What Is FIRE?

FIRE stands for Financial Independence, Retire Early.

It is a financial strategy focused on:

• Aggressive savings
• Consistent investing
• Controlled expenses
• Achieving early retirement

The goal is to build a large enough investment corpus so that investment returns can fund your living expenses permanently.

What Is the FIRE Number?

Your FIRE number is the total corpus required so that you can withdraw money every year without running out of funds.

The formula used:

Annual Expenses ÷ Safe Withdrawal Rate

If your annual expenses are ₹6,00,000 and you use a 4% withdrawal rate:

FIRE Corpus = 6,00,000 ÷ 0.04 = ₹1.5 crore

This calculator automatically computes that target based on:

• Your monthly expenses
• Your selected withdrawal rate
• Inflation

Inputs Used in This FIRE Calculator

Current Age

Your present age. This determines how many years you have before your desired retirement age.

Current Savings

Total amount already invested across all assets.

Monthly Expense

Your current lifestyle cost. This becomes the base for inflation-adjusted retirement needs.

Monthly Investment

How much you invest every month toward financial independence.

Expected Return

Annual expected investment return. Used for compounding portfolio growth.

Inflation

Annual inflation rate. Used to increase your future expense target.

Advanced Options

Safe Withdrawal Rate (SWR)

This determines how much of your portfolio you can withdraw yearly without running out of money.

Common benchmarks:

• 4% is widely used
• 3–3.5% is conservative
• 5% is aggressive

The calculator automatically adjusts your required corpus using this rate.

Retirement Age

You can set a target retirement age.
The calculator checks whether your portfolio crosses the FIRE target before or by that age.

How the FIRE Calculation Works

The calculator runs a yearly simulation:

1. Portfolio grows monthly using compound interest
2. Investments are added each month
3. Expenses grow annually with inflation
4. Required corpus increases with inflation
5. Once portfolio exceeds required corpus, FIRE is achieved

It shows:

• The exact year you reach financial independence
• Age at FIRE
• Inflation-adjusted expenses at that time
• Yearly progress table

Example

Suppose:

• Current age: 30
• Current savings: ₹10,00,000
• Monthly expense: ₹50,000
• Monthly investment: ₹30,000
• Expected return: 12%
• Inflation: 6%
• Withdrawal rate: 4%

The calculator will:

• Estimate your inflation-adjusted future expense
• Calculate your required corpus
• Simulate portfolio growth
• Show the exact age when your portfolio exceeds your FIRE target

It also shows a yearly comparison of:

Portfolio vs Required Target
Status: Working or FIRE
