There is no magic number for retirement. A corpus that comfortably supports one retiree may be inadequate for another with higher expenses or a longer retirement. Instead of aiming for an arbitrary figure, financial experts recommend calculating your retirement corpus based on future living costs, inflation, healthcare needs and the number of years your savings will need to last.
For years, Rs 1 crore has been treated as a landmark retirement number in India. Reaching it creates a sense that one’s financial future is secure. The problem with Rs 1 crore is not that it is a small amount. The problem is that the number says nothing about the life it has to fund, says Ajay Kumar Yadav, CFPCM, Group CEO & CIO of Wise Finserv.
Consider someone retiring at 60 and planning for expenses until age 90. If Rs 1 crore earns 7 % annually and the retiree withdraws a fixed amount every month, the corpus can support approximately Rs 66,500 per month for 30 years. However, this calculation does not account for rising expenses.
At 5 % inflation, an expense of Rs 66,500 a month at the beginning of retirement could rise to around Rs 1.08 lakh after 10 years and Rs 1.76 lakh after 20 years. So, while the corpus may last on paper, the retiree’s purchasing power could decline sharply.
If the portfolio earns 7 % and inflation is 5 %, the approximate inflation‑adjusted return is 2 %. On this basis, Rs 1 crore can support purchasing power equivalent to only about Rs 37,000 per month for 30 years.
The difference is significant. A retiree requiring Rs 1 lakh a month could exhaust a Rs 1 crore corpus in approximately 12.5 years if inflation is ignored, but in around 9.1 years when the calculation uses the inflation‑adjusted return.
How much should an investor actually save for retirement? The target should be calculated backwards from the lifestyle an investor wants to maintain.
For instance, a 40‑year‑old spending Rs 1 lakh a month today and planning to retire at 60 would need approximately Rs 3.21 lakh a month at retirement, assuming 6 % annual inflation. The first year’s retirement expenses would therefore be around Rs 38.49 lakh.
Under one calculation, assuming a 7 % return and no post‑retirement inflation adjustment, the required corpus at age 60 is around Rs 4.82 crore. When a 5 % post‑retirement inflation assumption is incorporated, the requirement rises to approximately Rs 8.68 crore.
The 30X rule can be used as an initial adequacy test, but it is not a universal formula. If the first‑year retirement expense is Rs 38.49 lakh, multiplying it by 30 gives a corpus of approximately Rs 11.55 crore. The higher figure provides a larger cushion against market volatility, healthcare expenses, taxes and longevity risk.
Healthcare and longevity are particularly important. Retirement planning should ideally extend to at least age 90 rather than stopping at 75 or 80. Healthcare costs can rise faster than general household expenses, making a separate medical and emergency reserve important.
“The problem is that retirement planning doesn’t work in round numbers. It works in cash flows,” says Yadav. Vedant Gupte, Co‑Founder and CEO of Trackk, adds, “The more useful question today is ‘What kind of life do I want to fund after I stop working, and what corpus will support that?’
For Indian investors, the right retirement number is therefore not Rs 5 crore or Rs 10 crore. It is the inflation‑adjusted corpus required to fund the desired lifestyle, healthcare needs and family responsibilities throughout retirement without running out of money.
