FIRE stands for financial independence, retire early: saving and investing enough that your investments can pay your living costs for the rest of your life. This calculator estimates the corpus you need and the monthly investment to get there.
How the FIRE number is calculated
Expenses at FIRE age = today's yearly expenses × (1 + inflation)^years to goFIRE corpus = expenses at FIRE age ÷ safe withdrawal rateMonthly investment = amount needed, after growing what you already have, spread over the years to goThe safe withdrawal rate is how much of the corpus you take out each year. The well-known 4% rule comes from US data over 30-year retirements. Indian inflation is higher and early retirements are longer, so many Indian planners use 3–3.5%, which means a corpus of about 28–33 times yearly expenses.
Worked example
Example: Age 30, ₹6 lakh a year of expenses, aiming to retire at 45
With 6% inflation, expenses at 45 will be about ₹14.4 lakh a year.
At a 3.5% withdrawal rate, the FIRE corpus is about ₹4.11 crore (28.6 times those expenses).
With ₹20 lakh already invested and 10% returns, you'd need to invest about ₹77,000 a month for 15 years.
Making FIRE realistic
- Your savings rate matters more than returns. Cutting expenses lowers both the corpus you need and the time to reach it.
- Plan for health insurance after you leave employer cover; premiums rise with age.
- Keep 2–3 years of expenses in safer assets so a market fall doesn't force you to sell.
- Many people choose 'lean' or 'coast' FIRE: part-time or freelance work that covers some expenses.
In retirement, a systematic withdrawal plan is a common way to draw a monthly income.

FAQs
Why 3.5% and not 4%?
The 4% rule comes from US data. With higher inflation in India, many planners use 3–3.5%, roughly 30–33 times yearly spending.
