The credit card limit is the maximum amount of money you can spend using your credit card. It gets extended by the lender and contractually agreed upon by the credit cardholder. With American Express cards, no preset spending limit means you will not have a predefined monthly credit limit when you are approved for the card, but it does not mean you can spend an unlimited amount. Your credit limit will depend on your credit history, debt level, income, and payment history on other American Express cards. So, you won’t know your American Express credit limit until you’re approved for an account. Learn how to check your credit limit on your American Express card and how to request a limit increase online or by email.
