Insurance Basics: Protecting the Plan You Built
업데이트: · 6 min · Beginner
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.

What is the difference between education and advice?
Education explains how a concept or formula works in general. Advice recommends what you personally should buy or do. AILICAI provides only the first, and suggests a licensed professional for the second.
Why are returns labeled hypothetical?
Because no one can know future returns, and showing a single smooth growth line can mislead. All projections here are simulations you control — not promises.
