Corpus growth by age

It follows the exit rules PFRDA amended in December 2025: non-government subscribers can take up to 80% as a lump sum and must use at least 20% to buy an annuity.

How NPS corpus and pension are calculated

Corpus = monthly SIP growth to retirement | Pension = Corpus × Annuity % × Annuity rate ÷ 12

Corpus
Value of all contributions at retirement
Lump sum
Up to 80% of the corpus for non-government subscribers
Annuity %
At least 20% (40% for government employees)
Annuity rate
Yearly payout rate offered by insurers, typically 5.5 to 7%

Contributions are assumed monthly with monthly compounding at the expected return. Actual NPS returns depend on your equity, corporate bond and government bond mix.

If your corpus is ₹8 lakh or less, you can withdraw all of it. Generally 60% of the corpus is tax free when withdrawn; check the tax treatment of any amount above that before you exit.

NPS tax benefits

NPS is one of the few investments that still helps under the new tax regime.

  • Employer contributions up to 14% of basic plus DA are deductible in the new regime.
  • Under the old regime, you can claim up to ₹1.5 lakh under 80C plus an extra ₹50,000 under 80CCD(1B).
  • Annuity income is taxed as income in the year you receive it.
  • Partial withdrawals for specific needs are allowed after 3 years.
