Debt Explained



Over 90% of our data is directly obtained from official government agencies and central banks. When this has not been possible we have used data from the CIA, The World Bank or Eurostat. This raw data is then processed through our algorithms which use, amongst other variables, the average 10 year interest rate paid on the debt to accurately calculate the current debt amount at the time you are viewing the debt clock. We believe our calculations are correct working from the data that we have collected.

Debt Definition

This is the gross government debt, this means the amount of money (the repayment value) owed by government today calculated according to the SDDS 2014 and The Maastricht Treaty guidelines. In keeping with the aforementioned guidelines we do not subtract from the debt any financial assets the government may own. Please also note the debt figures do not take into account any government future payments e.g. pensions payable next year. Or business and private borrowing e.g. you buying a car with a loan, buying a house with a mortgage or a business buying a machine with a bank loan.

Exchange Rates

We update our exchange rates hourly using data from the European Central Bank.


You may use our published figures as long as you credit, and send us an email to notify us of your use.
