$19.3B

The federal government spent $7.0 trillion in FY2025 — that's $19.3 billion per day, $803 million per hour, or $223,000 every single second, around the clock, every day of the year.

99.8%
debt-to-GDP
In FY2025, the federal government ran a $1.79 trillion deficit — spending 34% more than it collected in taxes. That gap was financed by selling Treasury bonds. About 68% is held domestically; the remaining 32% by foreign governments and investors, with Japan and the U.K. as the largest. By end of FY2025, total public debt hit 99.8% of GDP — nearly double the 50-year historical average.

$15,400
per person collected
In FY2025, the federal government collected $5.26 trillion in revenue — about $15,400 per person in the U.S. Individual income taxes made up about half of that total, with payroll taxes accounting for another 37% — meaning roughly 87 cents of every federal dollar collected came directly from workers' paychecks.
These numbers shift every year — driven by legislation, tariffs, demographics, and policy decisions.
Frequently asked questions
This tool estimates three federal taxes: federal income tax (based on 2025 marginal brackets and the standard deduction), Social Security payroll tax (6.2% up to $176,100), and Medicare payroll tax (1.45% on all income, plus an additional 0.9% over $200,000 for most filers). It does not include state taxes, local taxes, self-employment tax, the Alternative Minimum Tax (AMT), or any tax credits.
Your actual federal tax liability depends on factors this tool doesn't capture: itemized deductions, tax credits (child tax credit, earned income credit, etc.), investment income, self-employment income, retirement contributions, and more. This tool uses the standard deduction and assumes all income is ordinary wage income. Think of it as a directional estimate, not a tax return.
Your paycheck withholding and any refund reflect how much you paid throughout the year versus what you actually owed. This tool estimates what you owe — not what was withheld or refunded. If you received a large refund, you likely had more withheld than required. If you owed money, the reverse. The underlying liability this tool estimates is the same concept; the payment timing differs.
Payroll taxes (Social Security and Medicare) are separate from federal income tax. They're collected specifically to fund Social Security retirement and disability benefits and Medicare health coverage for people 65 and older. They are not part of the general federal budget — which is why this tool's budget allocation chart only reflects your income tax, not your payroll taxes.
State income tax rates and structures vary enormously — from 0% in states like Texas and Florida to over 13% in California. Building an accurate 50-state calculator would require a separate tool. This tool focuses exclusively on federal taxes, which are the same regardless of where you live.
Yes. In FY2025, the federal government spent approximately $7.1 trillion while collecting roughly $5.3 trillion in revenue — a deficit of about $1.8 trillion, covered by borrowing (issuing Treasury bonds). This is why the budget allocation in this tool reflects spending patterns that exceeded total tax revenue. The national debt represents the accumulation of past deficits.
Not literally. The federal government pools all tax revenue and pays all obligations from a general fund. The allocation percentages reflect how total FY2025 federal spending was distributed across categories — not a designated account with your name on it. Social Security and Medicare payroll taxes are a partial exception: they flow into dedicated trust funds, which is why this tool excludes them from the general allocation.
Tax software knows your full situation: credits, deductions, investment income, filing history, and withholding. This tool uses only your gross income and filing status with the standard deduction. It's designed for quick, directional understanding — not to replace a W-2 or tax return. For anything involving actual filing or financial decisions, use a licensed tax professional or IRS-approved software.
This tool assumes: (1) all income is ordinary wage income, (2) you take the standard deduction rather than itemizing, (3) you have no tax credits, (4) you have no additional income sources like capital gains or self-employment, (5) you are not subject to the Alternative Minimum Tax (AMT). Results reflect 2025 IRS brackets under IRS Revenue Procedure 2024-40 and the One Big Beautiful Bill Act.
At $0 income, there is no federal income tax. However, if you have any earned income, Social Security and Medicare payroll taxes still apply from the first dollar. The standard deduction ($15,750 for single filers in 2025) eliminates income tax for wages below that threshold, but payroll taxes are calculated on gross wages before any deductions.
This calculator uses the following simplifying assumptions. Your actual tax liability may differ significantly based on your full financial picture.
- All income is treated as ordinary wage income.
- The standard deduction is applied — not itemized deductions.
- No tax credits are applied (child tax credit, earned income credit, etc.).
- No capital gains, self-employment income, or rental income.
- Alternative Minimum Tax (AMT) is not calculated.
- No retirement contributions (401k, IRA) are deducted.
- Payroll taxes (Social Security, Medicare) are calculated on gross wages.
- Social Security tax applies up to the 2025 wage base of $176,100.
- Additional Medicare Tax (0.9%) applies above $200,000 for single filers.
- Brackets reflect IRS Rev. Proc. 2024-40 and the One Big Beautiful Bill Act.
