The Cost Estimates Vary Widely Depending on the Plan Design

There is no single "Medicare for All" proposal, so there is no single price tag. Different versions would cost different amounts, cover different services, and shift costs between individuals, employers, and government in different ways. The estimates you see range from roughly $28 trillion to $40 trillion over ten years — a spread that reflects real disagreement about what the program would include and how it would work.

The most widely cited estimate comes from a 2018 University of Massachusetts study of Senator Bernie Sanders's proposal, which put the ten-year cost at $28.6 trillion. A 2021 Committee for a Responsible Federal Budget analysis of a similar proposal estimated $34 trillion over ten years. The Congressional Budget Office has not scored a full Medicare for All bill, so official government estimates do not exist. What matters for understanding the cost is knowing what drives these numbers: hospital and doctor payments, drug prices, administrative overhead, and what services are included.

Key Takeaways

  • Estimated costs range from $28 trillion to $40 trillion over ten years, depending on what services are covered and how much doctors and hospitals are paid.
  • The total cost is not the same as the tax increase — you would stop paying premiums, deductibles, and copays, which currently total hundreds of billions per year.
  • Different proposals would shift costs differently: some would raise income taxes, others would add a payroll tax, and some would use a combination.
  • Current U.S. healthcare spending is already around $4.5 trillion per year, so the question is whether a single-payer system would cost more or less than what Americans already pay.

How the Cost Estimates Are Built

The cost estimates start with what Americans currently spend on healthcare — roughly $4.5 trillion per year — and then adjust for what would change under a single-payer system. The main variables are payment rates to hospitals and doctors, the scope of covered services, and administrative costs.

Most Medicare for All proposals would pay doctors and hospitals at rates closer to what Medicare currently pays than what private insurance pays. Medicare rates are typically 20 to 40 percent lower than private insurance rates. If a proposal locks in Medicare rates across the entire system, that reduces total spending. However, some proposals would allow higher payments to rural hospitals or safety-net providers, which raises the cost back up.

The scope of coverage also matters. Some proposals cover dental, vision, and hearing aids; others do not. Some cover long-term care; others do not. Some proposals have no copays or deductibles; others have small ones. Each addition increases the cost. The UMass study assumed broad coverage with minimal cost-sharing, which is why its estimate is on the higher end.

The Difference Between Total Cost and What You Would Pay

The headline number — $28 trillion or $34 trillion — is the total amount the healthcare system would spend, not the amount individuals would pay in taxes. This is a critical distinction that often gets lost in debate.

Right now, Americans pay for healthcare through premiums (taken from paychecks), deductibles, copays, and out-of-pocket spending. Employers also pay premiums on behalf of workers. The total of all this — individual spending plus employer spending — is roughly $4.5 trillion per year. Under Medicare for All, you would stop paying premiums and copays, but you would pay a new tax instead.

The UMass study estimated that the new tax would be roughly 2.2 percent of income for employees and 8 percent of payroll for employers. A worker earning $50,000 per year would pay about $1,100 in new tax but would no longer pay premiums, deductibles, or copays. Whether that is a net gain or loss depends on what you currently pay out of pocket. Someone with low medical expenses might pay more; someone with high expenses might pay less.

How Different Proposals Would Fund the System

Funding mechanisms vary across proposals. Some rely primarily on income tax increases; others use payroll taxes, wealth taxes, or a combination. The funding method affects who bears the cost.

The Sanders proposal in the UMass study used a 2.2 percent employee payroll tax, an 8 percent employer payroll tax, a 4 percent income-based premium on households, and increased taxes on capital gains and high earners. A proposal from Senator Elizabeth Warren used a combination of employer payroll taxes, income-based premiums, and taxes on financial transactions and wealth. A proposal from Representative John Conyers relied more heavily on income tax increases and payroll taxes.

The choice of funding method matters because it determines who pays and how much. A payroll tax falls on workers and employers; an income tax increase falls on all income earners but can be structured progressively so higher earners pay more; a wealth tax falls on asset holders. No proposal has been enacted, so no actual funding mechanism has been tested.

Whether Medicare for All Would Cost More or Less Than Current Spending

This is where estimates diverge most sharply. Some analyses suggest Medicare for All would cost less than current spending because lower payment rates to providers and reduced administrative overhead would offset the cost of expanded coverage. Other analyses suggest it would cost more because expanded coverage and reduced cost-sharing would increase the amount of care people use.

The UMass study concluded that Medicare for All would cost slightly less than current spending over ten years — about $28.6 trillion versus a projected $34 trillion under the current system. However, this assumed that payment rates to providers would be set at Medicare levels and that administrative costs would drop sharply. If providers negotiated higher rates or if cost-sharing reductions led to significantly more healthcare use, the cost would be higher.

A 2019 analysis by the Committee for a Responsible Federal Budget suggested that a Medicare for All proposal similar to Sanders's would cost more than current spending — roughly $34 trillion versus $33 trillion under current law — because expanded coverage and reduced cost-sharing would increase utilization faster than lower payment rates would reduce costs. The difference between these analyses reflects genuine uncertainty about how providers and patients would respond to a new system.

What Happens to Current Healthcare Spending

Under Medicare for All, the money Americans and employers currently spend on healthcare would not disappear — it would be redirected into taxes that fund the new system. This is sometimes called "replacing premiums with taxes."

Currently, the average family with employer coverage pays roughly $7,000 per year in premiums (split between employee and employer contributions) plus out-of-pocket costs like deductibles and copays. Under most Medicare for All proposals, that $7,000 would be replaced by a new tax, though the tax might be higher or lower depending on income and the specific proposal. The advantage is that you would know the tax amount in advance and would not face surprise bills or deductibles. The disadvantage is that you would have less choice about how much to spend on healthcare.

Frequently Asked Questions

Would Medicare for All cost more than what Americans currently pay for healthcare?

It depends on the proposal and how you measure cost. Total healthcare spending might be similar to or slightly lower than current projections, but the distribution of who pays would change. Individuals would pay through taxes instead of premiums and copays, and employers would pay through payroll taxes instead of insurance premiums. Some people would pay more; others would pay less.

Why do cost estimates vary so much?

The estimates depend on assumptions about payment rates to doctors and hospitals, what services are covered, how much people would use healthcare if cost-sharing dropped, and administrative costs. Small changes in these assumptions produce large changes in the total cost over ten years.

Would the government have to raise taxes to pay for Medicare for All?

Yes, but the new taxes would replace current premiums and out-of-pocket spending. Whether your total payment goes up or down depends on your current healthcare costs and income. The government would collect the taxes and use them to pay providers directly instead of individuals and employers paying insurance companies.

Does the $28 trillion estimate include what people currently pay for healthcare?

No. The $28 trillion is the total amount the healthcare system would spend. Current spending is already around $4.5 trillion per year, or $45 trillion over ten years. The $28 trillion estimate assumes that lower payment rates and reduced administrative costs would bring total spending down compared to what it would be under current law.

What would happen to health insurance companies under Medicare for All?

Private health insurance as it currently exists would end. Insurance companies would no longer sell coverage for the services included in Medicare for All, though some might offer supplemental coverage for services not included in the program. This would eliminate the administrative costs of processing claims and determining coverage, which is one reason some analyses project lower total costs.
