NPS Calculator

Retirement

The National Pension System builds a market-linked retirement corpus. At retirement, at least 40% must buy an annuity for a lifelong pension while up to 60% is a tax-free lump sum.

In short: The NPS Calculator is a free online tool that lets you project your National Pension System corpus, lump sum and monthly pension at retirement — instantly, with charts, a worked example and the exact formula.

How the NPS Calculator works

Formula

Corpus = P × [ ((1 + r)ⁿ − 1) / r ] × (1 + r); Pension = (0.4 × Corpus) × a ÷ 12
P
Monthly contribution
r
Monthly rate of return (annual ÷ 12 ÷ 100)
n
Number of monthly contributions until retirement
a
Assumed annual annuity rate (6%)

    Annuity corpus (40%)

    ₹2,27,93,253 × 40%

    = ₹91,17,301

    Monthly pension

    ₹91,17,301 × 6% ÷ 12

    = ₹45,587

How it works

  • Your monthly contributions are invested across equity and debt and compound until retirement.
  • At retirement, at least 40% of the corpus must be used to purchase an annuity that pays a regular pension.
  • The remaining up to 60% can be withdrawn as a tax-free lump sum.

Examples

₹10,000/month from age 30 to 60 at 10% p.a.

Builds a corpus of roughly ₹2.2 crore — about ₹1.3 crore lump sum and a monthly pension near ₹44,000.
