What Insurance Is and Why It Exists
Insurance is a way for many people to share the cost of rare, expensive events so no one person has to face them alone.
Insurance is shared risk
Insurance is an agreement where you pay a company a regular amount, and in return the company agrees to help pay for certain large, unexpected costs if they happen to you.
It exists because some events, like a car crash or a serious illness, can cost far more than most people could pay at once. Insurance turns a rare, huge cost into a small, steady one you can plan for.
Premium and deductible
Two words come up in almost every insurance plan. Knowing them makes any policy easier to understand.
- Premium: the regular amount you pay to keep the insurance active, often monthly.
- Deductible: the amount you pay yourself first, before the insurance starts covering a cost.
For example, if a plan has a 500 dollar deductible and you have a 2,000 dollar covered repair, you pay the first 500 and the insurance helps with the rest, based on the plan's terms.
How risk pooling works
Risk pooling is the idea at the heart of insurance. Many people each pay a premium into a shared pool. In any given year, only a few of them will have a major event and draw money out of the pool.
Common types in plain terms
You will run into several kinds of insurance as you go through life. They all follow the same shared-risk idea, just for different events.
- Health insurance: helps pay for doctor visits, medicine, and hospital care.
- Auto insurance: helps pay for damage or injury from a car crash, and is required to drive in most places.
- Renters insurance: helps replace your belongings if they are stolen or damaged in a place you rent.
