When it comes to monitoring a credit score, it is important to pay all bills on time and not max out a credit card when relying on one for holiday spending. However, another factor, known as the credit utilization ratio, plays a major role in a consumer’s FICO score. In fact, this number accounts for 30 percent of the average consumer’s FICO score, and it is the second most important part of a person’s credit score next to paying bills on time.
To figure out what this score is, the consumer needs to add up credit limits across all his or her credit cards and then add up the outstanding balance on each card. Divide the total balance owed by the total limits and multiply that by 100 to determine the percentage or credit utilization ratio.
