Formula & Explanation
The NPS corpus grows using monthly compounding on contributions until retirement age 60:
Corpus = Σ contributions compounded monthly at expected rate
At retirement, by regulation at least 40% of the corpus must be used to purchase an annuity, which pays a monthly pension. The remaining amount can be withdrawn as a lump sum (tax-free up to 60% of the corpus).
