FIRE Calculator
Financial independence, retire early: your FI number, the age you reach it, or the SIP you need to get there.
Your inputs
What do you want to find?
Everything your household spends in a year, at today’s prices.
AMFI limits illustrative returns to 2–13% a year.
3.5% is a common figure for India: inflation here is higher than in the US data behind the 4% rule, and an early retirement may need to last 40+ years.
Advanced settings
How the yearly return is applied
Most apps divide the yearly return by 12, which shows about 3.5% more over 10 years. We use the effective rate by default, so 12% means 12% a year.

Assumptions and method
Formula
- FI number = annual expenses / safe withdrawal rate
- Expenses grow with inflation: E · (1 + π)^years
- Years to FI = first month the projected corpus ≥ inflated FI number
- After FI: each year's inflated expenses are withdrawn at the start of the year; the rest earns the post-FI return
Conventions used
- Monthly rate: i = (1 + r)^(1/12) − 1 (Effective (12% = 12% a year))
- Money moves at the start of each month, so an instalment earns that month's return.
Modelling notes
- FI number = annual expenses / safe withdrawal rate (3.50%), in the money of the FI date (inflation 6.0%).
- Return 12.0% while saving and 8.0% after FI.
- After FI, each year's expenses (growing with inflation) are withdrawn at the start of the year, until age 90.
Not included
- Market ups and downs: the same return is assumed every month.
- Expense ratio, exit load and stamp duty, unless your expected return already allows for them.
- Income tax on gains (turn on the post-tax option to estimate it).
This is an illustration based on the return you entered. Actual returns vary and may be lower or negative.
Mutual fund investments are subject to market risks, read all scheme related documents carefully.
How it works
FIRE (financial independence, retire early) means having enough invested that your yearly expenses can come out of the corpus for the rest of your life. Your FI number is your annual expenses divided by a safe withdrawal rate: at 3.5%, that is about 28.6 times a year’s spending.
Choose When can I be FI? to see the age your monthly SIP gets you there, or What SIP do I need? to work back from the age you want. Expenses grow with inflation, so the FI number in the future is larger than today’s.
After FI, the calculator withdraws each year’s (inflation-rising) expenses and lets the rest earn the post-FI return, to show how long the money lasts.
Frequently asked questions
Why 3.5% and not the 4% rule?
The 4% rule comes from US market history with lower inflation and a 30-year retirement. Indian inflation is higher and an early retirement may last 40–50 years, so 3–3.5% gives more margin.
What return should I assume after FI?
Lower than while saving, because part of the money usually moves to debt and hybrid funds for stability. 7–8% is a common planning figure; returns are not fixed and can be negative in some years.
Does the FI number include taxes?
No. Use your post-tax spending, and add a margin for tax on withdrawals, health cover and one-off costs.
What return should I assume?
Use a figure you would be comfortable with if markets disappoint. For diversified equity funds over 10+ years, 10–12% a year is a common planning assumption; debt funds 6–7%. Returns are not fixed, can be negative over short periods, and past performance may or may not be sustained in future.
