Nominal GDP is the measure of a country’s economic output at current market prices and is used to calculate the growth rate of the economy. On the other hand, Real GDP is the measure of a country’s economic output adjusted for inflation and gives a more accurate picture of economic growth.
We’ll take a closer look at the differences between Nominal GDP and Real GDP and why it’s important to consider both when analyzing the economic performance of a country.
Nominal GDP vs. Real GDP
| Nominal GDP | Real GDP |
|---|---|
| Nominal GDP is defined as the total value of all goods and services produced in a year, not adjusted for inflation | Real GDP is defined as the total value of all goods and services produced in a year, adjusted for inflation |
| It is calculated as GDP = P x Q, where P is the current market price of goods and services, and Q is the quantity produced | It is calculated as Real GDP = P x Q, where P is the base year price of goods and services, and Q is the quantity produced |
| It reflects as changes in both the quantity of goods and services produced and the current market prices | It reflects as changes in the quantity of goods and services produced only, with the effect of price changes removed |
| Nominal GDP can be distorted by changes in the general price level, such as inflation or deflation | Real GDP is less likely to be distorted by changes in the general price level, as it adjusts for inflation |
| It can be used for comparing economic performance across countries or time periods, but the comparison may be misleading due to differences in price levels | It provides a more accurate comparison of economic performance across countries or time periods, as it accounts for differences in price levels |
| Nominal GDP may lead policymakers to make inaccurate decisions if it is not adjusted for inflation | Real GDP provides a more reliable basis for making policy decisions, as it reflects changes in the quantity of goods and services produced and avoids the distorting effects of inflation |
| It iis important in showing changes in the size of an economy over time, but real GDP is more significant in measuring the economic growth rate | It is more significant in measuring economic growth rate, as it provides a more accurate picture of changes in the quantity of goods and services produced over time. |
What is nominal GDP?
Nominal GDP (Gross Domestic Product) refers to the total value of all final goods and services produced within a country’s borders during a specific period, usually a year, without adjusting for inflation. It represents the current prices of goods and services produced by an economy, including changes in the quantity of goods and services produced.
Nominal GDP is the measure of economic production that takes into account the current market prices for all goods and services produced in an economy. It is measured as the total value of all goods and services produced within an economy during a specific period of time, usually one year. This measure is not adjusted for inflation, meaning it can be used to compare output across different years but not to measure the true purchasing power of money.
What is real GDP?
Real GDP is a measure of economic performance that adjusts nominal GDP to account for changes in the purchasing power of money over time. This means that it factors in inflation, making it a more accurate indicator of economic growth.
It measures the total value of all goods and services produced by an economy in a given period, after accounting for changes in price level due to inflation or deflation. In other words, it gives an indication of how much output an economy can actually buy with its level of production.
Real GDP measures the total value of goods and services produced at constant base-year prices. This means that the comparison between nominal and real GDP gives a more accurate picture of economic performance since it takes into account fluctuations in price due to inflation or deflation. As such, when considering economic growth, policymakers should focus on real GDP rather than nominal GDP.
Key differences between nominal and real GDP
The main difference between nominal GDP and real GDP is how each measure takes inflation into account. Nominal GDP measures a nation’s economic output without adjusting for changes in the prices of goods and services. Real GDP, on the other hand, measures a nation’s economic output while adjusting for inflation.
Moreover, nominal GDP values all production at current market prices, while real GDP values all production at constant prices. This means that any increase in nominal GDP could be due to rising prices, not necessarily an increase in the production of goods and services. In contrast, real GDP adjusts for inflation and therefore is a better measure of the actual growth of an economy over time.
For example, if a country produced $100 worth of goods and services in a given year, and prices rose by 10 percent the following year, nominal GDP would show a 10 percent increase even though no new goods were actually produced. However, real GDP would show no change since it takes inflation into account.
This difference is important for policy-makers who must make decisions about economic growth. By using real GDP instead of nominal GDP, they can get a more accurate picture of how much the economy has grown and be better informed when making decisions about economic policies.

Nominal GDP vs. real GDP: The importance of adjusting for inflation in measuring economic performance
Nominal GDP measures the total value of all goods and services at their current market prices. The figure is calculated by taking the quantity of each good and service produced and multiplying it by its current market price. This figure does not take into account inflation, which can significantly impact the accuracy of this measure.
Real GDP is different in that it takes into account the effects of inflation. It measures the total value of all goods and services at their base-year market prices. To calculate real GDP, economists adjust the nominal GDP figures by using a specific index to reflect inflation changes over time. This allows them to compare the purchasing power of a currency across different years, as well as to more accurately measure economic growth.
Adjusting for inflation allows policymakers to accurately assess the state of the economy and make informed decisions on fiscal and monetary policies. For instance, if nominal GDP is growing rapidly due to inflation, policymakers may choose to tighten monetary policy to prevent overheating of the economy. In contrast, if real GDP growth is sluggish, policymakers may choose to use fiscal or monetary stimulus to encourage economic growth.
In conclusion, adjusting for inflation is crucial in measuring economic performance, and Real GDP provides a more accurate picture of an economy’s growth over time than Nominal GDP. Understanding the difference between these two measures is important for policymakers, investors, and anyone interested in assessing the health of an economy.
The role of nominal GDP and real GDP in policy-making: Why one measure isn’t enough.
When it comes to policy-making, it is important to have a comprehensive understanding of the state of the economy. One way of doing this is by comparing Nominal GDP and Real GDP. While the two concepts are similar in that they measure a country’s total economic output, there is an important difference between them: Real GDP takes into account the impact of inflation on prices.
Nominal GDP measures the value of goods and services produced in a given period at their current market prices. In other words, it simply reflects the total amount spent on products and services without adjusting for inflation. This means that the increase in nominal GDP from one period to the next may be due to either an increase in the volume of goods and services produced or an increase in their prices—or both.
Real GDP, on the other hand, adjusts for changes in price by taking into account the effect of inflation. It is calculated by multiplying nominal GDP with a price deflator, which is an index that measures changes in price over time. This allows for an accurate comparison of economic output from one period to the next since it eliminates the effect of inflation on prices.
Because of this difference between Nominal GDP and Real GDP, economists often use both measures when formulating policy. For example, if Nominal GDP is rising while Real GDP is stagnant or declining, it may indicate that the increase in economic output is due more to higher prices rather than increased production. In such cases, policymakers can use this information to design policies that can help boost production, such as tax cuts or subsidies.
Similarly, if Real GDP is rising while Nominal GDP is stagnant or declining, it may suggest that prices are not increasing fast enough to support higher levels of economic growth. In such cases, policymakers can use this information to design policies that can help boost prices, such as increasing the money supply or reducing taxes.
So, Nominal GDP and Real GDP serve different purposes when it comes to policy-making. While Nominal GDP offers a broad view of economic activity, Real GDP provides a more accurate picture by adjusting for changes in prices. As such, it is important for policymakers to take both measures into consideration when designing policies that can ensure sustainable economic growth.
