This piece will examine the 30 most significant economies on the planet in terms of GDP. You can skip ahead to the section under "Countries by GDP
The Gross Domestic Product measures a country's economic output by tallying the value of all its products and services over a given year.


The larger a country's GDP, the more prosperous it's economy. If a country's GDP rises, it may become better able to provide its citizens with amenities that enhance its standard of living.

Two measures of gross domestic product (GDP) are often used: nominal and PPP.

The value of a nation's annual output of final products and services at current prices, unadjusted for inflation, is known as its nominal gross domestic product (GDP).

When computing GDP and PPP, the disparity in the cost of living across nations is considered.

Products and services often cost less in many developing market nations than in the United States. Therefore, the value of products and services generated in these nations is under-represented in their nominal GDP. GDP PPP adjusts for inflation to more precisely reflect the buying power of GDP. GDP and PPP are more complicated to compute since modifications might be ambiguous and subjective.

Neither metric is inherently superior to the other; instead, they complement one another.

According to many experts, PPP is the only measure of a country's living level since it more accurately represents the buying power of its citizens.

When it comes to actual cash inflows, however, nominal GDP far outstrips GDP and PPP in terms of usefulness.

Many of the World's top economies are nations with either enormous populations and resources, like India and China, or high levels of development, like Japan. Exceptions aside, developing countries often have a smaller gap between their nominal and PPP GDPs than developed economies.

As a result of the recovery from the epidemic, several countries' economies increased in 2022. However, many economists fear 2019 will bring a downturn in economic activity due to the Federal Reserve's seven rate hikes this year.

The stock market returns of nations that are more politically stable, technologically sophisticated, and economically growing than their peers tend to be more significant. Example: the U.S. stock maU.S.et has returned little more than 10% yearly over the previous 40 years, although the U.S. economU.S.has been at the forefront of technological innovation since the early 1980s.

List of the World's 30 Largest Economies Based on Their GDP

The World Bank's projections for nominal GDP growth between 2020 and 2021 served as the basis for our ranking of the 30 nations with the largest economies.

1. United States

2021 GDP: $23 trillion

With a projected $23 trillion in GDP for 2021, the United States is the world's largest economy. The United States is home to both the financial capital of the world in New York City and the global innovation hub in Silicon Valley. The country also has the best military force, the most widely used reserve currency, and the highest ranked academic institutions in the world.

2. China

2021 GDP: $17.73 trillion

China's nominal GDP will be above $17.73 trillion in 2023, making it the world's second biggest economy. However, China has the largest economy in the world in terms of GDP, PPP, since its consumer prices are lower on average than those in the United States. While China's population is four times that of the United States, its GDP per person is far lower.

3. Japan

2021 GDP: $4.94 trillion

As of 2021, Japan's GDP of $4.94 trillion places it third among the world's economies. This year, inflation has been an issue in many nations, although consumer price increases in Japan have been rather mild. The countrywide core consumer price index in Japan increased 3.6% year over year in October, up from a 3% increase in September. Japan's central bank aims to maintain interest rates low to aid the economy, a decision made possible by recent lower inflation data.

4. Germany

2021 GDP: $4.22 trillion

A $4.22 trillion GDP in 2021 makes Germany Europe's largest economy. Germany's economy has been considered one of the most sophisticated in the world for some time, and the country has one of the highest income per capita among major economies, with $50,801.79 in 2016.

2021 GDP: $3.19 trillion

London, England is one of the world's financial capitals and the European headquarters for several of the world's largest investment banks.

6. India

2021 GDP: $3.17 trillion

In 2021, India's GDP was projected to be $3.17 trillion nominally and $7.33 trillion PPP. In general, the cost of goods and services in India is lower than in industrialized nations because the country is still in its emerging stages. Consequently, the size of the economy cannot be inferred from the GDP that is reported in nominal terms. India has one of the world's fastest-growing major economies, with the forecasted expansion of 7% this year and 7.2% next year.

7. France

2021 GDP: $2.94 trillion

With a GDP of $2.94 trillion, France is Europe's second-largest economy. Since nuclear power provides over 70% of the country's electricity, it has one of the lowest carbon-emitting economies in the world on a per capita basis. France plans to enhance its use of renewable energy by installing more solar and wind power generators in the future.

8. Italy

2021 GDP: $2.1 trillion

With a projected GDP of $2.1 trillion in 2021, Italy is one of Europe's major economies. In 2021, services made up around 65% of Italy's GDP, making them the country's most significant economic contributor.

15. Mexico

2021 GDP: $1.29 trillion

In 2021, Mexico's GDP was estimated at $1.29 trillion nominally and $2.61 trillion PPP. The country's closeness to the United States, its large population, and abundant natural resources bode well for its economic growth.

16. Indonesia

2021 GDP: $1.19 trillion

Indonesia has great potential due to its large population, abundant natural resources, and diverse topography. A nominal GDP of $1.19 trillion and a GDP PPP of $3.57 trillion were recorded for the country in 2021.
