NEW YORK (CNN/Money) - It turns out that learning more about your credit rating could help you boost your score and even save you some money. "Unfortunately, most consumers still do not know basic facts about credit scores and their financial significance," according to the Consumer Federation of America Executive Director Stephen Brobeck. In fact, according to a recent poll conducted by Opinion Research Corp., only 27 percent of consumers understand that scores measure credit risk. The truth is, your credit score, sometimes called a FICO score, is a number based on the information in your credit file that shows how likely you are to pay a loan back on time -- the higher your score, the less risky you are. There are three major credit bureaus: Experian, Equifax and TransUnion. The credit bureaus write up your report based on any information they received about you from companies that gave you credit in the past, such as your payment history, the length of your credit history, the types of credit you have and amounts owed. From that report, a credit score is derived -- which ranges from 300 to a perfect 850. That score is a quick way for lenders to assess how risky you are as a potential borrower. The higher your score, the less risk you pose to lenders and the more likely it is that you'll get their best available rates. Consumers with scores above 700 are usually charged relatively low rates, and those with scores above 760 are charged the lowest rates. Consumers with scores below 600 are typically charged relatively high loan rates, and if your credit score is really bad, you may be not be able to borrow at all. Any late payments you made will lower your score, but establishing or re-establishing a good track record of making payments on time will raise your score. Beth Givens, director of the Privacy Rights Clearinghouse, says, ideally, you want your score to be well above 620, that's a drawing line for creditors. (The median credit score in the United States. is 723.) Credit card provider Providian Financial estimated that consumers with an average score would reduce card finance charges by $76 annually if they raised their score by 30 points. "If [all] consumers were to raise their credit scores by only 30 points, on average they would save $16 billion on lower credit card finance charges alone," said J. Christopher Lewis, Providian's chief public policy officer. Under the Fair and Accurate Credit Transactions Act , you can obtain one annual free copy of your credit report.

"Those who have obtained their scores know significantly more about credit scores than those who have not," noted CFA's Brobeck. And once you know your score, you can follow these tips from myFICO to improve your rating: Pay your bills on time. Delinquent payments can have a major negative impact on your score and the longer you pay your bills on time, the better your score. For example, someone with an average credit rating of 707 can raise their score by as much as 20 points by paying all their bills on time for one month.
