Formula & Mathematical Explanation

\displaystyle A = P \times \left[ \frac{(1 + i)^n - 1}{i} \right] \times (1 + i)

NPS contributions accumulate monthly like a SIP. Upon reaching age 60, a minimum of 40% of the accumulated corpus (A) must be reinvested in an annuity to generate a monthly pension, and the remaining can be withdrawn as a lump sum.
