Understanding Coinsurance

What is Coinsurance?

Coinsurance is a clause in your insurance policy that requires you to carry coverage equal to a specified percentage of your property's value (typically 80-90%). If you don't meet this requirement, you may face penalties when filing a claim.

The Penalty

If you're underinsured, the insurance company will reduce your claim payment proportionally. For example, if you only carry 50% of the required coverage, you'll only receive 50% of your claim amount (minus deductible).

How to Avoid Penalties

1. Regularly review your coverage limits
2. Update your policy when property values increase
3. Consider guaranteed replacement cost coverage
4. Consult with your insurance agent annually
