Both types of score represent different models used to predict how likely it is that any given consumer will be at least 90 days behind on a bill sometime in the next two years. Because they give different weights to the various components in their calculations, the scores they return can be different for the same individual. For example, to get a FICO score, you need to have at least one credit account that's six months "old" or more, but a VantageScore only requires you to have one active account (even if it's not six months "old" ).
