NPS Calculator

It depends on four things: how much you invest, for how long, the return you earn, and how much of the corpus you use to buy an annuity. For example, ₹15,000 a month from age 30, raised by 5% a year, at an 8% return grows to about ₹3.59 crore by 60. If all of it buys an annuity at 5.5%, the pension is about ₹1,64,600 a month, worth roughly ₹28,700 in today's money at 6% inflation. If only the minimum 20% buys the annuity, the pension is about ₹32,900 a month and you take about ₹2.87 crore as a lump sum.

PFRDA amended the NPS exit regulations in December 2025. For non-government subscribers (All Citizen and Corporate models):

• Corpus above ₹12 lakh: up to 80% as a lump sum, at least 20% must buy an annuity.
• Corpus above ₹8 lakh and up to ₹12 lakh: up to ₹6 lakh as a lump sum and the rest through systematic withdrawals over at least six years or an annuity, or the 80:20 split.
• Corpus of ₹8 lakh or less: you can withdraw the full amount.

Earlier, the split was 60% lump sum and 40% annuity. Government sector subscribers are not covered by this calculator: their annuity share rules are different.

Up to 60% of the corpus is tax-free under current income tax rules. The new rules let you withdraw up to 80%, but the extra 20% above the tax-free limit is taxed at your slab rate unless the law changes. The pension from the annuity is also taxable as income every year. The calculator splits the lump sum into its tax-free and taxable parts.

If you want ₹50,000 a month in today's money and you are 30, retiring at 60, you need a pension of about ₹2.87 lakh a month at 6% inflation. With all the corpus buying an annuity at 5.5%, that needs a corpus of about ₹6.27 crore. At an 8% return you get there by investing about ₹26,200 a month now and raising it by 5% every year. Use the "How much should I invest?" mode to work it out for your own age and target.

The annuity rate is the yearly pension an insurer pays as a percentage of the money you give it. At 5.5%, ₹1 crore buys a pension of ₹5.5 lakh a year, about ₹45,800 a month. Insurers usually quote about 5 to 7% at 60. Plans that return the purchase price to your family after you die pay less than plans that do not. The rate is fixed when you buy, so the calculator uses one rate for the whole pension.

It depends on your asset mix. Equity-heavy NPS schemes have historically returned more than government bond schemes, with more ups and downs. The calculator uses 8% a year as a moderate long-term assumption. Try 10% and 6% as well to see a range rather than trusting one number. Returns are not guaranteed.

Because of inflation over the years until you retire, and because an annuity pays a fixed amount. At 6% inflation, prices roughly double every 12 years, so a pension 30 years away buys about a sixth of what the same rupees buy today. After you retire the pension stays the same while prices keep rising. That is why many people take part of the corpus as a lump sum and invest it for growth instead of putting everything in an annuity.

Yes. Under current PFRDA rules you stay in NPS after 60 unless you ask to exit, and you can keep contributing until 85. Set the retirement age in the assumptions to see how a few extra years change the corpus and the pension.

1. Your monthly investment goes in at the start of every month and grows at the expected return, converted to an equivalent monthly rate.
2. The monthly amount rises by your yearly step-up percentage once a year.
3. At retirement, the share you choose buys an annuity, and the monthly pension is that amount times the annuity rate, divided by 12.
4. The rest is your lump sum, split into the tax-free 60% of the corpus and any taxable amount above it.
5. In the invest mode the same steps run in reverse, starting from the pension you want.
