What is the NPS Calculator?
NPS helps build a retirement corpus through regular contributions. This calculator estimates corpus, annuity amount and pension from monthly contribution, expected return, investment years, annuity share and annuity rate.
Formula used
Formula: Corpus uses SIP-style future value. Monthly pension estimate = annuity corpus x annuity return / 12.
For NPS estimates, treat return and annuity rate as assumptions, then compare a conservative pension case with your expected case.
Input guide
