Money per capita can be a vague term referring to income per capita, money supply per capita, GDP per capita or net worth per capita. Moreover, even these terms can be vague and describe different forms of income, money supply or wealth. Income per capita can refer to discretionary income per capita or disposable income per capita, for example. Countries often use these various measures to different degrees in order to explain their wealth. This article focuses on disposable income per capita to identify the countries with the most money per capita.

Disposable Income Per Capita Defined

Disposable income is measured by income left over after accounting only for effective taxes; it is the money left over for spending and savings after subtracting taxes on gross income. You can think of disposable income as the money you take in without taking out your necessary expenses, such as mortgage payments, groceries, and health insurance, but less the taxes paid. Income minus these expenses and taxes lead to discretionary income — that income which is available for entertainment and other expenses not necessary for survival. Per capita simply means per person and is often used in economic circles; thus, disposable income per capita for a country is calculated by adding all the gross income for the country less taxes and dividing the sum by the country's population.

The following disposable income per capita figures for the top five countries are from the Organization for Economic Cooperation and Development (OECD) as of 2016. Disposable income per capita is specifically the household net-adjusted disposable income per capita according to the OECD. The average household net-adjusted disposable income per capita for OECD countries in 2016 is $29,016, which should help you put the following amounts in perspective.
