Model how a current NPS corpus and continuing monthly contributions could grow by retirement. Then split the projected corpus between a selected lump-sum share and annuity allocation to estimate an illustrative pension.

NPS returns and annuity rates are not guaranteed. The selected annuity share is a planning input, not a statement of the exit rule for every subscriber or corpus.

What this NPS calculator shows

  • Estimated retirement corpus.
  • Selected lump-sum amount.
  • Selected annuity purchase amount.
  • Illustrative monthly annuity payout.

NPS projection method

The current corpus compounds monthly at the expected annual return. Monthly contributions are treated as end-of-month investments and grow as an ordinary annuity:

NPS projection formulas
  • Corpus = current corpus growth + future value of monthly contributions
  • Monthly pension = annuity corpus x assumed annuity rate / 12

For example, an annuity corpus of Rs. 40 lakh at an illustrative 6% annual payout produces Rs. 20,000 a month before tax. This is arithmetic, not an annuity quotation.

Market and exit assumptions

NPS returns are market-linked and depend on asset allocation, fund performance, charges, and contribution timing. Run lower and higher return scenarios. A smooth constant return cannot show volatility or sequence risk.

The annuity share is an input because exit requirements can differ by subscriber category, exit reason, age, corpus, and rules in force at exit. The calculator does not assert that 40% is mandatory in every case. Verify current PFRDA and CRA rules for your account before withdrawal.

Use the official PFRDA NPS overview and NPS Trust FAQs to verify the rules for your subscriber category and exit type.

Actual annuity income depends on the provider, purchase price, age, joint-life or return-of-purchase-price option, prevailing rates, and tax treatment. Obtain live quotes near retirement.

Common questions

Is the estimated monthly pension guaranteed?

No. It multiplies the selected annuity corpus by an assumed payout rate. Only an issued annuity contract can state the actual payout.

Does the calculator include tax benefits?

No. It does not calculate Sections 80CCD(1), 80CCD(1B), or 80CCD(2), regime eligibility, withdrawal tax, or annuity-income tax.

Should employer contributions be included?

Include them in the monthly contribution only if they are expected to continue. Do not double-count an amount already reflected in the current corpus.
