# Understanding Economic Growth Rate: Definition, Formula, and Key Examples

## What Is an Economic Growth Rate?

An economic growth rate is the percentage change in the value of all of the goods and services produced in a nation during a specific period of time, as compared to an earlier period. The economic growth rate is used to measure the comparative health of an economy over time. The numbers are usually compiled and reported quarterly and annually.  

### Key Takeaways

*   Economic growth rate is a critical measure of an economy's health, representing the percentage change in the value of all goods and services produced over time. This measure can indicate whether an economy is expanding or contracting.  
    
*   Gross Domestic Product (GDP) is the most commonly used indicator for measuring economic growth, while Gross National Product (GNP) and Net Domestic Product (NDP) can also be used to provide different perspectives on growth.  
    
*   Factors contributing to economic growth include investment in physical and human capital, technological advancements, a skilled labor force, and effective economic policies that encourage stability and productivity.  
    
*   External factors such as global economic conditions and geopolitical events can significantly influence a country's growth rate, either bolstering or hindering economic progress.
*   High economic growth should be managed sustainably to avoid potential downsides like environmental degradation and income inequality, ensuring that growth benefits are equitably distributed.  
    

## Exploring Economic Growth Rates: Significance and Implications

An economic growth rate is a measure of how well an economy is performing in terms of its overall size and productivity over a specific period, often a year or a quarter. It indicates the percentage change in the total economic output of a country during that time frame. This measurement reflects the economy's ability to [produce goods](https://www.investopedia.com/terms/c/consumer-goods.asp) and services, create jobs, and generate income for its citizens.

A positive economic growth rate signifies that the economy has expanded during the measured period. This often means the country had increased economic activity and output. This growth often leads to higher [employment rates](https://www.investopedia.com/terms/f/fullemployment.asp), improved living standards, and greater opportunities for businesses and individuals. Conversely, a negative economic growth rate suggests economic contraction which can lead to job losses, reduced income, and overall economic hardship.

Economic growth is vital for countries to improve citizens' well-being and to invest in education, healthcare, and infrastructure. It is also closely monitored by policymakers, businesses, and investors to make informed decisions.

## Methods to Measure Economic Growth: GDP, GNP, and NDP Explained

There's three popular ways of measure economic growth. First, [gross domestic product (GDP)](https://www.investopedia.com/terms/g/gdp.asp) is the most common and widely used measure of economic growth. It represents the total value of all goods and services produced within a country's borders over a specific period, typically a year or a quarter.

Second, [gross national product (GNP)](https://www.investopedia.com/terms/g/gnp.asp) measures the total economic output produced by a country's residents, both within the country and abroad. It includes income earned by a country's citizens and businesses from foreign investments and activities. GNP provides a broader perspective on an economy's performance, taking into account its international interactions.

Last, net domestic product (NDP) adjusts GDP for depreciation, reflecting the wear and tear on a country's capital assets. For example, consider how a country's infrastructure or major machinery wear down over time. This adjustment provides a more accurate picture of sustainable economic growth because it accounts for the need to replace or repair these assets.

It's also worth pointing out that the measurements above can also be adjusted for inflation. Real economic measurements are exclusive of inflated prices over time, while nominal terms are based on current, inflated prices.

## How to Calculate Economic Growth Rates: A Guide to Using GDP

This formula shows how an economic growth rate is calculated. Note that for this example, we'll look at GDP though the formula can be used for other types of measurements mentioned above.

$\begin{aligned} &\text{Economic Growth} = \frac { \text{GDP}_2 - \text{GDP}_1 }{ \text{GDP}_1 } \\ &\textbf{where:} \\ &\text{GDP} = \text{Gross domestic product of nation} \\ \end{aligned}$

In the formula above, the numerator calculated the difference in GDP between two periods. Most often, this will be the changed in GDP in a given month, quarter, or year. Then, this difference is divided by the newest GDP calculation. Note that it is entirely possible to calculate negative economic growth. This will occur should a nation's GDP decreases from one period to the next.

