NPS Calculator
Project your National Pension System (NPS) corpus at 60, the lump sum and the monthly annuity pension.
About the NPS Calculator
NPS invests your contributions in equity, corporate and government bonds. At 60, part of the corpus must buy an annuity (a lifelong pension). Under PFRDA's December 2025 exit rules, non-government subscribers with a corpus above ₹12 lakh must annuitise at least 20% and can take up to 80% as a lump sum; government subscribers keep the 40% minimum annuity. Smaller corpuses can be withdrawn fully.
Tax on withdrawals depends on current income-tax rules; check them before you exit.
The formula
Corpus = monthly contributions grown at the expected return; pension = annuity amount × annuity rate ÷ 12
Worked example
Example: Corpus at 60 = ₹1,09,37,983
- Inputs: Current age: 33 years; Monthly contribution: 5,500 ₹; Expected return: 11%; Subscriber type: All citizens / corporate; Share used to buy an annuity: 22%; Annuity rate: 7.2%.
- Formula: Corpus = monthly contributions grown at the expected return; pension = annuity amount × annuity rate ÷ 12
- Result: Corpus at 60 = ₹1,09,37,983
- Total contributed: ₹17,82,000
- Monthly pension: ₹14,438
Things to keep in mind
- Exit rules were changed in December 2025; check the latest PFRDA circular before deciding.
