Wealth Strategy Note | Asset formation roadmap for office workers to get closer to FIRE

[Summary]

This is a strategy note for becoming wealthy. In order for office workers to get closer to FIRE, we will organize the standards for pure financial assets, how to progress from the mass class to the semi-rich class, and how to use the new NISA and stock-type side jobs.

If you look at wealthy people as people with high incomes, it's easy to misunderstand your strategy.

What investors should look at is net financial assets, not annual income. In Japan, based on the Nomura Research Institute's classification, it is widely used that people with net financial assets of 100 million yen or more but less than 500 million yen are classified as wealthy, and those with net financial assets of 500 million yen or more are classified as ultra-rich.

However, even if an office worker suddenly sees 100 million yen, it is too far away. In reality, the key question is how to design a process for people to move from the mass class to the upper mass class and then to the semi-rich class.

The conclusion of this strategy note is simple.

Salary deposit power, long-term operation using the new NISA, stock-type side job. Cultivate these three at the same time.

Get closer to the wealthy class through reproducibility, rather than a one-shot reversal. The same goes for FIRE. Rather than aiming only for early retirement, it is much more realistic to think of using assets to increase your options for work, place to live, and time.

First, the conclusion

If an office worker aims to become wealthy or FIRE, the strategy doesn't have to be flashy.

In fact, the flashier the strategy, the more dangerous it is. Increase your profits all at once through short-term trading, compete with crypto assets and leveraged products, and focus on stocks that are popular on social media. It works for some people, but reproducibility is low.

When considering reproducibility, the order in which you should watch them is as follows.

The path to wealth is not determined solely by how you choose investment products.

The essence is how much you can create a household financial structure that allows you to increase your assets every year.

The standard for wealthy people is “net financial assets”

The term wealthy is often used loosely.

People who drive luxury cars, people with high annual incomes, and people who live in apartments in the city center. It is often talked about in this way, but when it comes to asset building strategies, we want to look at it differently.

What should be the standard is net financial assets.

Key point= Key point

According to Nomura Research Institute's classification, household net financial assets are divided into the following:

It is important to note here that real estate itself is not included in this net financial asset. Rather than looking at whether or not you own a home, look at financial assets that can be immediately used for investment, management, and defense of your life, minus your debts.

Wealth strategy becomes quite realistic the moment you put this definition in place.

This is because we are talking about the balance sheet, not boasting about annual income.

Strategy by current location

If you suddenly aim for ``net financial assets of 100 million yen'', most people will be too far away to move.

So let's separate the stages.

Mass group: First, create a household budget that allows you to continue investing

At the stage of net financial assets of less than 30 million yen, the sustainability of household finances comes before investment yield.

What needs to be done here is simple.

• Understand monthly surplus amount
• Create a life defense fund
• Reduce high-interest debt
• Review fixed costs such as insurance and communication costs
• Start making small savings with the new NISA

The last thing you want to avoid at this stage is thinking, ``I'm going to go big because I don't have a lot of assets.''

The more assets you have, the more important it is not to leave. Investing that would leave you short of living expenses in the event of a market crash is more like speculation than asset building.

First, create a system in which monthly surpluses are automatically invested. This is the foundation.

Upper mass layer: Increase depositing power and operation at the same time

Once your net financial assets exceed 30 million yen, you will begin to feel confident in your ability to build assets.

However, it is easy to become complacent at this stage. Cars, housing, travel, eating out, education expenses. If your expenses increase as your income and assets increase, you will be slower to reach semi-wealthy status.

The asset amount is not the only indicator that should be looked at for the upper mass class.

If you rely only on salary income, it is easy to see the upper limit. Increase your earning power by getting a raise or changing jobs. At the same time, cultivate stock-type side jobs. If we can do this, the perspective on semi-rich people will change.

Semi-wealthy: Turn FIRE into a real option

Once your net financial assets exceed 50 million yen, FIRE is no longer a pipe dream.

However, there is no need to rush to quit the company at this point. In fact, the strength of the semi-wealthy is not that they can quit their jobs, but that they have greater bargaining power over their jobs.

• You won't have to worry about changing jobs
• Makes it easier to turn down jobs you don't like
• Easier to allocate time to side job or business
• You don't have to choose a job based on income alone

The first step to FIRE is not early retirement.

It is the restoration of choice.

