How it is calculated
The calculator compounds your monthly contribution at your expected annual return until retirement (annuity-due basis). Under NPS rules, at least 40% of the final corpus must be used to buy an annuity (pension) at age 60, while up to 60% can be withdrawn (currently tax-free). Returns are market-linked and not guaranteed.
Where the deduction sits, and the one that survives the new regime
NPS attracts deductions under three different provisions and keeping them apart matters. Your own contribution under section 80CCD(1) falls inside the ₹1.5 lakh ceiling shared with 80C, so for many people it adds nothing on its own. The additional deduction under 80CCD(1B) is genuinely separate and capped at ₹50,000, taking the old-regime total to ₹2 lakh. The employer's contribution under section 80CCD(2) is outside your limit altogether, and it is the one that matters most now, because it is among the very few deductions that survive in the new regime. For an employee in a higher bracket whose employer offers it, routing part of the package through an employer NPS contribution is often the single largest remaining deduction available under the default regime, and it costs the employer nothing extra if the salary is restructured rather than increased.
Tier I is the retirement account; Tier II is not
The two tiers behave so differently that treating them as versions of the same product causes real confusion. Tier I is the retirement account: contributions attract the deductions described above, and the money is locked until you exit, with partial withdrawal permitted only after a minimum period and only for specified purposes such as higher education, marriage, buying a house or serious illness, and capped as a proportion of your own contributions. Tier II is a voluntary investment account with no lock-in and no deduction for most subscribers — it functions more like an open-ended fund with NPS's low charges, and money can be moved in and out freely. Opening Tier II is optional and requires an active Tier I. If you are choosing NPS for the tax deduction, the deduction lives in Tier I; Tier II is a separate decision made purely on investment merits.
What happens at exit
The exit rules shape whether NPS suits you, so they are worth knowing before you commit rather than at sixty. On normal exit at retirement age, up to 60% of the corpus can be taken as a lump sum and that portion is exempt from tax; at least 40% must be used to buy an annuity from a life insurer. The annuity purchase itself is not taxed, but the pension it pays is taxable as income in the years you receive it — which is the point people most often miss when comparing NPS to other retirement options. Small corpuses below a prescribed threshold can generally be withdrawn in full. On premature exit before retirement age the proportions reverse and a much larger share must go into an annuity. On death, the accumulated corpus is generally payable to the nominee. The annuity requirement is the real trade-off for the deduction.
The choices that actually move the outcome
Two decisions inside NPS affect the final corpus far more than the choice of pension fund manager, which is where most attention goes. The first is your asset allocation. Active choice lets you set the split across equity, corporate bonds, government securities and alternatives yourself, within a cap on the equity share that steps down with age. Auto choice moves you along a predefined glide path from equity into debt as you get older. Over a thirty-year horizon the equity share is the single biggest determinant of the outcome, and a very conservative allocation early on costs more than any charge. The second is simply how early and how consistently you contribute, since compounding rewards duration more than instalment size. Fund managers can be switched, and the allocation reviewed, without exiting — so neither choice is permanent, and reviewing them every few years is worth more than agonising at the outset.
Charges are low, but they are not zero
NPS is among the cheapest managed retirement products available in India, and the low charge structure is a genuine part of its case — over a thirty-year horizon a difference of half a per cent in annual costs compounds into a substantial difference in corpus. But the charges are not nil, and they arrive in several places: a one-time account opening charge, a charge on each contribution collected by the point of presence, an annual asset servicing charge levied by the custodian, and the fund management fee itself, which is capped at a low level. Contributions made through the government's own online route generally attract lower transaction charges than those routed through a bank or distributor, which is worth checking if you contribute regularly. None of this changes the fundamental economics, but comparisons that describe NPS as free are inaccurate, and the difference between contribution channels is within your control.
What the projection cannot know
A retirement projection multiplies a monthly contribution by an assumed rate of return over an assumed period, and every one of those inputs is an estimate rather than a fact. Real returns arrive as a sequence rather than a constant, and the same average produces materially different outcomes depending on when the good and bad years fall. The projection also works in nominal terms, so a corpus that looks large in today's figures buys considerably less in thirty years — the practical fix is to subtract expected inflation from your assumed return and read the result as today's purchasing power. It cannot know what your contributions will actually be, since salaries and priorities change, nor what annuity rates will be at your retirement, which is what ultimately determines the pension the corpus buys. Run it at more than one rate and plan around the conservative figure.
How NPS compares with the alternatives
NPS is not a substitute for the other retirement instruments so much as a complement with a different shape. Provident fund gives a fixed declared return, full liquidity at exit and no annuity requirement, but no equity participation. PPF is similar in character with a fifteen-year horizon and a government-set rate. Equity mutual funds offer full flexibility and no lock-in beyond ELSS, with no compulsory annuity and no deduction under the new regime. NPS sits between them: market-linked returns with an equity share you control, the lowest charges of the group, an additional deduction under the old regime and the employer route that survives the new one — set against a long lock-in and the requirement to annuitise a substantial part of the corpus. The annuity requirement is the honest cost of the tax benefit, and whether it is worth paying depends on how much other liquidity you will have at sixty.
Frequently asked questions
Is the NPS deduction available in the new tax regime?
Your own contributions are not, but the employer's contribution under section 80CCD(2) is — and it is one of very few deductions that survives. For an employee in a higher bracket whose employer offers it, restructuring salary to include it is often the largest remaining deduction under the default regime.
Do I have to buy an annuity with my NPS corpus?
On normal exit at retirement, at least 40% must go into an annuity and up to 60% can be taken as a tax-exempt lump sum. The annuity purchase is not taxed but the pension it pays is taxable as income. On premature exit the proportion required to be annuitised is much higher.
How much of my NPS corpus can I withdraw?
At maturity (age 60), you can withdraw up to 60% as a lump sum (currently tax-free) and must use at least 40% to buy an annuity that pays you a pension.
Are NPS returns guaranteed?
No. NPS is market-linked — returns depend on the equity/debt mix you choose and market performance. The calculator's figure is an estimate, not a guarantee.
Does NPS give a tax benefit?
NPS offers deductions under Sections 80CCD(1), 80CCD(1B) (an extra ₹50,000) and 80CCD(2) for employer contributions, subject to conditions. Verify the current limits with a CA.
