India’s GDP figures in the last few months have raised a lot of debate in the Indian economy, and of course, the difference between 7.8% and 2.6%. They may seem very different and are far from being two different official GDP growth rates. Real GDP and nominal GDP are very different from the new GDP series, and the other 2.6% calculation is important for the debate.
According to the latest official estimates, India’s real GDP, or GDP at constant prices, was estimated in the first quarter of FY2026-27 at ₹81.36 lakh crore as compared to ₹75.46 lakh crore in the corresponding quarter of FY2025-26. This translates to a real GDP growth rate of 7.8%, so the official figures suggest that the Indian economy grew significantly in the April-June quarter as a function of price changes.
The same data shows that nominal GDP, or GDP at current prices, was ₹88.27 lakh crore in Q1 FY2026-27, compared to ₹80.00 lakh crore in Q1 of the previous financial year. That is 10.3% nominal GDP growth. The difference between 7.8% real growth and 10.3% nominal growth is mainly due to the effect of prices and inflation on the value of economic output.
What actually is real GDP? Real GDP measures the growth in the real volume of goods and services produced by an economy without adjusting for changes in the price of goods and services. If more goods and services are produced, real GDP increases, and this is why real GDP growth is one of the most widely used indicators for economic activity growth.
Nominal GDP works differently. It measures economic output at current prices; that is, changes in production and changes in prices are reflected in the number. So, nominal GDP growth is generally higher than real GDP growth when prices rise. In India's latest Q1 figures, the 10.3% nominal growth rate is therefore not directly comparable with the 7.8% real growth rate because they measure economic growth using different price treatments.
The 2.6% figure is where the current controversy becomes more complicated. It is not the official real GDP growth rate for Q1 FY2026-27. Rather, it is based on an alternative calculation to the previous one, based on a comparison of India's earlier GDP figures and updated estimates. Some think that applying the previous statistical model results in a much lower nominal growth rate, and Reuters estimates this to be around 2.6%.
Part of the reason for disagreement stems from India’s new GDP series. In February 2026, the Ministry of Statistics and Programme Implementation (MoSPI) released a new national accounts series with 2022-23 as the base year and not 2011-12 as the previous base year. The move was made to capture structural changes in the economy, take into account new data sources and to develop better estimation methods.
This change matters because GDP is not simply a number taken from the beginning and divided by two numbers. National accounts contain enormous quantities of data from all over the world, price indices, sector-specific estimates, production information, and methodological assumptions. Therefore, directly mixing figures from the old and new GDP series can give misleading results.
MoSPI has defended the new estimates, saying that national accounts are subject to revisions as better and more complete information becomes available. The ministry has also said that the updated series incorporates improved price indices and that the 2022-23 base year remains unchanged within the new framework.
The 7.8% figure itself is a strong start to FY2026-27. The growth rate was higher than the Reserve Bank of India’s forecast of 7% and market expectations of 7.1%. Investment, manufacturing and services were some of the key contributors.
But GDP growth should not be interpreted as meaning that every individual or every sector of the economy is growing at 7.8%. GDP is an aggregate measure. It doesn’t tell us how income is distributed, whether employment opportunities are improving equally across sectors, or whether households are experiencing the same degree of economic improvement.
But the debate continues to show why the economic statistics should be closely examined. The 7.8% is the official real GDP growth rate under the new 2022-23 base-year series, and 10.3% is the nominal GDP growth rate. The 2.6% figure is a different calculation and not the official GDP growth rate of India.
In simple terms, the easiest way to understand the numbers is this: 7.8% tells us how much India's real economic output grew according to the latest official methodology; 10.3% tells us how much the economy's value at current prices increased; and 2.6% relates to a disputed alternative calculation using a different statistical comparison.
For readers of India's economic performance, the most important point is to avoid comparing these percentages as though they measure the same thing. The choice of GDP series, base year, prices and methodology can significantly influence the resulting calculations.
The latest GDP data in India therefore paint a picture of strong economic growth, and the controversy around the 2.6% figure shows the need to know how data are generated. As economists study the new series and more data are released, the debate will continue. In the meantime, the official story is clear: India had 7.8% real GDP growth in Q1 FY2026-27.
