<prompt> Human: I have an old card since HS from a small local bank with 500 limit. Now that Im out of college I have two other credit cards with Chase at 5000 and 8000 limits. Is it worth increasing the limit on my old credit card? I almost never use this card, its hooked up to my Uber account so I use it at least once every other month. Or should I just cancel it?  <response>: Increasing the credit limit will decrease your total utilization ratio, which will increase your score, though by how much is hard to say.Dont cancel it, as it will significantly decrease the average age of account, which will negatively impact your credit score.
