Retirement Planning Basics: Questions Before Numbers
更新于: · 7 min · 进阶
Before estimating a retirement number, define the life you are saving for. A calm framework for replacement rates, withdrawal rules, and uncertainty.
What are you funding?
Retirement is not one event but a multi-phase life: active early years, slower later years, and potentially significant late-life care costs. Housing decisions, location, and whether some work continues shape the number far more than return assumptions.
Replacement rates and the 4% guideline
Replacing 70–85% of pre-retirement income is a common shortcut, but your spending is the real input. The 4% withdrawal guideline comes from historical portfolio survival studies in one country and one period; different fees, market conditions, and flexible spending change outcomes.
Plan around uncertainty
Run conservative, base, and optimistic scenarios. Stress-test against inflation shocks, a decade of low returns, and a long life. A plan that survives bad assumptions is more useful than a precise single number.
Accounts and tax rules vary by country
Tax-advantaged retirement accounts and employer matching can be powerful, but rules differ across jurisdictions and change over time. Use official sources and a licensed adviser; AILICAI educates on concepts and never recommends specific accounts or funds.

「教育」和「建议」有什么区别？
教育讲的是一个概念或公式在一般情况下如何运作；建议则是告诉你个人该买什么、该做什么。AILICAI 只提供前者，后者建议你咨询持牌专业人士。
为什么收益要标注为「假设」？
因为没人能预知未来收益，而画一条平滑上升的曲线很容易误导。这里所有推演都是你可以调整假设的模拟，不是承诺。
