Enter your salary and state. We'll show you the real dollar breakdown — federal and state — so you can see exactly what your paycheck is funding.
Estimates based on 2024 federal tax brackets (single filer, no deductions) and published state budget allocations. For illustrative purposes — not tax advice.
Most Americans have no idea how the government spends their money. They know they pay taxes — but the gap between "I paid $18,000 in federal income tax" and "here's what that funded" is invisible. This tool makes it visible, in real dollar amounts based on your actual salary.
The short version: the federal government spent $6.75 trillion in FY2024. The largest categories are Social Security (21.2%), interest on the national debt (14%), Medicare (12.7%), and defense (13%). Education — the category most people assume is a priority — receives just 2.8% of total federal outlays. Less than the interest payments on borrowed money.
The US uses a progressive marginal tax system — meaning different portions of your income are taxed at different rates. You don't pay 22% on your entire salary just because you're in the 22% bracket. You pay 10% on the first $11,600, 12% on the next chunk, and 22% only on the income above $47,150 (2024 rates for single filers).
This tool estimates your federal income tax using 2024 IRS brackets without applying the standard deduction. In practice, the standard deduction ($14,600 for single filers in 2024) would reduce your taxable income — meaning your actual tax bill is likely lower than what this tool shows. We show the gross-income calculation to keep the math simple and the comparison clean.
10% on income up to $11,600 · 12% on $11,601–$47,150 · 22% on $47,151–$100,525 · 24% on $100,526–$191,950 · 32% on $191,951–$243,725 · 35% on $243,726–$609,350 · 37% on income above $609,350.
The single largest category. Over 70 million Americans receive Social Security benefits — retirees, people with disabilities, and survivors of deceased workers. Social Security is largely pay-as-you-go: the taxes you pay this year fund checks that go out this year. There is no vault of money sitting in reserve with your name on it.
In 2024, interest payments on the national debt exceeded the entire defense budget for the first time in modern history. This money goes to the holders of US Treasury bonds — domestic investors, foreign governments (led by Japan and China), and the Federal Reserve. It buys no services, builds no infrastructure, and helps no citizen. It is the compounding cost of decades of deficit spending.
Medicare covers 65 million Americans over age 65 and certain disabled individuals. It's divided into four parts: hospital care (Part A), doctor visits (Part B), prescription drugs (Part D), and private Medicare Advantage plans (Part C). Administrative overhead is approximately 2% — significantly lower than private health insurance.
Defense is the largest discretionary line item — meaning Congress sets its level annually. About 28% goes to military personnel and pay, 33% to operations and maintenance, and roughly 19% to weapons procurement. The Pentagon employs 1.3 million active-duty service members and 800,000 civilians.
Medicaid covers 90 million people — more than Medicare — primarily children, pregnant women, nursing home residents, and low-income adults. The federal government shares costs with states, typically covering 50–77% depending on each state's per-capita income. This bucket also includes ACA marketplace subsidies and the Children's Health Insurance Program (CHIP).
The federal government funds a smaller share of education than most people assume. Most K-12 funding comes from state and local property taxes, not Washington. Federal education dollars go primarily to Pell Grants and student loans, Title I grants for high-poverty schools, special education support under IDEA, and Head Start early childhood programs.
State income tax regimes vary dramatically. Nine states — Texas, Florida, Nevada, Washington, Wyoming, South Dakota, Alaska, Tennessee, and New Hampshire — collect no state income tax on wages. The remaining 41 states use either flat or progressive rates. California's top marginal rate of 13.3% is the highest in the country. Pennsylvania's flat 3.07% rate applies equally to a $30,000 earner and a $3 million earner — critics call it regressive.
State budget priorities also differ significantly. California is constitutionally required (under Prop 98) to direct a minimum share to K-12 education. Illinois allocates a meaningful portion to pension debt service — the state has the worst-funded pension system in the country. New York spends more on Medicaid than Texas and California combined.