At this stage, you'll want to take a look at your annual living expenses, taxes, social insurance premiums, and how to withdraw your money in the event of a market crash. The larger the assets, the more effective a defensive design becomes than an offensive one.

Illustrated: Roadmap for corporate employees to become wealthy

New NISA is “core”, but do not view it as a panacea

New NISA can be easily placed at the core of asset formation for company employees.

Investment profits are tax exempt. Easily diversified with investment trusts and ETFs. Monthly savings can also be automated. The system is quite easy to use.

However, whether you can reach the wealthy class with just the new NISA depends on your deposit strength.

Even with the same yield, a person who can only invest 300,000 yen a year and a person who can invest 3,000,000 yen a year will reach a completely different rate.

What is important here is salary income and side job income.

Rather than chasing investment yield excessively, increase the deposit amount first. This is a simple but very powerful strategy.

Stock-type side jobs are compatible with the FIRE strategy

There are two types of side jobs: those that sell time and those that create assets.

Labor-type side jobs have immediate benefits. Suitable for making initial funds.

However, it is stock-type side jobs that are compatible with the FIRE strategy. The reason is that sales and customer attraction may remain even after time passes.

Blog articles are searched. The video will play. Teaching materials will sell. Templates are continually being purchased. Small services are billed monthly.

Of course it's not easy. For the first six months to a year, it is normal for a company to generate almost no income.

Still, stock-type side jobs have the same characteristics as asset building.

Make it first and it will work later.

This is the difference from salary income.

If you decide to turn investment advice or paid stock recommendations into a side job, you need to be careful about regulations such as the Financial Instruments and Exchange Act. When disseminating information on investment themes, it is best not to be careless about the boundaries between education, general information, personal experiences, and advice.

What is needed for FIRE is understanding living expenses rather than “retirement amount”

FIRE often talks about 25 times your annual living expenses and the 4% rule.

Although it is useful as a guideline, it is rough to apply it directly to Japanese office workers.

Actually,

*Tax

• Social insurance premiums
• Housing costs
• Family structure
• Exchange
• Market environment
• Withdrawal in the event of a crash

The amount required varies considerably.

So the first thing you need to do is not decide on your FIRE amount.

Accurately know your annual living expenses.

The required assets are completely different for people whose annual living expenses are 3 million yen and those whose annual living expenses are 6 million yen. The reason why expense management is so important when it comes to asset building is that lowering the cost of living also lowers the amount of assets needed.

In this sense, saving money is not a matter of patience, but a regulating valve that shortens the distance to FIRE.

Strategy scenario

Bullish scenario

Your salary income will be stable, and your ability to earn money will increase if you get a raise or change jobs. Continue long-term savings with the new NISA and make small profits from stock-type side jobs.

In this case, asset formation is quite strong. You can accumulate assets through yearly deposits and compound interest without relying too much on market prices. The transition from the upper mass class to the semi-rich class will become a reality.

Neutral scenario

You can continue investing, but your deposit power will not increase significantly. Side jobs also take time to become profitable.

Even in this case, if the household budget is in the surplus and the new NISA can be continued, asset formation will move forward. However, the time to FIRE will be longer. It is important not to rush to collect the yield.

Bearish scenario

As living standards rise, there is less money available for investment. They rely on short-term trading and high-risk products, and are forced to cut losses or withdraw when a market crash occurs.

In this case, even if the annual income is high, it is difficult to approach the wealthy class. When it comes to building assets, it becomes difficult when the ability to leave behind collapses before the ability to earn.

Execution checklist

I think this checklist should be looked at before choosing stocks.

No matter how good an investment trust you choose, it won't last if your household budget is in the red. No matter how hard you work on your side job, if you use it all up, it won't become an asset.

Wealth is not just an issue of investment products, but also of systems.

Final judgment

Strategies for office workers to become wealthy or FIRE are not special tricks.

In fact, it's quite plain.

Bring the household budget into the black. Increase your deposit power. The new NISA will be used for a long period of time. Create a stock-type side job. Don't raise your standard of living too high. Don't leave due to a crash.

This accumulation becomes a realistic route from the mass class to the upper mass class to the semi-rich class.

Wealthy people are not people who make extravagant amounts of money, but people who have a structure in which their assets remain.

The same goes for FIRE. It's not just about quitting your job. The essence is to reduce anxiety about money and regain choice.

As a strategy, I would like to think of it this way.

Create a reproducible asset formation system before looking for high yields.

I think this is the most realistic strategy for office workers to become wealthy.
