What is an NPS calculator?

An NPS (National Pension Scheme) calculator projects your retirement corpus from regular contributions, then shows how it splits between a tax-free lumpsum withdrawal and the portion that must be used to purchase an annuity, per NPS withdrawal rules (minimum 40% annuitization).

What does "corpus" mean?

Corpus just means the total pot of money you’ve built up — your contributions plus all the growth on them. It’s a term used often in Indian retirement planning, but it simply means "your savings" at that point in time.

How much monthly pension will I actually get?

This calculator shows how your corpus splits between the lumpsum you can withdraw and the amount that must go toward buying an annuity — it does not show the resulting monthly pension amount, because that depends on the specific annuity plan and insurer you choose at retirement, which varies and isn’t something a generic calculator can know in advance. Once you know your annuity corpus from this calculator, check current annuity rates from NPS-empanelled insurers (available on the NPS Trust website) to estimate the monthly pension it would buy.
