Countries use various measures to gauge their wealth. Below we outline the top 10 countries based on disposable income per capita, identifying how much money a person has available to spend on goods and services after paying their taxes.

Money per capita can refer to income per capita, money supply per capita, gross domestic product (GDP) per capita, or even net worth per capita. Income per capita can refer to discretionary income per capita or disposable income per capita, for example.

Key Takeaways

  • Disposable income per capita is one way to measure a country's wealth. This refers to the average person's income available for spending and saving after taxes have been paid.
  • The United States had $53,122 in disposable income per capita in 2018, the largest of any nation.
  • Other countries with high disposable income per capita figures included Luxembourg, Switzerland, Germany and Australia.

Disposable Income Per Capita Defined

Disposable income measures how much income is left over after a person pays income taxes. It is the money available for spending and savings after subtracting taxes from gross income. Think of disposable income as your earnings minus necessary expenses such as your mortgage payment, groceries and health insurance, but less the taxes you paid.

Income minus these expenses and taxes is known as discretionary income, i.e. income that is available for entertainment and other expenses not necessary for survival. Per capita simply means average per person. Thus, disposable income per capita for a country is calculated by adding all the gross income for the country minus taxes and dividing the sum by the country's population.

This differs from purchasing power parity (PPP), which is another measure of a country’s wealth. PPP is used to compare prices for goods across countries, with the Big Mac Index being one of the most famous examples of PPP.

The following disposable income per capita figures for the top 10 countries are from the Organisation for Economic Co-operation and Development (OECD) as of 2018. Disposable income per capita is specifically the household net-adjusted disposable income per capita according to the OECD and all amounts listed are in U.S. dollars.

The United States, with its 326.7 million people, tops the list with a disposable income per capita measure of $53,122.

The small country of Luxembourg, with an estimated population of about 608,000 people in 2018, had $47,138 in disposable income per capita that year, putting it second in the world. The European country nestled between Germany, France and Belgium had $71 billion in GDP. For context, the U.S. dwarfs Luxembourg in GDP at about 300 times its size. Much of Luxembourg’s economic success stems from banking, where the country has grown into a global financial center.

What Drives Higher Average Incomes?

Disposable income, again, is different from discretionary income. Disposable income refers to the money remaining after taxes. Thus, changing spending habits do not impact disposable income. Instead, higher wages or reducing taxes are key to boosting disposable income.

The key aspects of generating a higher disposable income per capita include a few factors. Ways to increase a country's income per capita can include lowering its population while keeping the income the same. However, that may be tough to maintain, or do, as the trend for most countries is a rising population. Government policies are generally an easier way to boost income per capita, as governments can enact various policies. Others may include boosting the hours worked by employees, government investment, and more training or education for workers. 

Hours Worked

An easier way to increase income per capita is to increase the aggregate number of hours worked. That is, more employees going from part-time to full-time means more income per person. This also goes hand-in-hand with lowering unemployment; more employed people will raise the income per capita.

Government Investment

Investing in technology can help make processes more efficient and boost income potential. More specifically, the allocation of resources in a more effective way can boost income per capita. Government spending, such as on infrastructure and defense, will also boost incomes. As mentioned above, government policies, such as tax programs and subsidies can also boost income per capita.

Education

Better, or more educated, workers can boost incomes. Workers able to do more complex tasks boosts overall incomes. These workers can also implement more productive ways of doing tasks, which can reduce needed hours worked or allow employees to work on more complicated tasks for higher pay.
