Every time a health insurance premium is paid, a portion of that dollar is immediately carved out before a single doctor’s visit is covered or a prescription is filled. That cut goes toward overhead, administrative expenses, and profit. While the existence of profit in the health insurance sector is a fundamental feature of the industry, a broader and more persistent debate centers on whether consumers are receiving adequate value in return for these substantial expenditures.
To unpack this complex dynamic, Larry Levitt, Executive Vice President for Health Policy at KFF, has broken down how administrative costs and profits vary across different sectors of the private insurance market and public programs like Medicare. His analysis also considers how a government-operated system, such as Medicare-for-All, might address these financial outflows, alongside the deeper structural challenges that would remain unresolved even if private insurers were removed from the equation entirely.
Understanding the Cost of Doing Business
Insurers siphon off billions of premium dollars annually to manage their operations, pay executive compensation, process claims, and secure profit margins. According to KFF data, these overhead and profit costs vary significantly depending on the market segment. On a per-enrollee basis, administrative costs and profits average $846 annually in the employer-sponsored insurance market, climb to $987 in the individual insurance market, and spike to $1,655 in Medicare Advantage plans.
When looking strictly at profit margins on paper, health insurers often appear to operate on modest terms. Typically, profit accounts for no more than a few percentage points of total premium revenues. However, health insurance operates on a massive financial scale, meaning that a few percentage points of an extraordinarily large revenue stream translates into a massive accumulation of capital.
The financial scale of the industry is highlighted by the performance of the seven largest publicly-held health insurance companies. Together, these corporate giants pulled in an estimated $71 billion in total profits in 2024. This figure encompasses revenue generated across their diverse business portfolios, including subsidiaries such as pharmacy benefit managers that control drug pricing and distribution.
Contrasting Private Insurance With Public Administration
The flow of health care dollars looks remarkably different depending on the specific program structure through which coverage is provided. In Medicare Advantage—the private insurance alternative that now covers more than half of all Medicare beneficiaries—approximately 90 cents of every premium dollar goes directly toward medical care. The remaining 10 cents is absorbed by overhead, administrative expenses, and corporate profit.

By contrast, traditional government-run Medicare operates with a radically different financial profile. Less than two cents of every dollar spent in traditional Medicare goes toward administrative costs. Furthermore, because it is structured as a public program rather than a commercial enterprise, traditional Medicare generates no profit.
The underlying mechanics driving this discrepancy are twofold. First, traditional Medicare is administered directly by the government rather than through a network of competing private insurance companies, eliminating the layer of corporate overhead and marketing expenses inherent to the private sector. Second, in traditional Medicare, the government sets prices for hospitals and physicians directly through standardized schedules, bypassing the complex, resource-intensive price negotiations that private insurers must conduct with individual health care providers.
Evaluating the Medicare-for-All Alternative
The stark differences in administrative overhead between public and private systems frequently fuel policy debates over systemic reform. Taking health insurance companies completely out of the equation—such as through the implementation of a single-payer, Medicare-for-All system operated by the government—would inherently reduce the capital siphoned off by administrative expenses and corporate profits.
However, policy experts caution that eliminating private insurers would not solve the primary cost drivers that plague the American health care system. The most significant factors driving the continuous growth of national health spending include high hospital prices, medical care that is not always grounded in rigorous clinical evidence, and the escalating costs of new prescription drugs and advanced medical technologies. These systemic financial pressures would persist under a government-run model and would still need to be addressed through regulatory price controls, utilization management, or other policy mechanisms.
Ultimately, the persistent debate over health insurance overhead forces a fundamental reckoning with how the health care system is organized. While consumers often begin by asking what tangible value private insurers provide for their financial cut, the broader and more difficult question may center on governance. Specifically, society must decide whom to trust with the ultimate authority to determine what health care services get covered, how medical providers are compensated, and how finite resources are distributed.
