The best way to improve one's credit score is by always paying bills on time. The higher the score - typical range is 300-850 - the better. Just 28 percent of Americans knew that a credit score of at least 700 is generally required to qualify for a low-rate mortgage (a 760 score may result in even lower rates).
More than a third did not know insurance companies often use credit scores to approve coverage and set rates. Less than three-fifths knew that regularly maxing out a credit card, even if paying bills on time, lowers credit scores.
In addition, 79 percent believed incorrectly that credit scores are available free once a year. That's true of credit reports only (see www.annualcreditreport.com). Consumers generally have to pay for their scores, about $15 each.
