About the NPS Calculator

The National Pension System (NPS) is a government-regulated, market-linked retirement scheme. You contribute regularly until retirement, then must use at least 40% of the corpus to buy an annuity that pays you a monthly pension, while the rest can be withdrawn as a lump sum. This calculator projects your total corpus, lump sum and an indicative monthly pension.

How it works

The accumulation phase uses the standard SIP future value formula on your monthly contribution, compounded monthly at your expected annual return, from your current age to retirement age.
At retirement, the corpus is split: the annuity purchase percentage (minimum 40% under current rules) buys an annuity, and the rest is available as a lump sum.
The estimated monthly pension is a simple approximation: annual annuity payout = annuity corpus × annuity rate, divided by 12.

Assumptions and behaviour

Assumes a constant monthly contribution and a constant expected return throughout the accumulation period — NPS returns are market-linked and vary by the equity/debt/government-securities mix you choose.
The annuity rate you enter is treated as a flat annual payout rate on the annuity corpus — actual annuity products offered by insurers price this differently and rates change over time.
10% is used as a representative long-term return assumption for an equity-heavy NPS allocation; a more conservative or aggressive allocation would change your actual outcome.

Limitations

The monthly pension figure is indicative only — actual annuity payout rates vary significantly by insurer, annuity plan type (with/without return of purchase price, joint life, etc.), and market conditions at the time you retire.
Doesn't model employer NPS contributions under corporate NPS schemes, tax benefits, or partial withdrawals allowed under NPS rules.
Doesn't account for NPS fund management charges which slightly reduce net returns.

Frequently asked questions

Is this NPS calculator free?

Yes — free, no sign-up, no limits, runs in your browser.

What is the minimum annuity purchase percentage in NPS?

Currently at least 40% of your NPS corpus must be used to buy an annuity at retirement; the remaining 60% can be withdrawn as a tax-free lump sum (subject to current rules).

How accurate is the estimated monthly pension?

It's an indicative approximation only. Actual annuity payouts depend on the annuity provider, the specific annuity plan chosen, and prevailing annuity rates at the time of your retirement — these can differ meaningfully from this estimate.

What return should I expect from NPS?

NPS returns depend on your chosen asset allocation across equity, corporate bonds and government securities. An equity-heavy allocation has historically targeted long-term returns around 10%, but this isn't guaranteed and varies with market performance.
