Active Choice & Auto Choice. Based on your financial objectives & risk tolerance, you determine how much money is allocated to each NPS asset class in the active choice. With auto choosing, you can choose with greater ease because the allocation is made depending on your age. Your NPS account matures when you turn 60, and you can take out a lump sum payment of 60% of the entire corpus. Depending on the kind of plan selected, the remaining 40% is utilised to buy an annuity, which offers a regular pension.
