NPS Calculator

What is NPS?

The National Pension System (NPS) is a government-regulated, market-linked retirement scheme open to any Indian citizen and NRI aged 18 to 70. Regulated by the PFRDA, your money is managed by professional pension fund managers across equity, corporate bonds and government securities at some of the lowest fund-management charges in the world (around 0.09% a year). Because the costs are so low and the corpus compounds untouched for decades, even a modest monthly contribution can build meaningful retirement wealth by the time you turn 60.

Tier I vs Tier II accounts

NPS has two account types, and it helps to know which one you are actually funding:

• Tier I is the core retirement account. It is locked until age 60, carries all the tax deductions below, and is subject to the 40% annuity rule at exit. This is the account this calculator models.
• Tier II is a voluntary add-on with no lock-in and, for most subscribers, no tax benefit. It behaves like a low-cost mutual fund you can exit any time, so it suits medium-term goals rather than pension planning.

You need an active Tier I account before you can open Tier II.

How your money is invested

NPS spreads contributions across three main asset classes: E (equity — mostly index and large-cap stocks), C (corporate bonds) and G (government securities and gilts). A small slice of A (alternative assets) is also allowed. You control the mix in one of two ways:

• Active choice: you set your own split, with equity capped at 75% up to age 50 and tapering after that. Best if you are comfortable managing risk yourself.
• Auto choice (lifecycle funds): the equity share is decided by your age and glides down automatically — Aggressive (LC75) starts near 75% equity, Moderate (LC50) at 50% and Conservative (LC25) at 25%, each reducing as you approach 60.

More equity generally means higher long-term returns with sharper short-term swings. The return field in this calculator lets you test each stance — compare a conservative 8% against an aggressive 11% and watch the corpus move.

Projected corpus by portfolio

Here is how a ₹5,000 monthly contribution from age 30 to 60 (₹18 lakh invested over 30 years) could grow under different return assumptions, keeping the default 40% annuity at a 6% annuity rate:

The gap between 8% and 11% is nearly ₹67 lakh on the very same ₹18 lakh invested — a reminder of how powerfully small differences in return compound over three decades. These figures are illustrative; NPS returns are market-linked and never guaranteed.

Working backwards: what does a ₹30,000 or ₹50,000 pension cost?

Most people arrive with a target income rather than a contribution in mind. Working the calculation backwards is more useful, and it exposes just how much your starting age matters. The table below shows the monthly contribution required to reach each pension, assuming a 10% return while working, 40% of the corpus used to buy an annuity, and a 6% annuity rate.

The numbers are stark. A ₹50,000 pension costs ₹6,600 a month if you start at 25 and ₹59,900 if you start at 45 — nine times as much for a twenty-year delay. Nothing about the target changed; only the number of years available for compounding did. This is the single strongest argument for opening a Tier I account early even with a token contribution.

Two caveats before you rely on these figures. The annuity rate is whatever the market offers on the day you retire, not something you can lock in decades ahead. And the pension is a flat rupee amount for life — it does not rise with inflation, so a ₹50,000 pension starting in 30 years will buy far less then than ₹50,000 buys today. Check that erosion with the inflation calculator before settling on a target.

What happens at 60?

• Up to 60% of the corpus can be withdrawn as a completely tax-free lump sum.
• At least 40% must buy an annuity — an insurance product that pays you a monthly pension for life. This pension is taxable as income in the year you receive it.
• If the total corpus is under ₹5 lakh, you may withdraw all of it and skip the annuity entirely.

You are not forced to exit at 60. PFRDA lets you defer the lump-sum withdrawal, keep contributing, or continue the account up to age 75 — useful if you are still working or want the corpus to compound longer. You can also take the tax-free portion as a systematic lump-sum withdrawal spread over several years rather than a single payout.

NPS tax benefits

NPS is one of the most tax-efficient retirement products in India, with three separate sections:

• 80CCD(1): your own contribution, within the ₹1.5L 80C limit (old regime).
• 80CCD(1B): an extra ₹50,000 deduction over and above 80C (old regime) — exclusive to NPS and the reason many salaried investors open an account.
• 80CCD(2): your employer's contribution, deductible up to 10% of basic salary plus DA (14% for government staff). This is available in both regimes, and for private-sector employees the new-regime ceiling was raised to 14% — making it one of the few deductions still worth having under the new regime.

Because the annuity income is taxed at your slab, it is worth estimating your retirement-year tax with the Income Tax Calculator before deciding how much to annuitise. For a full breakdown of each NPS deduction — and which one still works under the new regime — read our guide: NPS tax benefits explained.

Choosing an annuity

At 60 the mandatory 40% buys a pension from an IRDAI-registered annuity service provider. The common options are:

• Annuity for life: the highest monthly pension, but payments stop when you die.
• Life annuity with return of purchase price (ROP): a lower pension, but your nominee gets the annuity corpus back — popular for leaving an estate.
• Joint-life annuity: continues paying your spouse after you, usually with ROP — sensible for a single-income household.

A life-only option or a higher annuity rate lifts the monthly pension but changes what your family finally receives. Adjust the annuity rate and annuity percentage above to compare outcomes.

NPS vs EPF, PPF and SIPs

NPS works best alongside your other long-term savings rather than as a replacement for them. Compare the guaranteed, tax-friendly options with the EPF Calculator and PPF Calculator, or project flexible equity investing with the SIP Calculator and Lumpsum Calculator — then decide how much of your retirement plan each one should carry.
