FAQ
What is the 4% rule?
The 4% rule states that withdrawing 4% of your retirement portfolio annually allows your assets to last 30+ years. Derived from the 1998 Trinity Study, it means your retirement target = annual expenses ÷ 0.04. For example, if you need ₩2M/month, your target is ₩600M.
What is FIRE?
FIRE stands for Financial Independence, Retire Early. It's a movement centered on achieving economic freedom through high savings rates and investment returns, allowing people to retire well before the traditional retirement age.
What investment return rate should I use for a realistic estimate?
The long-term average return for the Korean stock market (KOSPI) is around 7–8%, and for the US S&P 500 it's around 10%. After adjusting for inflation, the real return is roughly 4–5%. A conservative estimate of 5–7% is recommended.
Should I include severance pay in my current assets?
Yes, it's recommended. Including all assets that can be liquidated at retirement — such as severance pay, pension savings, IRP accounts, and real estate — will give you a more accurate result.
What's the difference between Lean FIRE and Fat FIRE?
Lean FIRE means retiring on 80% of your current living expenses by cutting back. Regular FIRE maintains your current lifestyle. Fat FIRE means retiring with 150% of current expenses for a more comfortable lifestyle. Since the target assets differ, the retirement timeline varies significantly.
