FICO Scores are calculated from a lot of different credit data in your credit report. This data can be grouped into five categories as outlined below. The percentages in the chart reflect how important each of the categories is in determining your FICO score.
These percentages are based on the importance of the five categories for the general population. For particular groups - for example, people who have not been using credit long - the importance of these categories may be somewhat different.
