NPS Calculator
Calculate your NPS corpus at retirement, monthly pension, and lump sum withdrawal based on monthly contributions.
About the NPS Calculator
NPS (National Pension System) is India's government-backed retirement savings scheme regulated by PFRDA. It works like a long-term mutual fund with a pension twist - you contribute monthly into a market-linked corpus across equity (E), corporate bond (C), and government securities (G) funds. At retirement (age 60), you withdraw up to 60% as a tax-free lump sum and use the remaining minimum 40% to buy an annuity that pays you a fixed monthly pension for life.
Total Corpus
Projected NPS balance at your retirement age based on monthly contribution and return.
Monthly Pension
Fixed income for life from the annuity portion - guaranteed by an IRDAI-regulated insurer.
Tax-free Lump Sum
Up to 60% of corpus withdrawn at retirement with zero income tax.
Triple Tax Benefit
80CCD(1), extra 80CCD(1B) ₹50K, and 80CCD(2) for employer contributions - unmatched by any other instrument.
NPS Corpus and Pension Calculation
Corpus at 60 = FV(monthly return, months, monthly contribution) · Monthly pension = (Annuity corpus × Annuity rate) / 12
Monthly return = Annual return / 12 / 100 · Lump sum = (100 - annuity %) of corpus, tax-free · Annuity corpus = annuity % of total corpus · Monthly pension = Annuity corpus × Annuity rate / 12
Worked Example
₹10,000/month from age 30 to 60, NPS equity option at 12% return, 40% annuity at 6.5%
Corpus at 60 ≈ ₹3.5 Cr · Tax-free lump sum (60%) ≈ ₹2.1 Cr · Monthly pension (6.5% on ₹1.4 Cr) ≈ ₹75,800/month
Tips & Insights
- 1
Section 80CCD(1B) gives an additional ₹50,000 deduction exclusively for NPS - above and beyond the shared ₹1.5L 80C limit. In the 30% bracket, this saves ₹15,000 per year in tax.
- 2
Active Choice with 75% equity (E fund) is the highest-return option for investors under 50. NPS equity funds have delivered 12-14% CAGR over 10 years by investing in Nifty 50 and Sensex stocks.
- 3
If your total NPS corpus at age 60 is below ₹5 lakh, you can withdraw the entire amount as a lump sum without being required to buy an annuity.
- 4
Partial withdrawal (up to 25% of your own contributions) is allowed after 3 years for education, marriage, first home purchase, or critical illness - up to 3 times during your NPS tenure.
- 5
Employer NPS contributions under 80CCD(2) (up to 14% of salary for govt, 10% for private) are deductible with no ceiling - and this benefit is available even under the new tax regime.
- 6
Choose a joint-life annuity so your spouse continues to receive the monthly pension after your death. A 'return of purchase price' option also returns the annuity corpus to your nominees.
- 7
Tier II NPS account has no lock-in and can be redeemed anytime - it works like a liquid mutual fund. Government employees get a tax deduction on Tier II contributions too under Section 80C.
- 8
Annuity income in retirement is taxable as salary income. Plan your annuity size keeping in mind that a large monthly pension could push you into a higher tax bracket after 60.
Why this matters for you
NPS offers the most tax-efficient retirement investing available in India. No other instrument combines an upfront deduction (80CCD), an exclusive additional deduction (80CCD(1B) for ₹50,000 more), a tax-free employer match (80CCD(2)), tax-deferred compounding for decades, and a 60% tax-free lump sum at the end. For someone in the 30% bracket investing ₹10,000 per month, the after-tax cost is only ₹7,000 while the full ₹10,000 compounds. That 43% extra compounding principal makes an enormous difference over 30 years.
NPS solves a behavioral problem that most retirement savers eventually face: the temptation to spend the corpus. The mandatory lock-in until 60 and the requirement to buy an annuity with at least 40% of the corpus ensures that even disciplined savers who accumulate a large balance cannot completely drain it at retirement. This is particularly valuable for the self-employed and business owners who lack a pension and have no employer-mandated retirement savings.
The annuity criticism - that 6-7% annuity rates are low - misses the point. The annuity is not an investment; it is longevity insurance. A retiree who lives to 90 will collect pension for 30 years on an annuity bought at 60, making the effective lifetime return far higher than 6.5%. The lump sum portion (60% of corpus) can be invested in diversified mutual funds or PPF to maintain growth in retirement while the annuity provides a guaranteed income floor that never runs out.
