    Frequently Asked Questions

    Your personal share is calculated by dividing the total U.S. national debt (currently 40.06T) by the U.S. population of 335,000,000, which gives approximately $119,575 per citizen. If you calculate per taxpayer instead (using the ~140M Americans who file income taxes), the share rises to $286,126.

    To pay off the entire 40.06T national debt, every U.S. citizen would need to contribute $119,575, or every household roughly $305,784. In practice, paying it off is complicated by ongoing interest costs — the federal government currently pays about $970,000,000,000 per year in interest alone, and new deficit spending continues to add to the total.

    The U.S. national debt grows by approximately $53,241 every second, or about $4.6 billion per day. This rate is derived from recent Treasury data on daily debt increases and includes both new deficit spending and interest accrual on existing debt.

    With annual interest payments of about $970,000,000,000, the interest cost alone works out to roughly $2,896 per citizen per year, or about $241 per person per month. This interest cost has been rising as both the total debt and average interest rates have increased in recent years.
