GDP Gap Calculator


In the realm of economics, understanding the GDP gap is crucial for policymakers and analysts alike. The GDP gap represents the difference between actual gross domestic product (GDP) and potential GDP, indicating the economy’s underutilization or overutilization of resources. Calculating this disparity helps in assessing the economy’s health and formulating appropriate policy responses.

How to Use

This article presents a straightforward method to calculate the GDP gap using a simple online calculator. By entering the required values, users can quickly determine the GDP gap and gain insights into the economic situation.


The formula to calculate the GDP gap is:

GDP gap=Potential GDP−Actual GDP


  • Potential GDP: The maximum sustainable level of output an economy can produce without causing inflation.
  • Actual GDP: The real GDP currently being produced in the economy.

Example Solve

Let’s consider an example where the potential GDP is $20 trillion and the actual GDP is $18 trillion.

GDP gap=20 trillion−18 trillion=2 trillion

Therefore, the GDP gap in this scenario is $2 trillion.


What is Potential GDP?

Potential GDP represents the highest level of output an economy can sustainably produce without causing inflationary pressures. It serves as a benchmark for assessing economic performance.

Why is Calculating the GDP Gap Important?

Calculating the GDP gap provides insights into the economy’s health, indicating whether it’s operating below or above its potential. This information is crucial for policymakers to implement appropriate fiscal and monetary policies.

How Can the GDP Gap Affect Policy Decisions?

A negative GDP gap suggests an economic downturn with unused resources, prompting policymakers to adopt expansionary measures such as tax cuts or increased government spending. Conversely, a positive GDP gap indicates an overheating economy, necessitating contractionary policies like higher interest rates to curb inflationary pressures.


Understanding the GDP gap is paramount for assessing economic performance and guiding policy decisions. By utilizing the provided calculator and grasping its implications, analysts and policymakers can effectively navigate the complexities of macroeconomic management.
