Key Takeaways

  • FIRE is all about freedom, not simply retiring early. The idea is to have financial independence so that work becomes optional.
  • Spend wisely, not recklessly. All the money you are saving now can go a long way in helping you get more freedom later on.
  • Customise your own FIRE strategy. There is no hard and fast rule. Choose an option that suits your lifestyle.

What is FIRE? The new way to plan retirement 

FIRE means Financial Independence, Retire Early. In basic terms, it is a concept of saving enough money such that your investments will be able to support your way of living.

The goal is not to stop working once you have reached a certain figure. It is about having the flexibility to choose what you want to do going forward. Maybe you will continue working simply because you love it.

Or maybe you decide to start that business you always wanted to, travel, change careers, or just stop worrying about that next paycheck. This is what FIRE is all about.

Less about early retirement and more about getting to the place where money makes options available rather than decisions for you.

How does the FIRE movement work?

The concept is surprisingly straightforward. You spend less than you earn. Invest the difference. Then it is left for compounding to do the rest. As your investments grow, they start to make their own returns.

Eventually, your investments will start working alongside you. The secret lies in your savings ratio. The higher your savings ratio, the lower your reliance on each salary you earn.

This means that it is easier for you to attain financial independence compared to individuals saving a lower percentage of their income.

FIRE is not based on one-time investment. FIRE requires consistent investments.

For many years, early retirement seemed like a dream far away. But now it seems achievable.

People are starting to invest themselves early on. Learning about finances online. Creating various sources of income. Investment decisions being made earlier. Meanwhile, priorities have changed too.

Most people are tired of waiting for decades to retire. They seek the opportunity to be able to take a career break, change their jobs, create their own businesses, and generally control their time. This is precisely why the question of what is FIRE has become such a hot topic in recent times.

It’s not only about early retirement. It’s about the ability to retire at a time and in the way you like without being financially controlled.

How much money do you need?

There is no right number. The 25x rule is a popular guideline in the field of FIRE. It recommends creating a retirement fund that is 25 times your annual expenses.

For example:

Annual expenses: ₹8 lakh

FIRE target: ₹2 crore

Another commonly used rule is the 4% rule, according to which you can withdraw 4% of your investment portfolio per year to meet your expenses.

Such figures serve as guides and not promises.  Your needs will be impacted by your lifestyle, inflation, taxes, and investment returns.

In case, you are keen on calculating you FIRE number, we have a calculator just for you.

Different types of FIRE

Not everyone desires the same type of retirement. Some people enjoy a simple life, and others would like to keep living their normal lives and even work part-time. Thus, there are various strategies to achieve FIRE.

Standard FIRE

This is the traditional FIRE objective. Your investments bring in enough income that you don't need to have a salary.

One of the ways of estimating this objective is creating a retirement portfolio which is around 33 times your inflation-adjusted annual expense.

Lean FIRE

This option is suitable for those who do not mind living a basic yet economical life once retired from their jobs. The approach aims to ensure minimal spending and investing money only on necessities.

On average, the corpus needed is about 25 times the annual inflation-adjusted expenses.

Fat FIRE

Fat FIRE is meant for individuals who seek to become financially independent without compromising on their lifestyle. 

It permits higher costs related to travelling, hobbies, dining out, health care, and other luxuries.

Since the anticipated expenditures are greater, the required amount of money in retirement increases to about 50 times annual expenses adjusted for inflation.

Barista FIRE

Barista FIRE is the combination of financial freedom and flexible work. As opposed to investing solely for your future, you still generate income in the form of freelance work, consulting, part-time jobs, or any passion activity.

The corpus that you need to invest is lower because your investments will have to cover only a portion of your expenses.

The investments should be enough to cover 70% of the total cost, and the other 30% should be generated through income.

How to start your FIRE journey

If you want to follow the FIRE approach, then start small. 

  • Watch out where all your money goes each month.
  • Begin by creating an emergency fund.
  • Make regular investments in SIPs or other suitable investment avenues.
  • Make sure that you increase your investments with every pay rise.
  • Evaluate your progress annually rather than expecting instant success.

You don’t need to save 70% of your earnings right away. What matters much more is consistency over perfection.

Final thoughts

FIRE is not an overnight escape from work. It is about achieving sufficient financial independence to be able to choose your own life.

No matter if you retire at age 40 or keep working by choice, or simply feel peace of mind knowing that your finances back you up in the future, the act of actually doing it all helps in forming good financial habits.

Having understood what is FIRE you can now refer to it as a mindset and not just a retirement plan. The concept is to make smarter financial decisions now to enjoy more financial freedom later.
