Personal Finance | 001 What is Financial Freedom?

Financial freedom is a goal pursued by many: it means you no longer need to work for money, because your passive income, such as dividends from stock funds, bond interest, rental income, pensions, and Social Security — is equal to or greater than your household expenses. At this point, even if a household member stops earning an income, the family can maintain its lifestyle using only savings and investment returns, effectively becoming “self-insured.”

To estimate the amount of financial assets needed for financial freedom, you can use the well-known: 4% Rule: You can safely withdraw 4% of your investment portfolio each year to fund living expenses — without depleting the principal over time. This rule assumes the underlying investments continue to grow long-term, offsetting inflation and withdrawals.

Financial Assets × 4% + Rental Income + Other Passive Income ≥ Household Current Expenses  x (1+Inflation Factor)^ Years x downsizing rate (80%)

Example:

• Annual living expenses = $100,000
• Rental income = ¥30,000/year
• No other passive income
• ​Inflation Factor=3%
• Years 20 years
• Future Expenses = $100,000 × (1 + 0.03)^{20} × 0.8=$144,488
• (144,488-30,000) /0.04= $2,862,200

Once you’ve achieved financial freedom, you may notice a shift in your mindset and behavior. You’ll experience peace of mind, feeling less anxious about job losses or layoffs, and gain greater emotional and financial security. Additionally, you may have the option to change your investment strategies to focus on maximizing returns and adopting a more flexible asset allocation. With this new perspective, you can also prioritize a better work-life balance.​

“The cost of ignorance is far greater than the cost of knowledge.” Financial freedom isn’t just for the wealthy — it’s for the informed. With the right mindset, tools, and strategy, anyone can move toward a life of autonomy, security, and joy.
