NPS Calculator
National Pension System calculator for India. Estimate your retirement corpus from your current balance, monthly contributions (with optional annual step-up), and expected returns—then see an illustrative split between annuity purchase, lumpsum, and monthly pension based on your annuity assumptions.
NPS is open to Indian citizens in eligible age bands; adjust for your situation.
Corpus is projected to this age. Many subscribers plan around 60; deferral can be modeled with a higher age if you intend to stay invested longer.
Current value of your Tier I account, if any. Enter 0 if you are only planning future contributions.
Combined employee, employer, and voluntary Tier I contributions per month. In the last year before retirement, monthly amount reaches about ₹1,58,631 with your step-up settings.
How much your monthly contribution increases each year (e.g. salary growth). Use 0 for a flat contribution.
Illustrative blended return; actual NPS returns depend on scheme choice and markets and are not guaranteed.
Share of corpus used to buy annuity versus lumpsum. Regulatory minimums vary; 40% is a common planning reference for normal retirement but is not universal.
Used only to translate annuity corpus into an illustrative monthly pension; real quotes depend on annuity providers and products at exit.

National Pension System (NPS) calculator for retirement planning
The National Pension System is a long-term, market-linked retirement savings framework widely used by private-sector employees, self-employed individuals, and others who want a structured path to retirement income. Unlike a fixed-guarantee deposit, NPS builds wealth through contributions and investment performance in regulated pension schemes, with rules for how much can be withdrawn as lumpsum and how much may need to be annuitized at exit, depending on corpus size and exit type.
This NPS calculator helps you translate today's choices—how much you invest each month, whether you step up with salary growth, and what return you assume—into an illustrative retirement corpus. You can also model how splitting that corpus between annuity purchase and lumpsum affects an estimated monthly pension, using an annuity rate you choose for planning only.
Why use an NPS calculator?
- Scenario planning: Compare flat versus step-up contributions and different retirement ages without manual spreadsheet work.
- Corpus clarity: See how an existing Tier I balance compounds alongside future monthly investments.
- Annuity versus lumpsum: Understand how annuity ratio changes illustrative pension and lumpsum, before you lock in real products at exit.
- Expectation setting: Stress-test optimistic and conservative return assumptions—markets vary, and no calculator can promise outcomes.
How the math works (summary)
Your existing corpus is projected forward to the retirement age using monthly compounding at your assumed annual return. Each new monthly contribution is modeled like a step-up SIP: the amount in year t is the starting monthly amount times (1 + g)t−1, where g is your annual step-up rate. The future value of each monthly payment is aggregated the same way as in a standard SIP future-value calculation. At the end, the tool applies your annuity ratio to split the corpus, then estimates monthly pension as annuity corpus × annuity rate ÷ 12.

Frequently asked questions
What is the National Pension System (NPS)?
NPS is a voluntary, defined-contribution pension system regulated in India for long-term retirement savings. Subscribers choose asset allocation across permitted schemes; the accumulated corpus is used at exit to provide a lumpsum component and a pension through an annuity, subject to rules applicable at that time.
How does this NPS calculator estimate my retirement corpus?
The calculator compounds your existing Tier 1 balance and projects future monthly investments month by month. Each year your monthly contribution can grow by the annual step-up percentage you enter. Investment growth uses the expected annual return you specify, converted to a monthly rate. The result is an illustrative corpus at your chosen retirement age, not a guarantee.
What is annuity ratio in NPS planning?
Annuity ratio is the portion of your projected corpus you assume will be used to buy a life annuity at exit. The remainder is treated as lumpsum in this calculator. Regulatory minimums for annuity purchase depend on corpus size and exit type; many subscribers use at least 40% for annuity on normal retirement, but you should confirm current rules with official sources or a qualified adviser.
How is estimated monthly pension calculated here?
Monthly pension is a simplified illustration: the annuity portion of your corpus is multiplied by your expected annuity rate per year, then divided by twelve. Real annuity quotes depend on insurer, age, product, and regulations at exit.
Are NPS returns guaranteed?
No. NPS is market-linked except where a scheme explicitly states otherwise. Past scheme performance does not predict future returns. The expected return in this tool is only your assumption for planning.
What tax benefits are associated with NPS?
Tax treatment depends on your status (subscriber type), choice of old or new tax regime, and current law. Employees may get deductions under sections such as 80CCD within overall limits. Withdrawal taxation has specific rules for lumpsum and annuity. Consult the Income Tax Act or a tax professional for your situation.
What is the difference between NPS Tier I and Tier II?
Tier I is the primary pension account with withdrawal restrictions until exit as per rules. Tier II is a voluntary savings account with more flexible withdrawals; tax benefits differ from Tier I. This calculator focuses on long-term accumulation similar to Tier I planning.
Can I withdraw from NPS before retirement age?
Partial withdrawals under Tier I are allowed in defined circumstances after a minimum membership period, subject to caps and conditions. Premature complete exit has different corpus and annuity requirements than normal retirement. This calculator does not model partial withdrawals.
Is this NPS calculator from a government or pension regulator?
No. ZeroKhata provides this calculator for general education and planning. It is not affiliated with NPS Trust, PFRDA, or any pension fund. Do not treat outputs as advice; verify rules, charges, and product terms before investing.
