FIRE Calculator (India)

What your FIRE number actually is

FIRE stands for Financial Independence, Retire Early. Your FIRE number is the corpus at which your investments can cover your living costs indefinitely, so continuing to work becomes a choice rather than a requirement. It is a net worth target, nothing more exotic than that.

The appeal is that it converts a vague ambition into one figure you can track against. The risk is that the figure most people quote is borrowed from American research and does not survive contact with Indian inflation.

How the number is worked out

The standard method starts with the 4% safe withdrawal rule, drawn from the Trinity Study on US market history. Withdraw 4% of your corpus in year one, adjust it for inflation each year after, and the portfolio should survive a 30-year retirement.

FIRE Number = Annual Expenses × 25

The 25 is simply the inverse of 4%. Spend ₹12 lakh a year and you need roughly ₹3 crore.

Why 25x is optimistic for India

Three things make the American number a poor fit here, and this is the part most FIRE content skips.

• Inflation runs higher. Indian CPI has averaged meaningfully above US inflation for decades. A withdrawal rule calibrated to 2 to 3% inflation behaves differently at 5 to 6%.
• Healthcare has no floor. There is no public safety net comparable to Medicare, and medical inflation in India runs far ahead of general inflation, often quoted in the low double digits. Your largest expense may arrive in the decade you have the least ability to earn.
• Early retirement means a longer runway. The 4% rule was tested against 30 years. Retire at 45 and you may need the corpus to last 45.

Many Indian planners work with 30 to 33 times annual expenses instead, which is a withdrawal rate closer to 3%. On ₹12 lakh of spending, that moves the target from ₹3 crore to ₹3.6 to ₹4 crore. A 33% difference in the goalpost is worth knowing before you plan a decade around it.

A worked example

You are 34, spend ₹15 lakh a year, and have a net worth of ₹1.2 crore. At 25x your target is ₹3.75 crore. At the more conservative 30x it is ₹4.5 crore. Saving ₹18 lakh a year at a 10% real-ish return, you reach the first figure in roughly 9 years and the second in about 11. The gap between the two assumptions is two more years of working, which is a very different thing from a rounding error.

The variants people mean

• Lean FIRE. The same maths on a deliberately smaller expense base.
• Fat FIRE. The same maths with a comfortable lifestyle built in.
• Coast FIRE. You stop adding to the corpus and let compounding carry it to your target by your normal retirement age. You still work, but you can stop optimising for savings rate.
• Barista FIRE. Partial income covers part of your costs, so the corpus does less work.

What this calculation does not capture

• Your savings rate matters far more than your return assumption. Someone saving 50% of income reaches independence in roughly half the time of someone saving 20%, regardless of what the market does.
• Expenses are not static. A child, a dependent parent or a move to a metro can reset your base by a third.
• Sequence-of-returns risk is real. A bad market in your first two years of withdrawal damages the corpus far more than the same fall a decade later.
• Illiquid net worth does not fund withdrawals. The flat you live in cannot pay your grocery bill.

FOLO Tip: FIRE is just a net worth target with a deadline attached. FOLO shows the live gap between where you are and that number, so you are tracking progress rather than recalculating the goal every year.
