The United States has the most expensive health care system in the world by a wide margin. In 2024, the U.S. spent 17.2% of its entire GDP on health, nearly double the OECD average of 9.3%. Germany, the next highest spender, allocated 12.3% of GDP to health care, leaving a gap of almost five percentage points between first and second place. No other country comes close to matching what Americans pay for medical care, whether measured per person, as a share of the economy, or in raw dollar totals.
How U.S. Spending Compares Globally
The scale of the difference is hard to overstate. About 15 OECD countries spend between 10% and 12% of their GDP on health care. Most Central and Eastern European nations, along with newer OECD members in Latin America, spend between 6% and 9%. Mexico and Turkey spend less than 6%. The U.S. sits alone at the top, separated from even the most generous European systems by a gap larger than the entire health budgets of some smaller countries.
Total U.S. health care spending reached roughly $5.5 trillion in 2024, growing at 8.2% that year alone. Projections from the Centers for Medicare and Medicaid Services estimate average annual growth of 5.8% through 2033, consistently outpacing expected GDP growth of 4.3%. In practical terms, health care is claiming a bigger slice of the American economy every year, with no sign of slowing down.
Where the Money Goes
Several factors drive U.S. costs far beyond what other wealthy countries pay, and none of them alone explains the gap. Together, they create a system where nearly every component costs more.
Prescription drugs: Brand-name drug prices in the U.S. are 422% of the combined average across 33 other OECD nations, according to an analysis by the U.S. Department of Health and Human Services using 2022 data. Even after accounting for the rebates that drug companies pay back to insurers and pharmacy benefit managers, American prices remain 308% of international levels. That means Americans routinely pay three to four times what people in comparable countries pay for the same medications.
Administrative overhead: The U.S. spends about 7.6% of total health expenditures on administration, compared to 3.8% on average in similar countries. That translates to $925 per person versus $245 per person, a difference of $680 annually just to process insurance claims, run government health programs, and manage insurer overhead. This figure doesn’t even include the administrative burden on hospitals and doctor’s offices themselves.
Physician salaries: American doctors earn significantly more than their counterparts abroad. The average U.S. physician earns about $316,000 per year. In Germany, the figure is $183,000. In the United Kingdom, it’s $138,000. In France, physicians average $98,000. Higher medical school debt, longer training periods, and a market-driven compensation structure all contribute to these differences.
Who Pays for It
Unlike most high-income countries, the U.S. splits health care funding almost evenly between public and private sources. In 2024, governments at all levels covered 48% of total health spending. The federal government alone accounted for 31% of the bill ($1.7 trillion), primarily through Medicare, Medicaid, and federal employee health benefits. State and local governments covered another 16%.
The remaining 52% came from private sources. Households bore the largest share at 28%, paying through insurance premiums, deductibles, copayments, and out-of-pocket costs. Private businesses contributed 18% through employer-sponsored insurance. Other private sponsors made up the final 6%. This mix means that even though the U.S. government spends enormous sums on health care, individual Americans and their employers still shoulder more than half the total cost.
High Spending, Middling Results
What makes U.S. health care spending especially striking is the disconnect between cost and outcomes. Americans do not live longer or healthier lives than people in countries spending far less. U.S. life expectancy consistently ranks in the bottom third of OECD nations, trailing countries like Japan, Switzerland, Spain, and Australia, all of which spend a fraction of what the U.S. does per person.
This gap shows up across many health measures. Infant mortality is higher in the U.S. than in most peer nations. Rates of preventable hospitalizations are higher. Access to primary care is more uneven. The system excels in certain areas, particularly advanced surgical procedures and cancer treatment survival rates, but those strengths don’t offset the broader pattern of paying more and getting less at a population level.
Why Other Countries Cost Less
Most countries with universal health care systems use some form of centralized price negotiation. Governments or designated agencies bargain directly with drug manufacturers, set fee schedules for hospital stays and doctor visits, and standardize billing. This eliminates much of the administrative complexity that inflates U.S. costs and gives buyers leverage to push prices down.
The structure of insurance also matters. Countries with single-payer systems or tightly regulated multi-payer systems (like Germany or the Netherlands) avoid the fragmented billing landscape that characterizes U.S. health care. When every hospital, clinic, and pharmacy deals with dozens of insurers, each with different rules, forms, and reimbursement rates, the administrative burden multiplies in ways that simply don’t exist elsewhere.
Physician compensation reflects broader economic choices as well. Many countries subsidize medical education heavily, which means doctors graduate with little or no debt and can accept lower salaries. In the U.S., the average medical school graduate carries over $200,000 in loans, creating pressure for higher compensation that ultimately gets passed along to patients and insurers.
The Trajectory Ahead
U.S. health spending is projected to keep growing faster than the overall economy for at least the next decade. After the 8.2% jump in 2024, growth is expected to ease to 7.1% in 2025, then average about 5.6% in 2026 and 2027 before settling around 5.3% annually through 2033. Even at those “slower” rates, health care’s share of GDP will continue climbing, meaning a larger portion of every dollar earned in America will flow into the medical system.
For individuals, this trend shows up as rising premiums, higher deductibles, and growing out-of-pocket costs. For employers, it means health benefits consume an increasing share of total compensation. And for governments at every level, it means health programs compete with education, infrastructure, and other priorities for limited budgets. The U.S. doesn’t just have the most expensive health care in the world today. It’s on track to widen the gap.
