As per the provisional estimates of annual national income released by Central Statistics Office (CSO) on May 31, 2018, the GDP at current market prices for the year 2017-18 is estimated to Rs 167.7 lakh crore. Given the exchange rate of Rs 64.45 per US Dollar for 2017-18, the GDP at current market prices is estimated to be USD 2.6 lakh crore.

As per International Monetary Fund (IMF), India's GDP is expected to increase to USD 4.7 lakh crore by 2023. In case the economy grows at the same implied nominal rate as between 2017 to 2023, up to 2025, it is reasonable to expect the GDP to reach the level of USD 5 lakh crore by 2025.

This was stated by Pon Radhakrishnan, Minister of State for Finance in a Written Reply to a question in Lok Sabha.
