It includes both internal debt (owed to residents) and external debt (owed to foreign lenders). The burden and management of national debt play a critical role in a country’s fiscal policy and economic health.

Mathematical Models
Debt-to-GDP Ratio
The debt-to-GDP ratio is a key metric used to assess a country’s debt relative to its economic output.
$$ \text{Debt-to-GDP Ratio} = \frac{\text{National Debt}}{\text{Gross Domestic Product (GDP)}} \times 100 $$
Example Calculation
- National Debt: $20 trillion
- GDP: $15 trillion
- Debt-to-GDP Ratio: \( \frac{20}{15} \times 100 = 133.33% \)
