How is my credit limit calculated? How do I know how much money I can borrow maximum. If I need...

Generally, a spending limit on a card is based on the factors like your reported annual income, your payment history and your account duration. If you plan to obtain a card with a high limit and charge $100,000 right at once, the chances are this transaction will not be approved. You may consider credit cards with no pre-set limit like Preferred Rewards Gold and One from American Express. The great point about these cards is that they have no pre-set limit, however before making some big purchases, contact the issuer and ask whether you'll be approved to charge this or that sum on your card. You may also consider Capital One Platinum Prestige Card that offers a high spending limit to credit applicants. Check through the offers and apply for the card that suits you most!
