For decades, the narrative around retirement has been the same: work until you are 65, rely on a company pension, and hopefully have enough saved to survive.
Recently, a massive counter-movement known as F.I.R.E. (Financial Independence, Retire Early) has flipped that narrative on its head. The FIRE movement proposes that retirement is not an age—it's a number. Once your investment portfolio reaches a specific threshold, you can safely withdraw enough money to live on forever without ever having to work again.
The 4% Rule
The entire FIRE movement is based on the Trinity Study, which found that if you invest your money in a diversified portfolio of stocks and bonds, you can safely withdraw 4% of that portfolio every year, adjusted for inflation, for 30+ years without ever running out of money.
To calculate your FIRE number, you simply take your expected annual expenses and multiply them by 25 (since 100 / 4 = 25). Use the calculator below to find yours.
Lean F.I.R.E.
Aggressive target. Assumes a 5% withdrawal rate. Requires a very frugal lifestyle and part-time side hustles.
Fat F.I.R.E.
Safe, luxurious target. Assumes a conservative 3% withdrawal rate. Allows for lots of travel and a lavish lifestyle.
How to Reach Your Target Faster
Looking at a multi-million rupee target can be incredibly daunting. But remember, you do not have to save that entire amount from your paycheck. Compound interest will do the heavy lifting in the later years. Here are the two main levers you control to accelerate the process:
- Increase Your Savings Rate: If you save 10% of your income, it will take you roughly 50 years to retire. If you save 50% of your income, you can retire in exactly 17 years. The gap between your income and your expenses is the only metric that matters.
- Lower Your Expected Expenses: Because of the multiplier effect (25x), every ₹1,000 you permanently cut from your annual budget lowers your required FIRE number by ₹25,000. Moving to a lower-cost-of-living area or paying off your mortgage completely slashes the size of the portfolio you need to build.
