The credit limit is the maximum amount of money you may charge on your credit card. This limit is mainly determined by your income and your credit risk. So, it depends on the terms of your card and may be changed according to your credit history. If you prove to be a good credit payer, you'll be given a higher limit. That's why before applying for a card consider your credit report and estimate your financial state. To get a limit of $7,000 your current score must be high and your history must be good. If it is really so, you can apply for the best credit cards
with the highest limits. Keep in mind that the limit is not a constant figure, it may change as your score changes. And it may not only go up, but also go considerably down. That's why if you want the higher limit you must use your credit lightly, pay all the bills on time and keep your score as high as possible.
