Insurance basics: protecting against big risks
Learner can identify which large, low-probability risks are worth insuring against.
What insurance is — and what it is not
Transferring catastrophic risk
Insurance is a tool for transferring the financial impact of rare but potentially devastating events from you to an insurance company. The logic is straightforward: you pay a regular premium (a smaller, predictable sum), and in exchange the insurer covers a large unexpected loss if a covered event occurs. This makes sense precisely because the loss would be too large for most people to absorb on their own — a serious illness, a long-term disability that stops you from working, a house fire, or a lawsuit.
The risks worth insuring against share two characteristics: they are low probability and high financial impact. Health emergencies, disability or loss of income, liability (accidentally causing harm to others), damage to your home or rental, and life insurance if others depend on your income — these are the core categories. You do not need insurance for losses you could easily absorb yourself. Insuring a cheap appliance, a low-value phone, or minor home repairs is usually not worth the premium cost; pay those out of your emergency fund or savings.
Two concepts help you use insurance efficiently. A deductible (also called an excess in some countries) is the amount you pay yourself before insurance kicks in. Choosing a higher deductible lowers your premium — it makes sense if you could cover that amount from savings. Over-insuring small risks is a common and expensive mistake.
Important: specific insurance products, required coverage, costs, and regulations differ enormously by country. This lesson covers the principles. Always check the rules and options available where you live before making any insurance decisions.
