How this works

The NPS grows your monthly contributions into a retirement corpus, then splits it into a lump sum and a lifelong pension.

1

You contribute monthly

Every month you invest a fixed amount until retirement. We compound it at your expected return, treating each contribution as made at the start of the month (annuity-due).

2

It grows into a corpus

Over the years the returns compound on top of your contributions. The corpus is your total invested amount plus all the market-linked growth on it.

3

Corpus → pension + lump sum

At 60 you use at least 40% to buy an annuity (your monthly pension) and withdraw the rest — up to 60% — as a tax-free lump sum.

The formula & assumptions we use

Accumulation (monthly SIP)

With monthly contribution M, monthly rate i = return ÷ 12 ÷ 100 and n = (retirement − current age) × 12 months, the corpus is computed as an annuity-due:

Corpus = M × ((1 + i)ⁿ − 1) ÷ i × (1 + i)

Total invested = M × n, and the wealth gain is the corpus minus what you put in. If the return is 0%, the corpus simply equals your total contributions.

At retirement

The corpus is split using your annuity percentage (minimum 40%):

Annuity corpus = Corpus × annuity%
Lump sum = Corpus × (1 − annuity%)
Monthly pension = Annuity corpus × annuity-return% ÷ 12

Up to 60% of the corpus is tax-free at withdrawal. The annuity provides your monthly pension for life.

Tax note: your own NPS contributions get an extra ₹50,000 deduction under Section 80CCD(1B), over and above the ₹1.5 lakh 80C limit (old regime). At least 40% of the corpus must be annuitised at exit. Returns are market-linked and not guaranteed — this is an estimate to help you plan, not financial advice. Confirm details with your NPS provider or an advisor.

Frequently Asked Questions

What is the National Pension System (NPS)? ▼
The NPS is a voluntary, market-linked retirement savings scheme regulated by the PFRDA. You contribute regularly during your working years, the money is invested across equity, corporate bonds and government securities, and it grows into a retirement corpus. At retirement you must use at least 40% of that corpus to buy an annuity (a lifelong pension) and can withdraw the rest as a lump sum.
How much of my NPS corpus can I withdraw as a lump sum? ▼
At age 60 you can withdraw up to 60% of your accumulated corpus as a lump sum, and this withdrawal is fully tax-free. The remaining minimum 40% must be used to purchase an annuity that pays you a monthly pension for life. You can choose to annuitise more than 40% if you want a larger pension.
What tax benefits does NPS offer? ▼
Your own NPS contributions qualify for deduction under Section 80CCD(1) within the overall ₹1.5 lakh 80C limit, plus an additional ₹50,000 deduction under Section 80CCD(1B) that is over and above 80C. If your employer contributes, that is separately deductible under Section 80CCD(2). The 80CCD(1B) benefit is only available under the old tax regime.
How is the monthly pension calculated? ▼
The annuity portion of your corpus (at least 40%) is used to buy an annuity from a life-insurance company. Your pension depends on the annuity rate offered at that time — this calculator estimates it as the annuity corpus multiplied by the expected annuity return, divided by 12. Actual annuity rates vary by provider, annuity type (with or without return of purchase price) and prevailing interest rates.
Are the returns shown here guaranteed? ▼
No. NPS returns are market-linked and not guaranteed. The figures here are projections based on the expected return rate you enter, assuming a fixed monthly contribution and steady compounding. Real returns depend on your asset allocation (equity vs debt), fund performance and market conditions, so treat these numbers as an estimate for planning, not a promise.
Can I contribute to NPS beyond age 60? ▼
Yes. You can continue contributing until age 75, and you can also defer the lump-sum withdrawal and annuity purchase. This calculator models the common case of accumulating up to your chosen retirement age (default 60) and then annuitising, but the NPS itself allows more flexibility on exit timing.
