NPS Pension Scheme Calculator (India)
Estimate your retirement corpus, lump-sum withdrawal, and expected monthly pension from National Pension System (NPS) contributions.
What is the NPS Pension Scheme?
The National Pension System (NPS) is a government-backed retirement savings scheme in India designed to help individuals build a retirement corpus through disciplined, long-term investing. You contribute periodically during your working years, and your money gets invested in market-linked assets like equity, corporate debt, and government securities.
At retirement (or superannuation), a part of your corpus can be withdrawn as a lump sum, and the remaining part is used to buy an annuity that pays regular pension income. This calculator helps you project those outcomes in advance.
How this NPS calculator works
This tool uses monthly compounding to estimate growth of your NPS corpus. It factors in:
- Your current age and retirement age
- Current NPS corpus
- Monthly contribution and annual step-up in contribution
- Expected annual return during accumulation
- Portion of corpus used for annuity purchase
- Expected annuity payout rate
- Inflation for today-value estimates
Calculation logic (simplified)
- Corpus grows every month based on expected annual return.
- Monthly contribution is increased once every year by step-up percentage.
- At retirement: Annuity Corpus = Total Corpus × Annuity %
- Lump Sum = Total Corpus − Annuity Corpus
- Monthly Pension = (Annuity Corpus × Annuity Rate) ÷ 12
Why contribution step-up matters
A small annual increase in your NPS contribution can significantly improve your final corpus. As income rises over time, increasing contributions by even 5% to 10% annually helps align retirement savings with inflation and lifestyle growth.

How to use this calculator effectively
- Start with realistic return assumptions (not overly optimistic).
- Try two or three scenarios: conservative, moderate, aggressive.
- Compare pension output with your expected post-retirement expenses.
- Adjust monthly investment and step-up rate until target pension is achieved.
- Review your projections yearly as salary, goals, and market conditions change.
Important assumptions and limitations
- Returns are assumed constant for estimation; actual market returns vary.
- Annuity rates are assumed fixed; real market annuity rates may differ at retirement.
- This is an estimate tool, not a guarantee of future benefits.
- Charges, taxes, and withdrawal rules may affect final payouts.
Frequently asked questions
1) Can I withdraw 100% of NPS corpus at retirement?
Under standard NPS exit rules, a minimum portion is generally used to purchase annuity (commonly at least 40% for normal exit). Specific rules and exceptions may apply based on corpus amount and prevailing regulations.
2) What is a good return assumption for NPS?
Many planners use 8% to 11% as a planning range for long-term projections, depending on asset allocation and risk profile. Conservative planning typically uses lower assumptions.
3) Is monthly pension from annuity inflation-adjusted?
Basic annuity options usually offer fixed payouts, while inflation-indexed options may have different payout structures and rates. Review annuity options carefully before retirement.
Final takeaway
The best NPS strategy is simple: start early, invest consistently, step up contributions regularly, and review annually. Use the calculator above to build a realistic retirement plan and close any pension gap while you still have time.
