How the NPS calculator works
Understanding National Pension System calculations and retirement planning.
- Choose Account TypeSelect Tier I for tax benefits and long-term retirement planning, or Tier II for flexible savings without lock-in.
- Determine ContributionDecide monthly contribution amount. Minimum ₹500 for Tier I and ₹250 for Tier II. Higher contributions lead to larger corpus.
- Select Asset AllocationChoose between Auto Choice (age-based allocation) or Active Choice (self-managed allocation) based on your risk appetite.
- Calculate Retirement CorpusUse compound interest formula: FV = PMT × [((1 + r)^n - 1) / r] where PMT is monthly contribution, r is monthly return rate, n is number of months.
NPS formula: Future Value = PMT × [((1 + r)^n - 1) / r]
PMT = Monthly contribution amount · r = Monthly interest rate (Annual rate ÷ 12) · n = Total number of months
Annuity = 40% of corpus (mandatory) · Lump Sum = 60% of corpus (tax-free)
Pro Tip: NPS offers dual tax benefits - deduction on contribution and tax-free lump sum withdrawal. The monthly pension from annuity is taxable as per your income slab.

- PRAN (Permanent Retirement Account Number)
- A unique 12-digit number assigned to each NPS subscriber for tracking contributions and maintaining account records throughout the investment period.
- Annuity
- A financial product that provides regular income after retirement. In NPS, 40% of corpus must be used to purchase annuity for monthly pension.
- Asset Allocation
- Distribution of investments across equity (Class E), corporate bonds (Class C), and government securities (Class G) based on age and risk appetite.

- At retirement, subscribers can withdraw 60% as lump sum (tax-free) and must invest 40% in annuity for monthly pension. Premature exit before 60 has restrictions.
Expert NPS tips
- Start Early for Maximum Benefit: Begin NPS investments in your 20s or early 30s to leverage the power of compounding over 30-40 years for substantial corpus building.
- Maximize Tax Benefits: Contribute up to ₹1.5 lakh under Section 80C and additional ₹50,000 under Section 80CCD(1B) for Tier I to save maximum tax.
- Choose Appropriate Asset Allocation: Younger investors can opt for higher equity allocation (up to 75%) for better returns, while older investors should prefer debt for stability.
- Regular Contribution Increases: Increase your monthly contribution by 10-15% annually or with salary increments to build a larger retirement corpus.
- Monitor and Review Regularly: Review your NPS portfolio annually, check fund performance, and adjust asset allocation based on market conditions and age.
- Plan Annuity Purchase Wisely: Research different annuity providers and options before retirement to ensure the best monthly pension rates for your corpus.
Important: NPS is subject to market risks and regulatory changes. Consult with a financial advisor for personalized retirement planning advice.
Frequently asked questions
How is NPS pension calculated?
At 60, you can withdraw up to 60% of NPS corpus as lump sum (tax-free). The remaining 40% is mandatorily used to buy an annuity for monthly pension. Pension = (40% of corpus × annuity rate) / 12. Annuity rates currently range from 5.5–7% depending on the annuity type chosen.
What is the extra tax deduction under NPS Section 80CCD(1B)?
Over and above the ₹1.5 lakh 80C limit, you can claim an additional deduction of ₹50,000 under Section 80CCD(1B) for NPS Tier I contributions. This is a unique benefit not available with PPF, ELSS, or other investments — making NPS highly tax-efficient under the old regime.
What are the expected NPS returns?
Historical NPS returns (approximate): Equity (E) funds: 12–14% CAGR over 10 years; Corporate Bond (C) funds: 8–9%; Government Bond (G) funds: 7–8%. NPS allows choosing asset allocation. Young investors (below 40) can go 75% equity for higher long-term returns.
Is NPS maturity amount tax-free?
60% of NPS corpus withdrawn as lump sum at maturity (age 60) is completely tax-free. The remaining 40% used to purchase annuity is tax-exempt at purchase, but monthly pension (annuity income) is taxable as per your slab in the year received.
What is the lock-in period for NPS?
NPS Tier I has a lock-in until age 60 (or 3 years, whichever is later for partial withdrawals). Partial withdrawal (up to 25% of own contributions) is allowed after 3 years for specific purposes like higher education, marriage, home purchase, or medical emergency.
What is the difference between NPS Tier I and Tier II?
Tier I is the primary pension account with tax benefits and lock-in until 60. Tier II is a voluntary savings account with no lock-in and no additional tax benefits (except for central government employees). Tier I must be opened before Tier II. Both can invest in equity and debt.
