NPS Calculator 2026 — Retirement Corpus & Monthly Pension

NPS corpus grows like a SIP — your monthly contributions (employee + employer) are invested in a mix of equity (E), corporate bonds (C), and government securities (G). The corpus is calculated using the future value of SIP formula: FV = P × ((1+r)^n − 1) / r × (1+r), where r is the monthly return rate and n is the number of months. For example, ₹5,000/month for 30 years at 10% blended CAGR grows to approximately ₹1.13 crore.

At retirement (age 60), NPS mandates that at least 40% of your total corpus must be used to purchase an annuity plan from a PFRDA-registered insurer. The remaining 60% can be withdrawn as a lump sum, which is completely tax-free. The annuity corpus generates a monthly pension for life. If the total corpus is below ₹5 lakh, the entire amount can be withdrawn as lump sum.

NPS offers three tax deductions: (1) 80CCD(1): Employee contribution — up to 10% of salary (Basic+DA), within the ₹1.5L 80C limit; (2) 80CCD(1B): Extra ₹50,000 deduction OVER AND ABOVE the ₹1.5L 80C limit — this is the most valuable NPS benefit; (3) 80CCD(2): Employer contribution up to 14% of salary for govt employees, 10% for private — no upper limit and not under 80C. Total possible deduction: ₹2L+ per year.

Asset Class E (Equity): Invests in listed equities; historical returns ~12% CAGR — highest return, highest risk; capped at 75%. Asset Class C (Corporate Bonds): Invests in corporate debt; ~8% CAGR — moderate risk. Asset Class G (Government Securities): Gilt funds; ~7% CAGR — lowest risk. For younger investors (under 40), higher equity allocation (50–75%) is recommended. Active Choice lets you set allocation manually; Auto Choice (Lifecycle Fund) automatically reduces equity as you age.

Partial withdrawal (up to 25% of employee contributions) is allowed after 3 years for specific purposes: higher education, marriage of children, house purchase, or critical illness. Early exit before 60: 80% must be used for annuity (only 20% lump sum) — this is less favourable. After 60, you can defer withdrawal up to age 75. If you die before 60, the entire corpus goes to the nominee as lump sum with no annuity requirement.

NPS Tier 1 is a mandatory pension account with tax benefits and restrictions. Contributions qualify for deductions under 80CCD(1), 80CCD(1B), and 80CCD(2). Withdrawals are restricted until age 60 (with limited partial withdrawal after 3 years). Tier 2 is a voluntary savings account with no lock-in — you can withdraw anytime like a mutual fund. However, Tier 2 has no tax benefits under 80CCD (except for government employees who get 80C benefit on Tier 2 with a 3-year lock-in). Tier 2 requires an active Tier 1 account. For most investors, Tier 1 is the core pension tool; Tier 2 is useful only if you want the same low-cost NPS fund management without lock-in restrictions.

At age 60, you have several options: (1) Withdraw up to 60% of the corpus as a tax-free lump sum and use the remaining 40% (minimum) to buy an annuity from a PFRDA-empanelled insurer. (2) If total corpus is below ₹5 lakh, you can withdraw 100% as lump sum. (3) You can defer the withdrawal wholly or partially until age 75 — the corpus continues to grow tax-free. (4) You can withdraw the 60% lump sum in instalments over 10 years (up to age 75) instead of taking it all at once. The annuity portion generates a taxable monthly pension for life, and the annuity rate (typically 5–7%) depends on the insurer and the type of annuity plan you choose.

Auto Choice is a default asset allocation strategy that automatically adjusts your equity-debt mix based on your age. Three lifecycle options exist: Aggressive (LC-75): starts with 75% equity up to age 35, then reduces equity by ~5% every year until it reaches 15% at age 55. Moderate (LC-50): starts with 50% equity, tapering down to 10%. Conservative (LC-25): starts with 25% equity, reducing to 5%. If you don't choose Active Choice, the default is Moderate (LC-50). Auto Choice is ideal for investors who want a hands-off approach. However, younger investors (under 35) may prefer Active Choice with 75% equity allocation to maximise growth, especially since NPS has a 20–30 year horizon.

Under Section 80CCD(2), your employer's NPS contribution is deductible up to 14% of your salary (Basic + DA) for government employees and 10% for private sector employees. This deduction is OVER AND ABOVE the ₹1.5L 80C limit and the ₹50K 80CCD(1B) limit. For example, if your Basic + DA is ₹8L/year and your private employer contributes 10% (₹80K), that entire ₹80K is tax-free for you. Many companies now offer NPS as part of the salary restructuring — opting for it can save ₹25K–40K in tax annually at the 30% slab. Ask your HR to restructure your CTC to include NPS employer contribution if not already offered.

The 60% lump sum withdrawal from NPS is completely tax-free (since Budget 2019). However, the monthly pension received from the 40% annuity is fully taxable as income under 'Income from Other Sources' at your applicable slab rate. There is no standard deduction or exemption on annuity income. This means if your annual annuity pension is ₹4.8L and you are in the 30% tax bracket, you pay approximately ₹1.44L in tax per year on it. To mitigate this, some retirees choose to defer NPS withdrawal to age 75, allowing the corpus to grow further. Also, choosing a higher lump sum (60%) and investing it in tax-efficient instruments like equity mutual funds can be more tax-efficient than a higher annuity.

NPS and PPF serve different roles. NPS invests in equity, corporate bonds, and government securities with market-linked returns (historically 9–12% CAGR for balanced allocation), while PPF offers a fixed 7.1% rate with sovereign guarantee. NPS has a unique tax advantage via 80CCD(1B) (₹50K extra over 80C), whereas PPF falls within the ₹1.5L 80C cap. PPF has EEE status (fully tax-free maturity), while NPS annuity income is taxable. PPF lock-in is 15 years (partial withdrawal from year 7), NPS locks in until age 60. For aggressive retirement planning, NPS with 50–75% equity allocation can generate a significantly larger corpus than PPF over 25–30 years. Ideally, use both: NPS for the extra ₹50K deduction and higher growth potential, PPF for guaranteed tax-free returns and as the debt anchor of your retirement portfolio.

Yes, PFRDA allows you to change both. You can switch your Pension Fund Manager (PFM) once per financial year at no cost. Currently there are 10 PFMs including SBI, LIC, HDFC, ICICI, Kotak, and Aditya Birla. You can also change your asset allocation (E/C/G split) or switch between Active Choice and Auto Choice up to 4 times per financial year. Changes are processed within 3–4 working days. Review your fund manager's performance annually using PFRDA's published returns data. If your current PFM has consistently underperformed peers by 1–2% CAGR, switching can materially impact your retirement corpus over 20–30 years.
