NPS Calculator Retirement Corpus & Monthly Pension
Estimate your NPS retirement corpus, tax-free lump sum, and projected monthly pension based on your contribution, age, and expected returns.
minimum 40% mandatory under NPS rules
NPS returns are market-linked and will vary. At retirement, a minimum 40% of the corpus must be used to purchase an annuity; the balance can be withdrawn as a tax-free lump sum.
What Is the National Pension System (NPS)?
the national pension system is a voluntary, long-term retirement savings scheme regulated by the pfrda (pension fund regulatory and development authority) and backed by the government of india. you make regular contributions during your working years, the funds are invested across equity, corporate bonds, and government securities, and at retirement you receive a portion as a tax-free lump sum and the rest as a monthly lifelong pension (annuity).
nps is open to all indian citizens aged 18–70 — salaried employees, self-employed individuals, and non-resident indians. it combines market-linked wealth creation with the discipline of a pension structure, making it one of the most complete retirement tools available in india.
How the NPS Calculator Works
the calculator takes your monthly contribution, current age, expected retirement age, and the anticipated rate of return to project the corpus you will have built by retirement. it then splits that corpus based on the annuity percentage you specify — the annuity portion is locked into a pension plan that pays you every month, and the remainder is withdrawn tax-free as a lump sum.
the projected monthly pension is calculated using a simple annuity yield: annual annuity return divided by 12, applied to the annuity corpus. actual pension amounts will vary by the annuity service provider and plan type chosen at retirement.
NPS Calculator Formula
the projected corpus is calculated using the future value of a regular monthly annuity:
Corpus = C × [ ((1 + r)ⁿ − 1) / r ]
where C = monthly contribution, r = effective monthly return = (1 + annual rate)^(1/12) − 1, and n = total months of contribution.
example — Mr. A, age 25, monthly contribution ₹10,000, retirement at 60, 8% return, 40% annuity at 6% yield:
total months = (60 − 25) × 12 = 420
corpus ≈ ₹1,74,04,640
lump sum (60%, tax-free) ≈ ₹1,04,42,784
annuity corpus (40%) ≈ ₹69,61,856
estimated monthly pension ≈ ₹34,809
How to Use This Calculator
- enter your monthly contribution amount.
- set your current age using the slider.
- set your expected retirement age (default 60; can go up to 70).
- adjust the expected rate of return — nps equity funds have historically returned 9–12%, blended portfolios often 8–10%.
- set the annuity purchase percentage — minimum 40% is mandatory; higher annuity means a larger monthly pension.
- set the expected annuity return (annuity providers typically offer 5–7%).
- the calculator instantly shows your corpus, lump sum, annuity split, and monthly pension estimate.
NPS Account Types: Tier 1 and Tier 2
nps has two account tiers with different rules around withdrawals and tax treatment:
| Feature | Tier 1 | Tier 2 |
|---|---|---|
| Purpose | Primary retirement account | Voluntary savings top-up |
| Withdrawals | Restricted until retirement | Flexible — anytime |
| Lock-in | Till age 60 | None |
| Tax benefit on contributions | Yes (80C + 80CCD(1B)) | No (except govt employees) |
| Minimum contribution | ₹500 per contribution / ₹1,000 per year | ₹250 per contribution |
| Mandatory at opening | Yes | No |
NPS Tax Benefits
in total, a salaried individual can claim up to ₹2 lakh in nps-related deductions per year under the old tax regime. the employer's contribution under 80ccd(2) is also allowed in the new regime.
| Section | Who Benefits | Maximum Deduction |
|---|---|---|
| 80CCD(1) | Employee or self-employed individual | Up to ₹1.5 lakh (within overall 80C limit) |
| 80CCD(1B) | All NPS Tier 1 subscribers | Additional ₹50,000 over and above 80C |
| 80CCD(2) | Salaried employees | Up to 10% of salary (14% for Central Govt employees) |
NPS Withdrawal Rules
nps is designed for long-term retirement accumulation, and withdrawals are governed by specific rules:
- at retirement (age 60): up to 60% of the corpus can be withdrawn tax-free as a lump sum. at least 40% must be used to purchase an annuity for a regular pension. (non-government subscribers can withdraw up to 80% as lump sum from oct 2025 reforms, with only 20% mandatory annuity.)
- premature exit (before age 60): only 20% can be taken as lump sum; 80% must go into an annuity plan.
- partial withdrawal: subscribers can withdraw up to 25% of their own contributions after 3 years for specified purposes — higher education, marriage, medical treatment, house purchase, or start-up capital.
NPS Annuity: How Your Monthly Pension Is Calculated
an annuity is a pension product purchased from an annuity service provider (asp) that pays you a fixed income every month for life. under nps, a portion of your retirement corpus must compulsorily be invested in an annuity.
the monthly pension depends on four factors: the size of the annuity corpus, the annuity rate offered by the asp, your age at retirement (older age = higher annuity rate), and the annuity plan type selected.
common annuity plan types include: lifetime pension for self, joint-life with spouse, return of purchase price on death, and increasing annuity with inflation protection.
How Inflation Affects NPS Planning
a retirement corpus that looks substantial today may not stretch as far two or three decades from now. if monthly expenses are ₹50,000 today and inflation averages 6% annually, the same lifestyle could cost over ₹1.6 lakh a month after 20 years.
this is why long-term nps planning should factor in: inflation-adjusted returns, rising healthcare costs, increased life expectancy, and changing lifestyle needs. the equity component in nps naturally provides some inflation protection, which is one of its structural advantages over purely fixed-return retirement products.
NPS vs EPF vs PPF
here is how nps compares with the two other major retirement savings schemes:
| Feature | NPS | EPF | PPF |
|---|---|---|---|
| Returns | Market-linked (8–12% historical) | Fixed, declared annually (8.25% FY26) | Government-backed fixed (7.1%) |
| Risk | Moderate (equity + debt mix) | Low | Very Low |
| Lock-in | Till retirement | Till retirement / job change | 15 years |
| Pension Income | Yes — mandatory annuity | No | No |
| Equity Exposure | Up to 75% (active choice) | Limited | None |
| Tax on Maturity | 60% lump sum tax-free; annuity taxable | Fully tax-free (5+ yrs) | Fully tax-free |
| Best For | Retirement corpus + lifelong pension | Salaried employees (mandatory) | Safe long-term savings + tax saving |
Strategies to Maximise Your NPS Corpus
- start as early as possible — compounding rewards time above all else. an extra 5 years of contributions can nearly double the corpus.
- increase contributions with salary increments — even a 10% annual step-up in monthly nps contribution dramatically improves the final corpus.
- maintain equity allocation in early years — younger subscribers can allocate up to 75% to equities for higher long-term growth; gradually shift to safer assets as retirement nears.
- use the additional ₹50,000 deduction every year — 80ccd(1b) is over and above 80c; it is often the most tax-efficient ₹50,000 you can invest.
- account for inflation — target a corpus large enough to generate a monthly pension that covers projected future expenses, not today's costs.
