Your share, in context
National debt calculator
See the confirmed U.S. national debt at personal scale: per resident, per taxpayer or for your household, your share of a year’s interest, and how much the debt has grown since the year you choose — your birth year, for example.
How each number is calculated
- Your share of the debt
- Confirmed total public debt ($40.6 trillion, 9 November 2026) ÷ the denominator you choose. Household = per-resident share × household size.
- Share of a year’s interest
- Gross interest expense for FY2026 ($1.36 trillion) ÷ the same denominator.
- Debt in the year you pick
- Gross debt on the last day of that fiscal year ÷ that year’s mid-year resident population.
- Debt added since
- Today’s confirmed debt minus the fiscal-year-end debt of the year you pick.

Why the taxpayer figure is higher: we divide by returns that actually owed income tax — about 104 million — not every return filed or every adult. A smaller, honest denominator gives a larger share; we state it rather than pick whichever count makes the headline biggest. More on the debt per person page.
Calculator questions
Is my share of the national debt a bill I have to pay?
No. Dividing the debt by a population or taxpayer count is a way to understand scale. Nobody is sent an individual share; federal debt is repaid or refinanced from federal revenue and new borrowing.
Which denominator should I use?
Per resident divides by all 341,784,857 U.S. residents, including children. Per taxable return divides by the roughly 104 million individual returns that owed income tax. Per household multiplies the per-resident figure by the number of people you enter.
Are the historical figures adjusted for inflation?
No. Every amount is in nominal dollars as recorded at the time, the way the Treasury publishes the debt. Inflation explains part, but not most, of the growth since earlier decades.
Why is the interest figure so large?
It is gross interest on all Treasury debt in FY2026 ($1.36 trillion), including interest credited to federal trust funds. Net interest, the budget measure, is smaller; the interest-on-the-debt page explains the difference.
