NPS Calculator
RetirementThe National Pension System builds a market-linked retirement corpus. At retirement, at least 40% must buy an annuity for a lifelong pension while up to 60% is a tax-free lump sum.
In short: The NPS Calculator is a free online tool that lets you project your National Pension System corpus, lump sum and monthly pension at retirement — instantly, with charts, a worked example and the exact formula.

How it works
- Your monthly contributions are invested across equity and debt and compound until retirement.
- At retirement, at least 40% of the corpus must be used to purchase an annuity that pays a regular pension.
- The remaining up to 60% can be withdrawn as a tax-free lump sum.
Examples
₹10,000/month from age 30 to 60 at 10% p.a.
Builds a corpus of roughly ₹2.2 crore — about ₹1.3 crore lump sum and a monthly pension near ₹44,000.
Understanding the NPS Calculator
What the National Pension System offers
The National Pension System (NPS) is a low-cost, government-regulated retirement scheme that builds a market-linked corpus over your working life. You contribute regularly to a Tier I account, the money is invested across equity, corporate bonds and government securities, and it compounds until you turn 60. Because charges are among the lowest of any Indian investment product, more of your return stays invested.
At retirement, the corpus splits in a fixed way: up to 60% can be withdrawn tax-free as a lump sum, while at least 40% must buy an annuity that pays a lifelong monthly pension. This mandatory annuitisation is what makes NPS a pension product rather than a plain mutual fund.
The tax advantage
NPS carries a tax break no other instrument matches. Alongside the ₹1.5 lakh limit under Section 80C, you can claim an additional ₹50,000 under Section 80CCD(1B). Salaried employees can go further: employer contributions of up to 14% of basic salary are deductible under 80CCD(2) and, from FY 2024-25, this higher limit applies to private employees under the New regime too.
- The 60% lump sum at 60 is fully tax-free.
- The monthly pension is taxed as income at your slab rate.
- If your corpus is ₹5 lakh or less at 60, you can withdraw all of it without buying an annuity.
Choosing how it is invested
You control the risk. Under Active Choice you set your own split, with equity capped at 75%; under Auto Choice the equity share tapers automatically as you age. You also pick from registered pension fund managers and can switch if one underperforms.
- Young investors benefit from a higher equity allocation and decades of compounding.
- A ₹10,000 monthly contribution from age 30 to 60 at 10% can build a corpus near ₹2.2 crore.
- Premature exit before 60 is restrictive: 80% must be annuitised and only 20% withdrawn.
The trade-off is a long lock-in and a modest annuity rate — often around 6% — that may lag inflation over a long retirement. Used deliberately, though, NPS pairs a rare tax deduction with disciplined, low-cost, equity-linked saving, making it a strong complement to EPF and PPF in a retirement plan.
Pros
- Extra ₹50,000 deduction under 80CCD(1B) on top of the ₹1.5 lakh 80C limit.
- One of the lowest-cost pension products in India, keeping more of your returns.
- Market-linked equity exposure has historically delivered 9–11% blended long-term returns.
- 60% of the corpus can be withdrawn tax-free at retirement.
- Employer contributions of up to 14% of basic are deductible under 80CCD(2).
Cons
- At least 40% of the corpus must buy an annuity, whose pension is taxed at your slab rate.
- Long lock-in until age 60 with limited premature-withdrawal options.
- Annuity rates (around 6%) are modest and can lag inflation over a long retirement.
- Returns are not guaranteed and depend on your chosen asset allocation and fund manager.
Tips
- 1Use the additional ₹50,000 under 80CCD(1B) every year — it is a deduction no other product offers.
- 2Opt for a higher equity allocation when young to maximise long-term compounding.
- 3Route employer contributions through NPS under 80CCD(2) for tax-free retirement savings.
- 4Review your pension fund manager’s performance periodically and switch if it lags peers.
- 5Delay annuitising the full 40% by staggering withdrawals to manage the tax on your pension.
