GDP can be measured in three ways:. Output : The total value of the goods and services produced by all sectors of the economy - agriculture, manufacturing, energy, construction, the service sector and government. Expenditure: The value of goods and services bought by households and by government, investment in machinery and buildings - this also includes the value of exports, minus imports.
Income : The value of the income generated, mostly in terms of profits and wages. Why is it often changed later? What are its limitations? GDP growth doesn't tell the whole story. Hidden economy: Unpaid work isn't captured in official figures, such as caring for an elderly relative Inequality: GDP growth doesn't tell us how income is split across a population - rising GDP could result from the richest getting richer, rather than everyone becoming better off. Why is the cost of living going up?
Should GDP take more account of environmental damage? Alternative measures have been developed. Related Topics. Published 2 August Published 6 August Another example is when considering how much money governments borrow or lend during a year and how much public debt money the government owes they have built up over time; these are often presented relative to GDP. In , the government deficit when government's expenditure is greater than its income in the EU was 1.
The change of GDP over time is the most important indicator of economic growth. More information on the various uses of national accounts in general and GDP in particular is provided in a separate article. Back to Statistics 4 beginners — Introduction.

Example If an engineering company produces some special machines for its own use, a building company builds new offices for itself, or a business develops software for in-house use, these are included in GDP, even though this production is not actually sold.
Equally, if Josefina builds or makes a major change to her own house by herself that would be counted as part of GDP as would any construction work done by unpaid volunteers. So, what work does GDP not reflect? Does GDP have a family? How can GDP be used as a benchmark? GDP is also a key factor in using the Taylor rule , which is a primary method used by central bankers to evaluate economic health and set the target interest rates in an economy. GDP is the monetary value of all the finished goods and services produced within a country's borders in a specific time period and includes anything produced within its borders by the country's citizens and foreigners.
It is primarily used to assess the health of a country's economy. The GDP of a country is calculated by adding the following figures together: personal consumption; private investment; government spending; and exports minus imports.
The figure is generally expressed as a dollar amount and its growth rate as a percentage change from one period to the next where the time period is typically quarterly or yearly. While quarterly growth rates are a periodic measure of how the economy is faring, annual GDP figures are often considered the benchmark for the overall size of the economy. Nominal GDP takes current market prices into account without factoring in inflation or deflation.
Nominal GDP looks at the natural movement of prices and tracks the gradual increase of an economy's value over time. The GDP for the U. On the contrary, real GDP factors in inflation. Economists generally prefer using real GDP as a way to compare a country's economic growth rate. Real GDP is how economists can tell whether there is any real growth between one year and the next. It is calculated using goods and services prices from a base year, rather than current prices, in order to adjust for price changes.
There are three primary ways of calculating GDP: first, by adding up what everyone earned in a year known as the income approach or by adding up what everyone spent in a year the expenditure method. Logically, both measures should arrive at roughly the same total. The income approach, which is sometimes referred to as GDP I , is calculated by adding up total compensation to employees, gross profits for incorporated and non-incorporated firms, and taxes less any subsidies.
The expenditure method is the more common approach and is calculated by adding private consumption and investment, government spending, and net exports. Finally, GDP can equivalently be measured based on the value of goods or services produced in an economy over the course of the year the production or output approach. Because economic output requires expenditure and is, in turn, consumed, these three methods for computing GDP all arrive at the same value.
In general, the following simplified equation is often employed to calculate a nation's GDP via the expenditure approach:. GDP is an important measurement for economists and investors because it is a representation of economic production and growth.
Both economic production and growth have a large impact on nearly everyone within a given economy. When the economy is healthy, there is usually a lower level of unemployment, and wages tend to increase as businesses hire more labor to meet the growing demand of the economy. Economists look at positive GDP growth between different time periods usually year-to-year to make an assessment of how much an economy is flourishing.

Gross domestic product or GDP is perhaps the most talked about economic concept. How is GDP calculated? The last measure, total spending, is perhaps the most familiar and can be broken down as: Household spending forms the biggest part, accounting for about two thirds of GDP. When GDP goes up, the economy is growing — people are spending more and businesses may be expanding. GDP growth, however, is not the whole story when gauging how well economies are doing.
What are wider measures of well-being?
