FIRE Financial Independence Guide | Start by managing income and expenses, building savings and practical strategies

Financial independence is, I believe, a common goal for many office workers. Yet when asked in earnest, “How much are you actually saving each month? How far are you from financial independence?”, many people are unable to answer.

In recent years, the FIRE (Financial Independence, Retire Early) concept, which originated overseas, has drawn more people into reflecting on this question. In fact, achieving financial independence is not as out of reach as it may seem; the problem is often that people focus in the wrong direction—mistakenly believing that the key lies in making quick money. In reality, the starting point of FIRE is first to understand clearly your own monthly income and expenditure. 

FIRE is an abbreviation for Financial Independence, Retire Early. The core concept is to use savings and investments to generate enough passive income from your assets to cover living expenses, thereby reducing or even eliminating reliance on salary income — in other words, what Hong Kong people often refer to as financial freedom.

The key is not “not working”, but having the choice — to do what you want to do, rather than being forced to work because of financial pressure. The key starting point for practising FIRE is actually very simple: first manage your income and expenditure, then talk about investing.

FIRE is not an abstract concept, but a goal that can be calculated.

The 4% rule suggests that if you withdraw around 4% of your assets each year after retirement to cover living expenses, then, under reasonable investment returns, the likelihood of your assets being depleted within about 30 years is relatively low.

Calculation method:  
FIRE target assets = annual expenditure × 25

Example:  
Annual expenditure HK$240,000 → target assets of approximately HK$6 million

Key point: this figure shows how far you are from financial freedom, rather than planning by intuition.

FIRE is not a one-size-fits-all approach; it can be adjusted according to your lifestyle:

• Lean FIRE: based on low living expenses, with a lower asset requirement, suitable for a minimalist lifestyle  
• Fat FIRE: maintains a higher standard of living, requiring more assets  
• Barista FIRE: a semi-retirement model that retains part of your income and reduces pressure on your assets  

Key point: the most suitable model for you is the one that is sustainable in the long term for FIRE.  

No record of expenditure, managing money by instinct alone

Many people think they are saving money, but in reality their spending structure is unclear, making it easy for “hidden money leaks” to occur.

Save whatever is left, and you will never save enough

Savings become whatever remains at the end, and the result is naturally an inability to accumulate assets. The problem is not willpower, but order.

Misconstruing investment as a shortcut

Overlooking cash flow management, even if investments deliver returns, it is still difficult to build a stable asset base.  

1. Build a basic income and expenditure statement to understand your true financial position

To start planning for FIRE, the first step is not investing, but getting a clear picture of your financial position. Begin by breaking down your monthly finances:

• Income: salary, bonuses, other income  
• Expenses: fixed (rent, insurance) vs variable (food, entertainment, shopping)  

The difference between the two is your actual saving capacity.

If you are not sure how to begin, you can use the Investor and Financial Education Council (IFEC) Money Tracker App. This tool is free and easy to use, does not require linking a bank account, and only takes one to two minutes a day to record your spending. If you stick with it for a month, you will truly understand your spending habits for the first time. In addition, the IFEC also runs the “Financial Month” campaign, offering a wide range of financial information and tools. It is ideal for improving basic financial knowledge and helping you manage your income and expenditure more systematically.

2. Identify spending black holes and reduce unconscious leakage

When you start recording your expenses, you will quickly identify the problem areas. For many people in Hong Kong, the biggest threat to savings is not large expenses, but small yet frequent outgoings such as eating out, takeaway, subscription services, or impulse purchases. Each individual amount may be small, but over time they can steadily eat into your savings.

3. Calculate your savings rate and set a quantifiable FIRE goal

Once you understand your income and expenditure, you can calculate your savings rate, namely the proportion of your monthly income that you save. Generally speaking, 20% is a basic level. If you can reach 50% or more, your savings will grow much faster. However, there is no need to aim for a high percentage from the outset. Even starting at 10% is a good beginning. The key is consistency, not overnight success.

4. Set up a savings mechanism to make saving a default behaviour

The next step is to turn saving into a habit. The simplest way is to automatically transfer a portion of your income after payday, following the principle of “save first, spend later”, rather than saving only what is left over. As long as you do this every month, even if the amount is not large, it can gradually build up into a substantial sum over the long term.

