The US spent $5.3 trillion on healthcare in 2024. That works out to $15,474 for every person and 18% of gross domestic product (GDP). Federal actuaries estimate spending will approach $9 trillion by 2034 or 20.6% of GDP.

Reading the national P&L

GDP is not literally a profit and loss statement, but the frame is useful. However anyone who has managed a budget will recognize the problem: when one expense consistently grows faster than the resources available to pay for it, everything else gets squeezed.

Healthcare’s bill is spread across enough accounts that few people see its full size. In 2024, the federal government financed roughly 31% of national health spending. Households financed 28%, private businesses 18%, and state and local governments 16%, with other private sources covering the remainder.

You encounter pieces of that bill as payroll deductions, taxes, copays, and insurance premiums. Your employer encounters another piece when deciding how much it can spend on compensation. Governments encounter it when allocating money among healthcare and other priorities.

Moving an expense from a patient to an insurer, or from an employer to the government, can make an enormous difference to the person paying it. It does not, by itself, reduce the national bill.

How a small gap becomes a takeover

From 2025 through 2034, national health spending is projected to grow by an average of 5.4% a year, compared with 4.1% for GDP. That seemingly modest gap pushes healthcare from 18% of the economy in 2024 to 20.6% in 2034.

A larger bill does not necessarily mean more people have coverage. In the same projections, the insured share of the population falls from 91.8% in 2024 to 90.5% in 2034. The country is expected to devote a larger share of its resources to healthcare while leaving a larger share of its population uninsured.

What makes the bill grow

Healthcare spending reflects both what care costs and how much care people receive. More spending can mean higher prices, more patients, more treatment per patient, or a shift toward more expensive treatments.

Those distinctions matter. A new therapy that gives someone another decade of healthy life and an unnecessary procedure both increase spending. Their value is very different.

Demographics also change the bill. Medicare is projected to grow faster than the other major payers through 2034. Federal actuaries point to the continued enrollment of baby boomers and the oldest members of that generation reaching ages when healthcare use typically rises.

A rising healthcare share of GDP therefore cannot tell us, on its own, whether Americans are getting sicker, receiving better care, or paying more for the same care. Within that complicated picture, chronic metabolic disease represents a substantial burden.

The metabolic line inside the line

The American Diabetes Association estimated that diagnosed diabetes accounted for $306.6 billion in attributable medical costs in 2022. Across the spending categories it analyzed, roughly 25% of healthcare dollars went toward care for people with diagnosed diabetes.

Those figures describe different things. People with diabetes also need care unrelated to diabetes. The attributable-cost estimate aims to isolate the additional spending caused by the disease, including its complications.

That distinction makes the argument more concrete. The financial burden of diabetes extends well beyond glucose monitors and prescriptions. It includes the consequences of kidney damage, cardiovascular complications, and other problems that can develop over years.

Metabolic illness also extends beyond diagnosed diabetes, although its overlapping conditions make the costs difficult to add together cleanly.

For a health system, these conditions create recurring expenses. For a patient, they can mean decades of medication, appointments, limitations, and uncertainty. The spending figures capture only part of that burden.

Why GDP calls this growth

On a company income statement, an expense reduces profit. In GDP, healthcare spending is output. Every dialysis session, emergency room visit, and insulin prescription is counted as production and adds to the size of the economy. A country that gets sicker and spends more managing that sickness posts a larger GDP. A country that prevents a case of type 2 diabetes removes decades of spending from the same number and, on paper, shrinks slightly.

GDP was designed to measure transactions, so it has no way to tell the difference between buying health and buying the management of disease. The climb toward 20.6% gets reported as a story about prices and policy, but it is better read as a running measure of how much chronic illness the country is paying to manage. That money also has an opportunity cost. Employer premiums come out of what could have been wages, and federal health spending competes with everything else the government funds.

When better health costs more upfront

Modern obesity treatments illustrate why the relationship between health and spending is complicated.

CMS identifies strong use of diabetes and obesity drugs as a contributor to prescription spending growth. Their costs enter the accounts immediately. Potential savings from avoided complications emerge over time and may benefit a different insurer or public program from the one that paid for treatment.

Those savings do not necessarily cover the drug bill. In a 2024 analysis of expanded Medicare coverage for obesity medications, the Congressional Budget Office estimated that treatment costs would exceed the savings from improved health over the following decade.

A treatment can still be worth paying for. We routinely spend money to relieve suffering and extend life without expecting a financial return. The question is how much health an additional dollar buys. That requires looking beyond whether spending went up or down.

Why GDP calls this growth

Medical care is a service the economy produces. The work of doctors, nurses, laboratories, and hospitals contributes to GDP, including when that work treats an illness we would rather have prevented. GDP measures production, and it is not a complete measure of human well-being.

There is an important accounting distinction here. Higher prices can increase healthcare spending in dollars without increasing real, inflation-adjusted output. A bigger bill does not automatically represent more care.

Preventing disease also does not necessarily shrink the economy. Money no longer needed for treatment can be spent elsewhere. Healthier people may work more, care for family members, or pursue things illness would have made impossible.

The limitation is that GDP does not directly record the value of avoiding the illness itself. A hospital visit generates measurable economic activity. The relief of never needing that visit has no equivalent line in the accounts.

Why you should care

You help finance the healthcare system even in years when you barely use it. Its costs reach you through premiums, taxes, and the compensation budgets of employers. Its performance matters when you or someone you love needs care.

That gives you a stake in both the price of treatment and the amount of avoidable illness that requires it. Price reform, simpler administration, effective treatment, and prevention all deserve attention. Lower spending achieved by leaving people untreated would be a poor outcome. Higher spending that delivers substantial improvements in health can be worth it.

As healthcare approaches a fifth of the economy, the spending milestone alone tells us too little. We should also ask whether people are living longer in good health, whether care is becoming more affordable, and whether fewer families are dealing with preventable complications.

The national accounts can tell us how much healthcare we bought. We still have to ask how much healthier it made us.
