Question 1

What is FIRE (Financial Independence, Retire Early)?

Accepted Answer

FIRE stands for Financial Independence, Retire Early. The idea is to build a corpus large enough that the income it throws off covers your living expenses, so you no longer depend on a salary. People who pursue FIRE usually save and invest a large share of their income (often 40-60%) for a decade or two, then live off their investments. Retiring early is optional. Many just want the freedom to choose whether they work.

Question 2

What are the 25x rule and the 4% rule?

Accepted Answer

The two are the same idea flipped around. The 4% rule says you can withdraw about 4% of your corpus in the first year of retirement (adjusting later for inflation) and be reasonably confident it lasts. Turn that around and your target corpus is your annual expenses divided by 4%, which is 25 times your yearly spending. So if you spend ₹6,00,000 a year, your FIRE number is roughly ₹1,50,00,000.

Question 3

Is the 4% withdrawal rate safe for India?

Accepted Answer

The 4% rule came from US market history, and Indian inflation has usually run higher, which eats into real returns. Because of that, many Indian planners prefer a more cautious 3% to 3.5% withdrawal rate, which pushes the target corpus to roughly 28x to 33x annual expenses. A lower withdrawal rate means a bigger corpus but a much smaller chance of running out during a long retirement.

Question 4

What is the difference between Lean FIRE, Fat FIRE and Coast FIRE?

Accepted Answer

Lean FIRE means reaching independence on a bare-bones budget, so a smaller corpus covers modest expenses. Fat FIRE means a larger corpus that funds a comfortable, spend-freely lifestyle. Coast FIRE is different: you invest enough early on that, even without adding another rupee, compounding alone should grow it into a full retirement corpus by your target age, so you only need to earn enough to cover current expenses in the meantime.

Question 5

How can I reach FIRE faster?

Accepted Answer

Your savings rate is the biggest lever. Saving 50% of your income instead of 20% cuts the timeline dramatically, because you both build the corpus faster and need a smaller one to cover lower expenses. Beyond that, keep costs in check so lifestyle inflation does not track every pay rise, invest through low-cost equity funds for long-term growth, avoid high-interest debt, and revisit your plan every year as income and expenses change.
