National Pension System (NPS) Calculator: Complete Retirement & Pension Planning Guide
The National Pension System (NPS) is India's flagship voluntary, government-sponsored retirement pension scheme regulated by the Pension Fund Regulatory and Development Authority (PFRDA). NPS is built to accumulate a retirement corpus over your working years, and combines unusually low fund management costs with market-linked asset allocation and unmatched tax deductions under Section 80CCD. Our free NPS calculator computes your retirement corpus, tax-free lump sum withdrawal, annuity investment, and projected monthly pension.
How NPS Corpus and Monthly Pension are Calculated
Your monthly contributions are invested across chosen asset classes and compounded monthly until your retirement age (default 60 years, extendable up to 75 years). At superannuation:
- Lump-Sum Withdrawal (Up to 60%): You can withdraw up to 60% of the accumulated corpus completely 100% tax-free.
- Mandatory Annuity Purchase (Minimum 40%): At least 40% of the corpus must be invested with an IRDAI-approved Annuity Service Provider (ASP like LIC, HDFC Life, SBI Life) to generate a guaranteed monthly pension for life.
- Monthly Pension Formula: (Annuity Corpus × Annuity Interest Rate) / 12. At a benchmark annuity rate of 6.0%–6.5%, every ₹1 Crore in annuity purchases delivers ₹50,000 to ₹54,000 in monthly lifelong pension.

Understanding NPS Asset Allocation: Active Choice vs Auto Choice
- Active Choice: You decide your asset allocation across Equity (Asset Class E - max 75% up to age 50), Corporate Bonds (Asset Class C), Government Securities (Asset Class G), and Alternative Assets (Asset Class A - max 5%).
- Auto Choice (Lifecycle Funds): Automatically rebalances your asset allocation based on your age:
- Aggressive (LC75): 75% equity exposure up to age 35, gradually reducing to 15% by age 55.
- Moderate (LC50 - Default): 50% equity exposure up to age 35, gradually tapering down to 10%.
- Conservative (LC25): 25% equity exposure up to age 35, tapering down to 5%.
