Justifying a 30 point drop in credit score
My credit score recently dropped from ~760 to ~730 according to Equifax and Experian. According to Equifax, the things that could have hurt it are
my credit utilization went from 12% to 15%
my total balance increased (similar to 1)
the average age of my accounts decreased from 2.75 years to 2.4 years
Does this seem like a reasonable decrease based off of these things? I'm new to all of this so genuinely not sure.
Also, not too sure why my account age decreased this month since the last negative change to my credit card age was over 2 years ago when I deactivated a card?
