常见问题
How much do I need to retire?+
The common rule of thumb is 25x your annual expenses (based on the 4% safe withdrawal rate). If you spend $50,000/year, you need approximately $1.25 million. This historically sustains a 30+ year retirement without running out.
What return rate should I use?+
For a diversified stock/bond portfolio, use 7% (inflation-adjusted) or 10% (nominal). Being conservative (6-7%) is better for planning purposes to avoid nasty surprises from market downturns near retirement.
