About this calculator

The National Pension System (NPS) is a voluntary, long-term retirement savings scheme designed to enable systematic savings and secure your financial future. This calculator projects your retirement corpus, immediate lump-sum tax-free payout, and estimated monthly pension based on contribution levels and market returns.

How to use this calculator

  1. Enter your monthly contribution and age details

    Input your regular monthly retirement contribution. Provide your current age and planned retirement age (typically 60) to determine your investment duration.

  2. Set expected returns and annuity rates

    Input your expected annual returns based on your choice of NPS asset allocation (Equity, Corporate Debt, Government Bonds). Enter the expected annuity rate for your pension phase.

  3. Select your annuity allocation percentage

    Under NPS guidelines, you must convert a minimum of 40% (and up to 100%) of your retirement wealth into an annuity. The remaining portion is withdrawn tax-free.

  4. Examine retirement corpus and pension estimates

    Instantly view your estimated total retirement accumulation, the cash lump-sum payout available on day one, and your projected monthly pension.

Formula

Retirement Corpus = P × [ ((1 + i)ⁿ − 1) ÷ i ] × (1 + i)
  • P is the regular monthly contribution.
  • i is the expected monthly rate of return (annual return divided by 12, then by 100).
  • n is the total investment months (retirement age minus current age multiplied by 12).
  • Annuity Corpus = Total Corpus × Annuity Allocation % (Minimum 40%).
  • Lump Sum Amount = Total Corpus − Annuity Corpus (Maximum 60%).
  • Monthly Pension = Annuity Corpus × Assumed Annuity Rate % ÷ 12.

Worked example

Inputs

  • Monthly contribution (P): ₹10,000
  • Expected return: 10% per year
  • Age details: 30 years old today, retiring at 60 (30 years tenure / 360 months)
  • Annuity allocation: 40% (Minimum)
  • Annuity interest rate: 6% per year

Calculation

i = 10% / 12 / 100 = 0.0083333 n = 30 * 12 = 360 Total Corpus = 10000 * [ ((1.0083333)³⁶⁰ − 1) / 0.0083333 ] * 1.0083333 = ₹2,27,93,253 Annuity Corpus (40%) = 2,27,93,253 * 40% = ₹91,17,301 Lump Sum Payout (60%) = 2,27,93,253 - 9,117,301 = ₹1,36,75,952 Projected Monthly Pension: Pension = (91,17,301 * 6%) / 12 = ₹45,587

With a ₹10,000 monthly contribution from age 30 to 60, your projected total retirement corpus is ₹2.28 Crore. You withdraw ₹1.37 Crore in tax-free cash on day one and earn an estimated ₹45,587 monthly pension.

What the result means

  • Total Invested is the simple sum of your monthly contributions over your working life (e.g. ₹36 Lakhs in the example).
  • Accumulated Interest is the market-linked compounded growth earned on your monthly investments (e.g. ₹1.92 Crore).
  • Lump Sum Amount is the tax-free cash available for you to withdraw immediately upon retirement at age 60.
  • Monthly Pension is the estimated regular monthly income paid to you for life by your chosen Annuity Service Provider (ASP).

Related calculations

  • Vary your asset allocation returns between 8%, 10%, and 12% to see how equity market performance shifts your final retirement pension.
  • Increase your retirement age from 60 to 65 to see how 5 extra years of compounding can dramatically expand your pension corpus.
  • Test raising your annuity allocation percentage to 100% to evaluate a pure pension payout with zero cash withdrawal.

Frequently asked questions

What is the National Pension System (NPS)?

The National Pension System (NPS) is a voluntary, contribution-based pension scheme launched by the Government of India. It is regulated by the Pension Fund Regulatory and Development Authority (PFRDA). NPS allows you to invest systematically during your working life, accumulating a retirement corpus that is partially withdrawn as tax-free cash and partially used to purchase a regular lifetime pension.

What is the minimum annuity requirement under NPS rules?

According to PFRDA guidelines, you must allocate a minimum of 40% of your accumulated NPS retirement corpus to purchase a life annuity (which provides your monthly pension). The remaining 60% can be withdrawn as a tax-free lump sum. If your total corpus at age 60 is ₹5 Lakhs or less, you have the option to withdraw 100% as cash without any annuity purchase.

Is NPS interest or corpus taxable?

NPS enjoys substantial tax benefits. Contributions are deductible up to ₹1.5 Lakhs under Section 80C plus an additional exclusive deduction of ₹50,000 under Section 80CCD(1B). Additionally, the 60% lump-sum withdrawal at retirement is completely tax-free. However, the monthly pension payouts you receive from the annuity are taxable as regular salary income based on your tax slabs.

What are the asset classes available in NPS?

NPS offers four asset classes: Asset Class E (Equity), Asset Class C (Corporate Debt), Asset Class G (Government Securities), and Asset Class A (Alternative Assets). You can choose your asset mix manually using "Active Choice" (subject to a maximum 75% equity cap up to age 50) or opt for "Auto Choice", which adjusts your risk exposure dynamically based on your age.

How is the NPS monthly pension calculated?

Your monthly pension is determined by the size of your Annuity Corpus (minimum 40% of your final wealth) and the prevailing annuity interest rate offered by the insurer (such as LIC, SBI Life, or HDFC Pension). For instance, an annuity corpus of ₹50 Lakhs at an expected annuity rate of 6% yields: (₹50 Lakhs × 6%) ÷ 12 months = ₹25,000 monthly pension.

Can I withdraw my NPS corpus before retirement?

NPS is primarily a lock-in scheme focused on long-term retirement security. However, you can make partial tax-free withdrawals of up to 25% of your own contributions after 3 years of membership under specific conditions, such as child education, medical treatment, or home purchase. Complete premature exit is allowed but requires converting 80% of the entire corpus into an annuity.
