FIRE Through Overseas Relocation: Asset Risk Revealed by Monte Carlo Analysis

For those pursuing FIRE (Financial Independence, Retire Early), overseas relocation is a powerful option. Moving to a country with lower living costs can dramatically reduce the assets needed for FIRE.

Assets Needed for FIRE

FIRE's foundation is the "4% rule" — build 25x your annual expenses, and investment returns sustain your lifestyle.

• Japan (¥3M annual expenses): ¥75M needed
• Malaysia (¥1.8M annual expenses): ¥45M needed
• Thailand (¥1.5M annual expenses): ¥37.5M needed

Simply changing your destination creates tens of millions of yen in difference.

What Is Monte Carlo Analysis?

However, the "4% rule" is based on historical US stock market data with no guarantee of future performance. This is where Monte Carlo analysis helps.

Monte Carlo analysis runs 1,000 simulations with random variations in investment returns and inflation. The results show "will assets survive worst-case scenarios" and "what's the probability of losing principal."

Risks Revealed by Simulation

Consider this example:

Age 35, ¥20M savings, relocating to Malaysia:

• Median (50th percentile): ¥52M at age 60
• Pessimistic (10th percentile): ¥18M at age 60
• Principal loss probability: 8%

Whether that 8% risk is acceptable depends on your personal risk tolerance. If concerned, consider slightly reducing expenses or securing part-time income.

Using MoveWorth for FIRE Planning

1. Input current savings and income
2. Input destination living costs (rent and expenses separately)
3. Set investment return rate (conservative 4-5% recommended)
4. Set period to "FIRE target age minus current age"

Check the results graph for when you reach your FIRE target amount.

Conclusion

FIRE combined with overseas relocation is attractive, but understanding risks is crucial. Use MoveWorth's simulation to verify whether your FIRE plan is realistic.
