What your National Pension System contributions could add up to, how the corpus splits between lump sum and annuity under the December 2025 exit rules, and the pension that buys — in today's rupees too.

Normal exit is at 60; you may stay invested up to 85.
Yours plus your employer's, if any.
An assumption, not a forecast or a promise. NPS returns depend on your equity, corporate-bond and government-bond mix and are not guaranteed.
An assumption. Insurers quote different rates by age and annuity type; the rate at your retirement is unknown today.

How it works

The maths, in plain English.

The corpus. Each monthly contribution is assumed to go in at the start of the month and compound at one-twelfth of the yearly return; the contribution steps up once a year; today's balance grows at the same return. It is the same SIP convention as our retirement calculator.

Exit rules since December 2025. Under the PFRDA (Exits and Withdrawals under the National Pension System) (Amendment) Regulations, 2025, a non-government subscriber making a normal exit — at 60, on superannuation, or after 15 years in NPS — must use at least 20% of the corpus to buy an annuity and may take up to 80% as a lump sum or in phased withdrawals (earlier 40% and 60%). A corpus of ₹8 lakh or less can be withdrawn in full. Between ₹8 lakh and ₹12 lakh there is a further choice: up to ₹6 lakh as a lump sum and the rest through systematic unit redemption over at least six years, with no annuity. Government-sector subscribers still need a 40% annuity above ₹12 lakh. Subscribers may stay invested until 85. The calculator applies the simple version: no compulsory annuity up to ₹8 lakh, then 20% or 40%.

The pension. Annuity purchase amount × annuity rate ÷ 12, for a plain annuity without return of purchase price. Choosing a joint-life or return-of-purchase-price option lowers the rate.

Tax. Income-tax law exempts a lump sum of up to 60% of the corpus at exit (section 10(12A) of the 1961 Act, carried into the 2025 Act). [VERIFY] As of reports to mid-2026 the tax law had not been amended to match the new 80% limit, so the part of the lump sum above 60% is reported as taxable at slab rates; confirm the current position before relying on it. The amount used to buy the annuity is not taxed; the pension is taxed as income each year. Deductions for contributions are outside this calculator.

Assumptions. Constant return, annuity rate and inflation; no partial withdrawals; charges ignored; exits before 60 with under 15 years in NPS follow premature-exit rules (at least 80% to an annuity above a ₹5 lakh corpus) that are not modelled.

Questions

FAQ

How much of my NPS can I withdraw at 60 under the new rules?
Non-government subscribers can take up to 80% of the corpus as a lump sum or in phased withdrawals and must buy an annuity with at least 20%, under PFRDA regulations notified in December 2025. If the corpus is ₹8 lakh or less, all of it can be withdrawn. Government-sector subscribers continue with at least 40% in an annuity.
Is the 80% NPS lump sum tax-free?
Not entirely, on current reports. Income-tax law exempts a lump sum of up to 60% of the corpus. The tax treatment of the additional 20% had not been aligned with the new PFRDA rule as of mid-2026 and is reported as taxable at slab rates; please verify the latest position.
How is the NPS pension calculated?
The share of the corpus used to buy an annuity, multiplied by the annuity rate the insurer offers, divided by twelve. ₹20 lakh at 6% gives ₹10,000 a month. The rate depends on your age, the annuity type and interest rates at the time.
What return should I assume for NPS?
There is no guaranteed figure. Returns depend on how your money is split between equity, corporate bonds and government securities, and on markets. The default is only a placeholder; try a lower number to see a cautious case.
What if my NPS corpus is small?
At normal exit, a corpus of ₹8 lakh or less can be withdrawn fully. Between ₹8 lakh and ₹12 lakh you may take up to ₹6 lakh at once and the balance in phased payouts over at least six years, or buy an annuity.
Do government employees get the 80% lump sum?
No. For government-sector subscribers the December 2025 amendment kept the annuity requirement at 40% of the corpus above ₹12 lakh; the 80% option is for non-government subscribers.
Does this calculator recommend NPS?
No. It is arithmetic on your assumptions and the published exit rules. It does not recommend NPS, any pension fund manager, asset mix or annuity provider.
