How does having multiple credit cards affect your credit score?

Multiple credit cards can impact your credit score depending on factors like your borrowing history and risk to lenders. Carefully maintaining a good credit score is crucial when having multiple credit cards. However, having newer cards can lower your credit score as it brings down the average age of your credit history. Factors that affect your credit score include payment history, debt-to-credit ratio, average age of credit cards, types of credit, and new credit accounts.
