How to use this calculator
- Choose non-government (All Citizen or corporate) or government sector.
- Enter your age, when you plan to exit, your monthly contribution and your employer's, and how much both rise each year.
- Pick an expected return and the share you want as a lump sum at exit.
- Enter your salary to see the tax you save this year in each regime.
How it is calculated
Contributions are invested at the start of each month and grow at the expected return ÷ 12 each month, rising once a year by the step-up you choose. At exit:
Monthly pension = Corpus × (100% − lump sum %) × annuity rate ÷ 12
Example:₹5,000 a month from age 30 to 60, rising 5% a year, at 10%: corpus ₹1,79,65,105. Taking 60% as a tax-free lump sum gives ₹1,07,79,063; the remaining ₹71,86,042at 6% pays about ₹35,930 a month before tax.
Rules and sources
- Exit rules: PFRDA (Exits and Withdrawals under the National Pension System) Regulations, 2015, as amended up to 20 July 2026 — regulation 4(1) for non-government subscribers, regulation 3 for government. The December 2025 amendment raised the non-government lump sum from 60% to 80%.
- Tax: Income-tax Act, 2025 (as amended by the Finance Act, 2026) — exempt-income schedule, serial 6 (lump sum up to 60%), sections 123 and 124 (deductions). Annuity income is taxed at your slab rate.
- Returns and annuity rates are assumptions; neither is guaranteed. Government employees are assumed to exit at retirement.
Frequently asked questions
How much of my NPS can I withdraw at 60?
Since 16 December 2025, non-government subscribers (All Citizen and corporate) can take up to 80% as a lump sum or as regular withdrawals; at least 20% must buy an annuity. Government employees must still put at least 40% into an annuity. If the corpus is ₹8 lakh or less, all of it can be withdrawn.
Is the NPS lump sum tax-free?
Only up to 60% of the corpus. The Income-tax Act, 2025 exempts an NPS payment on closure up to 60% of the amount payable, so a lump sum above that is added to your income in that year. In the example, taking the full 80% means ₹35,93,021 is taxable.
What tax do I save by investing in NPS?
In the old regime your own contribution counts towards the ₹1,50,000 section 123 limit and then up to ₹50,000 more under section 124(3). The employer's contribution is deductible up to 10% of basic + DA in the old regime (14% for government) and 14% in the new. With the example salary and ₹5,000 a month of your own, you would save ₹15,600 this year in the old regime and ₹0 in the new.
Can I leave NPS before 60?
Non-government subscribers can make a normal exit after 15 years in NPS even before 60. Leaving earlier than both is a premature exit: at least 80% must buy an annuity, unless the corpus is ₹5 lakh or less.
What if NPS returns are lower than I expect?
The corpus shrinks a lot over long periods. In the example, 10% a year builds ₹1.8 crore by 60; 8% builds ₹1.26 crore.
