Global Economy 2025: The Biggest Economies In The World!
Introduction
In the era of globalisation, the influence of one country over the other is usually determined by the size of its economy. The GDP, or Gross Domestic Product, is the most common measure for this calculation. The power of the largest economies in the world is determined by its influence on trade, geopolitics, negotiations and more. This blog explores the structure, growth trend and other dynamics of the top 10 best economies in the world.
Measuring The Size Of An Economy
A valuation of an economy is the product of multiple factors, such as consumption, businesses, production, and more. Measuring these factors separately may not present an accurate picture for comparison. Therefore, countries have boiled down to one measure - Gross Domestic Product. The GDP ranking of the largest economies in the world plays a crucial role in international trade influence, diplomatic power, financing and more.
Apart from GDP, there are other indicators like Gross National Product (GNP), Human Development Index, Wealth Index and Gross National Income (GNI). However, GDP is the most explanatory and popular measure.
What Is GDP and How Is It Calculated?
The biggest economies in the world are decided by their GDP, which measures the total economic value of goods and services produced in the boundary of a country. It is calculated by different methods as follows:
GDP calculation method | Description |
Expenditure | It calculates spending on the products and services. GDP = C+I+G+X Here, C = consumption by households I = investments G = government expenditure X = net export derived by deducting imports from exports. |
Income | It sums up the income of all the factors of production in an economy. |
Production | It calculates the value generated by different sectors at each production level in the country. |
Expenditure method is the most considered GDP calculation approach throughout the world due to its simplicity.
These GDP values are represented in USD as it is one of the most common currencies for trade. Based on the GDP levels, the largest economies in the world are decided. Usually, this country adds significant value to the overall global economy and influence over major aspects of it.

5. India - USD 4.27 Trillion

6. United Kingdom - USD 3.73 Trillion

The country has been one of the top economies in the world of defence manufacturing and export. It contributes nearly 9.6% to the global defence exports from FY 2020-24. Moreover, sectors like hospitality, finance and dairy agriculture have been some of the key contributors12.
The GDP of France will contribute 16.4% to the European GDP in 2023. Moreover, estimates suggest that the GDP of France will grow at 3.3% CAGR up to 202/9.

9. Canada - USD 2.33 Trillion

10. Brazil - USD 2.31 Trillion
Brazil is a key influence and one of the largest economies in the Latin American region. However, in terms of ranking in the top economies in the world, its place has degraded in recent years due to natural disasters, global pressure and internal political issues.
