NPS Calculator: what it calculates.
The National Pension System (NPS) is a market-linked retirement scheme regulated by PFRDA. Contributions are invested in equity, corporate bond and government bond funds, and at exit part of the corpus must be used to buy an annuity that pays a monthly pension. This calculator projects the corpus and an illustrative pension.
The NPS calculator compounds your yearly contributions at an assumed return until your exit age, then applies the exit rules used here to split the corpus into a permitted lump sum and an annuity, and converts the annuity part into an illustrative monthly pension.
How the calculation works.
Corpus each year = (previous corpus + 12 × monthly contribution) × (1 + r)
- r is the assumed annual return; contributions are treated as one yearly amount at the start of each year.
- Normal exit (age 60 or above, or 15 years or more) uses a 20% minimum annuity; premature exit uses 80%.
- Small corpora: up to ₹8 lakh at normal exit (₹5 lakh premature) can be taken fully as a lump sum, and between ₹8 lakh and ₹12 lakh at normal exit ₹6 lakh is taken as a lump sum.
- Monthly pension = annuity amount × annuity rate ÷ 12. These are the PFRDA exit rules used here; they change.
Worked example. ₹10,000 a month from age 30 to 60 at an assumed 10% return puts in ₹36 lakh and grows to about ₹2.17 crore. With 20% (about ₹43.4 lakh) used for an annuity at 6%, the illustrative pension is about ₹21,713 a month and up to about ₹1.74 crore can be taken as a lump sum.
What it helps with
- Projects the corpus and the exit split together.
- Shows an illustrative monthly pension.
- Shows the corpus in today's money.
- Applies different rules for normal and premature exit.
What it does not include
- NPS returns are market-linked and the annuity rate depends on the insurer and plan chosen.
- Tax benefits, fund charges and changes in asset mix are not modelled.
- Exit rules are set by PFRDA and change; check the current rules before exit.
- The result is an estimate, not a guarantee.

Common questions.
Is the full NPS corpus paid as a lump sum?
The permitted lump sum and minimum annuity allocation depend on the exit type, vesting period and corpus under the current PFRDA exit rules.
Is the pension shown guaranteed?
No. Both NPS investment returns and the annuity rate used to illustrate pension are assumptions, not guarantees.
What is a NPS Calculator?
It is an educational tool that applies the disclosed NPS projection method to the assumptions you enter.
Are the results guaranteed?
No. Results are estimates, not forecasts, approvals, quotations or guarantees.
Why should I change the assumptions?
Testing conservative and optimistic inputs exposes uncertainty instead of hiding it behind one number.
Does it include tax and fees?
Only when a tax or fee is shown as an explicit input or result. Otherwise it is excluded.
How accurate is the calculator?
The mathematics follows the stated methodology, while real outcomes depend on rates, timing, rules, fees and circumstances.
Can I use this result as financial advice?
No. Use it for education and scenario comparison, then verify decisions with official documents or a qualified professional.
Why is inflation shown?
Inflation translates a future amount into approximate present-day purchasing power. The default 6% is editable and is not a forecast.
How often should I recalculate?
Recalculate when rates, income, contributions, rules, goals or repayment terms change.
Can the result differ from a bank or platform?
Yes. Institutions may use different compounding dates, rounding, charges and eligibility rules.
Is my data uploaded?
No. Calculations run locally in your browser and the input values are not sent to a calculation server.
