> I'm fairly confident that is due to the balance on my CCs varying when the score is calculated

Yes. It feels wrong that the current balance of credit cards is considered debt. It should only be considered debt once (if) you start paying interest on it. So if you pay it off fully every month, it shouldn't be seen as debt.

But whatever, they consider it debt so it can make the credit score swing up and down a lot. I see this every late summer when I pay my childs school bill for the upcoming year on a credit card. It is a very large amount so suddenly my credit utilization goes up and my credit score drops around ~70 points. Then a month later I pay it off and the credit score goes back up the same ~70 points.
