RC vs ACV
There are several different methods by which your insurance company may calculate the amount it will pay you for a loss. Payment based on the replacement cost of damaged or stolen property is usually the most favorable figure from your point of view, because it compensates you for the actual cost of replacing property. If your camera is stolen, a replacement cost policy will reimburse you the full cost of replacing it with a new camera of like kind. The insurer will not take into consideration the fact that you ran three rolls of film through the camera every day for the last two years, causing a considerable amount of wear and tear.
In contrast, actual cash value (ACV), also known as market value, is the standard that insurance companies arguably prefer when reimbursing policyholders for their losses. Actual cash value is equal to the replacement cost minus any depreciation (ACV = replacement cost – depreciation). It represents the dollar amount you could expect to receive for the item if you sold it in the marketplace. The insurance company determines the depreciation based on a combination of objective criteria (using a formula that takes into account the category and age of the property) and subjective assessment (the insurance adjuster’s visual observations of the property or a photograph of it). In the case of the stolen camera, the insurance company would deduct from its replacement cost an amount for all the wear and tear it endured prior to the time it was stolen.
