The SUPRAVAT.IN NPS Calculator helps you estimate your National Pension System retirement corpus, total contributions, investment growth and projected monthly pension. Enter your current age, retirement age, monthly contribution, expected return and annuity assumptions, and it instantly shows the projected corpus and pension — all formatted in Indian ₹. It works as an NPS corpus calculator, an NPS maturity calculator and an NPS pension calculator in one place.
What is NPS?
NPS, or the National Pension System, is a voluntary, long-term retirement savings scheme regulated by the Pension Fund Regulatory and Development Authority (PFRDA) in India. Subscribers contribute regularly during their working years to build a retirement corpus, which is then used at exit to purchase an annuity and, where applicable, withdraw a portion as a lump sum. NPS investments are market-linked, so returns are not guaranteed.
What is the National Pension System?
The National Pension System is designed to help individuals accumulate savings for retirement over a long horizon. Contributions are invested across asset classes according to the subscriber's chosen allocation and pension fund manager. Because the money stays invested for many years, compounding plays an important role in growing the corpus. This NPS calculator India tool models that compounding using a transparent monthly projection so you can see how your contributions could grow.
How an NPS calculator works
An NPS retirement calculator takes your inputs — current age, exit age, current corpus, monthly contribution, annual contribution increase, expected return, annuity rate and annuity allocation — and projects the corpus month by month until your exit age. Each month it applies the assumed monthly return to the existing balance and then adds your contribution. Once a year it steps up the contribution by the annual increase you entered. At exit it splits the corpus into a lump sum and an annuity amount based on your assumed allocation, then estimates the monthly pension from the annuity amount and annuity rate.
How monthly contributions grow over time
Because returns are applied every month, each contribution starts earning returns from the month after it is added. The longer your contribution period, the more time the early contributions have to compound. This is why starting early has a large effect on the projected corpus even when the monthly contribution is modest.
How expected return affects projected corpus
The assumed annual return is one of the most sensitive inputs in an NPS corpus calculator. A higher assumed return grows the corpus faster, but because NPS returns are market-linked, a higher assumption also means more uncertainty. This NPS calculator defaults to 10% as a planning assumption, but the field is fully editable. Trying a range of return assumptions helps you see how sensitive the projection is to this input.
How annual contribution increases affect the projection
The Annual Contribution Increase field lets your monthly contribution step up once every year by the percentage you enter. Even a small annual increase can meaningfully raise the projected corpus because the higher contributions also compound for many years. Entering 0% keeps the monthly contribution flat for the whole period, which is useful as a baseline scenario.
What is NPS corpus?
The NPS corpus is the accumulated value of your NPS account — your contributions plus the investment returns earned over time. This NPS maturity calculator estimates that corpus using your inputs and the stated monthly-compounding convention. The actual corpus depends on market performance, your contribution pattern and the rules applicable to your account.
What is an annuity?
An annuity is a regular pension payout purchased from an annuity service provider using a portion of your corpus at exit. The annuity rate is the percentage of the annuity amount paid out each year. This NPS pension calculator uses an Assumed Annuity Rate (default 6%) only to estimate the projected monthly pension from the amount you allocate to annuity. Actual annuity rates and payouts depend on the annuity provider, the product chosen and prevailing conditions at exit.
Difference between estimated corpus and estimated pension
The estimated corpus is the total accumulated balance at exit. The estimated pension is the regular monthly income generated from the portion of that corpus allocated to annuity. They are different things: the corpus is a lump balance, while the pension is an income stream derived from part of that balance using an assumed annuity rate. A larger corpus generally supports a larger pension, but the pension also depends on the annuity allocation and annuity rate you assume.
Why actual NPS returns can differ from calculator projections
Actual NPS returns are market-linked and vary over time, annuity rates depend on the annuity provider and prevailing conditions at exit, and NPS exit and withdrawal conditions depend on the applicable PFRDA rules, subscriber category, corpus and exit circumstances — all of which may change. This calculator provides an estimated projection based on the inputs and assumptions shown on the page; it is not a guarantee of future corpus or pension. Always verify current NPS rules with PFRDA or an authorised source before making financial decisions.
Important: This NPS calculator does not provide personalised investment advice and does not calculate tax savings. Tax benefits under NPS depend on the applicable tax regime and section limits, which may change. The annuity allocation used here is a user-defined modelling assumption for the calculator, not a statement of the current NPS withdrawal rule or a promise of eligibility or payout.
