The Government of India replaced the Planning Commission with a new institution named NITI Aayog. NITI Aayog stands for National Institution for Transforming India. The NITI Aayog came into existence on 1 January 2015. Before the establishment of NITI Aayog, the Planning Commission operated for 65 years as it was formed in March 1950 and was replaced on 1 Jan 2015.

In 2014, the Planning Commission was replaced by NITI Aayog, a more robust organisation. It is more like a think-tank that works with stakeholders for developing the country.
The Planning Commission of India was an organization in the Government of India, which formulated India’s 5-Year Plans, among other functions. The Planning Commission was charged with the service of the opportunities to all for employment in the service of the community.
The PC was reporting directly to the PM of India. It was established on 15 March 1950, with PM Jawaharlal Nehru as the chairman. The PC did not derive its creation from either the Constitution or statute but was an arm of the Central/ Union Government.
