Debt relative to the economy
U.S. debt-to-GDP ratio
A useful scale comparison only when both the debt definition and GDP period are explicit. Ours uses total public debt outstanding divided by nominal annualized GDP.

Why published ratios disagree
The federal government publishes more than one useful debt measure. Gross debt includes intragovernmental holdings; debt held by the public excludes those holdings. International organizations may use “general government gross debt,” which is constructed for comparisons across countries. Dividing any of those by a different GDP vintage produces a different—but not necessarily incorrect—ratio.
When comparing ratios, check four things: debt definition, observation date, GDP definition, and GDP vintage.
Debt-to-GDP questions
What does debt-to-GDP measure?
It compares a stock of debt on a date with the annualized flow of national economic output. It is a scale indicator, not a household-style debt ratio.
Why do different sites show different debt-to-GDP ratios?
They may use gross debt or debt held by the public, annual or quarterly GDP, different dates, or international definitions. Those inputs must be identified before ratios can be compared.
Does a ratio above 100% mean the country is insolvent?
No. It means the selected debt measure exceeds one year of GDP. Sustainability also depends on interest costs, growth, inflation, maturity structure, revenue and policy.
