A universal healthcare system in the United States would require between $1.5 trillion and $3.0 trillion in additional federal spending per year, depending on how it’s designed. That’s the Congressional Budget Office’s estimate for 2030 under a single-payer model based on Medicare. But that number doesn’t tell the whole story, because much of that new federal spending would replace what Americans already pay through insurance premiums, deductibles, and co-pays. The real question isn’t just what universal healthcare costs the government. It’s what it costs compared to the system we already have.
What Americans Already Spend on Healthcare
The U.S. spends more on healthcare than any other wealthy nation, and it’s not close. In 2024, health spending averaged $14,775 per person. That’s nearly double the $7,860 average across comparable high-income countries like Germany, Canada, Australia, and France. Even Switzerland, the next most expensive country, spent about $9,963 per person, roughly $5,000 less than the U.S.
Total national health spending is projected to grow at about 5.8 percent per year through 2033, outpacing economic growth of 4.3 percent. At that rate, healthcare will consume 20.3 percent of GDP by 2033, up from 17.6 percent in 2023. This means the baseline cost of doing nothing is itself enormous and accelerating. Any honest accounting of universal healthcare’s price tag has to be measured against this trajectory, not against zero.
The CBO’s Cost Range for Single-Payer
The Congressional Budget Office modeled five different versions of a single-payer system in 2022, each with different levels of coverage, cost-sharing, and provider payment rates. The results varied dramatically. Federal subsidies for healthcare would increase by $1.5 trillion to $3.0 trillion per year by 2030, depending on the design choices.
The low end of that range assumes the government pays healthcare providers at Medicare’s current rates, which are significantly lower than what private insurers pay. It also assumes some level of patient cost-sharing (co-pays and deductibles). The high end assumes more generous coverage with little or no cost-sharing and higher provider payment rates closer to what private insurance currently pays. The gap between $1.5 trillion and $3.0 trillion is essentially a set of political decisions about how generous the system would be and how aggressively it would control prices.
Critically, those trillions in new federal spending aren’t purely additional costs to the economy. They offset private spending that would disappear. Under any single-payer model, household insurance premiums would be eliminated entirely, and out-of-pocket costs would decline. Employers would stop paying for health insurance. The money shifts from private to public ledgers, though the total amount spent could go up or down depending on the system’s design.
Where the Savings Come From
Universal healthcare proponents point to several areas where a single-payer system could reduce overall spending. The most significant is administrative overhead. The U.S. healthcare system is uniquely complex. Hospitals and doctors’ offices employ massive billing departments to negotiate with dozens of private insurers, each with different rules, networks, and reimbursement rates. A single government payer would simplify this dramatically.
Prescription drug pricing is another major lever. Medicare’s recently gained authority to negotiate prices on just 10 drugs is projected to save $100 billion through 2031. A universal system negotiating prices across the entire pharmaceutical market would have far greater leverage. Countries with universal systems routinely pay 50 to 70 percent less for the same brand-name medications.
The CBO’s lower-cost models also achieve savings by paying providers at Medicare rates rather than private insurance rates. Private insurers typically pay hospitals and doctors considerably more than Medicare does for the same services. Shifting everyone to Medicare-level payments would reduce total healthcare spending but would also squeeze provider revenue, which is one of the most contentious design choices in the debate.
How It Would Be Funded
The most detailed funding proposal comes from Senator Bernie Sanders, whose Medicare for All plan outlines a mix of taxes designed to replace what households and employers currently spend on insurance. The core elements include a 7.5 percent payroll tax on employers (with the first $2 million in payroll exempt, shielding small businesses) and a 4 percent income-based premium on households. Because of the standard deduction, families of four earning less than $29,000 per year would pay nothing under the household premium.
Higher earners would face steeper income tax rates: 40 percent on income between $250,000 and $500,000, scaling up to 52 percent on income above $10 million. The plan also includes a 1 percent annual wealth tax on households with a net worth exceeding $21 million, affecting roughly the wealthiest 0.1 percent of Americans. Progressive estate tax rates would replace the current flat 40 percent rate, reaching 55 percent for estates over $50 million with an additional surtax on estates above $500 million.
For most working families, the math is straightforward: would the new taxes cost more or less than what you currently pay in premiums, deductibles, and co-pays? A family paying $15,000 a year for employer-sponsored insurance (a common figure for family coverage) would see that cost vanish, replaced by the 4 percent income-based premium. For a household earning $60,000, that premium would be roughly $1,240, a net savings of over $13,000. For higher-income households, the calculation shifts in the other direction.
Economic Effects Beyond the Price Tag
Universal healthcare would reshape the labor market in ways that don’t show up in simple cost projections. The CBO identified a significant reduction in “job lock,” the phenomenon where workers stay in jobs they’d otherwise leave because they depend on employer-provided insurance. Under the current system, people avoid switching jobs, starting businesses, going part-time, or retiring early because losing coverage is too risky.
Disconnecting health insurance from employment would lower the barrier to self-employment and entrepreneurship. Small businesses, which currently pay a higher percentage of payroll for health benefits than large corporations, would see that disadvantage eliminated. New businesses would no longer need to navigate the complex and costly process of selecting and providing health insurance. The CBO noted these effects could improve productivity and economic dynamism, though they’re difficult to quantify precisely.
There’s a counterbalancing effect, too. The CBO found that some workers would choose to work fewer hours, not because they’re less productive, but because eliminating premiums and out-of-pocket costs would effectively make them wealthier. They could maintain their standard of living with less paid work, freeing time for other priorities. Whether you view that as a benefit or a cost depends on your perspective.
Why Cost Estimates Vary So Widely
The $1.5 trillion to $3.0 trillion range from the CBO reflects genuine uncertainty, not sloppy math. Small design decisions create enormous differences at national scale. Setting provider reimbursement rates just 10 percent higher or lower can shift spending by hundreds of billions. Deciding whether to cover dental, vision, hearing, and long-term care (which most current proposals include) adds significant cost. Choosing how much patients pay out of pocket at the point of care changes both total spending and how much care people seek.
There’s also the question of utilization. When you remove financial barriers to care, people use more of it. The uninsured and underinsured would see doctors they’ve been avoiding. Preventive care visits would increase. Some of that new utilization would reduce costs over time by catching diseases earlier, but in the short term, it adds to the bill. The CBO’s models account for this increased demand, which is part of why even the lower estimates show substantial new federal spending.
Perhaps the most honest answer to “how much would universal healthcare cost” is that America already spends enough. At $14,775 per person, the U.S. spends nearly twice what other wealthy countries pay to cover everyone. The challenge isn’t finding new money. It’s reorganizing how existing money flows, deciding who pays, and accepting the tradeoffs that come with any system design.
