RY: Too many of your revolving credit accounts have high utilization.
Revolving accounts allow you to carry a balance and your monthly payment will vary, based on the amount of your balance. You have revolving credit accounts in your credit file with balances that are high compared to the credit limit on the account, which is a proven indicator of increased risk.
Pay down balances on your accounts and keep them below 30% of the total credit limit on that account. Over time this will have a positive impact on your score.
