The purpose of the U.S. debt clock is to provide information to the general public about the financial state of the country. It works by providing real-time and accurate information on a continual basis.
Several organizations make debt clocks available to the public, including usdebtclock.org, nationaldebtclocks.org and brillig.com. While all national debt clocks show a continual running total of the national debt, several break the debt down into a number of metrics, including revenues, spending, budget items and trade financials. For instance, the national debt clock at usdebtclock.org breaks down the national debt into an extensive subset of components, such as debt per citizen, debt per taxpayer, total debt per family and interest on the debt.
