How bad is it to have a lot of credit available but not used?
Unless you have a history of over-using credit (i.e. you've gotten yourself into debt trouble), then I think that the banker is giving you bad advice in telling you to get your own credit limit reduced.  Having more credit available to you that is left unused will make your utilization ratio lower, which is generally better for your credit score, according to this article on CreditKarma.com.  The "sweet spot" seems to be 1-20% utilization of your total credit.  (But remember, this is only one factor in your credit score, and not even the biggest-- having a long history of on-time payments counts the most.) My own personal experience seems to bear this out.  I have two major credit cards that I use.  One card has a high credit limit (high for me anyway) and I use it for just about everything that I buy-- groceries, gas, durable goods, services, you name it.  The other card has a limit that is about 1/3 of the first, and I use it for a few recurring bills and occasional purchases where they don't take the first card.  I also have a couple of department store cards that I use rather infrequently (typically 1 purchase every 3 months or so).  At the end of each month, when the respective statements post, each card has a balance that is 15% or less of the credit limit on that card.  I pay off the entire balance on each card each month, and the cycle repeats.  I have never been late on a payment, and my credit history for all of these cards goes back 10 years.  My credit score is nearly as high as it can go.  If having unused credit were a detriment, I would expect my score to be much lower. So, no, having "too much credit available" is not going to hurt you, unless you are not using it at all, or are tempted to abuse it (use too much).  The key is to use common sense.  Have a small number of cards, keep them active, spend within your means so you can pay off the balance in full after the statement posts, and never be late on your payments.  That's all it takes to have good credit.
