Debt-to-GDP Ratio
The debt-to-GDP ratio compares a defined government-debt stock with annual nominal economic output to provide a scale indicator for public-finance analysis.
National and public-sector debt measures, debt-to-GDP ratios, per-capita comparisons, refinancing, and fiscal-burden analysis.
Public Debt Ratios and Burden explains how outstanding government obligations are defined, scaled, and compared. Start with National Debt for central-government debt, including U.S. gross federal debt and debt held by the public. Use Public Sector Debt when the reporting perimeter extends beyond the national government.
Ratios and per-capita measures help scale a debt stock, but they do not replace analysis of revenue capacity, interest cost, maturity, currency, assets, contingent obligations, and market access.
| Guide | Use it for |
|---|---|
| National Debt | Central-government debt, U.S. gross federal debt, debt held by the public, intragovernmental holdings, and debt-limit distinctions. |
| Public Sector Debt | A wider institutional perimeter that may include public corporations, with gross, net, consolidated, debt-service, and refinancing distinctions. |
| Debt-to-GDP Ratio | Scaling a consistently defined debt stock by annual nominal output and decomposing changes through fiscal flows, growth, interest, and other adjustments. |
| Per-Capita Debt | Scaling gross, net, direct, or overlapping debt by the corresponding population after defining the numerator. |

The debt-to-GDP ratio compares a defined government-debt stock with annual nominal economic output to provide a scale indicator for public-finance analysis.
National debt is the outstanding debt of a national government, measured under a defined institutional boundary and accounting framework.
Per-capita debt divides a defined government-debt measure by the corresponding population to compare debt scale across places or periods.
Public sector debt is the outstanding debt of general-government units and public corporations within a stated statistical boundary.
