What Is NPS Calculator?
The NPS Calculator is a free online tool that estimates your retirement corpus, tax-free lump sum withdrawal, and estimated monthly pension based on your NPS contributions. It accounts for your current age, retirement age, monthly contribution, expected return rate, annuity purchase percentage, and annuity rate — giving you a complete two-stage retirement projection. NPS is regulated by PFRDA and backed by the Government of India, making it one of India's most trusted and tax-efficient retirement vehicles.
How NPS Calculator Helps You
NPS's dual-output nature — lump sum plus monthly pension — makes retirement planning complex without a calculator. This tool makes it simple and actionable.
- Project your total NPS corpus at retirement based on current age, contribution, and expected return
- See your tax-free lump sum withdrawal amount (up to 60% of corpus — fully exempt at age 60)
- Calculate your estimated monthly pension from the annuity portion (minimum 40% of corpus)
- Understand the impact of increasing your monthly contribution on your final retirement income
- Check whether your projected monthly pension covers your current lifestyle expenses
How Does NPS Calculator Work?
NPS calculation happens in two stages. Stage 1 — Corpus Accumulation: A = P × [(1 + r/12)^(n×12) − 1] / (r/12) × (1 + r/12), where P is monthly contribution, r is annual return rate, and n is tenure in years. Stage 2 — Pension Conversion: Monthly Pension = (Annuity Corpus × Annuity Rate) ÷ 12. For example, ₹5,000/month for 30 years at 10% p.a. builds a corpus of approximately ₹1.13 crore. At 40% annuitised at 6%: Lump Sum = ₹68 lakhs (tax-free) | Annuity Corpus = ₹45 lakhs | Monthly Pension = ₹22,500.

Frequently Asked Questions
For a Tier I NPS account, the minimum annual contribution is ₹1,000 with no maximum limit. For maximum tax benefit, contribute at least ₹2 lakhs per year — ₹1.5L under 80CCD(1) within Sec 80C, plus ₹50,000 additional under 80CCD(1B). Employer contributions under 80CCD(2) are deductible over and above these limits.
Yes — this is the most commonly misunderstood NPS tax rule. The 60% lump sum at retirement is completely tax-free. However, the monthly pension you receive from the annuity is added to your taxable income each year and taxed at your applicable slab rate. It is not tax-free income. Plan your annuity corpus size accordingly.
Premature exit before age 60 requires you to use at least 80% of the corpus to purchase an annuity — only 20% can be withdrawn as a lump sum, which is also taxable. This makes NPS a strong long-term commitment. If your total corpus is below ₹2.5 lakhs, you can withdraw the full amount.
For a balanced NPS portfolio (50% equity, 30% corporate debt, 20% govt securities — Auto Choice Moderate), 9%–10% p.a. is a reasonable long-term estimate. For aggressive equity-heavy allocation (75% equity), 10%–11% may be used. Conservative investors with high debt allocation should use 7%–8%.
Yes. You can increase, decrease, or modify NPS contributions at any time. Many investors start small and increase by 10%–15% annually alongside salary increments. A step-up contribution strategy — starting at ₹3,000/month and increasing 10% each year — builds a significantly larger corpus than a flat contribution over 25–30 years.
