A car depreciation after accident calculator functions by applying formulas and industry standards to generate an estimate of the decreased value of your vehicle. The concept is straightforward and very important: while your car may have been repaired perfectly, it will not have the same resale value as if it had not been in an accident. The calculator will typically look at the original value of the vehicle, the current mileage, the amount of repairs that were completed, and the demand for your vehicle in the market. This example of a vehicle depreciation calculator is very much what insurance adjusters do to calculate how much you will get offered, and this is why you can have an edge by using this type of calculator. You can see how your calculation compares with that suggested by an insurance adjuster, and you can use this to reach a position of knowledge, and fairness, in the negotiation process.
