How insurance works

Risk transfer, premiums, fixed-benefit vs reimbursement cover, claims, and exclusions.

Direct answers

Insurance transfers a defined financial risk to an insurer for a premium; it pays only for the events, people, property, and periods the contract specifies.

Key points

  • Only losses defined in the contract are covered — not every misfortune.
  • Fixed-benefit policies pay a set amount; indemnity policies reimburse actual loss up to a limit.
  • Premiums, exclusions, waiting periods, and definitions decide whether a claim pays.
  • The policy wording (約款) and warning information — not the brochure — control.

What you are actually buying

You are buying a contractual promise to pay under stated conditions, not protection against all loss. Read the definition of the insured event, the exclusions, and any waiting period before you compare price. A cheap policy that excludes your real risk is not cheap.

The core decision rule

Insure a risk only when three things hold at once: the event would cause serious financial harm, the event is uncertain, and a reasonably priced contract actually covers it. Use savings for predictable, affordable costs.
