When you buy home insurance, you probably expect it to pay the full cost of any damage covered by the policy (minus any deductibles). But if you haven't followed the 80% rule (also known as the 80/20 rule), you might be in for an unpleasant surprise.
Used by most insurers, the 80% rule determines whether your insurance will cover the claims you make in full. If your policy doesn't follow the rule, you might only receive a partial payout for any damage.
