In order to gauge the economic performance of a country, economists use several key macroeconomic indicators. One such indicator is the Gross Domestic Product (GDP), which represents the total value of all goods and services produced within a country during a specific period. The growth rate of GDP is an essential measure to identify trends and track economic progress. Calculating nominal GDP growth rate allows you to evaluate the change in monetary value without adjusting for inflation.

In this article, we will guide you step-by-step on how to calculate the nominal GDP growth rate.

Step 1: Understand Nominal GDP

First, it is essential to grasp the concept of nominal GDP. It refers to the total worth of all goods and services produced in a country during a given year at current market prices. In simpler terms, nominal GDP measures a nation’s output based on monetary value without accounting for price changes due to inflation or deflation.

Step 2: Obtain Nominal GDP Values

To calculate nominal GDP growth rate, you need two consecutive years’ nominal GDP values – usually referred to as Year 1 (Y1) and Year 2 (Y2). These figures are typically available through various online sources like World Bank Open Data, IMF databases, or national statistical agencies’ websites.

Step 3: Calculate Nominal GDP Growth Rate

Once you have gathered the required data, use the following formula to compute the nominal GDP growth rate:

Nominal GDP Growth Rate = ((Y2 – Y1) / Y1) * 100

In this equation, subtract Year 1’s nominal GDP (Y1) from Year 2’s nominal GDP (Y2). Divide the result by Year 1’s nominal GDP (Y1), and finally, multiply by 100 to express the value as a percentage.

Let’s illustrate this with an example:

Suppose that Country A has a nominal GDP of $1,000 billion in Year 1 and $1,100 billion in Year 2.

Nominal GDP Growth Rate = ((1100 – 1000) / 1000) * 100

= (100 / 1000) * 100

= 10%

In this example, Country A’s nominal GDP growth rate is 10% from Year 1 to Year 2.

Understanding the significance of the Nominal GDP Growth Rate

A positive nominal GDP growth rate signifies economic expansion, showcasing an increase in overall production and consumption. Conversely, a negative growth rate indicates an economic contraction. However, one must remember that nominal GDP growth rates do not account for inflation or deflation. Hence, comparing or analyzing nominal growth rates across periods with varying inflation rates might be misleading.

For more accurate comparisons and analysis of real economic progress, economists often use real GDP growth rate – which adjusts GDP figures for inflation. Nonetheless, calculating and understanding the nominal GDP growth rate is still an essential skill that allows you to track a country’s economic activities and performance over time.
