• Actual Cash Value (ACV) refers to physical property and auto damage insurance, which is one of several possible methods of determining the value of insured property to determine how much an insurer will pay in the event of a loss. ACV is usually calculated in one of three ways: (1) the cost of repairing or replacing damaged property less depreciation; (2) the “fair market value” of the damaged property; or (3) the use of the “broad evidence rule”, which requires consideration of all relevant evidence of the value of the damaged property.
