Annual Depreciation is an estimation of what your vehicle's value might be over time based on an average of similar vehicles. Estimations are calculated by comparing Kelley Blue Book Private Party Values of vehicles similar to yours over time, as well as forecasts from Manheim Auction data comparing current and projected auction values against current Kelley Blue Book Private Party and Trade-In Values. This is not a guarantee of actual depreciation. Local weather conditions, market factors and driver performance will also impact your vehicle's actual depreciation.
