A method for protecting a down-payment value associated with a purchase of a depreciating asset is disclosed herein. The depreciating asset may be identified, the purchase of the depreciating asset may be initiated, one or more characteristics associated with the purchase of the depreciating asset may be identified, and the down-payment value associated with a purchase of the depreciating asset may be acquired. At least one of one or more adjustment models corresponding to the purchase of the depreciating asset may be selected. And, a percentage of the down-payment value associated with the purchase of the depreciating asset may be calculated based at least in part on the at least one of the one or more adjustment models. A payment amount may be generated based upon at least the calculated percentage of the down-payment value associated with the purchase of the depreciating asset.
