Monthly pension
₹22,793
Estimates are indicative and assume a constant annual return compounded monthly with the corpus split into a lump sum and an annuity at retirement. NPS returns are market-linked and not guaranteed; the actual annuity rate, pension and tax depend on your insurer, asset mix and tax regime. This is not investment or tax advice. Employer contributions are not included.
Estimated monthly pension by start age
Monthly pension at retirement (age 60), assuming a 10% return, 40% of the corpus annuitised at a 6% annuity rate, flat contributions, before inflation. Your own numbers may differ — use the calculator above to model them.
| Monthly contribution | Start age 25 | Start age 30 | Start age 35 |
|---|---|---|---|
| ₹5K/mo | ₹38.3K/mo | ₹22.8K/mo | ₹13.4K/mo |
| ₹10K/mo | ₹76.6K/mo | ₹45.6K/mo | ₹26.8K/mo |
| ₹20K/mo | ₹1.53 L/mo | ₹91.2K/mo | ₹53.5K/mo |
Step-up vs. flat contribution
Both start at ₹10,000/month from age 30 to 60 at 10%. The step-up version raises the contribution 5% every year — roughly a modest salary hike.
Flat corpus
₹2.28 Cr
5% step-up corpus
₹3.59 Cr
Extra corpus
+58%
The step-up plan also lifts the estimated monthly pension from ₹45.6K/mo to ₹71.9K/mo.

NPS calculator guide
How the National Pension Scheme turns regular contributions into a retirement corpus, how that corpus splits into a lump sum and a lifelong pension, and how to read every number this calculator gives you.
What is the National Pension Scheme?
The National Pension Scheme (NPS) is a voluntary, market-linked retirement product regulated by the PFRDA. You contribute to a Tier I account during your working years; the money is invested across equity, corporate bonds and government securities and compounds until you exit (usually at 60). At exit, a minimum share of the corpus must be used to buy an annuity — a lifelong monthly pension — and the rest can be withdrawn as a tax-free lump sum.
From corpus to monthly pension
Two numbers decide your pension. First, your annuity share — the percentage of the corpus you annuitise (the rest is your lump sum). Second, the annuity rate — the annual rate the insurer pays on that annuity corpus. Your monthly pension is simply the annuity corpus × annuity rate ÷ 12. A larger annuity share means a bigger pension but a smaller lump sum, and vice versa.
The levers that change your outcome
Start age & tenure
The earlier you start, the longer each contribution compounds. Starting at 30 instead of 40 can roughly double the final corpus for the same monthly amount.
Step-up
Raising your contribution each year with your salary invests more money earlier, so it compounds longer. Toggle it on in Advanced options to see the lift.
Annuity share
Government subscribers annuitise at least 40% (lump sum capped at 60%). After the December 2025 PFRDA reform, private subscribers can take up to 80% as lump sum.
Inflation
A pension that looks large in 30 years buys far less in today's terms. The inflation toggle restates both your corpus and pension in present-day rupees.
Tax benefits under Section 80CCD
Under the old tax regime, NPS contributions are deductible under Section 80CCD(1) within the ₹1.5 lakh Section 80C ceiling, plus an exclusive extra ₹50,000 under Section 80CCD(1B) — a combined deduction of up to ₹2 lakh a year. The tax-savings panel quantifies what that means at the 20% and 30% slabs. The new tax regime generally does not allow these deductions, so check which regime applies to you.
Working backwards from a target pension
Switch to the Goal tab when you already know the monthly pension you want — say ₹50,000 a month — and want to find the monthly contribution that gets you there. The calculator reverse-solves for the required contribution given your annuity share, annuity rate and tenure.
