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
