List of countries by GDP (PPP)

This article includes a list of countries by their partial forecasted estimated gross domestic product (PPP). Countries are sorted by GDP PPP partial forecasted estimates from financial and statistical institutions in the limited period Janaury-April 2017, which are calculated at market or government official exchange rates. The GDP dollar (INT$) data given on this page are derived from purchasing power parity (PPP) calculations.

Comparisons using PPP are arguably more useful than nominal when assessing a nation's domestic market because PPP takes into account the relative cost of local goods, services and inflation rates of the country, rather than using international market exchange rates which may distort the real differences in per capita income. It is however limited when measuring financial flows between countries. PPP is often used to gauge global poverty thresholds and is used by the United Nations in constructing the human development index.

The first table includes estimation for the year 2017, for all current 191 International Monetary Fund (IMF) members, as well as Hong Kong and Taiwan (the official list uses "Taiwan, Province of China"). Data are in millions of international dollars and were calculated by the IMF. Figures were published in April 2017. The second table includes data mostly for the year 2015 for 180 of the 193 current United Nations member states, as well as the two Chinese Special Administrative Regions (Hong Kong and Macau). Data are in billions of international dollars and were compiled by the World Bank. The third table is a tabulation of the CIA World Factbook Gross Domestic Product (GDP) (Purchasing Power Parity) data update of 2016. The data for GDP at purchasing power parity have also been rebased using the new International Comparison Program price surveys and extrapolated to 2007.
