Credit score consistently drops after every payment cycle
My finances have been pretty tight lately. I recently broke up with my long-term partner and have been paying for all of my housing expenses on my own. I also have/had some trips and other fun things planned (pre-breakup) that are a bit costly, so I've been spending quite a bit.
My credit score has dropped from 720 to 671 since March. I have a Visa and Amex. I never go past the limit (Amex doesn't have a pre-set limit) and autopay the full statement balance every cycle. My Visa is over 10 years old and my Amex is relatively new. I got it last summer. I also pay my rent, utilities and bills each month.
Credit Karma says that my utilization is poor. My Amex statement last month was nearly $3k, and I paid it off in full. I've been trying to split payments between both cards so I'm not overloading one or the other. Sometimes I break the payments up into two so I can have enough money in hand during the week. The other day, as soon as the payment was deducted from my checking account, my score dropped another 18 points.
What exactly am I doing wrong here? It's so frustrating. If I use the cards too much, I'm punished. If I'm not using them enough, I'm punished.
Thanks in advance for any help!
