ORLANDO, Fla. (Ivanhoe Newswire) – Only one percent of Americans have the perfect credit score of 850. Your credit score can affect your ability to buy a home, a car, and even whether you land a new job. Payment history and credit utilization, or the ratio of credit being used compared to total credit available, are the two biggest factors in determining your credit score. The next factors that affect your credit score are length of credit history, new credit inquiries, and diversifying your credit with a mix of credit cards and loans can boost your credit. Too much new credit at one time can affect your credit score negatively by adding hard inquiries to your credit report.
