If your goal is to get a fixed pension of ₹20,000 every month after you turn 60, the standard math of funds and annuity required works like this:

  • Necessary pension: ₹20,000 per month (₹2,40,000 annually)

  • Estimated Annuity Rate: 6% per annum

  • Funds required for annuity: $\frac{2,40,000}{0.06} =$ ₹40,00,000 (₹40 lakh)

  • Total NPS Retirement Corpus: Since under NPS rules the total corpus at the age of 60 must be at least 40% share annuity (pension plan) It is mandatory to invest Rs 1 lakh (and 60% can be withdrawn as a tax-free lump sum), so your total corpus for an annuity of Rs 40 lakh would be approx. ₹1 crore (or at least ₹70 lakh to ₹1 crore) Should be.
