NPS Calculator: corpus, lump sum and monthly pension (2026 exit rules)
Project your National Pension System corpus at retirement, the lump sum you can withdraw and the monthly pension from the annuity, under PFRDA’s December 2025 exit rules (20% minimum annuity for non-government subscribers, 40% for government). Includes yearly step-up, existing balance and a year-by-year table.
How it works
Corpus = P × [((1 + i)^n − 1) ÷ i] × (1 + i) (contributions at the start of each month; drop the last factor for end of month), i = annual return ÷ 12, n = months · Annuity = corpus × annuity % · Lump sum = corpus − annuity (capped at ₹6 lakh when the corpus is ₹8–12 lakh) · Monthly pension = annuity × annuity rate ÷ 12
The National Pension System invests your monthly contributions in market-linked funds that compound until you exit. This calculator grows each contribution at your expected return, compounded monthly, adds any existing balance and yearly step-up, and then splits the final corpus under the exit rules PFRDA notified on 12 December 2025. At normal exit (age 60, superannuation, or after 15 years in NPS for non-government subscribers), a non-government subscriber must use at least 20% of the corpus to buy an annuity and can take up to 80% as a lump sum; a government subscriber must use at least 40%. If the corpus is ₹8 lakh or less you may withdraw all of it. Between ₹8 lakh and ₹12 lakh the lump sum is capped at ₹6 lakh and the rest is paid through systematic unit redemption over at least 6 years or used for an annuity. A premature exit (before 60 with under 15 years for non-government subscribers, or resignation for government employees) needs at least 80% in an annuity unless the corpus is ₹5 lakh or less. You can stay invested up to age 85. The monthly pension is the annuity amount times the annuity rate divided by 12. Real annuity quotes depend on the insurer, your age and the option you choose, so treat it as an estimate.
Worked example
A non-government subscriber aged 30 invests ₹5,000 at the start of each month until 60 at 10% a year. Over 360 months that ₹18,00,000 grows to a corpus of ₹1,13,96,627, of which ₹95,96,627 is returns. Using 40% (₹45,58,651) to buy an annuity at 6% pays ₹45,58,651 × 6% ÷ 12 = ₹22,793 a month, and the other 60% (₹68,37,976) can be withdrawn as a lump sum. Choosing the new 20% minimum instead would raise the lump sum to ₹91,17,302 and lower the pension to ₹11,397 a month.

Frequently asked questions
How much of the NPS corpus must go into an annuity in 2026?
Under PFRDA’s amendment of 12 December 2025, non-government subscribers (All Citizen and Corporate models) must use at least 20% of the corpus for an annuity at normal exit and can take up to 80% as a lump sum. Government subscribers still need at least 40%. These minimums apply when the corpus is above ₹12 lakh.
Can I withdraw my whole NPS corpus?
Yes, if the corpus is ₹8 lakh or less at normal exit (₹5 lakh or less on a premature exit). Between ₹8 lakh and ₹12 lakh you can take up to ₹6 lakh as a lump sum and receive the rest through systematic unit redemption over at least 6 years, or buy an annuity.
Can I exit NPS before 60?
Non-government subscribers can exit normally after 15 years in NPS even before 60. Leaving earlier is a premature exit: at least 80% of the corpus must buy an annuity unless the corpus is ₹5 lakh or less.
Is the NPS corpus guaranteed?
No. NPS is market-linked, so the corpus depends on the returns of the equity, corporate bond and government bond funds you choose. The expected return you enter is an assumption, not a promise.
Is the NPS lump sum taxable?
Withdrawals up to 60% of the corpus are tax-free, and the annuity pension is taxed as income. The extra lump sum now allowed for non-government subscribers may be taxed differently, so check the current rules or ask a tax adviser.
How long can I stay invested in NPS?
The amended rules let you defer exit and stay invested up to age 85. A later exit gives the corpus more years to grow, which this calculator shows if you raise the exit age.
