That single rule decides which policies are worth buying and which are sold on fear.

That single rule decides which policies are worth buying. Insure rare ruinous losses and skip cover for small affordable ones. If you could pay a bill calmly from savings, the policy protecting it is probably a bad buy. **Example.** Compare three risks. A car crash can cost more than years of premiums, so motor cover passes the rule. A scratched phone screen costs little and happens often, so phone cover fails it. An extended warranty on a cheap kettle fails it too, yet it sells at the till through fear. Same shopper, same evening, three different answers from one rule. An excess is the part you pay yourself on each claim, and it moves both price and behaviour. A higher excess means cheaper premiums and fewer tiny claims, because you stop claiming for every scratch. That skin in the game keeps premiums lower for everyone. When comparing policies, weigh four things together: price, cover limits, exclusions and the excess. Read the exclusions first, since they list what the insurer will never pay. **Tip.** Health cover runs on the same shared-cost logic with four terms to learn while healthy, not in a waiting room. A deductible is what you pay first, a copay is the fixed fee per visit, the network sets the prices you face, and the yearly maximum caps your worst year. That cap is the whole point of insurance: it turns an open-ended disaster into a bounded bill. **Recap.** Cover ruin, skip scratches, and read the exclusions first. ## Practice 8 questions on this page, each with its working shown. ## Needs first - [Credit Files and What Lenders See](https://lightmysky.com/learn/life-skills/credit-files-and-what-lenders-see-mt_SfwNy9cOjb) - [A Budget That Survives a Real Month](https://lightmysky.com/learn/life-skills/a-budget-that-survives-a-real-month-mt_tFRHTFelNG) - [Risk, Insurance and Pooling](https://lightmysky.com/learn/civics-and-economics/risk-insurance-and-pooling-mt_zrMeXUHV4Y) ## Opens up - [Starting a Pension at Eighteen](https://lightmysky.com/learn/life-skills/starting-a-pension-at-eighteen-mt_mGfpMq2IAW)
