NPS Calculator (India)
Estimate what your National Pension System account could grow to by age 60 — and the monthly pension it could buy. Enter your age, monthly contribution and expected return.
The National Pension System (NPS) is a voluntary, market-linked retirement scheme regulated by PFRDA. You contribute regularly until age 60; the money is invested across equity and debt and grows with compounding. At retirement you can withdraw up to 60% as a tax-free lump sum, and the rest (at least 40%) must be used to buy an annuity that pays a monthly pension for life. This calculator estimates all four figures — corpus, lump sum, annuity amount and monthly pension.
How the NPS corpus is calculated
Your monthly contributions are treated as a series invested at the start of each month, growing at your expected annual return compounded monthly until retirement.
where P = monthly contribution, i = return ÷ 12, n = months to retirement
At 60, the annuity portion you choose is set aside to buy a pension; the rest is your lump sum. The monthly pension is the annuity corpus times the annuity rate, divided by 12.
| Monthly (30 yrs, 10%) | Corpus at 60 | Pension |
|---|---|---|
| ₹2,000 | ₹45,58,651 | ₹9,117 |
| ₹5,000 | ₹1,13,96,627 | ₹22,793 |
| ₹10,000 | ₹2,27,93,253 | ₹45,587 |
Worked example
Starting at 30, contributing ₹5,000/month to age 60 at 10%, with 40% used for a 6% annuity:
| Total invested = 5,000 × 360 | ₹18,00,000 |
| Corpus at 60 | ₹1,13,96,627 |
| Lump sum (60%) | ₹68,37,976 |
| Monthly pension (from 40%) | ₹22,793 |
Making the most of NPS
NPS is one of the most tax-efficient retirement tools in India: contributions qualify under Section 80C, with an extra ₹50,000 deduction under 80CCD(1B). The earlier you start, the more compounding works in your favour — note how the corpus scales directly with the monthly amount. Your actual return depends on your asset allocation (equity vs corporate and government bonds) and can be lower or higher than assumed, so treat the projection as a planning guide, not a promise.
