There are a few reasons ‌your VantageScore may be lower than your FICO score. First, the two scoring models utilize different sets of information to calculate your score. Second, they weigh each factor differently. (Something greatly influencing your FICO score may have had a lesser impact on your VantageScore.) Additionally, the VantageScore model updates more frequently than the FICO Score model, so your score may change more often as a result.
