NPS Calculator
Estimate your National Pension System corpus at retirement, how much of it you can take as a lump sum, and the monthly pension the rest will buy. Enter your monthly contribution, your age and an expected return.
More options: exit age, employer contribution, pension
Contributing ₹5,000 a month for 30 years at 10% builds about ₹1.14 Cr by age 60. With a corpus above ₹12 lakh, you can take up to 80% as a lump sum; at least 20% must buy an annuity (pension).
Assumes the same contribution every month and a steady return; actual NPS returns go up and down with the market. The pension is taxable as income. Exit rules are for non-government subscribers (PFRDA, December 2025).

What is NPS?
The National Pension System (NPS) is a government-regulated retirement scheme run by PFRDA. You contribute regularly to a Tier I account; the money is invested in a mix of equity, corporate bonds and government bonds that you choose. When you exit, normally at 60, you can take part of the corpus as a lump sum and must use the rest to buy an annuity, which pays you a monthly pension for life.
How the corpus is calculated
Corpus = M × [(1 + r)n − 1] ÷ r × (1 + r)
- M = monthly contribution (yours plus your employer’s)
- r = expected yearly return ÷ 12 ÷ 100
- n = number of months until you exit
Worked example
₹5,000 a month from age 30 to 60 (360 months) at an assumed 10% a year:
- Corpus at 60 = ₹1,13,96,627, from ₹18,00,000 contributed
- Lump sum (80%) = ₹91,17,301, of which ₹68,37,976 (60% of the corpus) is tax-free and ₹22,79,325 is taxable
- Annuity (20%) = ₹22,79,325, which at 6% pays about ₹11,397 a month
The return matters a great deal over 30 years: at 8% the same contributions give about ₹75 lakh, and at 12% about ₹1.76 crore. Try a few rates rather than relying on one.
Withdrawal rules at exit
| Corpus at exit (non-government) | What you can do |
|---|---|
| ₹8 lakh or less | Withdraw all of it |
| ₹8 lakh to ₹12 lakh | Up to ₹6 lakh at once; the rest via an annuity or instalments over at least 6 years |
| Above ₹12 lakh | Up to 80% as a lump sum; at least 20% buys an annuity |
These rules came into force in December 2025. Government employees must still put at least 40% of a corpus above ₹12 lakh into an annuity. You can delay your exit and stay invested up to age 85.
Tax on NPS
- Contributions (old regime): within the ₹1.5 lakh Section 80C limit, plus an extra ₹50,000 under 80CCD(1B).
- Employer contributions: deductible under 80CCD(2) up to 14% of basic + DA in the new regime, or 10% in the old regime. This is the only NPS deduction in the new regime.
- Lump sum: tax-free up to 60% of the corpus; any lump sum above that is taxed at your slab.
- Pension: taxed as income in the year you receive it.
