How to Calculate the Growth Rate of Nominal GDP
The growth rate of nominal Gross Domestic Product (GDP) refers to the rate at which a country’s economy expands over time, without adjusting for inflation. Calculating the growth rate of nominal GDP is an essential step in understanding a nation’s economic performance and can be used for decision-making by government agencies, businesses, and individual investors. In this article, we will discuss the steps involved in calculating the growth rate of nominal GDP.
Step 1: Gather the required data
In order to calculate the growth rate of nominal GDP, you will need data on a country’s GDP for consecutive years. This information is usually available from official sources like national statistical offices, central banks, or international organizations such as the World Bank or International Monetary Fund.
Step 2: Understand the formula
The formula used for calculating the growth rate of nominal GDP is as follows:
Nominal GDP Growth Rate (%) = [(Nominal GDP in Current Year – Nominal GDP in Previous Year) / Nominal GDP in Previous Year] x 100
Step 3: Apply the formula
To calculate the growth rate of nominal GDP, insert the nominal GDP values from two consecutive years into the formula:
- Subtract the previous year’s nominal GDP from the current year’s nominal GDP.
- Divide this difference by the previous year’s nominal GDP.
- Multiply this result by 100 to express it as a percentage.
Example:
Assume that we want to calculate the growth rate of nominal GDP for an economy in which:
Nominal GDP in previous year (Year A) = USD 1,200 billion
Nominal GDP in current year (Year B) = USD 1,300 billion
Now, applying our formula:
[(1,300 – 1,200) / 1,200] x 100 = (100 / 1,200) x 100 = 0.0833 x 100 = 8.33%
This means that the growth rate of nominal GDP from Year A to Year B is 8.33%.
Conclusion:
Calculating the growth rate of nominal GDP is a straightforward task that provides valuable insights into a nation’s economic performance. By following the steps outlined above, you can gain an understanding of how quickly an economy is growing in nominal terms and make informed decisions based on this knowledge. However, it is essential to remember that this calculation does not account for inflation, so interpreting the trends in real GDP growth rate might provide a more accurate reflection of economic performance in the context of changing price levels.
