Tax angles
  • Up to 60% of the corpus taken at exit is tax-free; annuity income is taxed at your slab every year.
  • Old regime: own contributions count under 80CCD(1) within ₹1.5 lakh, plus an extra ₹50,000 under 80CCD(1B).
  • Both regimes: employer contributions are deductible — up to 14% of basic in the new regime (10% in the old).
  • Exit before 60 (non-government): 80% must buy an annuity unless the corpus is ₹5 lakh or less.

About the NPS Calculator

The National Pension System (NPS) is a voluntary, market-linked retirement scheme in India. You contribute regularly during your working years, the money grows across equity and debt funds, and at retirement a portion must be used to buy an annuity that pays you a monthly pension while the rest can be withdrawn as a tax-free lump sum.

This calculator grows your monthly contributions using the same future-value logic as a SIP up to your retirement age, then splits the corpus. Since PFRDA's December 2025 overhaul, non-government subscribers must put at least 20% of the corpus into an annuity (government subscribers 40%), with full withdrawal allowed for a corpus up to ₹8 lakh; you can raise the annuity share. The estimated monthly pension is the annuity investment multiplied by the assumed annuity rate, divided by twelve. Adjust the expected return, annuity portion and annuity rate to see the trade-off between a bigger lump sum and a larger pension.

All figures are estimates. Actual fund returns, the annuity rate offered by insurers at retirement, and NPS rules can all differ from your assumptions. Everything is computed privately in your browser.

Examples

₹5,000/month from age 30 to 60 at 10% → corpus ≈ ₹1.13 crore.
Keep the 20% minimum for annuity at a 6% annuity rate → the largest tax-free lump sum, a smaller pension.
Raise the annuity portion to 100% for a larger pension but no lump sum.

Frequently asked questions

5 answers
How much of the NPS corpus must buy an annuity?
After PFRDA's December 2025 changes, non-government (All Citizen and Corporate) subscribers must use at least 20% of the corpus for an annuity and can take up to 80% as a lump sum. If the corpus is ₹8 lakh or less you can withdraw all of it; between ₹8 and ₹12 lakh up to ₹6 lakh can be taken as a lump sum. Government employees still follow the 60/40 rule.
Is the lump sum taxable?
Up to 60% of the corpus withdrawn at exit is tax-exempt, while the annuity pension is taxed as income each year. Check how any withdrawal beyond 60% is taxed before you exit — rules can change.
What annuity rate should I assume?
Annuity rates depend on the insurer and prevailing interest rates at retirement, often in the 5-7% range. It is only fixed when you actually buy the annuity.
Can I contribute after age 60?
NPS now allows contributions and deferral beyond 60 up to age 75. This tool projects to the retirement age you enter.
Are the returns guaranteed?
No. NPS is market-linked, so the corpus depends on how the equity and debt funds perform. The return you enter is only an assumption.
