Overinsurance refers to a situation where an individual or entity has insurance coverage in excess of the actual value of the property or asset being insured. This condition arises when the policyholder purchases insurance policies with limits that are higher than the financial loss the policyholder would incur if a covered event, such as damage or loss, were to occur. Overinsurance can lead to unnecessary higher premium costs, as the policyholder is essentially paying to insure value that does not exist. Moreover, in the event of a claim, the insurance company may only reimburse the policyholder for the actual value of the loss, not exceeding the insured value, which can render the extra coverage moot. This can result in economic inefficiency and is generally advised against because it does not provide additional benefits to the policyholder despite the higher insurance costs.
