Frequently asked questions
FIRE stands for Financial Independence, Retire Early. The idea is to accumulate enough invested wealth that the returns alone can cover your living expenses indefinitely.
The 4% rule suggests you can safely withdraw 4% of your portfolio in the first year of retirement, adjusting for inflation thereafter, with a high chance of the money lasting 30+ years. A 4% rate implies a corpus of 25× your annual expenses.
It originates from US market data. Given different return and inflation patterns, some Indian investors prefer a more conservative 3–3.5% rate, which means a larger corpus. Adjust the slider to test scenarios.
Increase your savings rate, invest in growth assets, and keep lifestyle inflation in check. The higher the share of income you invest, the sooner financial independence arrives.
One number, one multiplication: your entire FIRE plan
₹6,00,000 in annual expenses, multiplied by 25, gives a FIRE number of ₹1,50,00,000 — one and a half crore. That's the whole calculation behind the FIRE movement (Financial Independence, Retire Early): find the portfolio size at which a safe annual withdrawal covers your expenses indefinitely, without ever touching the principal, and you no longer need employment income to live.
Why 25 is the multiplier, and why it moves when you adjust the slider
25 isn't an arbitrary round number — it's the mathematical inverse of a 4% withdrawal rate (100 ÷ 4 = 25), the rate popularised by the "safe withdrawal rate" research this calculator's default is built on. Slide the withdrawal rate down to a more conservative 3.5% instead, and the multiplier rises to roughly 28.6× the same expenses — a seemingly small change in the rate that meaningfully raises the target corpus, because a lower withdrawal rate means the same portfolio has to produce a proportionally smaller slice of income each year.
Where the 4% figure actually comes from, and why some investors distrust it
The 4% rule traces back to US historical market data — commonly referenced as the "Trinity study" — and its assumptions don't automatically transfer to Indian markets, which have a different long-run return and inflation profile. That's why some Indian FIRE planners deliberately target a lower 3–3.5% withdrawal rate instead: it demands a larger corpus upfront, but it also builds in a real margin of safety against a bad sequence of returns in the first years of early retirement, which historically does more damage to a withdrawal plan than an unlucky decade in the middle.
The lever that gets you there faster isn't the one people chase
Chasing a higher return is the obvious instinct, but the faster and more controllable route to your FIRE number is usually a higher savings rate — investing a larger share of income rather than hoping for outsized returns on what you already save. Keeping lifestyle inflation in check works on both sides of the equation at once: it grows your invested corpus faster while simultaneously lowering the annual-expenses figure that determines your target in the first place.
