The answer is more than likely “YES”.
Most consumers with good to excellent credit can pick up the phone and request a credit limit increase on their credit card. What’s this do for you?
In the FICO scoring model, your credit score is affected if the amount of credit used is close to the total amount of credit available on your card. You are considered to be an “at risk” consumer because you can easily max out your credit card. By raising your credit score you will increase the available amount causing your credit score to increase.
Another reason for trying to get your credit limit increased is that it will make it easier to get a loan. By not using all your available credit, you are seen as financially responsible and your credit score increases. This makes it a lot easier to get approved more another credit card, car, or mortgage.
Having a higher credit limit will help in emergencies. You never know when something might happen and you don’t have the cash to cover it. BY not having the credit you could be out of luck.
Bottom line is that if you are financially responsible enough, increasing your credit limit on your credit cards can help in the long run.
