Purchasing Power Parity (PPP) is a factor by which the price of a basket of goods and services in a particular country has to be multiplied in order to compare it with the same basket in another country.
Example: Country A has the price of a basket of goods and services at 10 dollars. Country B has the price of the same basket at 5 dollars. The PPP for country B is 2. This means that if you want to compare the GDP of countries A and B, you would have to multiply the country B's GDP by 2.
