NPS Corpus Growth Formula
Your NPS retirement corpus is calculated by compounding regular contributions using the future value of an annuity-due formula: Corpus = C x [((1 + i)^n - 1) / i] x (1 + i), where C is your monthly (or annual) contribution, i is the periodic rate of return, and n is the total number of contribution periods until your chosen retirement age. Because each contribution compounds for a different length of time, contributing early in your career has a disproportionately large effect on the final corpus.
