Please note that:

A FICO score takes into consideration all these categories of information, not just one or two.

No one piece of information or factor alone will determine your score.

The importance of any factor depends on the overall information in your credit report.

For some people, a given factor may be more important than for someone else with a different credit history. In addition, as the information in your credit report changes, so does the importance of any factor in determining your FICO score. Thus, it's impossible to say exactly how important any single factor is in determining your score - even the levels of importance shown here are for the general population, and will be different for different credit profiles. What's important is the mix of information, which varies from person to person, and for any one person over time.

Your FICO score only looks at information in your credit report.

However, lenders look at many things when making a credit decision including your income, how long you have worked at your present job and the kind of credit you are requesting.

Your score considers both positive and negative information in your credit report.

Late payments will lower your score, but establishing or re-establishing a good track record of making payments on time will raise your FICO credit score.
