Insurance Basics: Protecting the Plan You Built
更新于: · 6 min · 入门
Insurance exists to prevent rare but catastrophic losses from wiping out years of saving. A plain-language guide to the categories most households encounter.
What insurance is actually for
The economically rational use of insurance is trading a small, predictable cost for protection against large, rare losses you cannot self-fund. Extended warranties on cheap goods reverse this logic — they insure small losses at high relative prices.
Common categories
Health coverage protects against medical catastrophe; disability insurance replaces income if you cannot work (statistically more relevant to young workers than life cover); term life insurance protects dependents who rely on your income; property and liability coverages protect home, vehicle, and legal exposure.
Needs vary enormously by country, family structure, and local law — this is general education, not a recommendation to buy a particular policy.
Reading a policy
Compare more than premiums: the deductible you must pay first, the benefit limits, and especially the exclusions. A cheap policy that excludes the event you fear is expensive peace of mind for nothing.
Avoiding common mistakes
Buying only after risk rises means coverage may be unavailable or unaffordable. Letting coverage lapse silently, and failing to update beneficiaries after life changes, are two of the most common and fixable errors.

「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。
