and much of the overhead tied to marketing and plan variation, but that alone would not automatically resolve every administrative cost, including the expense of managing provider networks, processing claims at scale, and preventing fraud in a much larger single program.

Key Takeaway

CMS already limits what Medicare Advantage insurers can keep for overhead and profit to 15 percent of premium revenue, through the 85 percent medical loss ratio requirement. The more useful question for beneficiaries comparing plans in 2026 isn't the size of that cut, it's whether a specific plan converts its spending into benefits, provider access, and service quality that actually match your needs.

What This Means for Your Medicare Enrollment Choices

This debate over insurer overhead has practical relevance for anyone comparing Medicare Advantage plans, because plan finances shape the extra benefits insurers can afford to offer beyond what traditional Medicare covers, such as reduced premiums, dental, vision, hearing, or over-the-counter allowances. A plan that operates efficiently and stays comfortably under the 85 percent MLR floor generally has more financial room to compete on extras, while a plan running close to that threshold has less cushion.

A few practical steps for readers as you compare 2027 coverage this fall:

Compare Medicare Advantage plans on the actual value of included benefits and provider networks, not just the premium, since MLR compliance is an aggregate financial requirement and does not by itself tell you how a specific plan will perform in your area.

If you're considering traditional Medicare paired with a Medicare Supplement, also called Medigap, and a standalone Part D prescription drug plan, know that Medigap insurers are typically held to their own state-based loss ratio standards, which shifts the overhead conversation to a different set of insurers and rules.

Review CMS Star Ratings, a federal quality scoring system updated annually, alongside benefit details, since a plan's efficiency and its quality of care are related but separate measures of value.

Medicare's Annual Enrollment Period runs October 15 through December 7, 2026, giving current beneficiaries a window to switch Medicare Advantage or Part D plans for the coming year. Because aggregate MLR and profit figures don't reveal how a particular plan performs for members in your specific area, it's worth reviewing your options with a licensed insurance agent who can walk through plan documents and local provider networks with you.

The broader question KFF's series raises, whether a Medicare-for-all system would deliver better value than the current mixed private-public model, is a legislative and policy debate well beyond any single enrollment decision. But the underlying issue, understanding how much of your premium funds care versus overhead, is directly useful as you evaluate your options this fall.
