NPS Calculator
Project your NPS corpus at 60, the tax-free lump sum and your monthly pension from regular contributions.
About this calculator
The National Pension System (NPS) is a government-backed retirement scheme where you invest every month until age 60 and build a corpus for your retirement. This free NPS calculator projects that corpus, the tax-free lump sum you can withdraw, and the monthly pension your annuity would pay.
How it works
Contributions are compounded monthly until 60. At retirement, part of the corpus is taken as a lump sum and the rest buys an annuity. Your monthly pension is that annuity amount multiplied by the annuity rate, divided by twelve.
Worked example
Investing ₹5,000/month from age 30 at 9% gives a corpus of roughly ₹1.76 crore at 60. Using 40% for an annuity at 6% yields about ₹35,000 a month in pension, with the remaining ₹1.05 crore taken tax-free.
Compare with other long-term options like the PPF calculator or a SIP calculator for mutual funds.
Why use this NPS calculator
Corpus and pension together
It grows your monthly contribution to age 60, then splits the corpus into the tax-free lump sum and the annuity that funds your monthly pension.
Models the annuity choice
Adjust the share used to buy an annuity and its rate to see how your pension changes — the decision that drives retirement income.
Extra tax deduction in view
NPS offers an additional 80CCD(1B) deduction beyond 80C, making the projected corpus more tax-efficient than it first looks.
Common use cases
- Estimate the monthly pension your NPS will provide at 60
- See how starting five years earlier grows the corpus
- Balance the lump sum vs annuity split for your needs
- Plan NPS alongside EPF and PPF for total retirement income
Frequently asked questions
Your monthly contributions grow with compound interest until you turn 60. The calculator uses the standard future-value formula for a monthly investment, so the corpus depends on how much you invest, for how long and the expected annual return.
At 60 you can withdraw up to 60% of the corpus as a tax-free lump sum. The remaining 40% (or more, if you choose) must be used to buy an annuity that pays your monthly pension.
NPS returns depend on your equity-debt mix. Historically balanced NPS funds have delivered roughly 9–11% a year, but returns are market-linked and not guaranteed.
The 60% lump sum is tax-free. The monthly annuity pension is added to your income and taxed at your slab rate in the year you receive it.
