Mr. Neil Borate, just because someone has a research paper on a subject it doesn't mean that person is correct. Till 1920s-1930s, doctors and physicians promoted cigarette smoking in the US saying it could cure irritated throats. Anyway, let's come to the maths on retirement planning. According to your published article in Mint, a person retiring at 40 years of age with a life expectancy of 90 years requires 50x annual expenses as the retirement corpus. Now, let me share my maths on how the same person can retire with just 60% of the corpus i.e. 30x of annual expenses and would still be left with a considerable corpus after their demise. The following approach has been used in the above calculations: 1. Person will utilize savings bank capital and interest for the first 6 years of retirement and gradually run it down to 0 and let the equity corpus compound 2. From year 7 onwards, the person will do a SWP from equity corpus to cover the annual expenses for entire lifetime Now the next question will be, why have I assumed Index ETF CAGR of 10% for 50 years? This can be argued in two ways, 1. I have also assumed inflation at 7% for the next 50 years which is higher than the inflation rate for the past 20 years 2. The alpha generated by equities over inflation in the past 20 years has been 9% (refer chart below), which is much higher than the 3% alpha assumed in my calculation above I hope this is conservative enough for you and Mr. @ravisaraogi In the past 20 years, Nifty50 has a 9% CAGR alpha over India's consumer price inflation Inflation data is taken from cpi.mospi.gov.in/Inflation_Curr… Taxation The interest will be around 7 lakhs in first couple of years so it's non-taxable. Plus investments can be divided amongst family members for tax efficiency, same rule applies for equity plus it has much lower rate of taxation Here's a month on month chart covering 50 years of retirement for the 40 year old having 20 lakhs annual expenses as per my example. Guess what? He still has 100 crores left to give back to family and society!
