Most consumers believe if they pay their bills on time, they need not worry about their credit score. Oftentimes, it is a rude awakening when they apply for a mortgage loan, car loan, or any revolving credit to learn they are not going to get the lowest rates available due to their credit score. This is because paying bills on time only accounts for 35 percent of your credit score. The remaining 65 percent is spread out among other factors that impact your credit score.
