Nearly every developed nation pays for healthcare through some form of public funding, whether that’s general taxes, payroll deductions, or government-run insurance programs. The mechanisms vary widely, but the core idea is the same: spreading costs across a population so that medical care doesn’t bankrupt individuals at the point of service. The United States is the notable outlier, spending $14,775 per person annually while relying more heavily on private insurance and out-of-pocket costs than any other wealthy nation.
Four Models That Fund the World’s Healthcare
Healthcare systems around the world generally follow one of four funding models, though many countries blend elements of more than one.
In the Beveridge model, the government both pays for and provides healthcare, funded through general taxation. Care is free at the point of service. The United Kingdom, New Zealand, and Spain all use this approach. The UK spent £258 billion on government healthcare in 2024, with public funds covering 81.3% of all health spending in the country, up from 74% in 1997.
The Bismarck model uses nonprofit insurance funds financed through payroll deductions split between employers and employees. Germany, France, the Netherlands, Japan, and Switzerland all operate this way. In Germany, the sickness insurance contribution rate is 14.6% of gross wages, split evenly, plus an average supplementary contribution of 2.5%, also split evenly. That brings the total health insurance cost to roughly 8.55% of wages for both workers and employers.
The national health insurance model (sometimes called single-payer) has the government act as the sole insurer, collecting taxes and paying private or public providers. Canada and South Korea use this approach. In Canada, provinces generate about 78% of healthcare funding themselves, with the federal government providing the remaining 22% through the Canada Health Transfer.
The out-of-pocket model is what exists in most low- and middle-income countries where insurance coverage is minimal or nonexistent. Patients pay providers directly. Chad, India, and Rwanda are commonly cited examples, though many of these nations are working to build public systems.
How Much Countries Actually Spend
Per-capita healthcare spending in 2024, adjusted for purchasing power, shows dramatic differences even among wealthy nations:
- United States: $14,775
- Switzerland: $9,963
- Germany: $9,365
- Netherlands: $8,436
- Austria: $8,401
- Sweden: $7,871
- France: $7,367
- Canada: $7,301
The U.S. spends nearly 50% more per person than Switzerland, the second-highest spender. Most other wealthy countries cluster between $7,000 and $9,500. In 1980, these nations all spent between 4% and 8% of GDP on healthcare. By 2023, most had risen to between 8% and 12%, while the U.S. crossed 16%.
Spending More Doesn’t Mean Better Results
A 2024 Commonwealth Fund analysis of high-income countries found that Australia, the Netherlands, and the United Kingdom were the top three performers overall. The two highest-ranked countries, Australia and the Netherlands, also had the lowest healthcare spending as a share of GDP among the nations studied. The United States, despite spending far more than any other country, ranked last in overall performance.
Administrative efficiency is one area where spending patterns diverge sharply. Australia and the UK scored highest on measures like how much time doctors spend dealing with insurance claims, how much paperwork patients face, and how often billing disputes arise. Systems funded through taxation tend to have simpler billing because there’s one payer, not dozens of competing insurers each with different rules.
Taiwan’s Single-Payer System
Taiwan offers a useful case study of how the national health insurance model works in practice. The country runs a single government insurance program with a premium rate of 5.17% of income. For most private-sector employees, workers pay 30% of that premium, employers cover 60%, and the government picks up the remaining 10%. Low-income households and military conscripts pay nothing at all, with the government covering 100% of their premiums. The system achieves near-universal coverage while keeping administrative costs low.
What Patients Pay Out of Pocket
Even in countries with universal coverage, patients typically pay something at the point of care. Sweden illustrates how these costs are structured and capped. A primary care visit costs between $10 and $30 depending on the region. Specialist visits can run up to $40. Hospital stays cost about $14 per day. But total out-of-pocket spending on outpatient care is capped at roughly $153 over any 12-month period, and prescription drug costs are capped at about $400 per year. Once you hit those limits, care is free for the rest of the year.
This pattern of small co-payments with hard annual caps is common across European systems. The co-payments discourage unnecessary visits while the caps ensure that people with chronic conditions or serious illness aren’t financially devastated. It’s a fundamentally different approach from the U.S., where a single hospitalization can produce a five- or six-figure bill even for insured patients.
Countries With Constitutional Spending Requirements
Some nations go further than simply funding healthcare through legislation. Brazil’s constitution requires that health spending be at least 15% of net current revenue. The country operates the Unified Health System (known as SUS), which provides universal coverage funded by federal, state, and municipal taxes. Constitutional mandates like this make healthcare funding harder to cut during economic downturns, since reducing spending below the threshold would require amending the constitution itself.
Hybrid Systems and Mandatory Savings
Singapore takes a different approach from any of the four standard models. The government requires workers to contribute to individual health savings accounts called MediSave, which can be used to pay for hospitalization, certain outpatient treatments, and health insurance premiums. A public insurance program called MediShield Life covers large hospital bills and expensive treatments, with premiums drawn directly from MediSave balances. The government also heavily subsidizes care at public hospitals. It’s a system built around personal responsibility backed by public safety nets, keeping total spending low while maintaining strong health outcomes.
What Universal Systems Typically Don’t Cover
Most publicly funded systems exclude certain categories of care. Dental work, routine vision care, and long-term custodial care are the most common gaps. Canada’s public insurance, for example, does not cover dental care for most adults. The UK’s NHS charges for dental visits on a tiered fee schedule. Even U.S. Medicare, which functions as a single-payer system for Americans over 65, excludes routine dental checkups, cleanings, fillings, dentures, and regular eye exams by law.
Long-term care, meaning ongoing help with daily activities like bathing, dressing, and eating, is excluded from most public health systems because it falls outside the traditional definition of medical treatment. Countries handle this gap differently. Some, like Germany, fund long-term care through a separate mandatory insurance program (the German long-term care contribution rate is 3.6% of wages). Others leave it to private insurance or family resources. It remains one of the largest unresolved financial risks for aging populations worldwide.
