The sale of a vehicle may involve many cost and profit components. It is generally impossible for a potential buyer to know all of these components. For example, dealers may be paid by original equipment manufacturers (OEMs) on their Customer Satisfaction Index (CSI) and volume bonus. Embodiments disclosed herein may determine and present to a user an accurate estimate of dealer cost, taking into consideration an aggregate of dealer cost components. For each component, a predictive model may be built to determine an expected value at a particular level. An average of the expected value of the component is then calculated for the most recent month. From that, an average bonus payout per vehicle for the most recent month may be determined. A base dealer cost is adjusted to account for these payouts to produce an accurate estimate of actual dealer cost.
