Your credit score is calculated based on five factors: payment history, credit utilization, length of credit history, credit mix, and new credit. Different types of credit can affect your score differently, depending on how you use them. Payment history is the most important factor, accounting for 35% of your score. It reflects how well you pay your bills on time. Credit utilization is the second most important factor, accounting for 30%. This measures how much of your available revolving credit you are using. Length of credit history accounts for 15%, and it looks at the average age of your accounts and the oldest account on your report. Credit mix accounts for 10%, and it shows how diverse your portfolio of credit is. Finally, new credit accounts for 10%, and it looks at how many new accounts you have opened or applied for in the past 12 months. Having a mix of different types of credit can boost your score, but opening new accounts just to improve your mix can also affect other factors negatively. Hard inquiries can temporarily lower your score by a few points, so you should be careful when applying for multiple types of credit in a short period of time.