If you are not yet familiar with investing, you may wish to consider more stable options first, such as short-term savings insurance. These products generally have a term of 3 to 5 years and offer relatively stable returns, while also providing basic protection. They can serve as a tool for building a savings habit.

However, please note that early surrender of short-term savings insurance usually results in losses. Policyholders should retain sufficient liquid funds to cover unexpected expenses, and should never put all their money into short-term savings insurance. In addition, the returns of some products include “non-guaranteed returns”, which may not necessarily be achieved. Therefore, you should read the policy terms carefully and understand the composition of the “guaranteed return” and “non-guaranteed return”.

5. Build an emergency fund to provide a safety net for your plan

Before you start investing, it is advisable to save up 3 to 6 months’ worth of living expenses as an emergency fund. This money can cover unexpected situations such as unemployment or medical expenses. With this safety net in place, you will not need to be forced to sell your investments when the market falls.

6. Understand risk and avoid taking the wrong first step in investing

When you begin exploring investments, you need to pay particular attention to risk. The market is full of products claiming to offer “guaranteed profits”, but every investment involves uncertainty. Before making a decision, you should clearly understand the source of returns, fee structure and liquidity of the funds, and make judgements based on your own circumstances rather than relying on friends or falling for scams.  

In the course of pursuing FIRE, beyond saving and investing, it is even more important to understand risk. Many people underestimate these factors, which in turn affects the overall plan.

Inflation: assets may seem sufficient, but may not actually be enough

Prices rise over time, and the cost of living also increases. Even if you calculate a “sufficient” FIRE amount now, its purchasing power may not remain the same in future. For example, if your monthly expenses are $20,000 today, they may already have risen to $25,000 or even more in 10 years’ time. If inflation is not taken into account, your assets may be depleted faster than expected.

Medical expenses: the greatest source of uncertainty

In Hong Kong, medical costs can be very high. If a major illness strikes, expenses can easily run into hundreds of thousands, or even over a million dollars. Without adequate medical protection, a single sudden incident can significantly erode years of accumulated assets.

Once an employee leaves the workforce, employer-provided company medical insurance terminates, and all medical expenses must be borne personally, greatly increasing financial pressure. Even for employees who are still working, the coverage limits of company medical insurance often cannot keep pace with continually rising medical costs, so the protection gap should not be overlooked.

Therefore, it is particularly important to plan personal medical protection early. For example, purchasing Voluntary Health Insurance Scheme (VHIS) for yourself and your family can provide basic medical protection while also offering tax deductions, effectively balancing protection needs and financial planning.

Investment volatility: the market will not keep rising

The investment market will inevitably rise and fall; this is unavoidable. The issue is not market volatility itself, but whether you are prepared for it. If you do not have sufficient cash or emergency funds, and the market falls while you also need money, you may be forced to sell assets at a low point, lock in losses, and affect the entire FIRE plan. 

Many people focus on “how to earn more”, but overlook “how to avoid major losses”. In fact, FIRE is not just about accumulating assets, but also about managing risk:

• Having savings to cope with unexpected events  
• Having protection to transfer risk  
• Having a strategy to respond to market fluctuations  

How can financial freedom be achieved? How much money is needed for financial freedom? 

According to the FIRE concept, the general benchmark is “annual expenditure × 25”. Using annual expenditure of HK$240,000 as an example, the FIRE target assets would be approximately HK$6 million.

Can financial freedom be achieved on a low income?  

Yes, but it requires a higher savings rate and sufficient time for compounding to take effect. The savings rate is more important than the absolute amount of income.

Should you save first or invest first?  

It is recommended to build an emergency fund first (covering 6 to 12 months of living expenses) before starting to invest. If you enter the market without a solid foundation, unexpected expenses may force you to sell assets at an inopportune time, which would not be worth it.

How should salary-to-salary individuals start saving?  

If you spend every month right down to the last dollar, you can start by building a basic savings habit, such as automatically setting aside part of your income after payday, even if the amount is small. At the same time, you may consider some more stable savings products, such as short-term savings insurance. These products offer relatively stable returns and lower volatility, making them suitable as a foundation in the early stages of asset accumulation.
