# FIRE Calculator India — free, no login

Financial Independence, Retire Early — the corpus you need, and how long it takes to get there. Inflation-adjusted, in rupees. Free, instant, no signup. Interactive calculator at https://spenco.ai/tools/fire-calculator

Inputs: monthly expenses today, monthly investment, corpus already invested, expected return, inflation, and safe withdrawal rate. Defaults are ₹60,000 monthly expenses, ₹50,000 monthly investment, ₹10,00,000 existing corpus, 12% return, 6% inflation, 4% withdrawal rate.

## How the FIRE number works

The idea is simple arithmetic. If you can withdraw a fixed percentage of an invested corpus every year without exhausting it, then the corpus you need is your annual spending divided by that percentage. At 4%, that is 25 times your annual expenses. Spend ₹6 lakh a year and the number is ₹1.5 crore.

The complication is that the target does not stand still. Twenty years of 6% inflation roughly triples what the same lifestyle costs, so the corpus you need in year 20 is far larger than 25 times what you spend today. This calculator inflates the target each year and reports the first year your projected corpus overtakes it — which is why the headline number is bigger than a naive 25x.

## The two assumptions that matter most

**Inflation.** India has generally run hotter than the developed markets the original FIRE research was based on. If much of your spending is rent, healthcare or school fees, your personal inflation may outpace headline CPI. Try 7 or 8% and see how far the date moves.

**Withdrawal rate.** Dropping from 4% to 3% does not increase the corpus you need by a quarter — it increases it by a third, because you are dividing by a smaller number. For a retirement that might last forty years, many Indian planners prefer 3 to 3.5%.

## What this leaves out

Tax on withdrawals and capital gains. EPF and NPS maturity and lock-in rules. One-off costs like a house or a child's education. And sequence risk — the model assumes the same return every single year, which no real portfolio delivers. A bad first decade after retiring hurts far more than the same bad decade in the middle.

Treat the output as the shape of the problem, not a plan.

## Getting there starts with the monthly number

Every FIRE projection rests on one input you have to be honest about: what you actually spend in a month. Most people underestimate it, because the small recurring things are the easy ones to forget.

## Common questions

**What is a FIRE number?**
The corpus you need invested so that withdrawing from it covers your annual expenses indefinitely. At a 4% safe withdrawal rate it works out to 25 times your annual spending — ₹6 lakh a year of expenses needs ₹1.5 crore. This calculator inflates that target to the year you actually reach it, which is why the number it shows is larger than 25x your spending today.

**Is the 4% rule valid in India?**
Treat it as a starting point rather than a law. The 4% figure comes from US market history, and Indian inflation has generally run higher than the US inflation those studies assumed. Many Indian planners work with 3 to 3.5% for a long retirement.

**What inflation rate should I assume for India?**
6% is a reasonable long-run default for Indian CPI, and it is the value this calculator starts with. Personal inflation is often higher than headline CPI if a large share of your spending is education, healthcare or rent.

**Does the FIRE number account for inflation?**
Yes. Your expenses are inflated each year, so the target corpus rises every year too. FIRE is reached the first year the corpus overtakes a target that is itself still moving.

**What does this calculator not include?**
Tax on withdrawals, capital gains, EPF and NPS maturity rules, one-off costs, and market sequence risk. It assumes a single steady return every year.

**Is this FIRE calculator free?**
Yes — free, instant, and no signup. Nothing you type is sent anywhere; the whole calculation runs in your browser.
