A fico score is a number that is calculated based on your credit history. This is a calculation used by credit bureaus to determine your credit worthiness to lenders. The calculation takes into consideration present and past debt history and your ability to pay your creditors on time. Many agencies have begun using the fico score for everything from employment to insurance and this can have a big impact on premiums that you pay and on loan rates you will receive. You are allowed to request one free credit history report a year. This report will reflect your current fico score.
