In my previous post, I went in depth about FIRE and how it is calculated. In this post, I\u2019ll cover in detail the implementation of the concept while accounting for inflation! If you haven\u2019t read that post, here\u2019s the link.<\/p>\n\n\n\n
Now although 25x multiplier makes sense if you want to retire today, it won\u2019t suffice if you are planning to retire sometime in the future.<\/p>\n\n\n\n
The 25x multiplier and 4% Rule remains the same for the FIRE Corpus, but will differ for FAT FIRE and LEAN FIRE. Read till the end to know what are FAT and Lean fires.<\/p>\n\n\n\n
Coming to the main point of this article. There\u2019s one culprit who can ruin all your retirement plans, and that culprit is none other than inflation. Accounting for inflation can play a major role in helping you achieve your FIRE Corpus and making it last.<\/p>\n\n\n\n
What\u2019s essentially happening is that over time, the value of money drops. This in finance is commonly referred to as \u2018Time Value of Money\u2019. I\u2019ll keep it simple. The same Dairy Milk I bought for Rs 10 in 2014, offered much more quantity than in 2024.<\/p>\n\n\n\n
Meaning the purchasing power of money has dropped. And this is bound to happen in future as well. This is why it is important to incorporate inflation while calculating FIRE.<\/p>\n\n\n\n
So, how do you do it? It all comes down to the basics again. Have you heard of the compounding interest formula? Yes, math is implemented more than we think it is. (Reminds me of Mitochondria is the powerhouse of the cell!)<\/p>\n\n\n\n
A = P * (1 + R) ^ N<\/strong><\/p>\n\n\n\n This is the compounding interest formula where, P is the principal, R is the rate of interest and N is the number of years.<\/p>\n\n\n\n Ideally, what one needs to do here is inflate your yearly expenses until the year that you\u2019re retiring.<\/p>\n\n\n\n Let\u2019s take an example:<\/p>\n\n\n\n My current yearly expenses are Rs 6 lakh. My current age is 22 and I plan to retire at 50. Based on my lifestyle, I\u2019m assuming an inflation of 7%.<\/p>\n\n\n\n So, this would translate to Rs 6 lakh * (1 + 0.07) ^ (28) = Rs 39,89,303. Now this ~Rs 39 lakh will be multiplied by 25 to arrive at your FIRE Corpus.<\/p>\n\n\n\n Note:<\/strong> Here 0.07 is basically 7%, which is my inflation rate. 28 is the number of years left until my retirement.<\/p>\n\n\n\n This is how you incorporate inflation while calculating your FIRE Number.<\/p>\n\n\n\n Finally, I\u2019m gonna touch upon the other types of FIRE, which are LEAN FIRE, FAT FIRE and COAST FIRE respectively.<\/p>\n\n\n\n Lean FIRE <\/strong>\u2013 This can be viewed as a milestone while achieving FIRE. Instead of multiplying by 25, you\u2019d multiply your expenses by 20. With this corpus you can\u2019t fully retire yet, that\u2019s why I view it as a milestone. But there\u2019s more to do!<\/p>\n\n\n\n Fat FIRE <\/strong>\u2013 Two parameters change here. Firstly, you\u2019ll multiply expenses by 50. Secondly, just withdrawing 2% of your corpus will suffice. PS: Here 2% of the corpus will be equal to your yearly expenses.<\/p>\n\n\n\n Coast FIRE <\/strong>\u2013 This one\u2019s a little different. I\u2019ll explain with an example: Let\u2019s say I want to retire at 50, but I want to stop making investments at 45. I\u2019ll accumulate a corpus such that, once I\u2019m 45, the existing amount will compound to reach FIRE.<\/p>\n\n\n\n FIRE aids people to achieve financial independence and mostly importantly a sense of security about their financial safety.<\/p>\n\n\n\n Disclaimer: The above content is for informational purposes only.
