What is NPS?

The National Pension System (NPS) is a government-backed retirement savings scheme that allows individuals to invest regularly during their working years and receive a pension after retirement. The core concepts include compounding, asset allocation, annuity purchase, and long-term wealth creation.

Understanding how contributions grow over time is essential for realistic retirement planning, and that’s exactly where the NPS Calculator plays a critical role.

Formula & Equations Used

Core NPS Calculation Formula
Future Value of Investment (FV)
FV = P × {[(1 + r)ⁿ − 1] / r}
Where:
P = Annual contribution
r = Expected annual rate of return
n = Number of years invested
Pension & Lump Sum Calculation
Lump Sum Withdrawal = 60% of Total Corpus
Annuity Purchase = 40% of Total Corpus
