Where Do Your Tax Dollars Actually Go?
Of every dollar the federal government spends, approximately 21 cents goes to Social Security, 27 cents to Medicare and health, 13 cents to defense, and 13 cents to interest on the national debt — which now exceeds $1,000 per month for every American household.

Most of your federal tax dollars do not go to a vague bucket called “government.” They go to a handful of large commitments: retirement benefits, healthcare, debt interest, defense, and income support. This page shows where the money goes so you can connect your tax bill to actual policy priorities.
That matters because spending choices become household risks. If debt service keeps rising, lawmakers have fewer options elsewhere. If healthcare and retirement programs dominate the budget, changes in benefits, eligibility, or taxes become much more likely to affect your finances directly.

How PRIA Approached This
This calculator was written by Jon Ragsdale and reviewed by David Duley. PRIA treats tools like this as household policy-risk explainers, not generic widgets. We separate current law from proposals when relevant, translate public rules into plain English, and present the output as an educational estimate rather than personalized advice.

Frequently Asked Questions
- Where does most of my federal tax money go?
- The three largest categories of federal spending are Social Security (~21%), Medicare and health programs (~25%), and defense (~13%). Together, these account for nearly 60% of all federal spending.
- How much of my taxes go to Social Security?
- About 21% of the federal budget goes to Social Security. If you earn $75,000, roughly $2,400 of your federal income taxes (plus your separate FICA contributions) support Social Security.
- How much does the U.S. spend on interest on the national debt?
- In FY2025, net interest payments on the national debt are projected to exceed $800 billion, making it one of the fastest-growing budget categories — roughly 13–14% of federal spending.
- What percentage of taxes goes to welfare programs?
- Safety net programs (SNAP, housing assistance, TANF, etc.) account for approximately 8–9% of the federal budget. This is significantly less than most people estimate.
- How much of my taxes fund education?
- Federal education spending (K-12 and higher education combined) makes up about 4% of the federal budget. Most education funding comes from state and local governments.
- Does foreign aid take a big share of my taxes?
- No. Foreign aid accounts for less than 1% of the federal budget, despite surveys showing Americans estimate it at 25%+. On a $75,000 income, about $80 of your taxes go to foreign aid.
- How is this calculator different from the IRS tax receipt?
- The IRS previously provided a "taxpayer receipt" concept. Our calculator goes further by using your actual income, filing status, and effective tax rate to show dollar amounts for each spending category.
- How has federal spending changed over the last decade?
- Interest on debt and healthcare spending have grown fastest. Defense has shrunk as a percentage of the budget, while Social Security has grown due to demographics. Pandemic-era spending spiked in 2020–2021 and has since declined.

Start Free Watch →Where Your Tax Dollars Go: The Short Answer
The federal budget is more concentrated than most people think. Social Security, Medicare, Medicaid, other health spending, defense, and interest on the debt account for the majority of outlays. That means the biggest policy fights are usually about a relatively small number of giant categories, not dozens of equal-sized programs.
The Biggest Slices of the Federal Budget
Social Security alone accounts for 21% of all federal spending — the single largest line item. When combined with Medicare and health programs (27%), mandatory entitlement spending dwarfs all other categories.
Interest on the national debt has surged to 13% of the budget, roughly tied with defense spending. This is one of the fastest-growing categories: it has more than doubled as a share of spending since 2020.
Why This Matters for Household Policy Risk
Budget composition shapes what lawmakers are likely to do next. When interest costs rise, Congress can borrow more, cut spending, raise taxes, or some combination of all three. When large entitlement programs keep growing, future changes often show up as payroll-tax pressure, Medicare premium changes, retirement-age debates, or tighter eligibility rules elsewhere.
In other words, the budget is not just civics trivia. It is a map of which promises the government is financing now and which tradeoffs may land on households later.
What Most People Get Wrong
- Foreign aid is less than 1% of the budget, not the 25%+ most Americans estimate
- Safety net programs (SNAP, housing, TANF) total about 8%, not the majority
- Education is just 2% at the federal level — most education funding is state/local
