What the figures show
History / IMF estimatesTonga: IMF data and estimates put government debt at 26.9% of GDP in 2025. The derived debt amount is US$ 0.186148 billion.
- The debt-to-GDP ratio is 4.8 percentage points below its 2024 level.
- This is below the median of 52.85% of GDP across 192 countries with data for the selected year.
- Over 2015–2025, the debt-to-GDP ratio decreases by 24.2 percentage points.
The median is not weighted by economic size. A change in the debt-to-GDP ratio does not necessarily imply the same change in the debt amount. About the data ↗

The DataMapper API does not provide the actual/estimate cutoff for each country and series. Past years are therefore labelled history/IMF estimates, the current year estimate/projection, and later years projections. Historical values can be revised. There is no simulated real-time debt counter.
