Credit score can be affected by five factors. A high credit score can be achieved by disputing incorrect information and maintaining a clean credit history. It may take several years to fix credit histories with many public records or delinquencies.
Credit score of 850
Although it may seem impossible for an individual to have a credit score of 850, it is possible. Experian recently found that approximately one percent of American adults have scores above 850. While it can be tough to maintain a high score, there are a few simple steps you can take to start improving your score.

Hard inquiries
Your credit score is affected by how many new applications you submit each year. These inquiries can reflect your credit shop activity and could be helpful for potential lenders to assess your creditworthiness. Multiple inquiries count as one in most cases, but the period of time will vary depending on which credit scoring model you are using. This is to enable you to compare loans without negatively impacting the credit score.
Age
It is possible to raise your credit score by building a solid credit history. While you can't get to 850 overnight, there are several things you can do to raise your credit score over time. First, you need to take the time and understand your credit history. Your age is only one factor that will affect your credit score. The average credit score of people in their twenties is around 660. 733 is the highest credit score among people in this age group.
Income
The average credit balance of the 850 club's credit score is $32,872 (versus $17.064). This is higher than the average balance for the entire population. This club is dominated by older members. The silent generation and baby boomer generations have the highest proportions of 850 credit score holders. However, millennials and Generation Z only make up 25% of those with 850-plus FICO(r).
Being punctual in paying your bills
One of the most important factors in achieving an 850 credit score is your payment history. Your score will increase if you have a longer payment history. It is vital to make your payments on time. You also need to ensure that there are no outstanding accounts. For obtaining a mortgage or loan, it is important to have a clean payment history.

Maintaining a positive financial attitude
One of the most important things you can do for your credit score is to develop a good financial routine. A high credit score is a sign of your ability to manage both your credit card and your debt. High-scoring people have a long credit history, excellent payment records, and a balance between their available credit and any unpaid balances. These people also use a smaller percentage of their credit limit. Lenders consider these borrowers to be less risky than borrowers with lower credit scores.
