Wondering how many credit cards you should have? It’s not really the number of cards that matter but how well you manage them. The moment you find yourself having trouble tracking when your payments are due, the fees for the year, the interest rate, and the balance, it can be difficult to handle more than one card. There would be unnecessary fees imposed on you due to your inability to make timely payments, which can negatively impact your credit score. Before applying for another card, ask yourself if it would be worth it.