## Key Drivers of Economic Growth: Investment, Technology, and More

Many factors influence a nation's economic growth. Below are some key ones, although this is not an exhaustive list.

### Investment

Investment is a cornerstone of economic growth. It includes both physical capital investment such as machinery, factories, and infrastructure and [human capital investment](https://www.investopedia.com/terms/h/humancapital.asp) through education and training. Physical capital investment enhances productivity, while human capital investment equips the workforce with skills

Economies with more investment usually grow faster due to increased capacity and efficiency from expanded activities and improved citizen knowledge.

### Technology

[Technological advances](https://www.investopedia.com/countries-investing-the-most-in-ai-11752340) drive economic growth by improving production, creating new products and services, and boosting productivity. Innovations like the internet, automation, and breakthroughs in healthcare have all had profound impacts on economic growth by enhancing efficiency and creating new industries and job opportunities.

### Labor Force

As touched on under 'Investment', a skilled and growing labor force is essential for economic growth. A larger workforce boosts production, while a skilled workforce enhances productivity and innovation. Education and training investments are crucial for developing a labor force that adapts to changing industries and technologies.

### Economic Policy

Effective policies, like sound [fiscal](https://www.investopedia.com/terms/f/fiscalpolicy.asp) and [monetary strategies](https://www.investopedia.com/terms/m/monetarypolicy.asp), ensure economic stability and growth by managing finances, controlling inflation, and reducing business barriers. Stable and predictable policy environments instill confidence in investors and businesses, encouraging long-term investments and economic expansion.

## Real-World Examples of Economic Growth Rates: U.S. and Beyond

In July 2019, the U.S. marked an economic milestone. Its economy had been experiencing growth continuously since June 2009, making it the longest economic expansion in the nation's history. The U.S. GDP continued to grow until Q4 2019.

Then, as a result of the COVID-19 pandemic, the U.S. GDP dropped. The U.S. experienced a negative growth rate of -0.7% in Q1 2020 and -8.8% in Q2 2020. Between then and Q2 2023, the U.S. once again experienced positive economic growth rate.

Growth rates are relative in statistics and may not always tell the full story. In 2018, the U.S. economy grew by 2.9%. Some economists believe that this number represented a high point for some time to come. They were forecasting an expansion of 2.2% in 2019 and a further slowing in 2020. In this context, not only did the economic growth rate signal actual growth, it indicates the extent in which it grew compared to analyst expectation.

By contrast, the economic growth rate of India fell to 5.8% In the first quarter of 2019, the lowest growth rate in five years. Given the nation's rapid growth in recent years, there was much hand-wringing over a severe slump in industrial output and a fall-off in car sales, both factors in the lower rate.

## What Is the Difference Between Real and Nominal Economic Growth?

Real economic growth adjusts GDP for inflation, providing a more accurate picture of an economy's actual expansion or contraction. Nominal growth does not consider inflation, making it less precise.

## How Do External Factors Impact Economic Growth?

External factors like global economic conditions, international trade, and geopolitical events can influence a country's economic growth rates positively or negatively. Exports, for instance, can boost growth, while global recessions can hinder it.

## What Are the Potential Downsides of High Economic Growth?

High economic growth, when not managed sustainably and equitably, can lead to environmental degradation, resource depletion, and social challenges. It may also exacerbate income inequality if not accompanied by inclusive policies.

## What Is the Relationship Between Inflation and Economic Growth?

Moderate inflation can be a sign of a healthy, growing economy. However, high or volatile inflation can erode purchasing power, create uncertainty, and hinder economic growth by reducing consumer and investor confidence.

## The Bottom Line

Economic growth rate measures the percentage change in a country's economy (often in GDP) over a specific period. It indicates whether an economy is expanding or contracting, serving as a critical indicator of its performance. Factors like investment, technological progress, a skilled labor force, entrepreneurship, and sound economic policies influence economic growth rates.
