It involves getting more credit to improve something called your credit utilization rate, which is simply how much you owe divided by your available credit. This makes up 30 percent of your credit score. For example, if you owe $4,000 and have $4,000 in total available credit, your ratio is 100 percent (4,000 ÷ 4,000 × 100), which is bad. If, however, you owe only $1,000 but have $4,000 in available credit, your credit utilization rate is a much better 25 percent ($1,000 ÷ $4,000 × 100). Lower is preferred because lenders don’t want you regularly spending all the money you have available through credit—it’s too likely that you’ll default and not pay them anything
