What percentage is typically required for coinsurance on dwelling fire and homeowners policies?

In property insurance, particularly for dwelling fire and homeowners policies, a common coinsurance requirement is set at 80%. This means that the policyholder must insure the property for at least 80% of its replacement cost. The purpose of this requirement is to encourage policyholders to adequately insure their properties, thus ensuring adequate coverage in the event of a loss.

If a property is underinsured and suffers a loss, the policy may only pay a pro-rated amount based on the level of coverage maintained relative to the coinsurance requirement. By adhering to the 80% threshold, policyholders can avoid significant financial penalties in the event of a claim and ensure that they receive a fair payout that reflects their investment in the property.

If the coinsurance percentage were set lower, such as 50% or 75%, it might not sufficiently protect insured homes against the risk of catastrophic loss, as many properties could be underinsured. Conversely, a requirement of 100% may create excessive financial strain for policyholders who are required to insure for the full replacement value, rather than the more typical benchmark of 80%. Thus, the 80% coinsurance requirement strikes a balance between protecting insurers and ensuring fair coverage for policyholders.
