Amitabh Kant Defends India’s Revised GDP Methodology Amid Debate
India changed the way it calculates GDP, which measures the size of the economy.
Amitabh Kant said the old and new numbers should not be compared directly.
He compared doing so to comparing apples with oranges.
The two methods use different data and calculations.
This is why some FY26 estimates look very different.
Kant said the revised method shows real growth of about 7.8%.
He stressed that the economy did not suddenly grow by 60%.
He said updating the method helps reflect changes in India’s economy, including digital payments, GST and digitisation.
Amitabh Kant said GDP figures from different statistical series should not be directly compared.
He attributed differences between the 2011-12 and 2022-23 series to changed methodology and data frameworks.
Kant said the revised calculations indicate real growth of approximately 7.8%.
FY26 GDP estimates differ sharply between the old and new methodologies, but he said this does not represent 60% economic growth.
He argued that base-year revisions are needed to reflect changes such as digital payments, GST and wider digitisation.

Interpreting different GDP estimates
Methodology Critics
The differing figures have prompted questions and controversy over whether the reported growth numbers are credible.
Amitabh Kant’s Defense
Kant said the figures should not be directly compared because they were calculated under different series and data frameworks.
Meaning of the FY26 increase
Methodology Critics
A comparison between the old-series estimate of ₹201 lakh crore and the new-series estimate of ₹322 lakh crore can appear to show a dramatic increase.
Amitabh Kant’s Defense
Kant said the difference does not mean the economy grew by 60%; it reflects the revised methodology.
Nominal GDP difference
Methodology Critics
The differing nominal GDP estimates contribute to debate over how the revised figures should be understood.
Amitabh Kant’s Defense
Kant said the gap between ₹357 lakh crore under the old method and ₹345 lakh crore under the new method does not mean the economy contracted in nominal terms.
