Explanation:

Atal Pension Yojana (APY)
The Atal Pension Yojana (APY) was launched to create a universal social security system for all Indians, especially the poor, the under-privileged and the workers in the unorganised sector.

• It is an initiative of the Government to provide financial security and cover future exigencies for the people in the unorganized sector.
• It is administered by the Pension Fund Regulatory and Development Authority (PFRDA) through the National Pension System (NPS).
• This scheme is open to all bank account holders in the age group of 18 to 40 years and the contributions differ, based on the pension amount chosen. 
• Subscribers would receive the guaranteed minimum monthly pension of Rs. 1000 or Rs. 2000 or Rs. 3000 or Rs. 4000 or Rs. 5000 at the age of 60 years, based on the contributions made by the subscriber after joining the scheme.
• The minimum pension would be guaranteed by the Government, i.e., if the accumulated corpus based on contributions earns a lower than estimated return on investment and is inadequate to provide the minimum guaranteed pension, the Central Government would fund such inadequacy.
• Alternatively, if the returns on investment are higher, the subscribers would get enhanced pensionary benefits.
• Subscribers can make contributions to APY on a monthly/ quarterly/half-yearly basis.
