What is a FIRE Calculator?

A FIRE calculator helps you figure out how much money you need to save in order to retire early and live off your savings without ever running out of money. It’s based on a simple formula that factors in your annual expenses and a safe withdrawal rate.

The concept behind FIRE is simple: you need to save 25 times your annual expenses. Once you hit that number, you can safely withdraw 4% of your savings each year to cover your living expenses.

How to Use a FIRE Calculator

The process is simple:

1. Know your yearly expenses: First, determine how much you spend annually on housing, groceries, entertainment, travel, and everything else.
2. Set your safe withdrawal rate: This is the percentage of your savings you can withdraw each year without running out of money. Most people use a 4% withdrawal rate, but some prefer a more conservative rate of 3% or 3.5%.
3. Calculate your FIRE number: Multiply your annual expenses by 25 (based on the 4% rule). This is your FIRE number, which tells you how much money you need to retire early.

For example:

• If your yearly expenses are ₹10,00,000 and your withdrawal rate is 4%, your FIRE number would be: 10,00,000×25=₹2,50,00,00010,00,000 \times 25 = ₹2,50,00,00010,00,000×25=₹2,50,00,000 This means you need ₹2.5 crore saved up in order to retire and safely live off your investments.

Examples of How a FIRE Calculator Works

Example 1: The Frugal Family

Imagine a family that spends ₹8,00,000 a year. They plan to use the 4% rule to retire early. Using the FIRE calculator:

• Annual Expenses: ₹8,00,000
• FIRE Number: ₹8,00,000 × 25 = ₹2 crore

To retire early, they need ₹2 crore saved up. If they currently have ₹1 crore saved, they still need to accumulate ₹1 crore before hitting their FIRE goal.

Example 2: The High Earner

Now consider someone who spends ₹20,00,000 annually. They’re a high-income earner and want to retire early using a more conservative 3% withdrawal rate. Let’s calculate their FIRE number:

• Annual Expenses: ₹20,00,000
• FIRE Number: ₹20,00,000 × 33.33 (based on 3%) = ₹6.67 crore

This person will need to save ₹6.67 crore to achieve financial independence.

Achieving FIRE in India: Things to Consider

While the FIRE calculator works worldwide, achieving FIRE in India can come with unique considerations:

1. Inflation: India’s inflation rate can be higher than that in Western countries, so you may want to build in a buffer by aiming for a higher FIRE number.
2. Healthcare costs: As you retire early, healthcare expenses can be a significant part of your budget, so consider including health insurance premiums in your expenses.
3. Real estate: If you own a home, your yearly expenses might be lower, but if you plan on renting, ensure that rental inflation is factored into your calculations.

How to Stay on Track with FIRE

Once you’ve calculated your FIRE number, the journey doesn’t stop there. You need to continue saving, investing wisely, and keeping your expenses in check. Here’s how you can stay on track:

• Track your expenses: Use tools and apps to monitor where your money goes. Keeping a budget is key to maintaining your savings goals.
• Invest wisely: Focus on long-term investments like index funds, real estate, or mutual funds. The power of compounding will help you reach your FIRE number faster.
• Stay disciplined: It can be tempting to splurge once you start saving, but keep your FIRE goals front and center. Every rupee you save is a step closer to financial independence.
