How Inflation affects Retirement Corpus?

You might ask what about inflation? That’s a very important aspect that can jeopardize any financial plan. The 4% rule is built in such a way that you can withdraw enough money to maintain the same lifestyle despite inflation, say 3 to 4%. So, you can withdraw in the second year an amount of (11 lacs + 33K for inflation) and third-year withdrawal will be 11.67 lacs and so on.


  • This is just a thumb rule — consult your financial advisor for detailed advice.
  • This corpus is only to maintain regular expenses. Any extraordinary major expenses like college admission, children’s weddings are not covered. One should create separate funds for them.
  • Financial discipline is paramount — DO NOT withdraw big chunks from the corpus. This will affect future earnings and might lead to financial distress.
  • Not applicable in hyperinflationary economies like Venezuela.
  • Pension is not considered
