Retirement Planning & FIRE

🎯 Why Plan for Retirement?

Thais are living longer — average life expectancy is 80, but retirement at 60 means 20 years without work income. Without planning, you may run out of money when you need stability most.

💰 The 4% Rule

The golden rule from the Trinity Study (1998): "Withdraw 4% of your portfolio in the first year of retirement, then adjust for inflation each year" — 95% chance your money lasts 30 years.

Example: 10 million baht portfolio → withdraw 400,000 baht/year (33,333 baht/month)

Reverse calculation: if you want 50,000 baht/month (600,000/year) → you need 15 million baht.

🔥 FIRE (Financial Independence, Retire Early)

A movement started in the US — save aggressively, invest early, retire at 40-50:

  • FIRE Number = Annual expenses × 25 (per the 4% rule)
  • Example: spend 500,000/year → FIRE Number = 12.5 million
  • Savings rate 50%+: accelerates wealth-building dramatically

Variants: Lean FIRE (low spending), Fat FIRE (high spending, big portfolio), Barista FIRE (partial retirement + part-time work)

📊 Safe Withdrawal Rate (SWR)

The "safe" withdrawal rate — not running out of money before you die. Factors that affect it:

  • Retirement duration: 30 years → 4%, 50 years → 3-3.5% (safer)
  • Asset allocation: more stocks = higher returns but more volatility; more bonds = stable but lower returns
  • Sequence of Returns: if the market crashes in the early years of retirement = most dangerous

🎢 Glide Path

A strategy to gradually reduce equity allocation as you approach retirement — to reduce the risk of a market crash when you "don't have time to recover":

  • Age 30: 80% stocks, 20% bonds
  • Age 50: 60% stocks, 40% bonds
  • Age 60 (retirement): 40% stocks, 60% bonds
  • Age 70+: 30% stocks, 70% bonds

🇹🇭 Thai Retirement Tools

  • RMF funds — tax-deductible, forced retirement savings (hold until 55)
  • SSF funds — tax-deductible, 10-year hold
  • Provident Fund (PF) — employer-contributed
  • Pension life insurance — tax-deductible, pays annuity
  • Social Security pension — received at age 55 (with continuous contributions)
  • Elderly allowance — government pays 600-1,000 baht/month (age 60+)

📋 Retirement Planning Checklist

  1. Estimate your expected retirement expenses (typically 70-80% of pre-retirement)
  2. Calculate your FIRE Number (× 25)
  3. Assess income you'll receive (pension, social security, interest)
  4. Calculate the "gap" = expenses − guaranteed income
  5. Plan investments to fill that gap (DCA into RMF/SSF funds)
  6. Review annually and adjust to circumstances
