Why this NPS pension calculator is more accurate
Most NPS calculators still assume the old 60:40 split and stop at a nominal pension figure. This one follows the current rules and shows what the money will really be worth.
2026 exit rules built in
The 80% lump sum limit, the 20% minimum annuity and the ₹8 lakh and ₹12 lakh corpus slabs are applied automatically.
Pension in today’s money
A ₹1 lakh pension in 30 years buys far less than it does now. We adjust for inflation so you can judge if it is enough.
Tax-free vs taxable lump sum
Only 60% of the corpus is tax-free. If you take the full 80%, we show the part that will be taxed at your slab.
Salary growth and employer share
Raise contributions every year and add your employer’s NPS contribution for a projection that matches a real career.

How to use the NPS calculator
Five steps give you your corpus, lump sum and pension.
Enter your age and retirement age
Normal exit is at 60, but you can stay invested longer. The gap is how many years your money compounds.
Add your monthly contribution
Type it or use the slider, then set a yearly increase if your contribution will grow with your salary.
Pick an expected return
Choose conservative, balanced or aggressive, or enter your own rate based on your fund mix.
Fine-tune the advanced settings
Add an employer contribution, choose your subscriber type, annuity share, annuity rate and tax regime.
Read your retirement picture
Check the corpus, the lump sum split, your monthly pension in today’s money and your tax saving, then copy the summary.
The maths
How NPS pension and corpus are calculated
Your contributions are invested in pension funds every month and grow at the return you assume. The calculator compounds each contribution monthly until your retirement age, raising the amount once a year if you set a yearly increase.
At exit, the corpus is split into a lump sum and an annuity. The annuity is a policy you buy from an insurer that pays you a fixed pension for life. The monthly pension is the annuity amount multiplied by the annuity rate and divided by 12.
Why the annuity rate matters
Annuity rates depend on your age at purchase and the option you pick, such as life-only or return of purchase price. A 1% difference in the rate changes your pension by roughly a sixth, so check current quotes before you retire.
Why we show today’s money
At 6% inflation, prices double roughly every 12 years. The pension in today’s money divides the future pension by inflation for every year until you retire, so you can compare it with your current expenses.

New NPS withdrawal rules explained
PFRDA revised the exit rules in December 2025. Here is how they work for Tier I accounts.
- Normal exit at 60
- Private and self-employed subscribers can take up to 80% as a lump sum and must buy an annuity with at least 20%. Government employees keep the 60% and 40% split.
- Corpus of ₹8 lakh or less
- You can withdraw the entire corpus as a lump sum, with no annuity purchase required.
- Corpus of ₹8 to 12 lakh
- You can take up to ₹6 lakh as a lump sum. The rest goes to an annuity or is paid out through phased withdrawals.
- Exit before 60
- At least 80% must buy an annuity and up to 20% can be withdrawn. If the corpus is ₹5 lakh or less, all of it can be withdrawn.
- Partial withdrawals
- After three years, you can withdraw up to 25% of your own contributions for needs such as education, marriage, a first home or treatment, a limited number of times.
- Stay invested up to 85
- You can defer your exit and keep your money invested until age 85, and withdraw the lump sum in instalments.
Check the latest regulations on the PFRDA website before you plan your exit.
Why invest
Tax benefits and advantages of NPS
NPS is a government-regulated retirement scheme open to Indian citizens aged 18 to 70.
Extra ₹50,000 deduction
Under the old regime, your own contribution qualifies for ₹50,000 under Section 80CCD(1B), over and above the ₹1.5 lakh Section 80C limit. Work out your tax with the income tax calculator.
Employer contribution deduction
Employer contributions are deductible under Section 80CCD(2) in both regimes, up to 14% of basic pay plus DA in the new regime and 10% in the old regime for private employees.
60% tax-free at exit
Up to 60% of the corpus is tax-free when you retire. Only the extra lump sum above 60% and the annuity income are taxed.
Very low costs
NPS fund management charges are among the lowest of any investment product in India, so more of your return stays with you.
Your choice of funds
Pick Auto Choice to lower equity as you age, or Active Choice to set your own mix across equity, corporate bonds and government bonds.
Answers
NPS calculator FAQs
What does an NPS calculator do?
An NPS calculator projects how your monthly contributions grow until retirement, then splits the final corpus into the lump sum you can withdraw and the annuity that pays your pension. This one also shows the pension in today’s money and the tax-free part of the lump sum.
How much pension will I get if I invest ₹5,000 a month in NPS?
Investing ₹5,000 a month from age 30, raised 5% every year, at an assumed 10% return builds a corpus of about ₹1,65,93,814 by 60. Putting the minimum 20% into an annuity at 6% gives a pension of about ₹16,594 a month, and you can withdraw up to ₹1,32,75,051 as a lump sum.
What are the new NPS withdrawal rules?
Since the December 2025 PFRDA changes, private and self-employed subscribers can withdraw up to 80% of the corpus at 60 and must use at least 20% for an annuity. If the corpus is ₹8 lakh or less, all of it can be withdrawn. Between ₹8 lakh and ₹12 lakh, up to ₹6 lakh can be taken as a lump sum. Government employees continue with a 60% lump sum and 40% annuity.
Is the NPS lump sum tax-free?
Up to 60% of the total corpus is tax-free when you exit at retirement. If you withdraw more under the 80% rule, the extra portion is taxed at your slab rate. The pension from the annuity is also taxed as income every year.
How much tax can I save with NPS?
Under the old regime, your own contributions qualify for up to ₹1.5 lakh within Section 80C and an extra ₹50,000 under Section 80CCD(1B). Employer contributions are deductible under Section 80CCD(2) in both regimes, up to 14% of basic pay plus DA in the new regime and 10% in the old regime for private employees.
What return should I assume in an NPS calculator?
NPS returns depend on your fund mix. Equity funds have historically returned roughly 10 to 12% a year over long periods, and government bond funds about 8 to 9%. Assume 8% if you are conservative, 10% for a balanced mix and 12% only if you hold high equity for most of your career.
Can I withdraw from NPS before 60?
Yes. After three years you can make partial withdrawals of up to 25% of your own contributions for needs such as education, marriage, a first home or medical treatment. If you leave NPS before 60, at least 80% of the corpus must buy an annuity, unless the corpus is ₹5 lakh or less, when all of it can be withdrawn.
What is the minimum contribution to NPS?
A Tier I account needs at least ₹1,000 a year, with a minimum of ₹500 per contribution. There is no upper limit, although tax deductions are capped.
What is the difference between NPS Tier I and Tier II?
Tier I is the main pension account, with tax benefits and withdrawal limits until retirement. Tier II is an optional savings account you can withdraw from at any time, but it gives no tax deduction for most subscribers.
Know your pension before you retire
Use the NPS calculator to set a contribution that gives you the pension you want in today’s money, and revisit it each year as your salary grows. Small increases now make a large difference by 60.
