What percentage of private health care insurance costs are sales and administrative
Executive summary
Estimates vary because analysts measure different things: private insurers’ overhead (administration + profits) is commonly reported around 11–18% of premiums for employer and individual markets, while broader studies that include billing-and-insurance (BIR) costs across insurers, providers and other actors place U.S. administrative spending at roughly 15–34% of total health spending (the Annals/Time figure of 34.2% is frequently cited) [1] [2] [3]. Which percentage applies depends on whether you ask “what share of premiums insurers spend on admin/profits” or “what share of total national health expenditures is administrative” [1] [4].
1. What people commonly mean — insurer-level “administration and profits”
When commentators cite a single number for private insurance administrative costs they usually mean the share of premium dollars insurers spend on operating costs and profits (the insurer overhead or “non‑benefit” share). Sources show a range: the Congressional Budget Office reported about 11% for large-group markets, 16% for small-group, and ~20% for nongroup plans; other summaries and CMS-derived figures commonly place private insurers’ overhead near 12.3% or in the 12–18% band [1] [5]. Industry groups sometimes report a higher operating-cost share — America’s Health Insurance Plans reported 17.8 cents per premium dollar to operating costs — while consultancies stress small margins (e.g., average insurer profit margins ~2.35% within total admin figures) [1] [6].
2. Systemwide measures — “administration” across the whole health sector
Other studies expand the definition beyond insurer overhead to include billing-and-insurance-related (BIR) tasks performed by hospitals, physician offices, nursing homes and insurers, plus non‑BIR business overhead. Those systemwide estimates are much higher: a prominent 2017 Annals of Internal Medicine analysis estimated U.S. insurers and providers spent $812 billion on administration in 2017—about 34.2% of national health expenditures—versus ~17% in Canada [2] [3]. Health Affairs and National Academy syntheses typically place administrative spending in the 15–30% range depending on inclusion criteria [4].
3. Why the ranges differ — apples vs. oranges in definitions and denominators
Disagreement stems from two measurement choices: numerator (what counts as “administrative”) and denominator (premiums, insurer revenues, or total national health expenditures). Comparing Medicare’s low percentage to private insurers’ can be misleading because Medicare serves sicker, costlier populations so the same absolute admin spending is a smaller share of larger benefit payments (a point raised by critics and defenders alike) [7] [8]. The Heritage Foundation and AJMC pieces highlight how differences in populations and accounting produce diverging ratios [7] [8].
4. How much is “excess” or wasteful admin?
Analysts trying to isolate “excess” administrative waste (the portion above plausible benchmarks) use cross‑country comparisons and microcosting studies. The Center for American Progress and National Academy syntheses estimate substantial excess BIR costs—hundreds of billions annually—attributing much of the gap to the multi‑payer private insurance model [9] [5]. But there is debate about how much of administration is productive — e.g., prior authorization, quality assurance, fraud prevention — and whether lower admin would automatically cut total spending [1] [9].
5. What the headlines usually omit
Media summaries often collapse these metrics into a single dramatic percentage (e.g., “34% of spending is administrative”) without clarifying whether that figure covers insurer overhead only or systemwide BIR and non‑BIR costs, or whether profits are included [3] [2]. Some advocacy groups extrapolate systemwide savings from eliminating private insurance; other commentators caution those extrapolations rest on contested assumptions about provider prices, transition costs, and which admin functions would remain [10] [7].
6. Bottom line for readers
If you ask “what share of premium dollars do private insurers spend on administration and profits?” use the insurer‑overhead figures: roughly 11–20% depending on market (large employer vs. small group vs. individual) and data source [1] [5]. If you ask “what share of total U.S. health spending is administrative across insurers and providers?” estimates cluster from about 15% up to the 34% figure from the 2017 Annals study — the higher number arises when counting broad BIR and other non‑clinical overhead across the whole system [2] [4]. Available sources do not mention a single universally accepted percentage because measurement choices drive the result.
