How it works

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funds, and at retirement a portion must be used to buy an annuity that pays you a monthly pension while the rest can be withdrawn as a tax-free lump sum.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. Current rules require at least 40% of the corpus to buy an annuity; you can raise that 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 40% for annuity at a 6% annuity rate → a monthly pension in the tens of thousands.
Raise the annuity portion to 100% for a larger pension but no lump sum.

Frequently asked questions

How much of the NPS corpus must buy an annuity?
Under current rules, at least 40% of the corpus at retirement must be used to purchase an annuity, and up to 60% can be withdrawn as a lump sum.
Is the lump sum taxable?
Currently the lump-sum withdrawal at maturity (up to 60%) is tax-exempt, while the annuity pension is taxed as income when received. 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.
