Enter Your NPS Details
Fill in your age, contribution, and expected return to estimate your retirement corpus and pension.
An NPS calculator projects the retirement corpus you could build through India's National Pension System — the voluntary, market-linked pension scheme regulated by the PFRDA (Pension Fund Regulatory and Development Authority) — from your current age, monthly contribution, and expected return. Working as a combined NPS maturity calculator, NPS pension calculator, and NPS annuity calculator, it shows not just your projected corpus but how that corpus splits into a lump sum withdrawal and a mandatory annuity purchase at retirement, plus an estimated monthly pension from that annuity.
You enter your current age, planned retirement age (60 to 70, since NPS allows deferred exit up to 70), monthly Tier I contribution, expected annual return during accumulation, and any existing NPS corpus you already hold. Each month, the calculator adds your contribution and compounds the running balance at your expected return, repeating from your current age to your retirement age. At retirement, the corpus is split using your chosen Annuity Purchase % — the calculator enforces the PFRDA-mandated 40% minimum — into an annuity corpus used to buy a pension plan, and a lump sum you can withdraw. The Estimated Monthly Pension then applies your Expected Annuity Rate to that annuity corpus.
Salaried employees and self-employed individuals building a market-linked retirement layer, government and corporate employees enrolled in an employer NPS scheme, anyone deciding how much of their ₹1.5 lakh Section 80C limit plus the extra ₹50,000 under Section 80CCD(1B) to allocate to NPS, and savers who want to see the lump-sum-versus-pension trade-off before committing decades of contributions to a scheme with a mandatory annuitization rule.
NPS is unique among India's major retirement schemes because it is market-linked rather than fixed-return, and because it legally requires you to convert a portion of your savings into a lifetime pension rather than letting you withdraw the full corpus in cash. Understanding the lump sum vs annuity split in advance — and how sensitive your monthly pension is to the annuity rate prevailing at your retirement date — helps you plan realistically rather than assuming your entire NPS balance will be available as cash at exit. This PFRDA-aware NPS calculator also makes it easier to compare NPS against fixed-return options like EPF and PPF, and against a one-time payout like a gratuity, as part of a diversified retirement plan.
Growth is simulated monthly on the running balance, then the corpus is split into a lump sum and an annuity portion at retirement
From current age to projected pension in under a minute
NPS accepts a current age from 18 to 65 and a retirement age from 60 to 70 in this calculator, so start by setting how many years you have left to accumulate.
Enter what you plan to contribute to your Tier I account every month, plus any balance you already hold in Existing NPS Corpus if you're modeling an account you've already started.
This is your assumption for how your chosen equity, corporate debt, and government securities mix will perform — not a guaranteed number. The calculator compounds it monthly on the running balance.
The Annuity Purchase % cannot go below the PFRDA-mandated 40% minimum used by this calculator; a lower entry is corrected automatically. The Expected Annuity Rate determines your estimated monthly pension from that portion.

A 30-year NPS accumulation, from age 30 to the standard retirement age of 60
Suppose a 30-year-old starts an NPS Tier I account, contributing ₹5,000 every month, assuming a 10% expected annual return during accumulation, retiring at 60 with no existing corpus, and purchasing the minimum 40% annuity at an expected annuity rate of 6%.
| At Retirement | Amount | Share of Corpus |
|---|---|---|
| Lump Sum Withdrawal | ₹67,81,500 | 60% |
| Annuity Corpus (buys pension) | ₹45,21,000 | 40% |
| Estimated Monthly Pension | ₹22,605 / month | — |
Explanation: over 30 years, roughly 84% of this projected corpus comes from investment growth rather than the contributions themselves — a reminder of how much time in the market matters for a long-horizon, market-linked scheme like NPS. Because the annuity percentage is kept at the 40% PFRDA minimum, this saver keeps the maximum permitted 60% as a tax-free lump sum, at the cost of a smaller guaranteed monthly pension than a higher annuity percentage would provide.
Higher-annuity comparison: if the same saver instead chose to annuitize 60% of the corpus rather than the 40% minimum, the Annuity Corpus rises to roughly ₹67,81,500 and the Estimated Monthly Pension rises to about ₹33,908/month — but the lump sum withdrawal at retirement drops to roughly ₹45,21,000, illustrating the direct trade-off between a larger one-time lump sum and a larger guaranteed monthly pension.
How your Expected Annual Return assumption changes the growth multiple over a long accumulation period
A useful way to sanity-check an NPS projection over a long accumulation period is the growth share — how much of the final corpus came from investment growth versus your own contributions. This isn't an official PFRDA benchmark, but it's a quick way to see whether your return assumption is producing a realistic outcome for your time horizon.
| Expected Annual Return | Growth Share Over 30 Years (approx.) | Read |
|---|---|---|
| Below 7% | ~65% – 75% of final corpus | A conservative, debt-heavy allocation — steadier, but a smaller growth multiple |
| 7% – 10% | ~75% – 85% of final corpus | A balanced equity/debt mix — the range many long-term NPS investors model |
| Above 10% | ~85% of final corpus or more | A higher-equity allocation — historically strong long-term potential, but with more year-to-year volatility |
For long-horizon savers: the longer your accumulation period, the more your final corpus depends on the return assumption rather than your contribution amount — small changes to Expected Annual Return compound into large differences over 20–30 years, so it's worth modeling a range rather than a single number.
For the annuity decision: compare your Estimated Monthly Pension at the 40% minimum against a higher annuity percentage. A higher percentage locks in more guaranteed monthly income but reduces the tax-free lump sum available at exit — there's no universally "right" split, only one that matches your other retirement income sources.
Risk considerations: this calculator assumes a constant return and a constant annuity rate for simplicity. Real NPS returns fluctuate year to year with market conditions, and the actual annuity rate available at your retirement date depends on prevailing interest rates and the annuity service provider you choose — both can differ meaningfully from the assumptions you enter here.

NPS is market-linked — actual returns, annuity rates, and PFRDA rules (including the mandatory annuity percentage and withdrawal limits) can change.
