Reducing your balances on credit cards and other revolving credit accounts is likely the better option to improve your credit utilization rate, and, subsequently, your credit scores. Consistently making on-time payments against your debt will also help you build a positive credit history, which can have additional benefits for your credit history and, by extension, your credit scores, too.
How much you spend on credit repair depends on how involved you want to be in the process. If you hire a credit repair company, expect to pay a setup fee of up to $100 and monthly service fees of up to $150 for as long as six months. If you invest the time to repair your credit on your own, the credit repair process is free. Credit repair software that costs between $30 and $400 can help you draft letters to creditors and credit bureaus.
