Average Age or Oldest Age or Both (credit cards)

[desert_phoenix]

I know the oldest age matters for a credit card effects your credit score, along with available credit and utilization ratio. What about average age?

I am simplifying my credit card usage and I had a "use this if this purchase does not fit into any category for more" 1.5% capital one card.  I now have a 2% cashback on everything card.  Is it going to hurt my credit in any real way to close the 1.5% card?

I have a ~15 year old USAA one that I only use on a couple purchases a year to keep active and is my oldest by far.  All my other cards are less than 5 years old.  Since I never have a reason to use the 1.5% card (i have two no FTF cards and beat it by at least .5% or more on every purchase), I just wanted to know if there was any reason at all to keep it open.  The only other difference is the 2% card I just opened has a 10k limit and the 1.5% card has a 15k one, so I guess my available credit ratio would drop slightly.

I am also fine to just keep the 1.5% one in the drawer with the USAA one I never use, but figured it doesn't hurt to query others on this.

I've got two cards over 25 years old, and another pretty close behind. I'd have to go look it up to find out the exact number.

Average age of accounts is FAR lower, as I did churning for awhile.

Cards stay on your report for 7 years after being closed. In other words, you won't see the age hit for 7 years. In the meantime, your other cards are aging.

That said, it's easy to "sock drawer" a credit card and set a reminder.
