Insurance Types Explained
What the main US insurance policies do, what they do not do, and how to choose the coverage you actually need.
Why Insurance Exists
Insurance helps you trade a smaller predictable cost now for protection against a much bigger loss later. You pay a premium, and the insurer helps cover certain risks if something goes wrong.

Life insurance

What Is Commonly Required by Law?
Auto insurance is the main type that is legally required in most states. If you have a mortgage, your lender will also usually require homeowners insurance. Health insurance is no longer federally mandated, though some states have their own rules or penalties.
How to Buy the Right Amount of Coverage
- Protect big risks first: health, auto liability, and your home or belongings.
- Choose a deductible you could realistically cover from savings.
- Compare quotes from multiple insurers before renewing automatically.
- Do not buy tiny policies for losses you could easily pay yourself.
Common Insurance Mistakes
- Choosing the cheapest premium without checking the deductible and exclusions.
- Skipping renters insurance even though it is usually inexpensive.
- Keeping state-minimum auto limits that may be too low after a serious accident.
- Assuming employer coverage alone is enough for every situation.
