Credit utilization rate is a measure of how much credit you use relative to your available credit limits. A high credit utilization rate might indicate that you are using more credit than you have available, which could result in higher interest rates or the risk of exceeding your credit limit. It’s important to monitor your credit utilization rate and keep it at a reasonable level to avoid financial risks like debt accumulation or default. You can lower your utilization rate by paying down your balance, increasing your credit limits, or transferring balances to credit cards with lower interest rates.
