There are multiple credit scores that are calculated differently and used by different lenders. FICO scores range from 300 to 850, while VantageScore ranges from 501 to 990 with letter grades. Consumers can check their credit reports for free once a year from each credit bureau, but will need to pay a fee to access their actual credit scores from the bureaus. Maintaining good credit health through on-time payments, low credit utilization, and a variety of credit products can help improve credit scores over time.
